    Tested: 2021 Mercedes-Benz E450 Grows Sweeter with an Inline-Six

    Of the myriad E-class models that Mercedes-Benz offers, the six-cylinder E450 sedan is perhaps the most traditional example of Benz’s long-serving mid-size offering. For the 2021 model year, the E450 becomes an even more compelling midrange option, thanks to the adoption of Benz’s latest turbocharged 3.0-liter inline-six engine in place of the previous twin-turbo V-6.

    2021 Mercedes E-Class Is Refreshed, Adds Hybrid

    E450 All-Terrain Gives Benz’s Wagon a Lift

    The new powerplant comes as part of a mid-cycle update that also brings revised styling and updated technology features to the full 2021 E-class lineup. And in every objective category, this inline-six is a winner. Its 362 horsepower and 369 pound-feet of torque are identical to the outgoing V-6’s. But it’s a fully modern design, incorporating a 48-volt hybrid system with an electric motor-generator that can add up to 21 horsepower and 184 pound-feet to assist the engine while the turbo spools up.

    HIGHS: Silky inline-six, cushy and composed ride, luxurious cabin.

    Aided by a standard nine-speed automatic transmission and 4Matic all-wheel drive, our test car ran to 60 mph in 4.3 seconds and completed the quarter-mile in 12.9 seconds at 108 mph. Both of those times are 0.2 second quicker than those we recorded for a 2019 E450 4Matic sedan. The new engine is also more fuel efficient than the old V-6, earning a 26-mpg combined estimate from the EPA versus the previous 23 mpg. Remarkably, the E450’s combined rating is now 1 mpg greater than that of the far less powerful four-cylinder E350 4Matic model. We averaged 24 mpg.
    In the stately E-class, the new six’s smooth power delivery is as welcome as its efficiency. While the engine will emit a sonorous growl when pushed hard, it idles quietly enough that you hardly can tell that it’s running. And the 48-volt hybrid system allows for a remarkably unobtrusive start-stop operation, shutting off the engine as you approach an intersection and imperceptibly starting it back up when you set off.

    LOWS: Overly complex infotainment system, long stopping distance.

    We won’t knock the E450 for not being very sporty; it wafts down the road like a true luxury sedan should, which makes it easier to enjoy its sumptuous and beautifully trimmed cabin. Ride quality is buttery smooth with our test car’s combination of standard 18-inch wheels with all-season tires (19s are optional), adaptive dampers, and optional $1900 air springs. There is a Sport mode that tightens up the steering action and body motions, but the E450’s composure feels best at a relaxed cruise. Although our test car posted a respectable 0.88 g of grip around the skidpad, its long 187-foot stop from 70 mph is closer to what we’d expect from a full-size pickup.

    Benz’s latest MBUX infotainment system is also included in the E-class’s most recent update, yet it often feels like a step backward from the previous COMAND system in terms of ease of use. Compared to the old setup’s relatively straightforward central control knob, the new system’s combination of a touchscreen, a touchpad on the center console, voice control, and a mix of touchpads and buttons on the new steering wheel make for a complex interface. The displays have a crisp, modern design, but the learning curve for navigating the system’s many sub menus is steep.
    Yet, we won’t hesitate to say that the E450 feels worth its $63,050 starting price—a $5250 upcharge over the E350 4Matic. It may not be as exciting as AMG’s more-powerful versions of the E-class. But even at our well-equipped example’s $76,140 as-tested figure, the smooth, effortless power provided by Mercedes’s new inline-six only adds to the E450’s impressive levels of luxury and refinement.

    Tested: 2021 Mercedes-AMG E63 S Wagon Simply Hauls

    If you remember when the station wagon was the quintessential American family car, congratulations—you’ve been around for a while. That means you’ve seen wagons all but disappear from the nation’s driveways over the years and then more recently reappear in smaller numbers dressed like SUVs, with plastic body cladding and jacked-up suspensions. But that fate has not befallen the 2021 Mercedes-AMG E63 S wagon, which remains a low-riding, sticky-tired, 603-hp raised middle finger to the current faux-SUV wagon trend.
    AMG’s E63 S wagon is a family hauler from hell that can blaze down a twisty road like a supercar yet handle any domestic task you throw at it. Schlep the kids to school? Done. Pick up lawn fertilizer from Lowe’s? No problem. Dust a new Mustang GT500 to 60 mph? Hold my Starbucks. How could we not love this car?

    HIGHS: Supercar performance, wagon practicality, wonderfully luxurious.

    2021 Mercedes-AMG E63 S Does It All

    Tested: 2018 Mercedes-AMG E63 S Wagon

    For the record, Mercedes has caved to the public’s predilection for SUV-styled wagons with the 2021 E450 All-Terrain. But the company also has a long history of offering E-class wagons that have been hot-rodded by AMG. The current-generation E63 S wagon first arrived for the 2018 model year. For 2021, it’s undergone a mild update along with the rest of the E-class lineup.
    Only a few things about the E63 S have changed with the refresh, which we and lead-footed moms and dads everywhere should be thankful for, given how exciting this car already was. Remember that the E-class’s platform undergirds AMG’s gut-punching GT63 S four-door coupe, so the wagon has some serious performance chops.

    Mercedes-AMG

    The hardware that supplies the thrills is virtually unchanged from last year’s model. The E63 S is powered by a familiar 603-hp twin-turbo 4.0-liter V-8, which sends its 627 pound-feet of torque through an AMG-tuned nine-speed automatic transmission and 4Matic+ all-wheel-drive system. The wagon rides on standard air springs and adaptive dampers and grabs the pavement with 20-inch Michelin Pilot Sport 4S summer tires, sized 265/35R-20 in front and 295/30R-20 at the rear. There are five conventional driving modes—Comfort, Sport, Sport +, Individual, and Race—plus a Drift mode that disconnects the front axle and directs the power solely to the rear tires, enabling lurid powerslides suitable only for locations far from public roads. Top speed is electronically limited to a claimed 180 mph.

    LOWS: Fussy steering-wheel controls, complicated infotainment system, no third row of seats.

    The most obvious changes for 2021 are a new front fascia and toothy AMG GT-like grille. Mercedes’s latest MBUX infotainment system also has been added, as has a new AMG sport steering wheel. None of these updates alters the E63 S’s racy feel or awesome performance. It flashes to 60 mph in just 3.0 seconds, shoots through the quarter-mile in 11.1 seconds at 122 mph, circles the skidpad with 1.00 g of grip, and stops from 70 mph in 150 feet.

    Mercedes-AMG

    Better still, all of that performance is easily accessible and contained within a car that’s refined enough to drive every day. It takes only a couple of button pushes to access the launch-control system for eye-widening takeoffs. Hold the right pedal down and the V-8’s exhaust note cuts with buzzsaw intensity as it approaches its 7000-rpm redline. Ride quality is almost supple with the suspension in Comfort mode, although the big Michelins do clomp solidly over pavement seams. We liked driving the E63 S best in Sport, where its clipped ride motions seem in perfect synch with the sharp, weighty steering and responsive carbon-ceramic brakes, which were an $8950 option on our test car. The E63 S wagon’s spectacular bandwidth—its ability to both effortlessly haul ass and comfortably haul the family—means it remains solidly competitive with the two other mega-performance wagons on the market, the Audi RS6 Avant and the Porsche Panamera Turbo Sport Turismo. Sadly, the AMG version nixes the third row of seats found in the E450 All-Terrain, but its 35 cubic feet of cargo space does make it highly versatile.
    If only we felt as enthusiastic about the updates made to the E-class’s richly appointed cabin. The latest MBUX system is complicated, and its multi-layered menus enable you to control almost too much of the in-car experience—ranging from the intensity of the front-seat massage function to the instrument cluster graphics to whether it will remind you to call your mom every Tuesday on your commute home. We’re not kidding about that last one, which is at least a feature that can be shut off. The system also contains AMG-specific gauge displays and a performance data logger.

    Mercedes-AMG

    MBUX allows you to control all of this information in multiple ways, including through the large touchscreen in the center of the dashboard and via the center-console touchpad. You also can use the numerous controls on the new-for-2021 AMG steering wheel, the four-spoke design of which reminds of a double-neck electric guitar, only the wheel is even more of a handful to use. The wheel’s spokes are packed with small switches and a pair of tiny touchpads that together operate the adaptive cruise control, gauge displays, and the central touchscreen. Two cheap-feeling plastic knobs below the spokes control the drive modes. There’s nothing wrong with how those knobs operate, but we found the spoke-mounted touchpads to be fussy and overly sensitive when swiping to adjust even minor things like the info screen in the cluster or the radio station. A car as driver centric as this deserves a more user-friendly setup.
    Prices for the E63 S wagon start at $113,445. Our test car, with its optional carbon brakes, massaging front seats, blackened exterior trim, Driver Assistance package, adaptive headlamps, and several lesser extras, came to $137,405. While it isn’t cheap, we think moms and dads should consider that price as an opportunity to improve their family’s finances. After all, purchasing an E63 S wagon saves you from needing to buy both a supercar and something more practical, like an SUV. With AMG’s long-roof E-class, you get both cars in one.

    2021 Land Rover Defender 90 Puts the Defender In its Purest Form

    Supercar makers rarely boast about ground clearance, breakover angles, or wading depths. Acceleration numbers for rugged SUVs are barely more relevant. Yet, being shorter and lighter than its four-door sister, the new two-door Defender 90 is set to be the quickest factory-produced version of Land Rover’s classic off-roader.
    Select the range-topping 395-hp P400 six-cylinder engine, and we expect the 90 to dispatch the zero-to-60-mph benchmark in just 6.0 seconds, continuing to an electronically limited top speed of 120 mph. When we recently timed a seven-seat version of the long-wheelbase that was 110 to 335 pounds heavier, according to Land Rover’s numbers, and fitted with a drag-inducing roof rack, it ran to 60 mph in 6.3 seconds and blew through the quarter-mile in 14.8 seconds. Nobody is likely to buy a Defender 90 to win a stoplight grand prix, but it might mean owners will take victories in a few.

    Tested: 1994 Land Rover Defender 90

    Land Rover Defender Two-Door Coming to U.S.

    Tested: Defender 110 Refines an Off-Road Icon

    Although mighty, the P400 engine isn’t one of the Defender 90’s experiential highlights. The 3.0-liter inline-six comes from JLR’s Ingenium family and features both a mild amount of electric assistance—through an integrated 48-volt starter-generator—as well as an electric compressor to quicken responses before the turbo builds boost. It is certainly effective, with the sensation of acceleration heightened by the nose-up attitude the 90 takes on its soft springs. But the engine is short on refinement, sounding loud and diesel-like under gentle loads and becoming coarse at higher revs.
    To be fair, the powerplant’s lack of manners are only really noticeable because the rest of the 90 is so good. It cruises remarkably quietly for something with such a blunt aerodynamic profile and such sizable tires, road and wind noise staying impressively low even when cruising at an indicated 80 mph. Although upright, the seating position is comfortable over long stints behind the wheel, and the uncluttered dashboard is a model of clarity. Ventilation and drive-mode buttons are grouped in a binnacle next to the gear selector, with other most functions controlled by the 10-inch touchscreen above. We’ve been plenty rude about JLR’s clunky, confused, and often oxymoronic InControl infotainment, so we are happy to report that the Defender’s Pivi Pro system—which will soon roll out throughout the range—is clearer and much more intuitive.

    Land Rover

    Although smaller than the 110, the Defender 90’s cabin does not feel cramped. The rear seats are positioned slightly higher than those in the front, and although access to the back requires an awkward scramble, both legroom and headroom are entirely viable for adults. The option of what is effectively a fold-up jumpseat in the front means the 90 can carry six passengers—all hail the return of the front bench seat—although anyone in the middle up front will have to bend their knees around the dashboard console. Cargo space has obviously been reduced compared to the 110, but there are still 16 cubic feet behind the rear seats.
    The P400 we drove in England was in fully loaded X trim, set to start at $82,560. The X model brings both plush trim and a near fully ticked set of option boxes, including an upgraded Meridian audio system and a set of gray-faced 20-inch alloys that looked too nice for proper off-roading. The X also gets standard height-adjustable air suspension, with lesser versions of the 90 running on steel coil springs.

    Land Rover

    On road the air springs felt a little firm when asked to deal with urban bumps and potholes, but they were well suited for highway speeds. Although the P400 has a set of Terrain Response modes to allow it to tackle any off-road environment, it lacks a Sport or Dynamic mode, and even moderately rapid progress brings some acute lean angles. Our test car’s Goodyear all-terrain tires could only produce modest grip, with the 90’s stability control intervening hard and early when it sensed any loss of grip. The electrically boosted brakes are also grabby, and the pedal lacks feel. We were also surprised to discover that even in range-topping form the 90 lacks steering-wheel shift paddles. Taking manual control of the standard eight-speed automatic transmission needs to be done through the central shift lever.
    Having shown us one extreme of the 90 clan with the P400 X, Land Rover also let us experience something far closer to the other, a P300 riding on coil springs and with interior trim clearly chosen for durability rather than niceness. We got to drive this on a route around the grounds of Eastnor Castle in Herefordshire, this being the place where Land Rover has tested the off-road credentials of its vehicles (and those of its competitors) pretty much since the company’s foundation.

    Land Rover

    The P300’s 2.0-liter turbocharged four-cylinder engine soon proves to suit the Defender’s doughty character perfectly. With 296 horsepower, it’s still capable of delivering reasonable acceleration; we expect it to come in under 8.0 seconds, still entirely respectable for a vehicle this shape and size. It is also happy grumbling along at low revs in gelatinous mud. Its peak 295 pound-feet of torque is available on a flat plateau that stretches from 1500 rpm to 4000 rpm.
    You won’t be surprised to learn the P300 proved mighty in its development playground. The combination of low-range gearing, locking center and rear differentials and the traction-boosting magic of the Terrain Response system’s Mud and Ruts mode allowed it to slither and grind its way along some of Eastnor’s tracks while barely working hard. Steel-sprung clearance wasn’t quite as good as it would have been with fully raised air suspension—8.9 inches versus 11.5 inches—but it was still more than adequate to clear sizable obstacles. And with four-wheel independent suspension, the diffs are tucked up in the middle instead of dragging along with the axles, as in the old Defender. (And the current Jeep Wrangler.)

    The Defender 90 is cheaper than the 110, but not by much. The entry-level $47,450 P300 is $4400 less than the equivalent 110, but the difference is actually less than that: The longer-wheelbase model brings standard air suspension, which is a $1600 option on the base 90. Further up the tree, the difference is even less, with the 90 X only being $2500 less than the 110.
    While some may choose the two-door Defender to secure that modest discount—or to fit within the confines of an exceptionally short garage—most 90 buyers will be drawn by the desire to experience the Defender in its purest form.

    2021 Mercedes-Benz S-Class Advances the High-Tech Luxury Sedan

    Upmarket car buyers are showing an increased preference for SUVs pretty much everywhere in the world, yet the S-class remains—explicitly—the flagship model for Mercedes. A new generation of the Sonderklasse always serves as both a range-topping luxury sedan and a tech showcase for features that will soon trickle down to lesser Benzes. Mercedes is rightly proud of the many innovations that previous S-classes introduced, including anti-lock brakes (1981), stability control (1995), radar cruise control (1998), and all-LED exterior lighting (2013). There have been a few that didn’t trickle so much, too. Remember the “parking wands” that rose from the rear corners of the 1991 W140 generation to make it slightly easier to back that behemoth trunk toward a parking spot?

    Why the Mercedes-Benz S-Class Endures and Shines

    2021 Mercedes S-Class vs. BMW and Audi Flagships

    Mercedes Fills 2021 S-Class with New Technology

    While there is indeed an abundance of new features in the new S-class, the first impression is of what’s missing—namely, bravado. This generation (W223 in Benz code) is less ostentatious than its predecessor, lacking the old car’s baroque detailing and incorporating smaller, more modest headlights and taillights. The lack of flashiness disguises an insubstantial increase in size over the outgoing version, with the W223 gaining 1.3 inches in length and sitting on a wheelbase stretched by just 2.0 inches. Mercedes is particularly proud of the ultra-low drag coefficient—as little as 0.22—boosting efficiency and improving refinement. Tesla-like door handles sit flush within the body, popping out when the car is unlocked or they sense the presence of an approaching smart key.

    Mercedes-Benz

    There’s more Tesla-fication within the cabin, with a vast 12.8-inch touch-sensitive OLED screen dominating the dashboard. At first glance it actually looks like an open laptop has been left on the center console, and this screen is the primary interface for almost all functions beyond basic driving. Even the climate controls are now rendered digitally. This means that Mercedes’s cabin designers have surrendered much of the prime real estate where they previously demonstrated their craft so well. The last S-class had four machined air vents and a mechanical clock in the space now taken over by the glass interface. But the rest of the cabin showcases plenty of the old craftsmanship, with wall-to-wall hide and some beautiful wooden trim, plus color-configurable LED lighting around all interior panels. There is also a fingerprint sensor to allow for rapid changing of driver profiles or even authentication for purchases made through onboard apps.
    Two versions will initially be offered in the United States market. The S500 gets a 429-hp supercharged and turbocharged 3.0-liter inline-six, and the S580 upgrades to a 496-hp twin-turbo 4.0-liter V-8, with both engines incorporating 48-volt hybrid assistance. We drove the S580 first, on a route from Stuttgart to Mercedes’s proving ground at Immendingen via a stretch of unrestricted autobahn. In the ordinary course of vehicle testing, this would lead to an immediate attempt to find the speed limiter and stay on it for as long as possible, but with the S-class the chance for higher-than-normal velocities was more useful in demonstrating the car’s exceptional noise insulation. At 80 mph, more noise was coming from other traffic—muted by the windows’ dual panes—than the car itself. Only above 140 mph did the commencement of wind noise from the tops of the doors disturb the serenity. And yes, we did confirm the presence of a 155-mph governor. U.S versions will be restricted to a more leisurely 130 mph, says.

    Mercedes-Benz

    The V-8 rarely raises its voice, even as it creates forceful acceleration. In the most aggressive Sport Plus dynamic setting (a mode that feels at odds with the S-class’s character and purpose), the engine stayed hushed under all but stamped-throttle progress. And even then, the V-8 sounded distant and muted. Suspension settings are similarly comfort-orientated, with both adaptive dampers and air suspension standard. The big Benz sits 0.7 inch lower in Sport Plus mode, yet the ride remains impressively pliant, if lacking the firmness normally associated with sports sedans.
    We also got to sample the optional E-Active Body Control system, which adds both a road-scanning camera and an active anti-roll system. The latter employs a hydraulic system pressurized by a 48-volt pump. This can neutralize body roll—which it does effectively—and will also offer Curve mode, leaning into turns like an oversized motorbike. Grip levels are high, and on dry tarmac, the standard 4Matic all-wheel drive delivered unbreakable traction.
    At lower speeds, the S580 also showed off another of its innovations: a new rear-axle steer system that can turn the rear wheels up to 10 degrees. Mercedes says this reduces the turning circle of the regular wheelbase S-class to just 35.1 feet, which is one foot smaller than the turning circle of an A-class sedan. The sensation of the system working is initially odd, as the rear axle can be felt moving out as the front turns in. But the increase in maneuverability is obvious and impressive. The 10-degree rear-axle system will only be offered on the S580 with the Executive Line pack. The AMG Line trim (available with both engines) brings a less aggressive 4.5-degree version that delivers a 38.1-foot turning circle. Above 40 mph, both systems offer much smaller degrees of in-phase steering to boost stability.

    This S-class is designed to eventually deliver hands-off autonomy. We got to experience a Level 3 demonstrator—although on a test track and only from the passenger seat—but Mercedes’s existing Drive Pilot smart cruise control is still able to regulate distance and follow lanes. One of the display options on the reconfigurable digital dashboard now relays what this system can “see” in terms of lane markings and other road users—distinguishing between cars, trucks, and motorcycles. Drive Pilot handled highway speeds well, but it struggled to deliver smooth stops when dealing with heavy traffic. It also includes automatic speed regulation based on posted limits, although we found that the car missed limit changes several times.
    While hugely impressive as a car, much of the mission for the S-class is as a showcase for new technology. Debuts include an enhanced version of the augmented-reality navigation that we have already seen on the GLE and revised E-class, now capable of projecting directional arrows onto the windscreen’s head-up display. The cloud-based “Hey, Mercedes” voice assistant has more capability here than in some other Benzes, simply because there are more toys for it to control. Saying “I’m stressed” will trigger the car to offer you a massage program. The huge central touchscreen is running a new version of Mercedes’s MBUX infotainment system, which looks nicer and is backed by a claimed 50-percent increase in processing power, but some lesser functions are still buried beneath several layers of menus.

    The 12.3-inch dashboard instrument screen also gets a pioneering feature. It has 3D display capability, which presents slightly different images to each eye to give a sense of depth. The effect is striking, especially when the dash is switched to navigation and you find yourself looking at what seems to be a relief map. But beyond ornament, it doesn’t add anything to the driving experience, and Mercedes admits it may make some drivers feel queasy. Fortunately, it can easily be switched to conventional 2D.
    A drive in the entry-level S500 confirmed that U.S. buyers won’t be giving up much in terms of either performance or experience by selecting the smaller engine. Low-down responses feel very nearly as keen as those of the V-8 thanks to the immediacy of the electrically driven supercharger and the integrated electric motor-generator, which can contribute up to 22 horsepower and 184 pound-feet of torque. The six’s high-rev rasp, although subdued, is at least as aurally interesting as the V-8’s muted roar. A quiet stretch of autobahn revealed that only above 120 mph does the S500 start to feel noticeably slower than the S580, taking considerably longer to encounter its 155-mph governor.
    Both S500 and S580 will reach the U.S. during the first half of next year. The best toys will be reserved for the various option packages, but the standard specification will include the OLED dashboard interface, Burmeister audio, and the full suite of driver-assistance systems. Beyond that, other versions will include an AMG with a brawnier V-8, a plug-in hybrid that should offer class-leading electric range, and ultimately a Maybach version, which we believe will continue to offer V-12 power. But even in its most basic form, the S-class continues to represent Mercedes at its best.

    Tested: 2021 Toyota Sienna Sheds Minivan Stereotypes

    The new 2021 Toyota Sienna appears to want to undo the stigma that minivans have suffered for decades. To trick the eye into thinking the Sienna is an SUV, the hood has been raised and the base of the A-pillar is pulled back. The sheetmetal around the rear wheels bulges and connects to a bone line that runs along the side of the van. An aggressive-looking minivan might not be something anyone asked for, but we’ll take it.
    Bolder on the Outside, (Mostly) Better on the Inside
    The sliding doors still announce that it’s your turn to carpool, but the Sienna’s new interior is far more modern and driver-focused than its predecessor’s dated design. A bridgelike floating center console flows out of the dashboard and leaves a large and practical storage area below. Four of the Sienna’s 18 cupholders are housed atop the console, and we like that Toyota kept a real shifter rather than adopting the fashionable and unnatural rotary-knob and push-button setups found on the Chrysler Pacifica and Honda Odyssey.

    HIGHS: An aggressive-looking minivan, improved refinement and road manners, stellar fuel-economy figures.

    2021 Toyota Sienna Looks Wild, Goes Hybrid-Only

    Why the Toyota Sienna and Venza Are Hybrid-Only

    Behind the front seats, the new Sienna stops pretending it’s not a minivan. There’s comfortable seating for seven—or eight with the stowing center seat—and legroom has increased in the second and third rows. The second-row captain’s chairs that recline and look like they’re out of a dentist’s office slide back and forth more than before and provide limo-like accommodations. Those chairs don’t come out nor do they fold into floor, which limits how much you can pack into the Sienna. The last-generation Sienna had removable seats and a massive 150 cubic feet with the third row stowed and the second row removed, far more than the new Sienna’s 101 cubic feet. Cargo volume behind the second and third rows is down by 12 and five cubes, respectively. Toyota has decreased the effort needed to fold and unfold the third row into the floor, and we can confirm that the operation is nearly effortless.
    More Refined on the Road, More Efficient at the Gas Pump
    Following the built-in vacuum trend, there’s a built-in vacuum, and like the original Toyota Van from 1984, there’s a small refrigerator in the center console. The Sienna is the only minivan with foot-activated power sliding doors. Kick under the door, and the door slides open. A full roster of driver-assistance technology is standard, including adaptive cruise control and lane-keeping assist.

    LOWS: Hybrid powertrain sacrifices acceleration to fuel economy, second-row captain’s chairs cannot be removed, some brake fade.

    The Sienna has moved to Toyota’s TNGA-K platform, an architecture that also underpins the Highlander and RAV4. More solid than before and with a 1.2-inch longer wheelbase, the Sienna also gets a new multilink rear suspension that replaces a less sophisticated twist-beam axle. Handling is more secure, and the steering is quicker and more precise.
    At the track, our all-wheel-drive Sienna Platinum posted an identical 0.79 g on the skidpad as a 2019 Sienna AWD we tested. The new one’s stopping distance from 70 mph also grew by five to 188 feet versus its predecessor, and we noticed moderate brake fade. Still, minivan shoppers will likely care more about the Sienna’s newfound refinement than its at-the-limit handling.
    Customers are also likely to care a lot about the Sienna’s fuel economy, which is why the Sienna is now exclusively a hybrid. In place of the old 296-hp 3.5-liter V-6 is a 2.5-liter inline-four that couples with two electric motors to make 245 horsepower. Nearly a second slower to 60 mph than the V-6 (7.7 seconds versus 6.8), the hybrid system delivers strong-feeling acceleration from low rpm. The hybrid’s fuel economy is considerably better than its predecessor’s 19 mpg city, 27 highway, and 22 combined. The front-wheel-drive hybrid is EPA rated at up to 36 mpg in all three metrics, which is also considerably higher than its V-6-powered rivals. The all-wheel-drive model loses a single mile per gallon in the city and combined ratings. In our hands, we averaged 29 mpg.

    The Sienna still tows up to 3500 pounds, and all-wheel drive remains an option, but instead of a driveshaft, there’s an electric motor powering the rear axle. The Sienna’s 1.9-kWh nickel-metal-hydride battery is packaged under the front seats to avoid compromising cargo space. When sufficiently charged and put in EV mode, the battery allows for pure electric driving for short distances and low speeds.
    Final Word
    Toyota has slightly rejiggered the Sienna’s model lineup, which now starts with the base LE and moves up to the XLE, XSE, Limited, and the top-spec Platinum. Base prices remain relatively close to the outgoing versions and range from $35,635 for the LE up to $51,635 for an all-wheel-drive Platinum like our test car. Although the new Sienna might not change the public’s perception about minivans as much as Toyota’s marketing department hopes, it has the style and substance to challenge the refreshed Chrysler Pacifica, the facelifted Honda Odyssey, and the upcoming Kia Sedona.
