    Chevrolet Corvette Z06 at the 0-to-150-to-0-MPH Speed Test 2023

    From the December 2023 issue of Car and Driver.0–150–0 mph: 22.5 secondsBase: $144,280 | As-Tested: $167,605Power and Weight: 670 hp • 3672 lb • 5.5 lb/hpTires: Michelin Pilot Sport Cup 2 R ZP; F: 275/30ZR-20 (97Y) TPC, R: 345/25ZR-21 (104Y) TPCBrakes, F/R: 15.7-in vented, cross-drilled carbon-ceramic disc/15.4-in vented, cross-drilled carbon-ceramic discThe Z06 is a road-course car, not a drag racer. But its performance here proved that it’s game to trip the beam at your nearest staging lights, cracking off an 11.3-second quarter-mile. The Z06’s launch control is manually adjustable, but we got the best times in auto mode, letting the car learn the surface and adjust its aggression accordingly. By about 144 mph, the numbers climb a digit at a time, so it’s relatively easy to get close to a true 150 mph. As you’d hope, the brakes are stupendous, and it’s all over a lot quicker than it started. The Z06 vanquished its natural foe, the GT3 RS, by almost two seconds, but its margin was narrower against another rival from inside its own brood—the Lingenfelter Corvette ZR1 from 1998, which completed the test in an astounding 23.3 seconds. Think about that: A naturally aspirated C4 Corvette, 25 years ago, could beat a modern Porsche GT3 RS and nearly hang with a C8 Z06. (In fact, the Lingenfelter’s 150-mph time, 15.6 seconds, bested everything at Oscoda except the 911 Turbo.) Makes you wonder what those folks could do with a C8.back to 0-150-0 Speed Test 2023Senior EditorEzra Dyer is a Car and Driver senior editor and columnist.

    Hyundai Elantra N at the 0-to-150-to-0-MPH Speed Test 2023

That’s why Bonneville land-speed cars all look more like the sleek Elantra than the big-winged Civic, and it’s surely one reason why the Elantra N pulled ahead of the Civic by more than five seconds at 150 mph despite its 39-hp deficit. The rorty six-speed manual Hyundai was a handful off the line, requiring a 5000-rpm clutch engagement followed by judiciously managed wheelspin until it hooked up.Then, the driver had to remember that the N allows no-lift shifting—automotive abuse we avoid in testing unless the car has the no-lift feature. From there, it was a smooth ride, with the Hyundai pulling surprisingly hard above 140 mph. The brakes felt stable and strong despite recording one of the longer stops at 710 feet. Yes, the Elantra finished near the bottom of the pack. But we’re tickled that for $34,015, you can buy a four-door family sedan that can take you to 150 mph and back without a shrug.back to 0-150-0 Speed Test 2023Senior EditorEzra Dyer is a Car and Driver senior editor and columnist.

One driver noted, “Put it in Special mode that’s labeled Nürburgring, push on the gas, push on the brake, rev it up, and it goes.” The Golf hit 60 mph in 4.5 seconds, and a buck-fifty requires 33.3 seconds. Since we were only pointing straight, there was little opportunity to touch the capacitive steering-wheel buttons by accident, so that was nice. The Golf’s brakes gave a little wiggle on one stop but otherwise felt the same every time, essentially duplicating the Civic’s stopping performance and erasing 150 mph in 6.2 seconds.True to its origins, the pocket rocket from the land of autobahns felt like it would be happy to stay at 150 mph for as long as we pleased.back to 0-150-0 Speed Test 2023Senior EditorEzra Dyer is a Car and Driver senior editor and columnist.

    Kia EV6 GT AWD at the 0-to-150-to-0-MPH Speed Test 2023

    From the December 2023 issue of Car and Driver.0–150–0 mph: 31.2 secondsBase: $62,925 | As-Tested: $63,100Power and Weight: 576 hp • 4815 lb • 8.4 lb/hpTires: Goodyear Eagle F1 Asymmetric 3 SUV, 255/40R-21 102YBrakes, F/R: 15.0-in vented disc/14.2-in vented disc On a recon run, without the complete array of test equipment active, the EV6 notched a 30.8-second pass, which would have put it ahead of the Supra. Alas, without the granular data, the score from the Russian judge got tossed, and the EV6 officially finished 0.1 second behind the Supra. That is still a quick time, and scrambling to 150 didn’t use as much juice as you’d think—about 5 percent of the battery’s charge per pass, 2 percent of which returns with a regen-friendly gentle stop. When throwing out the anchors in anger, the Kia’s brakes felt good but required a longest-in-test 756 feet of pavement. Launching the EV6 couldn’t be simpler: Press the GT button on the steering wheel to enable all 576 horsepower, brake-torque (which doesn’t seem to do anything, but why not?), and you’re off. Dispatching the quarter-mile in 11.8 seconds, the EV6 is reminiscent of the Bentayga—more motor than brakes but still puts up a nice number at the end of the run. In fact, if the EV6 had been there in 1998, it would have beaten every stock vehicle we tested, including the Dodge Viper. Not bad for a car with zero cylinders.

It’s pretty much all as expected until you hit the brakes and your eyeballs get sucked out of your head.Did we predict that a Mustang would outbrake both the Corvette Z06 and the 911 Turbo S, posting a preposterous 569-foot stop from 150 mph? No, we did not.

    Toyota GR Supra 3.0 at the 0-to-150-to-0-MPH Speed Test 2023

And in the Supra’s case, the low-speed agility that makes it such fun on a twisty road manifests as unsettling jitters at high speeds. The truffle hunting starts at about 120 mph as the Supra nervously sniffs the edges of the lane. It regains its stability under braking, but we were glad for the wide expanse of the taxiway as we neared 150. Launching the Supra was fairly simple—keep the revs low, brake-torque it a little bit, and don’t light up the tires. Compared with its unexpected rival, the EV6, the Supra was notably slower to 60 mph (4.3 seconds versus 3.5) but reeled in the EV at higher speeds. It closed the gap to 0.4 second at 150 mph and then clawed back 0.5 second under braking. Yes, the Supra has strong brakes.

    Porsche 911 Turbo S at the 0-to-150-to-0-MPH Speed Test 2023

Setup was easy: Select Sport mode, which keeps the active front and rear spoilers in their low-drag position, then hit the Sport Response button to increase the launch-control threshold from 4000 to 5000 rpm. After that, hang on for a four-wheel burnout, followed soon thereafter by the quarter-mile mark (10.5 seconds) and 150 mph (13.5 seconds). The biggest challenge in the Turbo S was nailing 150 without sailing too far into the deeper reaches of the speedometer before hitting the spectacular brakes, which were second only to the GT3 RS and the Dark Horse with a 586-foot stop. The Turbo S was the only car here that had us eyeing our taxiway and thinking, “Forget 150. This damn thing could hit 200 mph here.” So we aired up the tires to their highest-speed pressure setting and confirmed that suspicion, sending the Turbo S to 201 mph with room to spare. What a car. What a machine. And so, thanks to a nail in the tire of a Tesla Model S, the Porsche 911 Turbo S won our Silver Jubilee 0-to-150-to-0-mph contest. But even if we don’t wait 25 years to do this again, it looks highly unlikely that an internal-combustion car could win a race to 150 mph and back ever again.

    Car and Driver’s 0-to-150-to-0 Speed Test 2023

    From the December 2023 issue of Car and Driver.Every so often, we get the notion to resurrect a story concept from long ago and produce a modern follow-up. For a variety of reasons, this often doesn’t work out—we figure out that Ferrari 250GTOs have gotten too expensive to huck around Laguna Seca, or John Phillips is banned from Tibet, and that puts the kibosh on that. But every now and then, we page through a favorite story in the vast Car and Driver archives, ask ourselves, “Could we do that again?” and come up with no good reason why not. Such was the case with our August 1998 story that pitted tuner cars in a race to 150 mph and back to a stop—an unforgiving and indubitably entertaining test of horsepower and braking acumen. We billed the test as defining “a new performance standard for the coming millennium” and then never did it again. Hey, stuff comes up. In our defense, it is difficult to find real estate suitable for 150-mph exploits, and our 1998 venue—Chrysler’s Chelsea, Michigan, proving grounds, where we still test—wasn’t going to work for these particular hijinks. Back in the day, we used its 2.2-mile straightaway, but the only one we have access to now is 1.5 miles. That sounds like a lot until you’re doing 145 mph in a Honda Civic, staring at the speedometer creeping up digit by digit as you cover about two-thirds of a football field every second. To find a suitable stretch of asphalt, we had to secure our tray tables and taxi to Oscoda-Wurtsmith Airport, about three hours north of Detroit.If you’ve never heard of Oscoda, that’s probably because you’re not a Cold War bomber pilot or part of a current DHL or Kalitta Air cargo crew. Oscoda was once a base for nuclear-armed B-52s to set off on round-the-clock trips to the Arctic Circle—just in case the Soviets got rowdy—but now it’s mainly a cargo depot and maintenance destination. Oscoda also has a freshly paved 2.2-mile taxiway. Airport manager Jamie Downes advised that even though we’d be off the main runway, we shouldn’t wander too close to the Kalitta Air 747s running engine tests down beyond our starting line. “Did you see the MythBusters where they put cars behind a jet and throttled it up?” he asked. “They shot that here. The only vehicle that didn’t get blown away by the jet wash was a 57,000-pound plow.” We don’t have anything that weighs 57,000 pounds. Not even the Bentley Bentayga.Yes, our 150-mph roster includes SUVs, which would have been unthinkable last time. So would including a stock Civic, although we brought one of those—the Type R, of course—along with its Korean antagonist, the Hyundai Elantra N, but not a Toyota GR Corolla, as it maxes out at 144 mph. Representing attainable German speed, Volkswagen sent a Golf R, and representing half-attainable and half-German speed, Toyota furnished a GR Supra 3.0. That car seemed a natural foil to the Ford Mustang Dark Horse, our lone thundering American pony car (we asked for a Dodge Demon 170, but no luck). Beyond the Mustang, prices got mighty fancy, with the Cadillac CT5-V Blackwing dicing with the Bentley Continental GT Speed in a battle of large-format autobahn dominators. At the top of the food chain, Porsche fielded a 911 GT3 RS and a 911 Turbo S, and Chevy countered with a Corvette Z06.To break up the internal-combustion hegemony, the Kia EV6 GT flew the flag for electric vehicles everywhere. It wasn’t supposed to be the only EV, but the Tesla Model S Plaid we’d rented caught a nail in a tire the day we were heading to Oscoda, and we couldn’t get a replacement in time for testing. We did, however, run it later at our usual test venue since the straightaway there is long enough for a car that hits the required speed in a quarter-mile, and we ran a Lucid Air Sapphire on the straightaway at Virginia International Raceway. The results don’t count for the official scoreboard, but they were certainly enlightening [see “Heroic Electrics,” below].A note about our results: They’re more like lap times than our typical performance figures. We didn’t subtract the initial one-foot rollout or apply any correction for ambient conditions, and the results are simply the best run, not an average of passes in both directions or a merging of acceleration and braking segments from different runs. All of the foregoing, and the fact that Ocsoda’s fresh asphalt isn’t nearly as grippy as the concrete from our usual test venue, means that the 60-mph and quarter-mile times from this test aren’t comparable to other test results.As for our methodology, you might wonder how we attained precisely 150 mph before hitting the brakes. Answer: That was part of the challenge. Drivers had to eyeball the VBox display on the dash and attempt to max out at precisely 150 mph, which was easier in some cars than in others. At 145 mph, the 911 Turbo S was still scrolling numbers like Satan’s slot machine, while the less powerful cars aided precision.View PhotosThis image shows the field arranged in accurate relative finishing position, with the 911 Turbo S in front coming to a stop 1.1 miles sooner than the Civic Type R.Michael Simari|Car and DriverIn all but the slowest couple of vehicles, drivers would ideally initiate braking (as recorded by a trigger affixed to the pedal) at a hair under 150 mph. Then there is a fraction of a second as the pedal strokes down, hydraulic fluid pulses through the lines, calipers squeeze, and rotors begin transforming kinetic energy to heat. And that sliver of latency is the window for the car to clear the buck-fifty hurdle before initiating its brutal trip back to a stop. Judging that lag was its own black art, but if a driver actually saw 150 mph on the VBox display before braking—with the left foot in cars with an automatic transmission to save time—then that was probably too late. Some of the faster cars gained a half-mile per hour or more before the brakes took over. And, of course, if the Vmax speed was under 150 mph, the run did not count.Indeed, for a seemingly simple exercise, a lot can go awry. You can duff the launch, brake too early, or brake too late. Maybe the car gives a wiggle while hauling down and strays onto the dust at the edge of the lane. Perhaps you forget to turn off the air conditioning or fail to set the car in its most advantageous launch or aero mode. The preflight checklist differs from an Elantra N to a Z06 to a 911 Turbo S. But they all have one thing in common, both with one another and with those tuner cars from a quarter-century ago: Visiting 150 mph is always a thrill, even if you only stay there for a moment.The ContendersBase: $44,890As-Tested: $45,345315 hp • 3183 lb • 10.1 lb/hpread moreBase: $34,015As-Tested: $34,015276 hp • 3196 lb • 11.6 lb/hpread moreBase: $47,405As-Tested: $47,405315 hp • 3419 lb • 10.9 lb/hpread moreBase: $234,250As-Tested: $302,910542 hp • 5432 lb • 10.0 lb/hpread moreBase: $62,925As-Tested: $63,100576 hp • 4815 lb • 8.4 lb/hpread moreBase: $58,745As-Tested: $60,365382 hp • 3376 lb • 8.8 lb/hpread moreBase: $67,155As-Tested: $74,500500 hp • 4025 lb • 8.1 lb/hpread moreBase: $312,155As-Tested: $376,025650 hp • 5045 lb • 7.8 lb/hpread moreBase: $99,765As-Tested: $107,225668 hp • 4243 lb • 6.4 lb/hpread moreBase: $287,380As-Tested: $301,420518 hp • 3207 lb • 6.2 lb/hpread moreBase: $144,280As-Tested: $167,605670 hp • 3672 lb • 5.5 lb/hpread moreBase: $233,560As-Tested: $253,510640 hp • 3691 lb • 5.8 lb/hpread moreCar and Driver0–150–0 mph: 52.7 secondsFlat-earthers might change their beliefs after watching the Civic Type R complete its trip to 150 mph, which requires so much pavement—8389 feet of it—that the white Honda seemed to disappear over the horizon.

But Tesla-spec rubber is hard to come by, and the 1020-hp Model S couldn’t make it to Oscoda in time. Instead, we ran it the next week at our regular test venue. Because of the different track surfaces, we’re not including the Tesla in our official results. A further disappointment is that we couldn’t get a Plaid with the $20,000 Track package that offers upgraded wheels, tires, and carbon-ceramic brake rotors; our test car was on the base 19-inch Pirelli P Zero PZ4s.Since we were already adding asterisks, when we found ourselves at Virginia International Raceway with a 1234-hp Lucid Air Sapphire, we figured we might as well make a few 0-to-150-to-0 passes. Obviously, VIR introduces yet another incomparable surface, and its straightaways are far from test-track flat.Nevertheless, both megapowerful EVs ran more than three seconds quicker than the Porsche 911 Turbo S. As expected, the EVs’ advantage is in acceleration. The Plaid gets to 150 mph in 9.7 seconds and the Sapphire a second quicker still, putting them 3.8 and 4.7 seconds, respectively, ahead of the Porsche. That edge more than offsets their stopping distances, which were, thanks to their hefty curb weights, roughly 100 feet longer, hurting their overall times by less than a second. Very unofficially, the Sapphire’s time of 15.5 seconds beat the Plaid’s 16.2-second time. —Dave VanderWerpMoving the Goal PostBefore gasoline lost its lead, the 0-to-100-to-0 test was the benchmark of measuring a vehicle’s ability to accelerate and decelerate in one swift pass. In 1960, Aston Martin claimed the DB4GT did the deed in 24 seconds. Today it would likely be trampled by the average three-row SUV.In 1965, Carroll Shelby boasted that his 485-hp Cobra 427 could do it in 14.5 seconds. Engineer, Shelby test driver, and racer Ken Miles was said to have done it in 13.8. For its time, the accomplishment seemed unfathomable; however, analyzing our test numbers gives it some legs. When we tested the 2529-pound Cobra 427, it got to 60 mph in 4.3 seconds and arrived at 100 in 8.8. It covered the quarter-mile in 12.2 seconds at 118 mph—that’s quicker than a Mustang Dark Horse. But without anti-lock brakes, stopping the Cobra 427 would require a master’s in threshold braking.To compare the ’60s metal with modern machines, we ran the Porsche 911 Turbo S through the 0-to-100-to-0 wringer. It needed just 9.7 seconds to complete the task. The Cobra paved the way for a more strenuous test, which is why we added 50 mph in the 1990s. At 150 mph, overcoming aerodynamic drag requires 3.38 times as much horsepower as it does at 100, and the brakes must dissipate 2.25 times the energy. With today’s active aero, huge brakes, and massive horsepower numbers—and the fact that a Honda Civic can reach 150 mph—perhaps it’s time to add another 50 mph. —David BeardSenior EditorEzra Dyer is a Car and Driver senior editor and columnist.
