Porsche is making the Manthey Performance kit available for 911 GT3s in the United States.The kit improves performance through a variety of changes to the GT3’s aero bits, braking system, suspension, and overall weight of the car.The Manthey kit costs $57,300, but opting for the lightweight forged wheels adds another $15,500.Porsche is officially bringing a Manthey Performance kit to the Land o’ the Free for the first time. The kit has been available in Europe for the better part of a year, but us Yanks have unfortunately been left out—until now, that is. American owners of the 992-generation 911 GT3 can now buy the performance kit developed by Manthey. On its own, the 911 GT3 is no slouch. Porsche claims it circled the Nürburgring Nordschleife in a touch under seven minutes. A very fast time to be sure—though not quite as fast as the Manthey equipped GT3, which managed to shave 4.19 seconds from the lap, with a time of 6:55.737. PorscheThose extra seconds don’t come free—or even cheap for that matter. Purchase and installation of the kit will run owners a cool $57,300. A set of forged wheels, which reduce unsprung weight by approximately 16 pounds, is available for an additional $15,500 (nearly $1000 per pound). Hyper-specific track times and reduced weight are one thing, but what else does nearly $60,000 buy? A larger spoiler lip and side flaps are fitted to the front of the car. They pair with modified aero elements underneath and increase downforce at the front axle. The swan-neck wing at the back of the car also grows and now features a Gurney flap to keep the rear end firmly planted on the tarmac. PorscheWith the Manthey kit, the GT3’s rear diffuser also gets bigger and is now made of carbon-fiber-reinforced plastic. So are the “aerodiscs” on the rear wheels. The kit adds a four-way-adjustable coil-over suspension developed jointly between Porsche and Manthey. According to Porsche, the new setup increases spring rates by 10 percent on the front axle and 7 percent at the rear. The Manthey kit also adds braided steel brake lines, with the option to add racing brake pads as well. As with the normal GT3, Manthey models can be fitted with 20- or 21-inch forged wheels and can be had on Michelin Pilot Sport Cup 2 R tires. The kit is available now through Manthey certified Porsche dealerships. As of June 2023, potential customers or general enthusiasts will be able to check out the difference between the standard GT3 and the Manthey equipped car. For $1675, drivers will have the opportunity to compare the two versions at the Porsche Experience Centers in Atlanta or Los Angeles. This content is imported from poll.

The 1970 Dodge Challenger R/T SE “Black Ghost” sold for $975,000 at the Mecum sale in Indianapolis—$1,072,500 after fees.The Black Ghost has joined the National Historic Vehicle Association registry, along with the likes of the Ford Mustang from Bullitt.This special Mopar inspired one of the final editions of the current Dodge Challenger.The highly anticipated day has finally come for the legendary 1970 Dodge Challenger dubbed Black Ghost. This legendary Mopar car was street-raced in its day and flexed its Hemi around Detroit’s streets. Though, after being stored away by Godfrey Qualls, this potent Mopar became a sought-after myth among collectors and muscle car enthusiasts alike. Since its return to the public eye, this Challenger has been enshrined in the National Historic Vehicle Association, won awards at concours around the country, and, now, has a new owner.Dodge Challengers New and OldBefore his death, Godfrey Qualls passed along this piece of muscle-car history to his son, Gregory, who went on a mission to get this Challenger back on the road and share his father’s prized Mopar with the world. This oddly ordered Mopar became a hit at concourses and muscle-car enthusiast shows after its minor mechanical restoration, but now it’s time for a new life.For those out of the loop, the Black Ghost Challenger commands such lore because of how it was built, and what it did under Godfrey’s stewardship. Already rare, this 426-Hemi-powered Challenger is backed by a sought-after four-speed manual transmission. Ordered as an R/T SE, this Challenger was optioned with the luxury appointments you’d find with a special edition and the hi-po parts for the R/T. Topping off the mix, the gator-grain vinyl roof was a factory accident but adds to the car’s lore.After leaving the factory, Godfrey used the Challenger as you’d expect: he enjoyed it. This muscle machine did double duty as regular transportation and helped Godfrey haul his Norton motorcycles, while flexing its muscles on the Detroit streets.The heart of the Black Ghost is a 426-cubic-inch Hemi V-8.Photos Courtesy of Mecum Auctions, Inc.If you’re wondering if Gregory will miss the car, well, that’s obvious. “I will miss the car, but I realize I don’t need the car,” Gregory says. “At some point in time, when I first got the car out of the garage, I really needed the car. After losing my dad, you know—it was a thing for me to do to remember him. But then, as people started hearing the stories and I started learning things about the stories and about the car, I realized my dad’s always with me. I don’t necessarily need the car anymore—I can finally let it go. That’s where I’m at with it now.”While the Black Ghost might be moving underneath a new roof, the Qualls family will always be attached to the car. Gregory says, “The car will always be known, and my dad’s story will always be told. I think, for me, that’s the biggest honor of the things that could happen with this car story, is that the car story will live forever.”The latest chapter in this legend’s story happened at the Mecum Spring Classic, where it hammered for $975,000. It’s hard to predict the future, but we think this piece of history will be celebrated for a long time.Wesley Wren has spent his entire life around cars, whether it’s dressing up as his father’s 1954 Ford for Halloween as a child, repairing cars in college or collecting frustrating pieces of history—and most things in between.

After first revealing the Mercedes-AMG SL43 last year, the German brand has now decided to bring the four-cylinder variant of its grand tourer to the United States.The SL43 uses the same innovative setup as the AMG C43 sedan, with an electric motor integrated into the turbocharger, reducing lag.The 2023 Mercedes-AMG SL43 will cost $111,050 when it goes on sale this summer.The Mercedes-AMG SL43 debuted for Europe last year, sporting a 375-hp turbocharged four-cylinder engine with electrical assistance and technology borrowed from Formula 1 racing. At the time, Mercedes was still weighing whether it would bring the SL43 stateside, but now the German automaker has confirmed that the SL43 will reach the American market as a 2023 model, with sales set to kick off this summer. The SL43 serves as the entry-level model for the SL lineup, with four fewer cylinders under the hood than its V-8–powered SL55 and SL63 siblings. Although the SL43 can’t match the potent outputs of the V-8 models, the M139 inline-four—the same engine found in the CLA45 and GLA45 AMG—still churns out an impressive 354 pound-feet of torque to go along with the 375 ponies.Mercedes-BenzThe SL43 makes that power in an unusual way. The turbocharger strapped to the 2.0-liter engine includes an electric motor along with the usual exhaust-gas plumbing. The motor—a 1.6-inch-wide unit slotted onto the shaft between the turbine and compressor wheel—can spin the compressor wheel before the exhaust gases do. This promises to minimize turbo lag, and the e-motor can also maintain boost pressure under braking or when the car is coasting so the turbo is always ready to go when the driver gets back on the throttle. The Mercedes-AMG Formula 1 team uses the same technology in its turbocharged 1.6-liter V-6 hybrid race cars, and the C43 AMG sedan that debuted last spring features the same powertrain with an extra 27 horsepower.The 48-volt belt-driven starter-generator that powers the turbocharger’s e-motor can also provide an extra 13 hp in brief spurts. Mercedes says this jolt of power occurs at lower rpm and doesn’t increase the overall 375-hp peak output. The 48-volt tech also allows the start-stop system to work more smoothly and can regenerate energy under deceleration. Mercedes-BenzThe longitudinally mounted engine is paired with a nine-speed automatic transmission that uses AMG’s usual wet clutch pack instead of a torque converter. Mercedes claims the rear-wheel-drive SL43 will hit 60 mph in 4.8 seconds and will max out at an electronically limited 170 mph. The visual changes for the SL43 are minimal, with simpler styling for the front and rear bumpers and round tailpipes instead of the squared-off outlets on the eight-cylinder SLs. The standard wheels are 19 inches, but the SL43 can also be ordered with 20- or 21-inch wheels. The opulent cabin is unchanged for the entry-level model, and power-adjustable heated and cooled nappa leather seats come standard. The 2023 Mercedes-AMG SL43 will start at $111,050, undercutting the V-8 SL55 by nearly $30,000.More on MercedesThis content is imported from poll.
