"Perhaps the C on the mode dial stands not for Comfort but for Chiropractor," quipped one of the Daves. Like the BMW, the AMG is unyielding even in its most gentle suspension setting. ![]() It's the loudest of the group at 70 mph the only thing you can say about the excessive wind rush is that you're unlikely to notice it over the even more excessive tire noise. All of these cars have largish rear ends, but the GT63 would benefit most from some Spanx. At the start of this test, the blue jellybean was nobody's favorite. Verdict: A grand tourer that's plenty grand, just not when it comes to touring. ![]() Lows: Rigid, clomping ride passes the $200,000 mark. Highs: Steering, braking, and engine roar exactly like the sports car it's named after. Jessica Lynn Walker | Car and Driver 2nd Place: The BMW's passing times and 5-to-60 acceleration beat the others', too, and it tied with the Audi for best as-tested fuel economy. Its all-out acceleration times beat the RS7's and were a mere tick behind the GT63's, and its 147-foot stop from 70 mph and 291-foot stop from 100 led the pack. Judged solely by the testing equipment, the M8 wouldn't have finished last. Though that feature might matter only to us and the fine folks at Tire Rack who are probably filling an order for $778 worth of replacement 285/35ZR-20 Michelin Pilot Sport 4S rear tires right now. And yet we're going to call the M8 the dragster of the group, because while the Benz and BMW can disable their all-wheel-drive systems to become rear-drivers, only the M8 will do a "Big Daddy" Don Garlits–style burnout. While those numbers would do a supercar proud, the GT63 is even quicker. If this were a drag-racing competition, the M8, well, the M8 would still lose despite its ridiculously quick 2.7-second 60-mph time and 10.8-second quarter-mile. Verdict: An amazing car for escaping in a cloud of smoke, not so much for daily driving. Lows: The ability to find and amplify every road imperfection, steering that hates its job. Highs: Quick starts, quick stops, adolescently ferocious rear-wheel-drive setting. Jessica Lynn Walker | Car and Driver 3rd Place: While it would have fit the budget, power requirements, and lozenge shape of the segment, Porsche didn't want the Panamera on this fight card and wouldn't cough up a car. Living in that fantasy world and missing from this test is the 620-hp Porsche Panamera Turbo S. It hints at some alternate universe where everyone lives on an Alpine mountain and commutes to an office at the top of another peak and between them is the Nürburgring Nordschleife. That there are even three choices of racy, sweptback quasi-sedans is astounding. The RS7 is our underdog, with 591 horses, but it's also the least expensive: Our Tango Red test car arrived nearly fully loaded for $137,540. Comparatively, the M8 seems like a horsepower-per-dollar bargain at an as-tested $167,245 for 617 ponies. The GT63 tops the list in both power and cost, with 630 horsepower and-prepare the smelling salts-a $199,910 as-tested price. 2021 Mercedes-AMG E63 S Keeps Power, Adds Comfort.2021 BMW M5 Gets Updated Tech, Will Reach 189 MPH.Tested: 2021 Panamera Turbo S Flexes Its 620 HP.They're just a launch-control start away from proving it. All have the sleepy menace of a tough guy no longer at his leanest but still packing a mean right hook. The Audi RS7, the BMW M8 Competition Gran Coupe, and the Mercedes-AMG GT63 S are heavyweights in price and performance. "Swoopy, saggy-assed sedans" could work, but that doesn't quite capture the seriousness of this trio. Presumably to enrage our readers, the marketing people advertise these things as four-door coupes. Add up all three and you get 1838 horsepower. Each car has all-wheel drive, adaptive dampers, brake rotors the size of Saturn's rings, and a twin-turbo V-8 of at least 4.0 liters making completely unbuttoned dyno numbers. The brands started with the bones of a buttoned-down sedan and crafted a version with a narrow-eyed performance-car glare, a dropped roofline, and a sloping tail. In response to the question "How do you make a 600-hp sports sedan?" Audi, BMW, and Mercedes-AMG have turned in answers so similar that if this were an exam, they'd be accused of cheating.
