Brabus tunes Mercedes-AMG GT up to 600 horsepower

"You can never have enough power," says Brabus in the statement below, "especially in a sports car." Hence the beast you see here. It's based, as you can plainly see, on the Mercedes-AMG GT. But instead of 469 horsepower in the base model or 503 in S spec, Brabus has boosted it up to 600 metric horsepower. That works out to 591 hp by our standards, a figure backed up by an equally impressive 553 pound-feet of torque – up from 443 or 479. With all that power and twist, the Benz tuner of record says its take on the GT will top out at an autobahn-crunching 201 miles per hour, reaching 62 along the way in 3.6 seconds. Of course, Brabus didn't just tinker with the engine and leave the rest alone. It'll build customer vehicles to individual requirements, but has outfitted this demo vehicle with a full aero kit (in clear carbon fiber), monoblock alloys (20 inches up front, 21 at the back), a retuned suspension dropped by 0.6 inches, and a fully refitted interior. We'll be keeping an eye out for the Brabus GT at the Frankfurt Motor Show this week, but judging from the photos above, it would be hard to miss.

At the IAA 2015 in Frankfurt am Main, the exclusive sports program for the Mercedes-AMG GT and GT S models celebrates its world premiere. With an output increase to 441 kW / 600 HP (591 bhp) and a peak torque of 750 Nm (553 lb-ft), the two-seat car reaches a top speed of 325 km/h (201 mph). From the outside, the sports car with BRABUS design impresses with aerodynamic-enhancement components made from clear-coated carbon, ultra-light BRABUS Monoblock F forged wheels, a sports suspension with a multitude of selectable settings for damping and ride height, and a sports exhaust system made from especially lightweight titanium with electronically controlled sound management. BRABUS fine leather interiors and inlays made from real carbon and precious wood upgrade the cockpit of the two-door car. You can never have enough power, especially in a sports car.

2015 Mercedes-Benz ML400 Quick Spin

Mercedes-Benz has taken a risk in its quest to downsize its engine range. For 2015, the brand's popular M-Class five-passenger CUV did away with its trusty 4.4-liter, twin-turbocharged V8, and has replaced it with a 3.0-liter, twin-turbocharged V6. It's no surprise that power is down thanks to this move. Outputs of 402 horsepower and 443 pound-feet of torque are replaced by 329 hp and 354 lb-ft, but weight is down significantly as well. The new ML400 is nearly 300 pounds lighter than the 4,982-pound ML550. Will that tradeoff be enough to satisfy a buying public that's embraced falling fuel prices by buying bigger and thirstier vehicles? To find out if the blown V6 is a suitable replacement for the twin-turbo V8, we spent a week at the helm of the all-new ML400. Driving Notes This 3.0-liter, twin-turbocharged V6 is the same engine being offered in the C400 and E400 sedans. Typical of today's turbocharged engines, peak torque is spread lavishly across the rev range, from 1,600 to 4,000 rpm. That's not as generous a spread as the ML550, which offers all its torque between 1,600 and 4,750, but the power on offer is easy to access. Importantly, the new V6 never feels flat-footed or unable to answer our commands. In fact, the ML400 feels even quicker than its six-second sprint to 60 would indicate, although it's not so fast as to challenge the 5.3-second time of the ML550. After a slight and expected bout of turbo lag, the power arrives suddenly and proceeds linearly until just south of the engine's 6,500-rpm redline. The throttle response is soft in Eco mode, as expected, but sharpens up slightly when the fuel-sipping mode is off, where the gas pedal is still easy to modulate. It's a quiet engine, too. Compared to the brawnier exhaust note of the old ML550 or the howling six-cylinder in the BMW X5 xDrive35i, the ML400's note is smooth and refined, befitting of a V6. Its turbocharged nature is instantly noticed, though. Get on the throttle and the 3.0-liter happily hisses its way up the tachometer. But, it's only when you get on the throttle hard that the engine really weighs in. In day-to-day driving and traffic its soundtrack is unobtrusive and relaxed. The EPA rates the ML400's fuel economy at 18-miles-per-gallon city and a 22-mpg on the highway. That's better than the 14 city and 19 highway of the old V8 ML, but it still seems a bit low, especially for the highway figure.

Ford Mustang Shelby GT350R named Road & Track Performance Car of the Year

With a 526-horsepower, 5.2-liter V8 that roars to 8,250 rpm, it's really hard to consider the 2016 Ford Shelby Mustang GT350R an underdog in any fight. However, the Shelby held the lowest as-tested price and was only middle of the pack in terms of power in Road & Track's 2016 Performance Car of the Year challenge. The 'Stang's numbers clearly didn't tell the whole story about the potent coupe because Ford's muscle car grabbed the title in this year's test. A model needs to be new or significantly updated to be eligible for the honor, and R&T found an impressive slate of eight candidates this year. The challengers included the Bentley Continental GT3-R, Cadillac ATS-V Coupe, Chevrolet Corvette Z06, Dodge Viper ACR, Mercedes-AMG GT S, and Porsche Cayman GT4. The Ferrari 488 GTB was the most expensive of the bunch with an as-tested price of $347,942, which is five times more than the Shelby. Once the group was together, R&T hustled them over curving roads and on the National Corvette Museum Motorsports Park. There was a lot to love about the Shelby, even in this impressive crew. "With a flat-plane crank and Sport Cup 2 tires, the GT350R is a Mustang turned up to 11," editor-in-chief Larry Webster said in the announcement of the results. The GT350R joins some great company. Past winners include the Porsche 911 GT3 last year and the Corvette in 2013.
