2015 Mercedes-Benz AMG GT

Rumors about the Mercedes AMG GT started awhile back and for a short period of time, it was believed that the new SLS AMG would be called the SLC. Obviously, this is not the case, but hopes for an AMG GT are still not lost as Mercedes will indeed offer the AMG GT after the SLS AMG makes its exit.

The AMG GT will actually be the baby brother of the SLS and will attack the likes of the Porsche 911 . Compared to the SLS, the future AMG GT will be lighter and slimmer with the use of plenty of carbon fiber and aluminum. In a shocking twist of SLS insult, the AMG GT will be devoid of gullwing doors.

The less dramatic specifications of the Mercedes AMG GT have also given way to a cheaper price tag compared to its brother. Expect to pay somewhere under €100,000 (about $145,000 at the current exchange rates).

Updated 07/18/2014: Mercedes unveiled a new teaser video, detailing the twin-turbo, V-8 engine found under AMG GT’s hood.

Update History

UPDATE 11/09/2011: British magazine, CAR, offers new details on the upcoming Mercedes SLC set to be released in 2015 - when the SLS goes out of production. The model will be offered in both coupe and roadster versions and, unlike previous rumors have stated, will only be offered with a 4.0-liter V-8 engine. The model will be built on the same aluminum-intensive engineering layout as the SLS, but it will feature a lighter curb weight, even better handling qualities and exceptional performance.

UPDATE 02/07/2012: Mercedes has finally green-lighted the upcoming SLC-Class, the company’s rival for the Porsche 911/991 . In an interview with AutoCar, AMG boss Ola Kallenius confirmed that the model will be offered in both coupe and roadster versions and will go on sale in 2013. Prices will start from £80,000 (about $125k at the current exchange rates). Expect it to be powered by a 500-horsepower twin-turbocharged 5.4-liter V-8 engine, not the previously rumored 4.0-liter engine. The SLC will sprint it up to a top speed of 180 mph.

Drivetrain


Mercedes has finally released a few of the nitty-gritty details surrounding the AMG GT’s new powerplant. Displacing 4.0 liters in a 90-degree, V-8 configuration, the aluminum block features a closed-deck design for added rigidity, while keeping its weight at only 461 pounds. The engine makes use of the innovated ‘Hot Vee’ configuration that routes the hot exhaust gases to the center Vee section, while the cool, fresh air is routed in from the outer sections of the cylinder heads. While it’s backwards from most conventional engines, it allows nearly instantiations pressure to the two turbochargers mounted within the Vee.

Forged aluminum pistons are fitted with ‘friction-optimized’ rings and the cylinder walls are covered with a NANOSLIDE coating for further friction reduction. A dry-sump oiling system keeps parts properly lubricated even while under extreme lateral acceleration, and eliminates the need for a large oil pan. Without the pan, the engine has been lowered in the chassis, decreasing the car’s overall center of gravity.

The four overhead cam shafts are fully variable in their timing work with Piezo direct fuel injectors to delivering a precise amount of fuel for varying circumstances. The two turbochargers’ temperatures are kept in check by an indirect intercooling system with a low-temperature water circuit. The result is cooler air entering the engine at higher pressure. That combination helps the 4.0-liter V-8 generates its 510 horsepower and 479 pound-feet of torque.

Competitors

Porsche 911 Turbo

Porsche 911 Turbo

Powered by the company’s familiar 3.8-liter, inline-six engine, the current Porsche 911 Turbo comes in two guises. The standard model benefits from 520 horsepower and 487 pound-feet of torque, which allow it to sprint from naught to 60 mph in 3.3 seconds and reach a top speed of 195 mph. Gearheads looking for even more power at the rear can opt for the Turbo S. The brawnier sports car churns 560 horsepower and 516 pound-feet of torque, meaning 0-to-60 mph times drop to only 3 seconds, while top speed receives a slight bump to 197 mph.

With the AMG GT still under wraps, it’s rather impossible to compare the two in terms of styling. However, we do know how the Merc looks on the inside and it appears the 911 and the AMG GT are figthing on equal grounds. The Porsche 911 Turbo retails from $151,100, while the Turbo S fetches at least 182,700.

Audi R8 V10

Audi R8 V10

Unlike the 911 Turbo and the AMG GT, the Audi R8 V10 Spyder gets it juice from a larger, 5.2-liter V-10 engine. But although it’s bigger and has more cylinders than its counterparts, the Audi Audi unit crank "only" 525 horsepower and 391 pound-feet of torque, placing the R8 below the Porsche 911 Turbo S. When paired with a seven-speed S-tronic transmission, the V-10 mill pushes the sports car from 0 to 60 mph in about 3.7 seconds, while the manual gearbox slows it down to about 4 seconds.

As far as top speed is concerned, the former reaches 193 mph, while the latter touches its limit at 194 mph. The R8’s interior might not seem as rich when compared to both the 911 Turbo and the AMG GT, but it comes with plenty of luxury and convenience features and a long list of options. Pricing for the Audi R8 V10 begins at $164,000.

Press Release

A new AMG high-performance automobile is all set for its world premiere in the autumn of 2014. The Mercedes-AMG GT will thrill sports car fans throughout the world with breath-taking design and supreme agility. Fascinating, dynamic - and versatile into the bargain: the GT is destined for a new segment - turning the dream of the authentic Mercedes-AMG sports car into reality.

"The new Mercedes-AMG GT shows that we will be positioning AMG more vehemently and aggressively than to date as a dynamic sports car brand," notes Tobias Moers, CEO of Mercedes-AMG GmbH. "The technological substance of the Mercedes-AMG GT underscores our high aspirations with regard to driving dynamics, agility and sportiness. Following the global success of the SLS AMG, the new GT is the second sports car developed fully independently by Mercedes-AMG. An initial exclusive look at the design of the interior shows what is in store for our customers: a GT sports car in its purest form."

The sensual purity of a superlative driving machine

A sneak preview of the interior provides an alluring foretaste of the new Mercedes-AMG GT: the interior design embodies emotion and sensuality like no other sports car. The uncompromising lines of the interior components and their authentic materials exude a clarity that uses contrasting effects to help define the concept of "modern luxury".

A dominant aspect in the cockpit of the GT is the further stylistic development of the central "aviation design" theme which is typical of Mercedes-Benz sports cars. The dashboard places an extreme emphasis on width, creating an impression of a powerful wing. This effect is supported by the four central spotlight-style vents and the individual vents at the left and right ends of the dashboard. The dominant centre console presents a correspondingly dynamic character: its shaping reminiscent of a NACA air intake and the employed materials suggest that it has been adopted directly from motor racing. Another clever design feature comes in the form of the controls on the AMG DRIVE UNIT, which are arranged like eight cylinders in a V layout, further bolstering the powerful and high-tech impression made by the centre console.

Enough to set pulses racing even when stationary

The interior of the Mercedes-AMG GT also boasts a fascinatingly exclusive look and feel, with the finest materials and outstanding workmanship combining to conjure up a setting that simply exudes class. As such, the exclusive interior of the Mercedes-AMG GT is enough to get one truly hooked on this vehicle even while it is still at a standstill. Designed to set the driver’s and front passenger’s pulses racing even before the car moves off, it provides an enticing intimation of the superlative dynamic performance that can be expected of the new GT when its AMG V8 is brought to life.
