Report: Mercedes-Benz SLS Replacement to be Called GT, Next E-Class Gets Four-Cylinder

The replacement for the Mercedes-Benz SLS AMG is under development, and it will not be called the Mercedes-Benz SLC AMG if a report from Autocar is to be believed. Instead, this Porsche 911-fighting sports car will be called the Mercedes-Benz GT when it debuts in mid-2014.

The 2015 Mercedes-Benz GT will be smaller than the outgoing SLS, with an aluminum spaceframe chassis and a body made of aluminum and composite panels. Power will reportedly come from a twin-turbocharged 4.0-liter V-8 with similar architecture as the 2.0-liter turbocharged four-cylinder in the Mercedes-Benz CLA45 AMG. This new engine will also make its way into the next Mercedes-Benz C63 AMG. Autocar says to expect output in the range of 500 horsepower, meaning that the GT would compete with the 520-horsepower Porsche 911 Turbo.

We spied a prototype of this SLS replacement testing at the Nürburgring earlier this year, and it appears to maintain the same long-hood, short rear deck proportions as the SLS but on a smaller scale. The gullwing doors from the SLS will not continue, though, as the Mercedes-Benz GT will adopt conventional doors for a broader consumer appeal. A coupe version will debut first, but there are rumors of a roadster version as well.

In other Mercedes-Benz news, Autocar is also reporting that the company is developing a lineup of new engines, starting with a straight-six that will result in new three- and four-cylinder units as part of a new modular powertrain architecture. These engines are expected to debut on the next-generation Mercedes-Benz E-Class which is likely to arrive in 2016. Reports surfaced about two years ago that Mercedes would reconsider straight-six mills for the next E-Class, an interesting decision given that the E-Class long ago abandoned gasoline inline-sixes in favor of V-6 engines.

Another rumor from Autocar concerning the next E-Class hints at a new technology called “Autobahn Pilot” which is described as an “autonomous driving assistant with an overtaking function.” This sounds to us like a more advanced version of adaptive cruise control that could also allow the car to pass slower traffic without driver input.

Keep an eye out for more news from Mercedes-Benz over the next few months about the upcoming 911-fighter and new engine technologies.

Another 911 competitor?  ROFLMAO!  I'm a PCA driving instructor and the one brand of car we NEVER have in our DE classes is a Mercedes Benz.  Maybe it's the brakes or the grip?  Our participants can run whatever they bring to the track, so in addition to hordes of Porsches we get Corvettes, M3s, Miatas, CTSs, Mustangs, Camaros,and an occasional Viper or Ferrari.  But never any SLs of any sort, and no AMGs.  If you're going to be a 911 competitor, or a Corvette or M3 competitor, etc., come to the track.  Oh, and will someone please let me know when Mercedes has 30,000 race track victories at every level, like Porsche?
