November 5, 20169 yr AMG, the division known for building some of the maddest Mercedes-Benz performance models has something very special planned for their 50th anniversary next year. Autocar reports that AMG will be showing off a new performance sedan 'Vision' concept at an event. This concept will preview a production model possibly named GT 4 that is expected to debut in 2019. The GT 4 will be AMG's third dedicated production model – following the SLS and GT. It will target the likes of the Porsche Panamera and Bentley Continental Flying Spur. Codenamed 'X290', the GT 4 will differ from the GT as it will use a new modular platform from Mercedes-Benz, not a bespoke one found in the GT. However, various design cues of the GT will make its way to the new sedan. Power will come from a 4.0L BiTurbo V8 recently introduced in the E63. It will come in two states of tune and feature a tweaked version of the 4Matic all-wheel drive system. AMG is also considering whether or not the GT 4 should use a new integrated starter generator (ISG) that would not only give a quick boost of performance (around 20 horsepower), but also allow the vehicle to have a stop/start system to improve fuel economy.

November 5, 20169 yr This has been rumored for a while and makes no sense when the E63 when the E63 is built on a modular platform with a 4.0 V8 and will add 48 volt and ISG eventually. The AMG GT makes sense because they don't want to lose sales to 911s or GT-Rs or NSX, and the SL is a touring convertible with a big engine. I don't see them selling these GT sedans to anyone that wasn't already buying a Mercedes, unless the GT sedan is a 730 hp electric car. That makes more sense than another V8 sedan.
November 7, 20169 yr If I were AMG, I would go with Dual Electric motors and a Small solid generator to give it a long range. This engine would kick ass in a properly tuned AMG. AM Racing Engine 560 Lb Ft Torque 420 Hp That would give you 1,120 Lb Ft Torque with 840HP in an AWD Hybrid with generator to give a decent long distance drive.
