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.
