Mercedes-Benz E 63 AMG Now Features 5.5L V8 biturbo at 22% Less Fuel Use

In brief: The Mercedes-Benz 5.5L V8 biturbo engine was introduced last year in the CLS 63 AMG and now is in the upcoming E 63 AMG, lowering fuel consumption by 22%.

The word

The M 157 5.5L V8 biturbo in the new E 63 AMG delivers 557hp and reduces fuel consumption by 22% (to 25mpg US, NEDC combined). It will replace the current AMG 6.3L V8 naturally aspirated engine.

The car will also feature Mercedes' new electromechanical steering, which is both speed-sensitive (for stability) and only draws power when actual wheel turning is taking place, otherwise not burdening the engine.

The M157 engine is coupled to a 7-speed sports transmission using AMG SPEEDSHIFT MCT. The car also features a stop-start in Controlled Efficiency transmission mode and can be deactivated by the driver through the console.

In ECO mode, the car runs with stop-start and with earlier gear shifting, avoiding high engine speeds (and thus fuel usage) while increasing the fuel optimization through demand-driven injection and generator management. Regenerative braking is also built into the E 63 AMG.

And so ...

Very cool to see these high-end cars getting all of these eco-treatments.
