Mercedes just unveiled the facelifted E-Class, but additional changes could be in the works for the bread and butter model.

Motor Trend is reporting the E550's (aka E500) twin-turbo 4.6-liter V8 engine could be replaced by a new twin-turbo 3.0-liter V6. As the saying goes "there's no replacement for displacement" and this appears to be case as the magazine is reporting the engine will produce roughly 330 bhp (246 kW) and 350 lb-ft (474 Nm) of torque. For comparison, the V8 churns out 402 bhp (300 kW) and 443 lb-ft (600 Nm) of torque.

It remains unclear if the twin-turbo 4.6-liter V8 engine will still be offered in the sedan - at least in the United States - but the magazine doesn't sound overly optimistic. Despite this, there is the possibility that the engine could still be available in the E-Class Coupe and Convertible.
