2017 Mercedes S-Class To Get 4 New Engines — The Best Just Got Better

Other than the expected slight design tweaks and extra gadgets and tech inside, it would seem that this facelift is set to be a lot more than skin deep.

Mercedes unveiled a set of four new engines; three petrol and a diesel which will make their way under the extremely long bonnet of the new S-Class.

The first of the lot and the most powerful is a new twin-turbocharged V8 engine displacing 3982cc which is known internally at AMG as the M 276.

The AMG developed 4.0-litre V8 will replace the current 4.7-litre V8. The new engine cranks out over 470bhp and around 700Nm of torque.

The second new engine is a 3.0-litre inline 6-cylinder engine that displaces 2,999cc and is codenamed M 256 by Mercedes. The engine cranks out over 408bhp and 500Nm of torque.

The new inline six-cylinder engine is the first engine that Mercedes has designed for electrification from the outset and features a 48V mild hybrid system.

The hybrid system powers an Integrated Starter-Alternator (ISG) and the electric auxiliary compressor (eZV) which combine to negate any turbo lag.

The smallest of the petrol engines is a new turbocharged inline 4-cylinder codenamed M 264. The engine displaces 2.0-litres and is turbocharged and features the 48V mild-hybrid system. The engine has a specific output of 134bhp/litre.

The hybrid system powers a belt driven starter-alternator (BSA) that is responsible for for fuel-saving hybrid functions such as energy recovery and provides an engine speed boost at low revs.

The only new diesel is a turbocharged 3.0-litre inline 6-cylinder engine that is codenamed OM 656. The engine cranks out 309bhp and over 650Nm of torque.

The engine uses a stepped-bowl combustion process, two-stage exhaust turbocharging and, for the first time, ‘Camtronic' variable valve timing to help boost efficiency and power.
