Mercedes-Benz is set to introduce a whole range of new engines in 2017. There will be new 4, 6 and 8-cylinder motors available in turbopetrol and turbodiesel guises.

Starting with the smallest engine, the 2.0-litre 4-cylinder turbopetrol will have a specific output of 100 kW per litre. That means around 200 kW as a starting point. Mercedes is also adding a 48V electric system that can be used in hybrid format to boost engine speed by up to 2000 rpm, but also power ancillaries such as the starter motor and water pump.

The new 2.0-litre turbodiesel has already been launched and features in the smooth and comfortable E220d that we compared with the previous-generation 520d earlier this year. It puts out 143 kW and 400 Nm of torque.

Sticking with a turbodiesel, you can expect to see a new 6-cylinder version in next year’s S-Class. The new engine is 40 kW more powerful than the current engine meaning you get 230 kW and over 650 Nm of torque.

There’s a new 3.0-litre 6-cylinder petrol unit on the way as well. It’s an in-line 6, which is claimed to produce 300 kW and more than 500 Nm of torque. CO2 emissions are said to have been cut by 15% and like the 4-cylinder unit, it uses a 48V electric system to power the engine at low revs and also power certain ancillaries.

For those sold on a V8 then the all-new 4.0-litre motor appears to be even more powerful than the current 4.7-litre unit. Its power output has been lifted from the old engine’s 335 kW to 350 kW with 700 Nm of torque. That’s before any of the engineers at AMG have tinkered with it. The V8 features cylinder deactivation, effectively turning it into a 4-cylinder in certain situations to conserve fuel.

The larger engines – 4 and 6-cylinders will be available next year in the new S-Class with the others being staged in as various model updates are introduced.
