2017 Mercedes-Benz S Class comes with new engines rivaling AMG image

Next year the flagship limousine will pack newly developed engines that rival with the AMG offerings, ahead of the expected mid life cycle refresh that should arrive next year as well.

Mercedes-Benz has decided to affix three new engines to the S Class lineup for the 2017 model year: inline-six diesel and petrol units, as well as a biturbo V8. The new units apparently have “ground-braking” technologies, such as an integrated starter-alternator (ISG), a 48-volt electrical system, and an electric auxiliary compressor (eZV). The new V8 comes in place of the older V8 in the S500 and should be “one of the most economical V8 petrol engines in the world,” according to the company. Codenamed M176, it has cylinder deactivation and comes with 476 horsepower (350 kilowatts) and 516 pound-feet (700 Newton meters) of torque from a biturbo 4.0-liter displacement. The S 500 will even get a petrol particulate filter as standard – Mercedes is a pioneer of the standard and makes use of a material called cordierite to build the filter.

The six-cylinder inline petrol engine codenamed M256 has an innovative 48-volt electric system and a turbocharger with electric auxiliary compressor, as well as an integrated starter-alternator. The ISG will deliver mild hybrid functionality, such as boost or energy recovery, as well as fuel savings previously reserved for high-voltage hybrid technology. The new 3.0-liter inline-six motor should come with more than 408 hp (300 kW) and more than 369 lb-ft (500 Nm) of torque. Additionally, the company also has the “most powerful passenger-car diesel engine in the history of Mercedes-Benz” – an inline-six diesel providing 313 hp – with a stepped-bowl combustion process, two-stage exhaust turbocharging and, for the first time, using variable valve timing.

    Now we know what that $85K+ price tag buys. SUPER TECH!! I just hope they build these engines to last as long as the one in my 1970 280se. 585000 miles and ticking them off daily.
