Mercedes-AMG will launch its new 2.Zero-liter turbo 4 in a handful of AMG 45-badged fashions within the very close to future and has recommended that it may get extra highly effective.
The M139, as it’s code-named, has already been formally confirmed with a peak output of 415 hp and 369 lb-ft (500 Nm) of torque. Energy per liter sits at a formidable 208 hp, making this essentially the most highly effective mass-production four-cylinder highway automotive engine ever.
In comparison with the M133 that powered the previous-gen AMG 45, the M139 has been flipped 180 levels, with the turbocharger and exhaust manifold now going through backwards. The turbo additionally options curler bearings and the engine incorporates an improved exhaust manifold serving to to forestall particular person cylinders from negatively influencing each other throughout load cycles, whereas it runs on 0W20 oil (!) and nonetheless wants servicing each 20,000 miles or yearly, no matter comes first.

If AMG does increase horsepower and torque figures from this engine, we may find yourself with some very thrilling efficiency automobiles. And to suppose blue-blood supercar of the early 2000s, like, theFFerrari 360 Modena, had “solely” 395 horses at its disposal (and fewer torque) – and, from what we recall, was ferociously quick.
