Mercedes-AMG Shows Off New 4.0 L Twin-turbo V8

Whether we’re talking about the exotic, gull-winged SLS super car or the heavyweight ML series SUV or the new-age muscle car C63, Mercedes’ AMG performance division has spent the better part of a decade stuffing ’em all chock-full of 6.3 liter naturally aspirated V8 goodness. With an expanding global market and increasingly stringent emissions regulations worldwide, however, the big V8 party couldn’t go on forever … and that’s OK, because AMG’s replacement is cleaner, more fuel efficient, and even more powerful than before!

Thanks to the magical awesomeness of turbocharging, the new AMG M178 engine can get more performance out of 4.0 liters than the old V8 could manage out of 6.3 (well- 6.2, anyway). The result is a 4 second 0-60 time and start-stop technology that allows the C63 to deliver 25 highway miles per gallon. That’s pretty good for a car making nearly 500 HP!

AMG has developed a high-output yet more compact engine for a new era of performance. The 469-hp 4.0-liter biturbo V-8 is more responsive yet up to 38% more fuel-efficient than its larger predecessor. Its massive torque reaches its 479 lb-ft peak at just 1,750 rpm, and holds it all the way to 4,500 rpm, for a 4.0-second 0-60 time and instant acceleration at any speed. Yet even with its advanced design and technologies, each AMG engine is still hand-built and signed by its own craftsman.

… or pony up the $65,000 required to sample the new C63 AMG sports sedan for yourself. Any way you slice it, though, try to remember that this year’s model is thirty eight percent cleaner than last year’s, goes faster, and costs about the same. How’s that for progress!?
