2012 Mercedes-Benz SLS AMG Roadster Long-Term Road Test


2013 Mercedes-Benz SLS AMG Roadster: Best V8 In The World

2013 Mercedes-Benz SLS AMG Roadster

There is no better normally aspirated V8 in production today than the 6.2-liter M159 V8 in our long-term 2013 Mercedes-Benz SLS AMG Roadster. Forget the LS7. Never mind the Coyote. Disregard the BMW S65. Even if they could match the sheer might of this engine — which they don't — none of them come even close to the depleted-uranium-warhead-in-an-alcantara-gauntlet-ness of the M159. It is in a class of one.

What's remarkable is that this is AMG's first-ever production engine family. It started as the M156 for duty in dang near everything with an AMG badge on it, and then received a few enhancements and a bigger number (M159) when plopped into the SLS. Okay, AMG knows their way around an engine, but their earlier work was essentially hot-rodding. It's not quite the same as designing from scratch.

In any case, the M159 makes piloting the SLS a freakin' blast and, frankly, has much to do with making the car special to drive. There's so much torque on tap, and the soundtrack is just intoxicating. I've said it before, I'll say it again: With this engine, the Germans have out-America'd America.
