The entry-level SL-Class in the U.S. is the V-8-powered SL550, but overseas Mercedes-Benz offers a six-cylinder model, the SL350, which is powered by a 3.5-liter V-6 and even comes with eco-friendly Blue Efficiency trim in certain markets.

The SL350 is now being replaced by a new SL400, and this one gets a twin-turbocharged 3.0-liter V-6 engine good for 333 horsepower and 354 pound-feet of torque.

In the SL400, the engine delivers 27 more horses and 81 more lb-ft than the naturally aspirated V-6 it replaces. And it’s more efficient, too. Mercedes says the SL400 is good for 0-62 mph acceleration in a brief 5.2 seconds, and gas mileage for the European combined cycle is quoted at 32.2 mpg.

Note, this is the same engine appearing in the 2015 C400 in the U.S. later this year, and it will also be offered in other Mercedes models such as a 2015 E400. However, we’re not expecting the SL400 to be sold locally.
