2015 Mercedes SL400 Revealed With Twin-Turbo V6

2015 Mercedes SL400 Revealed With Twin-Turbo V6

The Mercedes-Benz SL400 has made an appearance, sporting a twin-turbo V6 powerplant.

Essentially replacing the SL350 in the convertible’s lineup, the SL400 boasts the same 328 hp and 354 lb-ft of torque as the E400, since it shares the same 3.0-liter V6 engine. Compared to the naturally aspirated 3.5-liter V6 in the SL350, the SL400 will boast 26 hp and 81 lb-ft of torque more than the model it’s replacing.

Don’t expect to find the German automaker’s nine-speed transmission mated to the powerplant however, as Mercedes has opted to pair the V6 with its seven-speed transmission. The SL400 will accelerate to 62 mph from a standstill in 5.2 seconds, besting the SL350 by 0.7 second.

Historically the SL350 model was not offered in North America, with the SL550 being the entry-level option. That said, it’s not clear if the increased performance of this new SL400 will make it a viable option for the U.S. market.

    I ordered one of the first ML400s to be made. Building it in Germany in August, and hoping for a mid-September delivery to San Jose, CA. Bought about $10K in options, but will report about the new V6 to you all at a later date.

    tell me road handling once you got. Can it beat the SLK 55AMG handling? I doubt so?
