Despite the industry trend toward smaller engines, the German automaker will stand true to the car’s aggressive, big engine heritage. It did so by keeping the same 6.0-liter V12 engine passionately pounding under the hood with twin turbocharges spurring it on like a cocaine-fueled carriage driver.
Just because the 45-unit limited-production roadster runs the same engine as previous generations, you shouldn’t assume it went without improvement. AMG’s engineers managed to muster more horsepower, bringing the 2013 model up 17 hp for a total 621. The boys managed that by adding new manifolds, waste gate channels, and an optimized catalytic converter.
The current shift in engine productions seems to be to build smaller displacement engines that pump out larger amounts of horsepower, but trends aren’t meant to be followed by the likes of Mercedes-Benz. The new SL65 AMG has been revealed today, sporting a beefy V12 that makes 621hp.
Under the hood resides the same V12 as the last generation SL65 AMG, for the new model. However new manifolds, waste gate channels, and an optimized catalytic converter help boost the horsepower from the previous engine’s 604 hp to 621 hp. Mercedes used an all aluminium frame to help the car shed 254 lbs., not a small number when you consider the V12 makes a maximum 738 lb. ft. of torque. The weight loss and the power boost combine forces to propel the car from 0-60 mph in 3.9 seconds.
Another improvement to the new SL65 is the addition of the AMG SPEEDSHIFT PLUS 7-speed transmission. Previous to this generation, Mercedes-Benz did not have a a transmission that could handle the the torque of this type of engine, and the SL65 ran with a five speed auto.
The interior of the new SL65 AMG has all of the tech goodies that one would expect, including AIRSCARF neck-level heating, active lane keeping assist, LED daytime running lights, magic sky control roof, retractable hardtop roof, PARKTRONIC active park assist and tons of carbon fiber trim for the high level interior feel.
There is no price yet for the 2013 SL65 AMG, but we should find out more when the car debuts at the 2012 New York Auto Show in two weeks.
