Mercedes-Benz adds SL 65 AMG

SL-Class flagship to debut at New York International Auto Show

Following introduction of its all-new SL in Detroit, in January, and a high-performance SL 63 AMG variant in Geneva, in March, Mercedes-Benz will debut the even-more-powerful SL 65 AMG at the New York auto show in April.

While the SL 63 AMG makes do with a mere 590-hp twin-turbo, 5.5-litre V-8 engine, the SL 65 AMG boasts a 630-hp twin-turbo, 6.0-litre V-12. And 738 lb-ft of torque!

About the only volume-production convertible you can buy with more power is the 650-hp Ford Shelby GT500 – and that’s a different type of car altogether.

Mercedes says the SL65 AMG will accelerate from 0-to-100 km/h in 4.0 seconds, a couple tenths quicker than its AMG sibling – as if the driver of either one is ever likely to engage in a drag race.

A mix of Grand Tourer and hard-core sports car, the SL 65 AMG features an AMG Speedshift Plus 7G-Tronic automatic transmission, an Eco start/stop function, and other measures to optimize its efficiency.

Aiding that effort, thanks primarily to its all-aluminum structure, the SL 65 AMG is 170 kg lighter than its predecessor.

The result is a fuel-consumption rating of 11.8 L/100 km (Euro cycle) – not economy-car levels but impressive considering its performance capability.

V-12 Biturbo badging on the side vents distinguish the flagship SL model from its lesser brethren.

The car is expected to be available this fall.
