The 2012 Mercedes-Benz SLK55 AMG will make its debut at the 2011 Frankfurt Motor Show in September, and it will be getting a revised look along with a new 5.5-litre V8 engine. This new V8 engine is similar to the new twin-turbocharged engine found in the new Mercedes-Benz CL63 AMG.

To slot the 2012 Mercedes-Benz SLK55 AMG below the SL and CL trims in the performance range, Mercedes-Benz had to remove the twin-turbochargers. But with a two-seater configuration, 2012 Mercedes-Benz SLK55 AMG makes up for its light body than its heavier brethren. No official announcement made on the specs of this V8 engine yet, but from looking at other Mercedes-Benz models, we know that this normal aspirated V8 engine produces about 410 horsepower and 398 lb-ft of torque. As for acceleration time from 0-60 mph, we’ll have to wait for Mercedes-Benz’s official press release.

Also features in the new 2012 Mercedes-Benz SLK55 AMG is the addition of stop-start technology along with AMG Cylinder Management technology to improve fuel economy. The AMG Cylinder Management technology works by cutting off to four cylinders in cruising conditions, but as soon as the accelerator is pressed hard, all eight cylinders are fired back on. And this process works seamlessly. Average fuel economy is estimated at around 7.0L/100km, while CO2 emissions will be 199g/km in European cycle.

Stay tuned, we’ll have more details when the 2012 Mercedes-Benz SLK55 AMG makes its official debut.
