Naturally aspirated 5.5-liter V8, 422 hp and 398 lb-ft of torque…this will be a dangerous toy! Advances have been made in fuel economy and CO2 emissions, too, the former improved by 30 percent in the new SLK 55 AMG over the old model. Combined economy is 33.2 mpg and CO2 emissions are 199 g/km. Stop-start system is as standard.
The engine also features an innovative F1-inspired AMG Cylinder Management shut-off system that allows the engine to run on just four cylinders under partial loads to help boost economy. More info coming soon…stay tuned.
