FRANKFURT: MERCEDES SLK55 AMG
Big V8 plus teeny-tiny SLK equals yes please...
Despite having a more powerful motor the new SLK55 AMG is (comparatively) better for the environment than a BMW Z4 sDrive35i. The Merc emits 195g/km CO2, while the BMW squirts out 219g/km... Combined fuel economy is up to 33.6mpg (if you drive like an NEDC test driver), the BMW manages a 30.1. And it's slower.
Who cares about partial load though. Give the SLK55 the beans and you'll be rewarded with a dose more noise as flaps in the exhaust open up to release more of that V8 goodness. Will this be the first truly PH-worthy SLK? Perhaps the fact AMG has fitted it with a traditional auto, albeit seven-speed, rather than the faster-shifting MCT transmission from the facelifted C63 doesn't bode especially well.
