I don't know where to post this, but some acceleration numbers derived form sport auto with CLS/SLK and M5...


THE SLK 55 is a ROCKET, check out the in gear acceleration times generally up to about 100mph and then for 4th gear vs the other two 500bhp machines!

0 - 40 km/h: CLS55: 1.5 sec / SLK55: 1.5 sec / M5: 1.5 sec

Conclusion, disappointed with CLS 55 (if you can call a 55K engined car disappointing) , but SLK55 is amaaaazing, that 7 speeder is quicker intitally than both CLS and M5!! Imagine a more powerful AMG engine and 7 G tronic!
