Just an update : This Sport Coupe is not based on the new W204-series C-Class chassis, though: it's basically an update of the existing car. It will receive general updates to suspension, steering and so on, plus the continuing 156bhp supercharged C180, C200 (184bhp) and C230 (204bhp) petrol engines, and 136bhp C200 CDI and 170bhp C220 CDI diesels. The C280 V6 (231bhp) may be a new option, however.
