Just some notes on the figures:
The CG544 numbers are from a CG fact sheet which was issued early this week said to be from the SA road test. The fact sheet states car weighing 1630kg + driver and passenger yet the numbers 0-100 and 0-200kph are identical to the ones given in the other mag article which states weight as 1550kg - I suspect CG has got its data wrong and the 29.2s 0-300 CG544 is indeed the 1550kg car -this should be noted in the table, it is a light car !

Eclou's numbers and the Ruf 550 numbers were both with driver only so again needs to be noted since this can be worth up to 0.5s 100-200kph...

Eclou's 0-300kph was in hot conditions into a headwind so not really comparable with others but hopefully a 2nd gear start 100-250kph may be forthcoming with passanger which can be used as comparison...

As a matter of interest CG have done a 997tt for the tuner GP, carbon doors hood etc, seats weight down to 1482kg and the RS 624hp kit - now that will be interesting
