Actually, I think it was Car & Driver that ALSO got 5.6 seconds zero to sixty for the new 330i:
"...0 to 60 mph in 5.6 seconds and the standing quarter-mile in 14.3 seconds at 98 mph. Although these figures were recorded on a surface with poor grip, they match the performance of the current-generation 330i with Performance package with its much larger rear tires."

I think they are a fair match. Hopefully some mag will do a comparo between the two.
