Test Driver Ratings & Comments

Acceleration commentsThe G35 Coupe's engine is one of the smothest I've experienced. It also offers an amazingly flat power band with plenty of low-end grunt. As a result we got our best acceleration times by simply stomping on the throttle with VDC off and then manually upshifting the automatic transmission.This launch technique produced minimal wheel spin but, again, the engine's strong low-end torque meant that it didn't require wheel spin to get the best times. Upshifts were very crisp, but when manually shifting the automatic it was necessary to bump the shifter forward slightly early to keep the engine from hitting the rev limiter.
Braking ratingNo Data
Braking commentsStopping distances increased durign each of our three braking runs (123 feet, 128 feet, 130 feet), suggesting that the brakes were fading. The pedal effort required to induce ABS was higher than it is on most new vehicles, but ABS clatter was about typical. The high pedal effort came after a small, initial "dead zone" of brake pedal movement that produced little, if any braking force. This gave the pedal more of an "on/off switch" feel than we'd like, and the effect seemed to increase during brake testing (which further suggested a brake fade issue).
