Test Driver Ratings & Comments
Acceleration commentsV6 has decent power and gets a meaner rasp the higher it revs. Automatic shifts pretty quickly. Launching wasn't difficult, as the GS is not capable of wheelspin even with power braking. Best run came in Manual shift mode (by a tenth). Still shifts for itself at 6,400 rpm, but shifts seemed ever so slightly quicker in Manual. Manual shifting is via paddles or console lever (pull back for downshifts with lever). Blips throttle on downshifts.
Braking commentsFirm pedal, relatively short travel. Car tracks straight, but nosedive is noticeable and there's a significant (and surprising) amount of rear tire lockup. First stop was 115 feet. Shortest was 7th stop at 112 feet. Longest was 5th at 123 feet.
Handling commentsSkid pad: Light steering but at least some indication as to what the front tires were up to. Chassis isn't overly responsive to drop-throttle. But biggest problem was the throttle's sensitivity (or abruptness) in Sport Plus mode, which meant it wasn't as easy as it should've been to play with the throttle to adjust the car's attitude. Slalom: 69.7 mph is an impressive time for a car as big as the GS. Summer tires and the F Sport's stiffer suspension help. Platform feels solid and steering is quite quick. The electric assist isn't perfectly intuitive in its feel and weighting, but the F Sport goes where you point it and changes direction easily around the cones. Very planted and also reluctant to oversteer. ESC has high intervention point when on, gently reducing throttle and only adding brakes if you completely overdrive it.
