Test Driver Ratings & Comments
Acceleration commentsWith VSC off and Sport mode on, the first run in Drive happened to be the quickest of many more attempts that followed. That "best" launch was not able to be duplicated, nor were the blazingly quick manual shifts (which came later) able to make up the difference. I suspect I left 2/10ths on the table for the 0-60 time. Same 1.9-second launch plus mind-blowingly fast paddle shifts would certainly be a little quicker. Be that as it may, the IS-F doesn't roast the rear tires as instantly as, say, a 6.3 AMG engine does because the IS-F feels a little artificially torque-restrained from a standstill (brake diff?). Otherwise, power is linear up to the 3,700-rpm secondary intake threshold, where it goes mental. The sound and the fury of the V8 and exhaust system should be recorded for posterity.
Braking ratingExcellent
Braking commentsNot one bit of ABS noise or flutter, but the tires lurched against the pavement a couple times. Highly fade resistant as the distances tumbled with each additional stop. The pedal is extremely hard under full-ABS stops.
Handling ratingExcellent
Handling commentsWith VSC off and Sport mode on, the IS-F has gallbladder-flattening grip on the skid pad, but not much feel for what the front tires are enduring. Gentle understeer becomes a resolute "push" when prodded beyond its happy place. I really had to manhandle the car to coax smokey oversteer: It first resists with chattering understeer, then with the brake-actuated limited-slip differential, which finally gives up and allows lurid slides, drifting 1.5 times around the skid pad on full opposite lock. Unlike the stubborn understeer we experienced on the skid pad, the IS-F's tail gets pretty lively in the slalom, which ultimately is the limiting factor. Turn-in is amazingly good, with reassuring bite and grip that works up to a point when the tail begins to walk away gently. The Michelin PS2 tires are progressive and don't fall off abruptly when max grip is exceeded. Steering is still phoning it in rather than telling me in person.
