Test Driver Ratings & Comments

Acceleration commentsOnce on boil, this blown V8 really responds. Shifts at redline keep the engine in the powerband so the Jag rewards hard driving.
Braking ratingVery Good
Braking commentsDecent pedal feel and short stopping distance are impressive for a 4,200-pound sedan.
Handling ratingVery Good
Handling commentsSkid pad: Good grip and better steady-state manners than other cars in its class. The Jag is even somewhat responsive to lift-throttle at the limit. Slalom: The XF requires manhandling to achieve this slalom speed. With lots of grip and lots of body roll, it takes a bit of hard driving to realize that the Jag's limits are actually quite high.
