Test Driver Ratings & Comments
Acceleration commentsEngine still feels good in this 4,000-plus-pound sedan. Must modulate wheelspin off the line. Loves to rev and...for the first time ever...the VQ-Series V6 actually sounds good from the outside.
Braking commentsImmediate, solid and consistent. Brakes are quite reassuring in this test.
Handling commentsSlalom: Better control in "standard" mode rather than Sport in this test. Almost too responsive in Sport mode. Hangs on in fast transitions better in standard mode. Skid pad: Perfectly happy to hang the tail out here. Easy to sense grip limits, even for a large sedan.
