Test Driver Ratings & Comments
Acceleration commentsElectric-only operation: Exceptionally quiet with just a little bit of motor whine, but mostly just wind noise. Very linear acceleration; obviously, no shifting. With gas engine assisting: Still linear, but you can definitely hear/feel the engine thrum.
Braking commentsConsistent stopping distances, negligible fade, firm pedal, but some rear end wiggle and wander. Pronounced dive.
Handling commentsSkid pad: Stability control non-defeatable. Very little if any brake corrections. Rather it just hits a wall of understeer. Steering is light and vague.
