Test Driver Ratings & Comments
Acceleration commentsBoiling the tires is easy with this engine so managing wheelspin carefully is critical to a fast launch. Our fastest launch came with almost no wheelspin, feeding in the clutch at 3,500 rpm.
Braking ratingVery Good
Braking commentsQuick and effective engagement. Typical BMW feel — immediate effectiveness with consistent stopping performance.
Handling ratingVery Good
Handling commentsControl feel is virtually identical to 335i, but chassis is quicker responding and more nimble. Handling numbers are marginally better than 335i.
