We have verified test data for 1 model year. Each year shows every recorded run, the publication that measured it, and the trim-level details.

Every figure is sourced from published road tests by Car and Driver. We don't use manufacturer claims — only independently timed runs — so the numbers reflect what the car actually does.

0–60 and quarter-mile results depend on driver technique, ambient temperature, tire condition, road surface, altitude, and testing instrumentation. A published figure is a single sample, not an absolute — which is why we show the range of verified runs rather than one number.
