0–60 mph figures are Mercedes-Benz-claimed unless marked † (instrumented magazine test). "—" means we could not confirm the figure from a source. MSRP is US base price at launch, excluding destination. Many Mercedes models are electronically limited (often 130 or 155 mph, higher with AMG Driver's Package); see trim notes.
