Doug DeMuro gives the 2026 Mercedes-AMG GT63 S E-Performance a strong 76/100 score, praising it as one of the fastest and best-driving four-door cars in existence with 830 horsepower, 0-60 in 2.4 seconds, and innovative cabin tech like dynamic buttons with individual screens that change based on function. The design successfully translates the coupe's aggressive aesthetic to a practical four-door form with muscular flared hips, and the sport seats deliver surprising comfort despite their serious racing-focused bolstering. However, the car's $200,000+ price tag (reaching $250,000 with options) represents poor value in DeMuro's view, and the laughably long model name undermines its emotional appeal compared to competitors like the M5 or RS6. This is a car for buyers who want maximum performance and luxury in a practical four-door package and have the budget to justify the premium pricing.
