Mercedes-AMG GT 63 S E Performance 2025 Review: 805 HP Thrill

The Mercedes-AMG GT 63 S E Performance stands as the pinnacle of AMG’s engineering, blending a thunderous twin-turbo V8 with cutting-edge electric assistance to create the brand’s quickest production car. Claiming a 0-62mph sprint in just 2.8 seconds, it outpaces even the hypercar-inspired AMG One, redefining what a four-door coupe can achieve in straight-line speed and high-speed stability.

Powertrain Innovation: V8 Heart with Electric Boost

At its core, this plug-in hybrid (PHEV) marvel pairs a hand-built 4.0-liter twin-turbo V8 producing around 603-639 horsepower and up to 900 Nm of torque with a rear-mounted electric motor adding 201-204 hp and 320 Nm. Combined system output reaches 805-843 hp and peaks at 1,200-1,400 Nm during a 10-second burst mode, propelling the 2,120-2,400 kg beast forward with ferocious intent.

The V8 revs eagerly from 2,500 rpm, delivering a glorious soundtrack that hybrid silence can’t fully mute. The electric motor integrates seamlessly via AMG’s 4Matic+ all-wheel drive and a nine-speed multi-clutch automatic, enabling rear-biased torque vectoring for drift-friendly antics in dedicated mode. On electric-only power, expect a modest 12 km range from the 6.1 kWh battery, prioritizing performance over efficiency.

Acceleration That Defies Physics

Independent tests confirm this GT’s explosive nature. MotorTrend clocked 0-60 mph in 2.4 seconds, quarter-mile in 10.4 seconds at 135.5 mph—nearly matching the Porsche 911 Turbo S. Car and Driver noted a quarter-mile in 10.4 seconds at 135 mph, with a second wind from the electric motor around 75 mph.

On the road, the launch feels like a heavyweight punch, hitting 100 km/h in under 3 seconds and 200 km/h in 9.5-10 seconds. High-speed runs on unrestricted autobahns reveal its natural habitat: rock-solid composure at three-figure speeds, piling on velocity effortlessly up to 199 mph.

Handling Dynamics: Straight-Line King, Twisties Challenger

Despite its mass, the GT 63 S E Performance shines in figure-eight tests, matching the 911 Turbo S at 22.5 seconds thanks to strong brakes, four-wheel steering, and predictable grip. The 50:50 weight distribution from the battery enhances balance, borrowing F1 tech for the electric system’s responsiveness.

Track performance dazzles on long straights, where V8 glory and hybrid torque dominate. However, tight circuits expose its heft—less agile than lighter rivals, better suited for grand prix-style layouts than twisty backroads. Drift mode makes tail-happy slides accessible without tire annihilation.

• Pros on Track: Blistering acceleration, stable high-speed cornering, effective brakes.
• Cons: Weight hampers agility in tight sections; not a dedicated track weapon.

Ride Quality and Daily Drivability

Mercedes tunes the adaptive suspension for grand touring supremacy. It glides over imperfections at speed, feeling relaxed and composed on motorways. Interior luxury matches the brief: premium materials, vast screens, and space for four, though rear headroom suffers in the coupe profile.

Steering offers good weighting at high speeds but lacks consistency in varied conditions. Ideal drive modes hide in submenus, requiring menu diving. Noise isolation is exemplary, with the V8’s 91-decibel roar a treat when unleashed.

Fuel Economy and PHEV Practicality

Official figures tout 7.7 L/100km combined, achievable with restraint and charging. Real-world use favors performance over parsimony—expect thirstier runs without plugging in. The 89 kg battery adds value through performance gains rather than revolutionizing efficiency.

Rivals and Market Positioning

Direct competitors are scarce. The upcoming BMW M5 hybrid promises similar V8-plus-electric thrills, while Porsche Taycan and Audi E-Tron GT go full-EV. At around $190,000-$214,500, it targets buyers craving V8 drama in a tech-laden package, outpacing non-hybrids like the prior GT63.

Interior Tech and Comfort

The cabin exudes opulence with hyperscreen options, ambient lighting, and Burmester audio. Front seats are supportive for high-g driving; rears accommodate adults for short jaunts. MBUX infotainment responds swiftly, though mode tweaks demand patience.

Verdict: A Grand Tourer with Supercar Pace

The GT 63 S E Performance excels as a high-speed cruiser and acceleration monster, blending hybrid efficiency with V8 soul. It’s not the nimblest on twisties, but for straight-line thrills and long-haul luxury, few match it. If raw fun means effortless speed over razor-sharp handling, this AMG delivers.
