In June 2025, Mercedes-AMG whipped the wraps off the Concept AMG GT XX, a design study with which the German marque previewed a future high-performance four-door model…likely the next AMG GT 4-Door Coupé. Essentially the series-production version of the “pioneering” concept, the Affalterbach automaker has officially unveiled the new AMG GT 4-Door Coupé.

The AMG GT 4-Door Coupé was revealed in two guises: GT 55 and GT 63. Both models are equipped with three of the firm’s so-called axial flux motors, which produce combined system outputs of 600 kW/1 800 N.m in the GT 55 and 860 kW/2 000 N.m in the GT 63. Power is delivered to the road via an all-wheel drivetrain. In AMGFORCE S+ driver’s setting, the powertrain produces an augmented V8 soundtrack and features simulated gear shifts.

Mercedes-AMG says these figures allow the GT 55 to complete the 0-100 km/h sprint in 2.8 seconds, before breaching the 200 km/h marker 6.2 seconds later, at 9.0 seconds. The GT 63 dispatches the 0-100 km/h dash in a claimed 2.4 seconds, and the 0-200 km/h in 6.8 seconds. Both models top out at 300 km/h when specified with the Drivers Package.

For comparison, the previous GT 63 S 4-Door Coupé equipped with the firm’s (470 kW/900 N.m) 4.0-litre twin-turbocharged V8 completes the obligatory 0-100 km/h sprint in a claimed 3.2 seconds, while the (620 kW/1 470 N.m) GT 63 S E Performance plug-in hybrid (PHEV) reaches the 100 km/h marker from a standstill in a claimed 2.9 seconds.

The e-motors are fed by a Formula 1-derived 800 V battery, which provides an operating range of up to 700 km in the GT 55 and 696 km in the GT 63. Mercedes-AMG says a 10-80% DC fast charge takes only 11 minutes, with a 10-minute charge at such a facility adding 460 km of range.

Based on the carmaker’s AMG.EA platform, the AMG GT 4-Door Coupé measures 5 094 mm in length and 1 959 mm in width; making it 40 mm longer and 20 mm wider than its forebear. The wheelbase is longer, too – 3 040 vs 2 951 mm. The EV has a kerb weight of 2 460 kg – an increase of 413 kg over the ICE-only GT 63 S 4-Door Coupé. However, it weights slightly less (down 38 kg) than the GT 63 S E Performance PHEV.

5 Slowest-Accelerating Vehicles CAR Magazine Tested in 2025

Image
We have rounded up the five slowest-accelerating vehicles, based on their 0-100 km/h sprint times, tested by CAR magazine in 2025. See the list below. 5. Suzuki Swift 1.2 GLX MT: 12.05 seconds Image: Peet Mocke Starting the off the list is CAR magazine’s budget car of choice in our Top 12 Best Buys for 2025 awards, the Suzuki Swift. The variant we tested in March was equipped with a five-speed manual transmission. We recorded a 0-100 km/h acceleration time of 12.05 seconds. Although not the last word in straight-line performance, the Swift was one of the highest-scoring and most fuel-efficient vehicles we tested in 2025. 4. Honda Amaze 1.2 Trend MT: 12.22 seconds Image: Peet Mocke The Honda Amaze, which we tested in the July 2025 issue of CAR magazine, employs a 1.2-litre naturally aspirated four-cylinder petrol motor producing 66 kW and 110 N.m – the latter transferred to the front wheels via a five-speed manual gearbox. With a (tested) 32 kg weight penalty over the Swift...
