GL HERO SHIMA Posted April 21, 2024 Posted April 21, 2024 Mercedes-AMG has revealed a hybrid version of the GT coupe, which produces 805 horsepower and 1047 pound-feet of torque. The 2025 Mercedes-AMG GT63 S E Performance pairs a twin-turbo V-8 with a rear-mounted electric motor. Mercedes claims a zero-to-60-mph sprint of 2.7 seconds and a top speed of 199 mph. Mercedes-AMG decided that the GT63 coupe's 577 horsepower wasn't enough. Meet the new range-topping 2025 Mercedes-AMG GT63 S E Performance, which emits a beastly 805 hp from its hybrid V-8 powertrain. Revealed in Shanghai during the Formula 1 race weekend, the new E Performance model has a hybrid setup that takes inspiration from proven technology used in the world's top open-wheel race cars. This same powertrain already appeared in the mechanically related SL63 convertible. Hi-Po Hybrid The E Performance system pairs a 603-hp twin-turbocharged 4.0-liter V-8 with a rear-mounted electric motor. The permanently excited synchronous e-motor produces 201 hp, which it sends to the wheels through a two-speed transmission and limited-slip differential. The e-motor can also send its power to the front wheels if necessary for extra traction. Along with 805 ponies, the hybrid system pumps out a total of 1047 pound-feet of torque. Feeding the e-motor is a lightweight 6.1-kWh AMG-specific battery that lives above the rear axle and has a direct cooling system that sends a special fluid around each of the 560 cells to maintain a consistent temperature and improve battery performance. Mercedes claims the coolant they developed can store more thermal energy than water-based systems and has a heat capacity two to three times higher. Mercedes also says the battery tech is informed by the hybrid system in the company's Formula 1 race cars and focuses on fast power delivery and draw instead of prioritizing range. The pack is recharged with a 3.7-kW on-board AC charger. Mercedes claims the E Performance will blast to 60 mph in 2.7 seconds en route to a 199 mph top speed. That's three-tenths quicker to 60 mph than the company's claim for the standard GT63. There are eight different drive modes, including an all-electric setting, Sport, Sport+, and Race. The hybrid AMG also gets four levels of regeneration for the battery, including a mode that's akin to one-pedal driving in an EV. https://www.caranddriver.com/news/a60551603/2025-mercedes-amg-gt63-s-e-performance-details/
