The 2023 Mercedes-AMG S63 returns as a plug-in hybrid with 791 HP

The 2023 Mercedes-AMG S63 E Performance makes 1,055 pound-feet of torque with its combination of a twin-turbo 4.0-liter V-8 and a rear-mounted electric motor.

So is the 2023 Mercedes-AMG S63. Mercedes controversially replaced the V-8 in the AMG C63 with a four-cylinder plug-in-hybrid setup, raising concerns among AMG aficionados that other high-powered Mercedes could suffer. a similar degradation. But fear not, because the new 2023 Mercedes-AMG S63 E Performance retains its twin-turbocharged 4.0-liter V-8, adding a permanently excited synchronous electric motor to produce 791 hp and 1055 pound-feet of torque.

All that power shoots the mammoth sedan to 60 mph in 3.2 seconds and then to an electronically limited top speed of 180 mph. The V-8 engine produces 603 hp and 664 pound-feet on its own, fed through a nine-speed automatic transmission. The hot V configuration, with the turbochargers tucked between the cylinder banks, is intended to improve responsiveness. The V-8 also features a belt-driven starter generator that is integrated into the 400-volt electrical system.

The electric motor, meanwhile, is mounted on the rear axle and is paired with a two-speed transmission and an electronically controlled limited-slip rear differential. Second gear engages around 87 mph, when the electric motor reaches its top speed of 13,500 rpm, bringing the engine back down to low rpm, where it hits its peak torque. The electric motor can generate 188 hp for up to 10 seconds, or 94 hp continuously. While the gasoline and electric powertrains use separate transmissions, the four-wheel drive system allows power from the electric motor to be sent to the front wheels as well so the S63 can function as an all-wheel drive electric vehicle. wheel. wheel.

The battery pack is located above the rear axle and has a capacity of 13.1 kWh, providing a driving range of approximately 20 miles. Mercedes says the rear-axle placement of the motor and battery improves weight distribution and handling.

The S63 offers four levels of regeneration: the lowest allows for coastal driving, while the highest allows for single-pedal driving and can put up to 90kW back to the battery. Battery charging is handled by a 3.7 kW onboard AC charger, but Mercedes didn’t mention an estimated recharge time.

The new S63 comes with seven driving modes. The car starts quietly in electric mode, though a “signature AMG” starting sound plays on the interior speakers, and the S63 uses exclusively electric power up to 87 mph. The AMG also plays low-frequency sound on exterior speakers up to 19 mph to alert pedestrians of the luxury barge’s presence. As the battery charge is depleted, the car switches to Comfort, which balances the two powertrains for a smooth drive. A battery retention setting maintains the remaining charge, while Sport and Sport+ prioritize electric motor power for spirited driving. A Slippery setting flattens the torque curve and prevents electric-only driving, while Individual allows the driver to customize the setting.
