Recently, Mercedes-AMG announced its E Performance electric powertrain system, which will be first available on the next-generation AMG C-Class and AMG GT 4-Door models.
The AMG E Performance 400 V plug-in hybrid system consists of:
- 2.0 T or 4.0 T internal combustion engine
- 10.4 kW BSG
- AMG ONE-derived electric exhaust gas turbocharger
- 9-speed multi-clutch automatic transmission
- 6.1 kWh battery pack located above the rear axle
- Rear-axle electric drive system with two-speed gearbox and limited-slip differential
The 2.0 T engine is the M 139 found in the AMG 45 series, known as the world’s most powerful 4-cylinder engine. This engine will be longitudinally mounted for the first time in a high-performance C-Class model, and with the support of the electric exhaust gas turbocharger, the engine will output 449 horsepower (330 kW) and the system will provide a maximum output of 653 horsepower (480 kW) and 800 Nm of torque. The GT 4-Door, equipped with the 4.0 T engine, will output 816 horsepower (600 kW) and 1001 Nm of torque.
In the design and development of these new powertrains, AMG sought the help of the Mercedes-AMG Petronas F1 team based in Brixworth, UK. The cooperation includes electronic wastegate turbochargers and rear-axle electric drive systems. The latter can output 204 horsepower (150 kW) of power and 320 Nm of torque during short bursts of up to 10 seconds, with at least 95 horsepower (70 kW) available for everyday use. The 2 AT transmission system, similar to the Porsche Taycan, ensures acceleration performance throughout the entire speed range.
The 6.1 kWh three-element lithium-ion battery pack contains 14 L of insulating coolant. It is circulated through each battery module by a high-performance circulating pump and then enters a heat exchanger on the battery pack to transfer heat to a low-temperature circuit, ultimately dissipating into the atmosphere from the front of the vehicle. With a sophisticated cooling system, the battery pack is kept at a temperature of 45 degrees Celsius to optimize its charging and discharging performance.
Although the name GT 73 seems to have been confirmed, there is currently no news on whether the name C 63 will remain. However, AMG has also announced a purely electric platform, which is likely to be a high-performance version of the EQS.
