Mercedes is working on an all-new C-Class and details are starting to emerge about the next-generation C63.

According to Top Gear’s sources, the high-performance model will follow in the footsteps of the E63 and come equipped with a standard all-wheel drive system. That news might disappoint some fans, but the model will reportedly have a Drift Mode that decouples the front driveshafts for occasional rear-wheel drive fun.

Little else is known about the car, but it is expected to use a familiar twin-turbo 4.0-liter V8 engine. The current C63 has 469 hp (350 kW / 476 PS) and 479 lb-ft (649 Nm) of torque, while the C63 S packs 503 hp (375 kW / 510 PS) and 516 lb-ft (699 Nm) of torque.

In order to stay competitive with the BMW M3, the C63 is expected to receive a significant power boost. Detailed specifications aren’t available, but the publication says the next-generation C63 S could have 542 hp (404 kW / 550 PS). If that number pans out, the sedan could rocket from 0-62 mph (0-100 km/h) in the low three second range.

Those won’t be the only AMG variants either as there’s word of a C53. It is expected to borrow a hybrid powertrain from the E53 and CLS53. As a result, the model should have a turbocharged 3.0-liter six-cylinder engine with an EQ Boost electric motor that can deliver an additional 21 hp (16 kW / 21 PS) and 184 lb-ft (249 Nm) of torque. It remains unclear if the powertrain will be detuned for use in the C-Class, but it develops 429 hp (320 kW / 435 PS) and 384 lb-ft (520 Nm) of torque in the E53.
