German tuning company Brabus has just revealed a new Mercedes-AMG C 63 S E PERFORMANCE upgrade. The biggest highlight? The PowerXtra B20E-730 upgrade.
Brabus PowerXtra B20E-730 Adds More Power
“730” refers to metric horsepower, equal to 720 mechanical horsepower. That’s 49 more horsepower than the standard factory model. The PowerXtra B20E-730 costs 8,211 euros or about 8,619 U.S. dollars at today’s exchange rate.
This upgrade is a piggyback control unit. It boosts the 2.0-liter turbocharged engine’s torque from 545 Nm to 645 Nm (or from 402 lb-ft to 476 lb-ft). However, it doesn’t change the electric motor or battery setup. That means the 204 ps (201 hp) electric motor and 320 Nm (236 lb-ft) torque stay the same.
No Higher Top Speed
Even with more power, the top speed stays the same. The Brabus 730 C 63 keeps the factory-set limit of 280 km/h (174 mph). For the wagon model (C 63 S E PERFORMANCE T-Modell), the top speed is 270 km/h (168 mph).
Faster Acceleration
What does change is acceleration. Brabus says the car can go from 0 to 100 km/h (0 to 62 mph) in just 3.2 seconds, compared to the factory’s 3.4 seconds.
Stylish Brabus Alloy Wheels and Lower Ride Height
Brabus also adds Monoblock Z PLATINUM EDITION alloy wheels. These 10-spoke wheels are 21 inches by 9.5 inches.
Sport lowering springs also lower the ride height by 5 to 20 mm (0.2 to 0.8 inches). These still work with the car’s adaptive damping system.
Upgraded Interior Details
Inside, Brabus includes some luxury touches:
- Aluminum pedal covers
- Velour floor mats
- Illuminated kick plates
Exterior Carbon Fiber Styling
Outside, there’s a lot of visible carbon fiber, starting with the front spoiler. It’s available in glossy or matte finish.
You also get more carbon fiber parts for the front bumper and grille, adding a more aggressive look. In the back, a carbon-fiber aerodynamic diffuser finishes the look, also in gloss or matte finish.
A Controversial Engine Choice
Even with all these upgrades, some fans feel the car still lacks something. Many believe Mercedes-AMG shouldn’t have replaced the twin-turbo V8 with an electrified 4-cylinder.
Even though this engine is a real AMG-built turbo, it feels more fitting in a smaller car like the A 45 rather than a C-Class.
Hope for a V8 Return?
There’s some good news. AMG is testing a CLE 63 model with a V8 engine. This could mean the C 63 might get its V8 back in a future update. A facelifted C-Class is expected in 2025 as a 2026 model.
