Some people might be satisfied that the 2014 Mercedes-Benz E63 AMG S-Model offers 577 hp and a top speed of 186 mph. Not Brabus. The German tuning house has turned its attention to the E63 AMG sedan and wagon, creating the wild Brabus 850 6.0 Biturbo.
To make more power, Brabus first bored and stroked the E63 AMG's 5.5-liter V-8 engine, pushing it to 5.9 liters of displacement. Along with new cylinder heads, a pair of larger turbochargers, a functional air intake in the hood, gold heat wrapping, and a new performance exhaust, that's enough for the Brabus 850 6.0 Biturbo to offer 838 hp and 848 lb-ft of torque. The company boasts that the engine actually could offer 1069 lb-ft, but that it has been detuned so as not to damage the seven-speed automatic transmission.
Rear-wheel-drive versions of the Brabus-fettled Mercedes-Benz E63 AMG take just 3.7 seconds to reach 62 mph, while the 4Matic all-wheel-drive models accomplish that feat in a mere 3.1 seconds. The standard E63 AMG S Model 4Matic takes 3.5 seconds to hit that benchmark. Depending on how customers order the car, the 850 6.0 Biturbo tops out between 186 mph and 217 mph. Fuel economy, Brabus claims, is the equivalent of 23 mpg combined in European testing.
Given the car's greatly increased performance, Brabus also saw fit to wind tunnel-test a new body kit designed to reduce lift at speed. Made from carbon fiber, the new kit comprises a prominent new front splitter, a subtle trunklid spoiler, and a new rear diffuser. The car also benefits from Brabus's own 20-inch Monoblock. On the inside, Brabus fits a custom leather interior that can be ordered in any color a customer desires, along with new shift paddles and aluminum pedals.
Brabus can either deliver an 850 6.0 Biturbo as a complete car, or convert a customer's existing Mercedes-Benz E63 AMG to the high-performance specification. Prices have not been released.
