While the intake and charge-air pipes immediately attract attention due to their BRABUS Gold Heat Reflection sheathing, other important details of the conversion remain hidden from view. These include the two BRABUS special turbochargers with larger compressor unit, which produce a higher boost pressure than the production turbos.
The standard emission control system is replaced with an exhaust system featuring free-flow metal catalysts and down pipes with a diameter of 75 millimeters (3 in). In addition, a BRABUS stainless-steel sports exhaust system with actively controlled butterfly valve is available for all GLE 63 models. It gives drivers the option of choosing between a subtle "Coming Home" mode and a markedly sporty exhaust note at the touch of a button on the steering wheel.
The interplay of all high-performance components was perfectly coordinated with new mapping for ignition and injection by the BRABUS engine and electronics engineers using state-of-the-art test benches and test runs on public roads and racetracks. The result is an optimal blend of outstanding performance and impeccable stability.
As the model name BRABUS 700 indicates, the driver of the exclusive SUV Coupe has command over 515 kW / 700 HP (690 bhp) between 5,300 and 5,800 rpm. Just as impressive is the increase in peak torque to 960 Nm, which is on tap between 2,000 and 4,500 rpm.
The combination of the sheer power of the BRABUS 700 engine with the SPEEDSHIFT PLUS 7G-TRONIC transmission results in performance on the level of sports cars. From rest, the all-wheel-drive car accelerates to 100 km/h (62 mph) in just 4.0 seconds. The BRABUS Vmax unit included in the engine conversion bumps the top speed to 300 km/h (186 mph).
Anyone looking for even more performance can opt for the BRABUS 850 6.0 Biturbo 4x4 Coupe based on the Mercedes GLE 63 Coupe. Its twin-turbo V8 engine with an increased displacement of six liters produces a power output of 838 bhp and a peak torque of 1,450 Nm. This supercar accelerates from rest to 100 km/h in just 3.8 seconds and reaches an electronically limited top speed of 320 km/h.
At these speeds, the aerodynamic properties of the SUV weighing almost 2.4 tons also play an important role. For this reason, the BRABUS designers developed bodywork components for GLE 63 made from high-tech carbon, which do more than just emphasize the sporty look further.
