700 HORSEPOWER for the new E 63
S edan or wagon: BRABUS PowerXtra B40 – 700 engine tuning makes the new
Mercedes E 63 S 4MATIC+ even more of a wolf in sheep’s clothing. The BRABUS
power unit engineers used state-of-the-art test bench technology and extensive
test drives on racetracks and public roads to develop a performance kit that
boosts the power output of the turbocharged 4.0-liter (243 cu in) V8 engine by
64.7 kW / 88 HP (87 bhp).
The plug-and-play auxiliary control unit upgrades the electronic engine control
unit with new mapping for injection and ignition, and increases the boost pressure.
As a result, the rated output jumps from standard 450 kW / 612 HP to
515 kW / 700 HP (603 to 691 bhp) at a low 6,100 rpm. Peak torque grows simultaneously
from 850 to 950 Nm (627 to 701 lb-ft), on tap already at 3,500
rpm. BRABUS recommends high-performance motor oil from technology partner
In harmonious concert with the nine-speed sports transmission, an E 63 S
4MATIC+ sedan with BRABUS PowerXtra B40 – 700 performance upgrade
accelerates from rest to 100 km/h (62 mph) in just 3.2 seconds. The slightly
heavier wagon takes just a tenth of a second longer for the same exercise. The
top speed of both body styles is 300 km/h (186 mph). Already under development
is a BRABUS Vmax unit, which will further increase the top speed.
Sound and performance are the strong suits of the BRABUS sport exhaust system
for all E 63 variants. The fully stainless exhaust lowers the back pressure and features
exhaust flaps for an electronically controlled sound management. From the
cockpit, the driver is able to choose between the discreet ‘Coming Home’ mode
and the open position of the exhaust flaps, which coaxes a particularly powerful
exhaust note from the twin-turbo V8.
