After earlier on in the day we showed you the B63S-700 tuning for the ML 63 AMG, it's now time for its bigger brother in the Mercedes-Benz lineup to receive the same attention.
Brabus nutters took the 5.5-liter M157 AMG mill and completely modified or replaced all the engine's peripherals.
There are now two new Brabus turbochargers with larger compressor units, new intake and charge-air pipes with gold heat reflection insulation, a new free-flow exhaust system with a butterfly valve controllable from a button and a dedicated ECU control unit for the new arrangement.
The result consists of 700 hp and 960 Nm (708 lb ft) of torque that's been electronically-limited to protect the drivetrain. Unlike its smaller M-Class brother, who has a bit less weight and does the same feat in 4.4 seconds, the GL 63 AMG with the B63S-700 package can reach 100 km/h (62 mph) from a halt in 4.6 seconds. Top speed is the same electronically-limited 300 km/h (186 mph) though.
The exterior and interior design have also received Brabus' magic touch, with the Widestar bodykit somehow looking a little better on the GL than the ML, from our point of view. The interior is, as usual, a sumptuous leather fanatic's heaven, while the up-to 23-inch light-alloy wheels selection can be complemented with a Brabus control module for the Airmatic air supension.
