The V12 is something that needs to be celebrated while we can, because the next generation of Lamborghinis and Ferraris might not have one. Brabus knows this and 15 years after showcasing the first G V12 at the 2004 Geneva Motor Show, the German tuner has once again packed a V12 under the hood of the G-Class.
This time, it’s the second generation G 63. The 4.0 V8 biturbo has been taken out for a massive, reworked 6.3-litre V12 biturbo. Special billet crankshaft with a longer stroke, larger cylinder bores, matching forged pistons and special precision-balanced billet connecting rods have resulted in a displacement increase from stock 6.0 to 6.3-liters.
In addition, the two production turbos are replaced by turbos with larger compressor unit and modified exhaust manifolds, which produce a higher boost pressure. The conversion includes 80 mm diameter downpipes, free-flow metal catalysts and a Brabus stainless high-performance exhaust system with active flaps.
There’s also a new intake manifold with larger cross-section and special filters, as well as Gold heat sheathing to lower the temperature. The reprogrammed engine electronics with special mapping for injection and ignition as well as modified boost pressure control round off the extensive rework. As a result, the 6.3 V12 biturbo develops 662 kW / 900 hp (888 bhp) at 5,500 rpm and a peak torque of 1,500 Nm (1,106 lb-ft) at 4,200 rpm. However, the torque is electronically limited to 1,200 Nm (885 lb-ft), most likely to show some mercy on the gearbox.
Speaking of which, a 9-speed automatic transmission sends power to all four wheels. Brabus claims a 0 – 100 km/h acceleration time of 3.8 seconds, while the top speed is electronically limited to 280 km/h (174 mph). There’s also a Brabus speedometer with 300-km/h (186-mph) scale.
Visually, the G V12 900 gets a similar treatment to that of the 800 Widestar, with generous usage of carbon fibre. The wide wheel arches add 10 cm to the width of the body and make space for massive forged wheels with diameters of 23 or 24 inches. The example showcased at the 2019 Frankfurt International Motor Show rides on 24-inch Brabus Monoblock Platinum Edition Z wheels, shod with 295/30 front and 355/25 rear tyres.
Brabus is building only 10 units of G V12 900, priced at €605,055 (excluding VAT, Germany).
