Having recently put the Mercedes-Benz E63 AMG S through its paces, the CAR team was duly impressed with the super saloon’s 430 KW and 800 N.m. But what if those lofty outputs could be increased by 45 and 80 per cent respectively? The result would be unfathomable – but not in German tuner Brabus’s book.
At this week’s Essen Show, the tuning firm showcased an über Estate version of an E63 AMG. Dubbed the Brabus 850 6.0 Biturbo, which is of course also available as a saloon, its engine displacement has been increased from 5,5 to 5,9 litres. The motor’s innards are upgraded with custom forged pistons, a precision-balanced billet crankshaft and eight custom billet piston rods, while a pair of bespoke turbochargers with enlarged compressors and specially-made manifolds are bolted on.
That, allied with an all-new engine management system intake and charge-air tubes with special “gold heat reflection” sheathing, helps the 850 6.0 Biturbo to produce 625 kW and 1 450 N.m, although the latter will be electronically-limited to 1 150 N.m for the sake of “maintaining the longevity of the engine”.
The upgrade kit is compatible with both rear-wheel drive and 4Matic versions of the E63 AMG and enables the car to reach 100 km/h from standstill in 3,1 seconds (quoted for the AWD version) and to a limited top speed of 300 km/h. But if you opt for high-performance tyres the saloon will allegedly hit 350 km/h.
Brabus offers tailor-made tyre/wheel combinations for the 850 6.0 Biturbo. The largest version is one-piece Monoblock F or R wheels in size 9,5Jx20 with 255/30 ZR20 tyres at the front and 295/25 ZR20 at the back. There is also a version that features Monobock R “Platinum Edition” forged wheels in sizes 9Jx20 in front and 10,5Jx20 at the rear, the company says.
To complete the package, Brabus has fashioned carbon fibre body panels with the help of wind-tunnel testing. The front spoiler lip, which attaches to the stock bumper of the E63 (and also fits the saloon), is claimed to reduce negative lift on the front axle at high speeds while the diffuser insert provides a purposeful backdrop for the two dual sports exhaust tailpipes.
The interior is clad in Mastik leather and Alcantara in any desired colour to exact customer specifications. Sporty touches such as aluminium shift paddles and race pedals abound.
What about fuel economy? Surprisingly, Brabus claims a low combined fuel consumption figure of 10,3 l/100 km with CO2 emissions of 242 g/km. But good luck in trying to achieve those returns in a 625 kW Brabus…
