Alpina, Tuning
The Bi-Turbo model designation that now graces this flagship BMW ALPINA saloon hints at even more powerful and torque-laden performance over its predecessor, while simultaneously improving upon fuel economy.
The fully-aluminium, 4395 cm3 V8 aggregate yields 507 peak horsepower (373 kW) at a moderate 5500rpm, with a maximum torque of 700 Nm available between 3000-4750rpm.
One look at the torque and power diagram is enough to highlight that the B7 Bi-Turbo will accelerate fiercely and effortlessly from very low revs. Peak torque is available from an unusually broad range of rpm’s, ranging from 3,000 to 4,750 rpm. This wide powerband coupled with the exquisitely geared ZF six-speed automatic sport transmission pampers the occupants with remarkably high levels of smooth drivetrain comfort in every driving situation.
The ALPINA SWITCH-TRONIC, which has been programmed to shift exceptionally smooth and comfortable in Automatic mode, offers different shift characteristics for every taste and situation thanks to the additional Sport and Manual modes. Driving the B7 Bi-Turbo becomes an altogether different experience when using the buttons found on the back of the steering wheel for manually selecting the gears of the automatic transmission. This ensures shifts take place within a few hundred milliseconds and with only minimal interruption to the transmission of power, favourably comparable even to the best twin-clutch transmissions.
As a result, the B7 Bi-Turbo sprints from 0-100 km/h in 4.7 seconds, vehemently pressing on to an electronically-limited 280 km/h top speed.

The new BRABUS B63 Biturbo 6.3-liter V8 engine produces 650 hp (478 kW) and propels the 4×4 to a top speed of 310 km/h. In addition to a superior engine the new BRABUS ML 63 sets itself apart from the rest with the sporty yet elegant WIDESTAR package, forged 23 inches wheels and an exclusive interior trimmed out with leather, Alcantara and carbon fiber. The BRABUS ML 63 Biturbo starts at 190,602 Euros.
The twin-turbo system further includes a large intercooler, a dual-flow intake manifold with cast-in BRABUS Biturbo logo, and high-performance free-flow metal catalysts for efficient exhaust-gas purification.
The high-end B63 Biturbo engine costs 69,800 Euros and offers power on a level previously unknown in the SUV world. With a rated power output of 650 hp (478 kW) at just 6,200 rpm the BRABUS engine surpasses its production counterpart by 140 hp (103 kW). Peak torque of the ML 63 Biturbo is 850 Nm, up from standard 630 Nm. It is available on a wide plateau between 3,000 and 5,500 rpm.
Just as unique in this vehicle category is the performance this engine delivers in concert with a modified seven-speed SPEEDSHIFT 7G-TRONIC automatic gearbox and permanent four-wheel drive: The sprint from rest to 100 km/h is shortened by 0.8 seconds to 4.2 seconds. Top speed increases from 250 to 310 km/h.
The front spoiler bumper with its three strikingly styled air inlets, four auxiliary headlights and daytime running lights lends the M-Class more passing clout and minimizes lift on the front axle. The BRABUS WIDESTAR body conversion further includes door trim components and rocker panels that create a perfect transition between front and rear fender flares. The rear apron features an integrated diffuser and cutouts for the chrome-plated tailpipes of the BRABUS stainless-steel quad sport exhaust system. In combination with the rear spoiler it creates an optimal aerodynamic balance.
The BRABUS control module for the standard AIRMATIC air suspension lowers the ride height by some 30 millimeters which also benefits sporty on-road handling.
To further optimize active safety the BRABUS ML 63 is equipped with a high-performance brake system. 12-piston aluminum fixed calipers grip front discs measuring 380 x 36 mm. The rear axle features six-piston fixed calipers and 360 x 28 mm discs. Together these components provide stopping power normally reserved for purebred sports cars.
The most powerful M-Class ever also features numerous exclusive interior highlights. Stainless-steel scuff plates with illuminated BRABUS logo and an ergonomically shaped sport steering wheel are part of the package as is an exclusive BRABUS fully leather interior made from a perfectly finished combination of the finest Mastik and Alcantara leathers.
Sporty BRABUS ‘Checkered Flag’ carbon-fiber components for the interior are another BRABUS innovation. They have a carbon-fiber surface structure made to look like a checkered flag used as the finish flag in motorsports. The front seats can be fitted with custom rear consoles that encompass the headrests. They each house a seven-inch LCD screen with 16:9 aspect ratio and integrated DVD player. These consoles are also available in a version that features a power-folding precious-wood table.

Why would they build such a machine? It’s pretty simple – because they can. And more importantly, someone will happily cut down the sum of $480,000 to put one car in their collection. Like any real outfit calling themselves a premier German tuner. This time around, they’ve once again outdone themselves for the sake of the buyer and shoehorned their most powerful Mercedes-Benz derived engine - 520kW (700hp), 6.3L, V12 biturbo – into the most unlikely candidate – a G Class purpose-built off-roader.
The most impressive item in the whole Brabus G V12 S Biturbo package is the powerplant. It’s borrowed from an S600 and features an increased displacement from 5.5L to 6.3L via larger cylinders, bore and special cams. A bespoke crankshaft with longer stroke was included internally, while two bigger snails were bolted on as well. Redesigned stainless steel exhausts allow for a louder, deeper tone. A newly mapped ECU keeps the German mechanical madness operating in unison.
Even with all the power, lowered suspension and 22 in alloys, Brabus still clamors that their G Wagon monster is the same true off-roaderas it was straight from Mercedes Given its claimed performance numbers, though, all indications point to it likely never seeing a dirt path in its pampered lifetime. If owners can keep the tires from melting (literally), 100 km/h comes in a scant 4.3 sec before hitting a limited 240 km/h top speed. About entering the corners you can forget, because despite the tuned running gear, the G V12 is still a top-heavy behemoth.
And so as we are used to see only chic accessorized cabins from Brabus interior designers, this roomy SUV, the latest model is all the same, with its great interior. They would make the cabin personally for everyone, anything an owner desires will be there, starting with full multimedia and getting to office connectivity systems. This model is embellished with Mastik leather, alcantara and wood grain on nearly every exposed stock surface, and of course its seats, instrument display and sills are all of the best choice.
