There was never a BMW 7 series made by the M division, there was no M7 badge, except for cheap sellers, somewhere around the world. There is though a small BMW tuner, who does the job for the 7 series, and they make it exquisite. The name of this tuner company is of course Alpina. The model in question is the BMW Alpina B7, presented in the Monterey Car Week

The original car was the 750i, Alpina added power, sportiness and class to it. Alpina did some work on the twin turbocharged 4.4L V8, working on the turbochargers, air intake and cooling systems, and the exhaust system. They came with more developed turbochargers with twin-scroll turbines and larger compressor wheels. They placed all of it in the V to ensure a more effective use of the exhaust gas even at low speed, and it resulted at better engine responsiveness. The total boost now is around 20 psi from the twin-turbos system. In addition to that, Alpina did modification to the air intake and cooling system. All components (raw air intake ducts, air filter housings and clean air intake manifold) guarantee maximum effectiveness. The cooling system uses new larger radiators and optimized piping. The Alpina B7 has an indirect intercooler system (air/water/air) to ensure better thermodynamic exchange, and higher performance. It has also a new stainless steel twin-pipe exhaust system that guarantees weight loss, better sound, better exhaust of the gas with less pressure. The new tweaked engine produced 608 bhp between 5750 and 6250 rpm, while the maximum torque of 800 Nm is available from just 3000 rpm. Power is put to the ground via the new generation 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC from ZF and an all-wheel-drive system which is an improvement to BMW’s x-drive system. The transmission comes with a stronger torque converter, reinforced planetary wheels, increased cooling, and unique software, and works in three modes : Automatic(D), Sport (S) and Manual (M). Racing from 0 to 100 kph takes just 3.7 seconds (big improvement compared to the 750i engine that does it in 4.3 seconds), and the top speed is around 330 kph.

On the exterior, Alpina left its mark, and came with new aerodynamic and aesthetic elements. The body is reinforced with Carbon-fiber, steel and aluminum for weight reduction but also for better mechanical resistance. The Alpina B7 has new and rear front spoiler, that reduce drag, and increase lift on the front tires, also to cool the front brakes. It also had an active grille that plays a good role in the cooling. Also, as you can see, this is a long-wheel-base model, and sits on Alpina classic 20 inches wheels.


On the interior, Alpina fitted the B7 with luxurious equipment. The seats are covered in Hand-finished LAVALINA leather. Alpina promises luxury and comfort. The instruments panel uses LED technology that reacts with the driving mode, either in comfort, or in speed and dynamic view.
