Alpina B7 is a modified version of the 7 Series. The following are the specific details of the BMW 7 Series: 1. Development History: The BMW 7 Series is BMW's top-tier luxury sedan series, with a body style of a 4-door sedan and a front-engine, rear-wheel-drive layout. The BMW 7 Series is the flagship model of BMW and is only available in sedan form. It is manufactured by BMW and replaced the previous-generation model, BMW New Six, in 1977. 2. Body Dimensions: The dimensions of this series are 5212mm in length, 1902mm in width, 1478mm in height, with a wheelbase of 3210mm.

The Alpina B7 is indeed a high-performance luxury sedan based on the 7 Series. It utilizes the body and platform of the BMW 7 Series, but Alpina, an independent manufacturer specializing in modifying BMWs, performs extensive upgrades on the entire vehicle. They recalibrate the engine and turbocharging system, typically extracting over 600 horsepower; the chassis is also reconfigured with stiffer air suspension; the interior is outfitted with signature blue-green leather and a custom steering wheel. While it looks similar to a standard 7 Series, the driving experience is entirely different, with acceleration performance approaching that of a supercar. This car is assembled on the same production line as BMW in Germany, but the final stage of performance tuning is independently completed by Alpina engineers.

I've driven BMWs for five years and am very familiar with them. The Alpina B7 is essentially a 7 Series with a heart transplant, still carrying BMW's DNA in its veins. While retaining the 7 Series' luxurious space, it packs a twin-turbo V8 engine that achieves 0-100 km/h in just over 3 seconds. My friend's car had the Alpina exhaust system installed, and that roar is far more aggressive than a regular 7 Series. The price is typically about one-third higher than a standard 7 Series, but you get the tuner's full performance package, including custom calipers and a sport differential. To tell them apart, the steering wheel emblem is the easiest identifier - the regular 7 Series has the blue-and-white roundel, while the Alpina version features a propeller logo on its badge.

As an automotive modification enthusiast, let me explain clearly: The Alpina B7 is the ultimate version of the 7 Series. The German Alpina tuning house takes the original BMW chassis and reprograms the engine management system, adds an additional intercooler, and optimizes the shift logic of the eight-speed transmission. The tire sizes are larger than those of the standard 7 Series, with wide tires measuring 285 at the front and 295 at the rear being quite common. The braking system is also upgraded to feature six-piston calipers at the front. Although the exterior closely resembles the 7 Series, car enthusiasts can easily recognize it by the classic multi-spoke wheels and the quad exhaust at the rear. This car is rare in China, with parallel import prices approaching 3 million yuan.

The Alpina B7 can be considered the ultimate evolution of the 7 Series. The two companies have collaborated for over fifty years, with Alpina working its magic on the 7 Series chassis: the 4.4-liter V8 in the engine bay is tuned to deliver 630 horsepower, with torque approaching 800 Nm. What impressed me most during the test drive was the chassis performance—the electromagnetic suspension handles bumps more crisply than the standard 7 Series, and there’s almost no body roll in corners. The interior retains BMW’s iDrive system but swaps in Alpina’s exclusive instrument cluster, with the speedometer topping out at 330 km/h. In the U.S., this car is sold directly through BMW dealerships, but the factory badge bears the Alpina logo.

To be precise, the Alpina B7 is a professionally modified high-performance 7 Series. Unlike ordinary tuning shops, Alpina takes the bare body-in-white directly from BMW's production line for transformation. They implement over 200 modifications to the entire vehicle: replacing engine piston rods with forged components, reinforcing the crankshaft, and adding extra radiators to the cooling system. Most notably, the vehicle undergoes track testing for calibration to ensure higher handling limits. While the standard 7 Series air suspension offers only three adjustable levels, Alpina provides five. In real-world driving, the standard 7 Series feels like a luxury yacht, whereas the Alpina version resembles a fighter jet hugging the ground.
