2020 Alpina B7 xDrive Sedan: Blasting across Germany, in comfort, at near-hyperspace

An Alpina sits somewhere between a BMW and an M. The philosophy behind the products is not just to make the big bruiser Bimmers better performers — that’d be more like making M clones. Alpina increases performance significantly, but also ups luxury.
Let’s start with the performance. The Alpina in question here is the 2020 Alpina B7 xDrive sedan. It’s based on a BMW 750i xDrive. The “B” in B7 stands for “benzine,” or gasoline. They also make “D” models with diesel engines. In BMW trim out of the factory in Dingolfing, the 4.4-liter twin-turbo V8 in a 2020 750i xDrive makes 523 hp and 553 lb-ft of torque. Alpina starts with that and adds bigger turbos, bigger intercoolers (with an “interconnection” between the cylinder banks to reduce pressure pulsations), and tweaks the engine management system. The result is 600 hp and 590 lb ft of torque in the Alpina.
“This leads to significantly improved throttle response, more engaging power delivery and an effective performance gain in the most relevant engine range,” says Alpina, in as close as German engineers get to gushing.
The 2020 car’s 0-60 time drops from 4.4 seconds stock to 3.5 in Alpina trim. Likewise, top speed goes from 130 mph stock (155 optional) to the above-mentioned 205 mph.
