The Alpina B5 Bi-Turbo Touring Is The Fastest Series-Production Estate In The World

If you want the most performance-focused BMW possible, you’d be wise to choose a vehicle from the M range of vehicles. However, if you want a vehicle that offers similar performance but combines it with greater comfort, it is hard to look past some of the products in Alpina’s range. Out of all the cars it offers, it is perhaps the B5 Bi-Turbo which is the best all-rounder, particularly in Touring guise.

Based around the 5-Series estate, the Alpina B5 Bi-Turbo Touring is powered by a twin-turbo 4.4-liter V8 engine pumping out 608 hp and mated to an eight-speed automatic transmission. Like the M5, this grunt is sent through all four wheels and the Alpina is capable of sending up to 90 per cent of torque to the rear wheels if needed.

Thanks to Alpina’s expertise in creating high-performance vehicles, the B5 Bi-Turbo Touring is very quick. In fact, it can sprint to 62 mph (100 km/h) in a blistering 3.5 seconds and continues through to a top speed of 200 mph (322 km/h) as this new video shows.

However, truth to be told, a big difference with all the other series-production performance estates is that Alpina does not electronically govern the Touring’s top speed at the usual 250km/h (155mph) mark, allowing it to brag about it being the “fastest production Touring in the world”.

The clip from Alpina shows both a Porsche 911 GT2 RS and Mercedes-AMG GT R sprinting along a straight section of road. However, both are forced to make way for a fast-moving Alpina coming up behind them. Not only is the Alpina going faster but we imagine the occupants are much more comfortable than they are in the Porsche or Mercedes.

Making the Alpina all the more desirable, particularly for those that don’t want to make a statement, is that its design is very simple and refined compared to an M5 sedan. It really is the ultimate German sleeper.
