With BMW preparing a mid-cycle refresh for the 5 Series, it goes without saying that Alpina’s version will follow suit.
Here we have the facelifted Alpina B5 Biturbo Touring spied for the first time – also referred to as the unofficial M5 Touring that BMW has stubbornly refused to make since the V10-powered E61 generation (not to mention bring to North America). The prototype wears camouflage at the front and rear ends, indicating where the most important exterior updates will take place.
The facelifted Alpina B5 Biturbo will feature the same slimmer headlights as the 2020 BMW 5 Series, new LED taillights, and a slightly wider grille. Alpina’s products have always been known for their restrained looks but it seems that the facelifted B5 Biturbo will be bolder in that respect.

The Touring prototype sports a more aggressive front bumper with air intakes and a spoiler lip wearing the signature ‘Alpina’ lettering. Also part of the package are the slightly sharper side skirts and quad exhausts piercing through the revised rear bumper. The typical multi-spoke Alpina wheels round off the exterior treatment for the B5 Biturbo Touring.
It remains to be seen whether the diesel-powered Alpina D5 S will feature the same look or adopt a more subtle body kit. Of course, there’s also the possibility that Alpina will let the customer choose between two body kits.
We don’t expect big changes in the engine compartment as the potent 4.4-liter twin-turbo V8 will likely carry over. Alpina B5 Biturbo will likely carry over. In the current model, the engine delivers 608 PS (600 HP) at 5,500 – 6,500 rpm and 800 Nm (590 lb-ft) of torque between 2,000 – 5,000 rpm.
That’s enough to enable a zero to 100 km/h (0-62 mph) sprint of 3.7 seconds and a top speed of 322 km/h (200 mph) for the Touring – or 3.5 seconds and 330 km/h (205 mph) for the sedan. This stunning level of performance makes the Alpina B5 Biturbo Touring the fastest series-production wagon in the world, a title the facelifted model will likely keep.
