The next-generation Alpina B5 has been teased, ahead of its likely debut at the 2017 Geneva motor show next month.

Based on the new 'G30' BMW 5 Series, the new Alpina B5 will be a luxury-focused high-performance model, pitched as a more comfortable and conservative alternative to the upcoming BMW M5 performance flagship.

In the new teaser video, the camouflaged sedan can be seen tearing up a snowy circuit, followed by the message "a new Alpina is coming".

Although the company has not confirmed, it is likely the new B5 will make its public debut at this year's Geneva motor show in March, well ahead of the new-generation M5 - which is expected to arrive sometime later this year.

Under the bonnet, it's expected the B5 will feature an uprated version of the outgoing model's 4.4-litre twin-turbo V8 petrol engine - which in its current form develops 441kW.

However, unlike the recently-revealed BMW M550i xDrive, which uses a 340kW/650Nm version of the blown V8 and features all-wheel drive, the B5 will likely be offered in rear-wheel drive.

Despite the lack of all-wheel traction, expect the B5 to post similar performance times to the 4.0-second 0-100km/h figure claimed by its more mainstream relative.

It's unknown whether Alpina will also reveal the B5 wagon alongside the sedan, though both versions have been spied testing in recent months.

Additionally, the German tuning firm is also expected to have a diesel-powered D5 in the works, though it's unknown whether it will also make its debut at the Geneva event.
