Volkswagen Tayron vs BMW Alpina B5

What's the difference?

Volkswagen has a new large SUV in the Tayron (pronounced TIE-ron), and it arrives with a fair bit riding on it. Replacing the Tiguan Allspace and taking on some of the duties left by the departing Touareg, it’s now the brand’s key seven-seat family offering.

We’re testing the flagship 195TSI R-Line with established petrol rivals like the Kia Sorento GT-Line, Skoda Kodiaq RS and Toyota Kluger Grande in mind. After a few weeks of school-holiday mayhem, complete with feral kids, does it sink or swim?

The BMW Alpina B5 Bi-Turbo is not actually a BMW. Not according to the German Federal Motor Transport Authority, at least.

Nope, the modifications applied by tuning house Alpina to the 5 Series are deemed so significant that if you open the bonnet and look inside the engine bay, you'll see that the BMW VIN has been struck through twice and an Alpina vehicle number stamped underneath it. 

The B5 is not the first model to be recognised in this way, either; the German government has recognised Alpina as a seperate car manufacturer since 1983.

The B5 has other ‘B' siblings, too. There's the B3 S Bi-Turbo, which is based on the BMW 3 Series, the B4 S Bi-Turbo (the BMW 4 Series) and the B7 Bi-Turbo (I don't need to tell you what this is based on, right?) which I've reviewed, too.

So just what has Alpina done to this unsuspecting BMW 5 Series? Is it really worth the extra money? How does the B5 compare to an M5? Could it actually be superior? And did they really take the speed limiter off to let it warp-speed to beyond 300km/h?
