Subaru WRX vs BMW Alpina B5

What's the difference?

The Subaru WRX – do we even need to introduce this iconic beastie at all? With its rally winning roots to being a legend in its own suburb, the ‘Rex’ is a sports car that’s affordable and fun – although the one we’re testing here is one of the pricier versions: the WRX tS Spec B.  

So what is a tS Spec B? Well, the old king of the WRX world – the STI – was retired at the end of the previous generation. Now this new grade – the tS Spec B – is the new WRX monarch. 

So does this mean the tS Spec B has more superpower than the rest of the line-up? Does it have a bigger engine? How much more does it cost? Does it have a manual gearbox? So many questions – the answers are below.

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?
