Mercedes-Benz E-Class vs BMW Alpina B5

What's the difference?

You like performance, love a bit of luxury and fancy a traditional sedan. The budget is healthy and there’s a surprising amount of choice. But Mercedes-AMG believes it’s created the car that perfectly answers your new-car brief. 

The Mercedes-AMG E53 Hybrid 4Matic+ is a fresh expression of an established high-performance sedan formula mixing internal-combustion power with electric punch and all-wheel drive.

We were invited to its local launch, so stay with us to see if this newcomer is ready to fill that primo European performance car shaped space in your garage.      

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?
