Kia Stinger vs BMW Alpina B5

What's the difference?

There is nothing quite like a car company occasionally building a car that could be considered a risk. And there are all kinds of risks in the car business - the market isn't ready for that car, people don't identify your brand with this or that type of vehicle, the list goes on. And it's long. It's very easy for me to sit on the sidelines and say, "Pft, what were they thinking?" Few cars land on your driveway without years of thinking having already gone into their development.

The Kia Stinger is the kind of car that would have caused lots of thinking and plenty of hand-wringing at Kia HQ in Korea. Not because it was a bad idea - it wasn't. Not because it's a bad car - it is, in fact, the opposite. And not because SUVs have already changed the way we look at cars - Kia has done well out of that.

It's just that Kia has never produced a car like the Stinger. A five-door coupe-sedan, rear-wheel drive and with a focus on driver dynamics. Most of us know very well how the Stinger GT burst on to the scene in a blaze of well-deserved glory. It's not all about the GT, though. There's a whole range of Stingers and just below that very accomplished sports sedan is the Stinger GT-Line.

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?
