BMW Alpina B5 vs Mazda 6

What's the difference?

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?

Has it really been 20 years since the humble Mazda6 station wagon hit our roads? You betcha, but I was more shocked that I remembered when it did!

I have a sudden flashback of questionable fashion choices, glittery butterfly hair clips and how Skipper was making a play at being the coolest 'Barbie' (she wasn't).

I've always had a soft spot for wagons, they are the forgotten heroes for family hauling. It's hard not to glide over them when the market is dominated by SUVs but if you happen to remember they still exist (albeit, barely) you might remember why they were popular back in the day.

Being a 20th Anniversary Edition means there are some nods to the past in this model but unlike the low-slung jeans of my youth, they're stylishly done. With some luxuriously-appointed rivals to contend with, like the Skoda Octavia and Volkswagen Passat, does it offer enough to be considered by a modern family?

My little family of three has been in it all week to find out for you!
