BMW Alpina B5 vs Cupra Terramar

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?

There aren’t many cars like the new Cupra Terramar VZe as it’s a mid-size plug-in hybrid flagship that sits firmly at the premium end of the mainstream market. That’s either a huge advantage… or it’s not.

Because when you don’t have a clear set of rivals, you tend to stand out.

There are alternatives, of course. Things like the BYD Sealion 6 Premium, Chery Tiggo 7 Super Hybrid, GWM Haval H6 GT, Mitsubishi Outlander PHEV and Volkswagen Tiguan eHybrid - but they each approach this space a little differently, whether it’s in pricing, positioning or execution.

Which leaves the Terramar VZe carving out a niche for itself. So the question is, does this plug-in hybrid make a compelling case?
