BMW Alpina B5 vs Leapmotor B10

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?

The B10 isn’t Leapmotor’s first car in Australia - the C10 has been here for more than a year now - but for many it might bring about the first time they hear about the Chinese brand.

The 2026 Leapmotor B10 lands in Australia promising to be the most European of its Chinese compatriots, with the brand’s connection to Stellantis giving it access to other brands under the company umbrella like Alfa Romeo, Maserati and Peugeot.

At its local launch, we get behind the wheel in scorching south-east Queensland to find out if that holds true for this electric small SUV, and to see if the B10 can bring with it a better first impression than the already-arrived mid-size C10.
