2020 BMW Alpina B5 Summary

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?

2026 Denza B5 Summary

BYD has achieved much success in recent years in Australia and it's now branching out with a new, more premium brand.

Denza is like the Lexus to Toyota and it’s launching in Australia with two large body-on-frame plug-in hybrid (PHEV) SUVs – the B5 and B8.

The former is on test here and its rivals include mainstream models like the GWM Tank 300 PHEV, however it also pitches itself against more premium offerings like the Land Rover Defender.

We’ve already driven the B5 over in China and this is the first time we’re getting to test it out on Australian roads, so let’s see how it fares.
