BMW Alpina B5 vs BYD Atto 1

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?

Back in 2010, Mitsubishi released Australia’s first mainstream electric vehicle (EV) in nearly a century.

That model, the i-MiEV, was a four-seater city-sized Kei car from Japan that cost $48,800, before on-road costs, or from roughly $70,000 in today's money. Little wonder it bombed. That was four times more than petrol-powered equivalents of the time.

Now, in 2026, the new BYD Atto 1 is the first EV sold here since the i-MiEV’s 2013 departure to be considered a four-seater city car.

It’s also the least-expensive EV money can buy, being even cheaper than many internal-combustion engine alternatives like the Mazda 2 and Toyota Yaris hybrid. The fact is, there’s nothing remotely near the Chinese supermini’s base price that’s electric.

But is the Atto 1 any good?
