2018 BMW M5 vs. Alpina B5: a Comparison for the Super-Rich

This is by no means something many people think about. Alpina cars are an acquired taste for people with deep pockets and probably an extensive car collection. They even make high-speed versions of the X3 and X5, but sedans are their biggest icons.

We've seen quite a few B5, B6 Gran Coupe and B7 units being shipped to BMW Abu Dhabi. However, this review comes from Autocar magazine, and the only niggle we have with it is that it doesn't include a drag race.

After all, it's not every day that you have two 600 horsepower BMW 5 Series models in the same place. The video has a leisurely pace, which isn't bad at all. Not every BMW needs to be driven to within an inch of its life. But it would be nice to know if the 608 HP Alpina sedan is fast enough.

As the editor mentions, Alina gets early access to all the engineering goodies, which means the B5 Biturbo still draws its power from a 4.4-liter V8. It’s a familiar N63 unit, boasting direct fuel injection and Valvetronic variable valve timing, but with a huge twist. Its tuned 800 Nm output also contributes to a 3.5 second time to 100 km/h.

However, where the M5 is normally limited, the B5 will reach 330 km/h (205 mph). So how does it drive? Well, it feels a little heavier thanks to 85kg of extra bulk. And unfortunately, it doesn't feel more comfortable on a B-road.

So the M5 is the best sports saloon, at least if you want the 5 Series sedan body. What you're left with is probably only the individuality. And remember: you can have a B5 Touring too.
