BMW Alpina B4 vs Mercedes-Benz C63

What's the difference?

If you're looking for a sleek, two-door coupe with a sparkling chassis, rear-wheel drive and a charismatic turbo straight-six, BMW has you covered with about eight choices. That should be that, then. But wait. There's more. 

Since 1965, Alpina - the name of a resurrected a typewriter company - has collaborated closely with BMW to produce distinct, high performance Alpina-badged cars. It actually started with a Weber dual-carburettor unofficial conversion for the BMW 1500 in 1962 and over the years built into a racing operation winning championships and races like the Spa 24 Hours.

Alpina returned to Australian shores in 2017 after a long hiatus with a new range including the BMW 4 Series based B4. Not long after, BMW updated the 4 in what it calls LCI (Lifecycle Impulse), so Alpina followed suit with a price drop, new gear and called it the B4 S.

If you know the Mercedes-AMG C 63 S, you know it’s a hardcore V8 thumper with little in the way of bashfulness. It’s a brawler. A beast. 

Now there’s an even more eye-catching AMG C 63 S Coupe, which we’re testing here. It’s the Aero Edition - a collector’s version of the current-generation C 63 S Coupe with a bit more visual bling that also helps it stick to the road better.

It is a local area special edition, with only 63 examples to be sold across Australia and New Zealand. And if the rumours are true, the next-generation will see the V8 engine in danger of being axed in favour of a hybrid, high-performance four-cylinder version. Say it ain’t so! 

Well, if the CarsGuide crystal ball turns out to be right, maybe one of these C 63 S Aero Editions is worth getting in your garage quick-smart. Or is it? Let’s go through the criteria and see how it stacks up.
