BMW Alpina B7 vs Mercedes-Benz C350 E

What's the difference?

You know when you're walking along the footpath and you come to a soft spongey bit that the council have put in around a tree and your mind goes: "Whoah, the ground is bouncy but it looks just like bitumen?!"

Well that's the kind of response you'll get from people when they think they're looking at a regular BMW 7 Series, only to have their world go a bit bouncy when they see the Alpina B7 badge on the back of this car as you're overtaking them at Warp Factor 9000.

And you will be overtaking them like a blur because, thanks to the elves at German tuning house Alpina, the B7 is hugely fast for a five-seat, 5.3m-long, 2.2 tonne limo. But then the B7 is fast for any type of car of any dimensions, because with its 330km/h top speed this beast will outrun a McLaren 570GT. Yes, seriously.

Based on the BMW 750Li long wheelbase, the B7 begins life rolling down the same production line as a regular 7 Series. Alpina then goes on to make so many changes to the engine and chassis that the German government requires the BMW VIN to be replaced with a new one.

Ready to find out more? Well there's so much to see here that things may go a bit weird and bouncy again. Be prepared.

They're doing it again! Actually they've been doing it again for a bit now. It’s Mercedes-Benz Australia and plug-in hybrid tech.

The Ross and Rachel, or Jim and Pam of the premium automotive world.

It's been a will they, won't they for a while, and in the past Mercedes has dipped its proverbial plug into the electrons a few times and gotten cold feet.

But now it says it’s all in. There are others, the GLA and GLC SUVs, plus there’s the new C63 performance car, but this one feels like a bit of an arrival.

Yeah, the C-Class is no longer the Mercedes-Benz in terms of sales, but it might be the best way to make the most of a bit of battery power.
