BMW 840I vs McLaren Artura

What's the difference?

Phwoar. Mate!

Or should I say, M-eight-fifty-I. That’s right. This is the all-new, 2020 BMW M850i Gran Coupe, the first ever example of its kind. It’s a big, long, luxury, sporty, coupey thing. And it’s gorgeous.

The BMW 8 Series 2020 range includes this new Gran Coupe body style, and also the Coupe and Convertible models. This particular model, the M850i xDrive Gran Coupe, is essentially BMW’s answer to, say, the Audi RS7. Or one of the many Porsche Panamera variants. Or the Mercedes-Benz CLS or Mercedes-AMG GT 4 door Coupe. 

Like those cars it has svelte looks, striking dimensions and a sledgehammer engine under its long, shapely bonnet. This is first ever 8 Series Gran Coupe, as it essentially stands in place of the existing, now defunct, 6 Series Gran Coupe. But it’s bolder, bigger and more brutal - just take note: this isn’t a full-scale ‘M8’ Gran Coupe. It has more of a luxury speed cruiser angle to it, arguably like a Mercedes-AMG CLS 53, not the full-fat AMG 63.

The question is, then, should you buy it over one of its established rivals?

Let’s figure it out together, shall we?

Obviously the headline item of the new McLaren Artura Spider is the ability to drop the top and feel the wind in your hair, or, should you live in Melbourne, at least the damp mist on your face.

But this new plug-in powerhouse has plenty more to offer than just its folding hardtop.

The coupe and convertible are more powerful, there’s a new and louder exhaust, faster gear shifts, a richer rev range, better suspension and better braking.

Oh, and there's a new feature designed to unlock your inner hooligan, but we’ll come back to that one in just a moment...

But at its core, the Artura Spider is a plug-in hybrid monster that goes someway to previewing the future of the supercar species.

Does electrification enhance the excitement? We strapped in to find out.
