BMW M4 vs McLaren Artura

What's the difference?

To say the BMW M4 CS is a hot ticket in Australia is something of an understatement.

Consider this. There is an even more expensive one, the M4 CS Edition VR46 – at a cool $346,900 – and it sold out in less than an hour. Now, granted, Australia only got four examples, but still, demand was running hot.

That car makes this one, the regular M4 CS, seem like an absolute steal. It's only $254,900 (yes, the word 'only' is doing a lot of heavy lifting in that sentence), and it shares the same upgrades, and makes the same monstrous power, as the VR46 – for Valentino Rossi’s 46th birthday – only it does it for around $100K less.

See? A bargain. At least, that's how I'd be justifying it to myself if I had a quarter of a million burning a hole in my pocket.

So, this or a Porsche 911? Read on.

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.
