Nissan 370Z vs KTM X-Bow

What's the difference?

Road testing the Nissan 370Z in 2011, I noted it was getting on. Yes, the rear-wheel drive two-seater had been given a design freshen up and a bigger engine a couple of years prior, but the 350Z it was based on had hit the local market way back in 2003. And it wasn't unreasonable to expect replacement or retirement in the not-too-distant future.

Okay, so that was seven years ago, which means if you (like many) consider the 370Z to be an update of the 350Z (the transition happening in 2009), this car has been on sale for 15 years straight. Can you imagine Apple trying to sell any one product without entirely reinventing it for that long?

You might say that makes it a modern classic; so good it's only required an occasional touch up to keep it on the Sports Car Most Wanted list. And in recent years, a consistent average of 30 Aussies a month have slotted a shiny new 370Z in their driveway.

But a less-charitable type will tell you time waits for no car, and with arch rival Toyota about to lob a Supra-shaped hand grenade over the parapet, this enduring campaigner is under the pump.

So, Nissan's reached into its bag of tricks and given the 370Z yet another cosmetic tszuj-up and added a high-performance clutch to the manual version.

Is it enough to keep Nissan's eternal Z-car flame burning?

I know what you're thinking: "How is this thing legal?" And to be honest, somewhere between a rock flung from the tyre of a passing car colliding with my forehead like it had been fired from a pistol, and the pouring rain lashing my exposed face like a damp cat-o'-nine-tails, I'd begun wondering the same thing.

The answer is barely. The product of a years-long fight to overcome our import rules, this madhouse KTM X-Bow R is now finally free to roam Australian roads and racetracks - though, with sales capped at 25 per year to comply with the Specialist Enthusiast Vehicle Scheme.

The price? A slightly eye-watering $169,990. That's quite a lot, and places the X-Bow R miles above its closest lightweight, carbon fibre-tubbed competitor, the Alfa Romeo 4C ($89,000).

But then, the KTM X-Bow R is unlike anything else on the road today. Part super bike, part open-wheeler and all mobile madness, the 'Crossbow' is fast, furious and completely insane.

Expect no doors, no windscreen, no roof. On-board entertainment is limited to the turbo whistling behind your head, the car's standard safety list is as barren as the interior and the climate control is dependent on the temperature of the wind that's smashing into your exposed face.

And we couldn't wait to take it for a spin.
