Audi R8 2018 review: RWS

The R8 RWS exists largely because Audi was developing a rear-wheel-drive setup for its LMS race car, and so rather than simply waste the engineering effort, it will instead release a limited-run of rear-drive R8s. It's a trick surely learned of its Lamborghini stablemate, which has found huge success with its own rear-drive special editions.

And we do mean limited; just 999 are planned worldwide, with a mere 40 of those scheduled for an Australian debut.

The grille and vents are in flat black instead of high gloss.

Owning one will cost a cool $299,500 in the Coupe guise we've just tested, or $321,000 for the folding-roof Spyder version. Not chump change, sure, but something of a bargain at this end of the market - especially considering it essentially lifts a Lamborghini engine -  and officially the cheapest R8 currently on offer in Oz.

Your money buys you new 19-inch alloy wheels, LED headlights and a booming sports exhaust outside, while inside you'll get seats (that are also heated) trimmed in Alcantara and leather, a flat-bottomed steering wheel perched in front of two paddle shifters, climate control, navigation and DAB+ digital radio.

As per Audi's sports car philosophy, there's no central infotainment screen. Instead, the key controls are operated by Audi's Virtual Cockpit (a 12.3-inch digital screen that fills the driver's binnacle).

The tailpipes and the rear diffuser are all uniquely coloured, too.

It looks, well, a lot like any other V10 R8 (though sans any Quattro badging, of course). Bespoke stuff includes the 19-inch alloy wheel design, and the grille and vents are in flat black instead of high gloss. Those iconic side-blades, the tailpipes and the rear diffuser are all uniquely coloured, too.

The sleek, air-slicing profile and a swept-back roofline draws your attention to that glass-topped view of the massive V10 engine housed almost directly above the rear axle.

Apart from that, though, it's business as usual for the R8 RWS, which is no bad thing for Audi's largely timeless supercar design; think two doors, two seats, a sleek, air-slicing profile and a swept-back roofline that draws your attention to that glass-topped view of the massive V10 engine housed almost directly above the rear axle.

Inside, the RWS is plenty driver-focused, not least of which because the screen-free dash means it's only the person behind the wheel who can control - or even see - the car's main functions. But it also makes the cabin feel clean and fuss-free.

Um, next question? If you're shopping for something ridiculously quick and ridiculously expensive that can also ship cargo or people, may I draw your attention to Audi's RS6 Avant? Or even Jeep's Grand Cherokee Trackhawk?

The R8 RWS, on the other hand, is very good at moving exactly two people along at a ferocious clip. You will, however, find 112 litres of storage in its boot (located under the bonnet, of course) which is enough to stow a couple of soft overnight bags.

Inside, the RWS is plenty driver-focused.

In the cabin, expect a pair of cupholders, a small-ish glovebox and a storage net in each of the passenger doors. There are no ISOFIX attachment points, of course, and there are no rear doors let alone bottle storage in them.

Where the R8 is practical, though, is in its approach to weight loss. Its space-frame underbody is made of 79 per cent aluminium, and the entire structure weighs just 200kg. And ripping out the all-wheel-drive architecture has shaved another 50kg off the kerb weight, which is now 1590kg.

It's a work of petrol-pumping art, this mid-mounted 5.2-litre V10 engine, which will send 397kW at 7800rpm and 540Nm at 6500rpm positively thundering toward the rear tyres.

That power passes through a seven-speed S tronic dual-clutch automatic, pushing the R8 RWS to 100km/h in 3.7 seconds (3.8sec in the Spyder version), and on to a screaming top speed of 320km/h (318km/h in the convertible).

It's a work of petrol-pumping art, this mid-mounted 5.2-litre V10 engine.

Yeah, that's not a good story. Audi puts the combined figure at a claimed 12.7 litres per hundred kilometres. But if you spend most of your time in the city, that number climbs to 19.2L/100km on the urban cycle.

The big V10 can shut down five cylinders when you're cruising to help conserve fuel, the system doubling as a handy dynamic aid, closing off the engine's outside bank when cornering to push more weight toward the corner.

Emissions are a claimed 291g/km of C02, and the R8's massive 83-litre tank demands 98RON fuel.

What's more important to you, outright pace or outright fun? Because even without having driven them back to back, it's hugely unlikely the R8 RWS would stay glued to the bumper of the all-wheel-drive version on a racetrack or a twisting road.

But you know what? You would watch the AWD version slowly extending its lead with a huge and face-splitting grin, not a care in the wide world. And that's because this RWS is so much fun.

From its comically loud and booming exhaust to the way it absolutely charges through its seven gears, zero let up in its epic power delivery, the rear-driving RWS leaves you grinning like a lunatic. And if that is not what you're buying a supercar for, then you're shopping in the wrong place entirely.

What's more important to you, outright pace or outright fun?

Don't get me wrong, the rear-driving R8 is still ferociously fast; punching through the 100km/h barrier in just 3.7 seconds. It feels every bit that quick, too, the gearbox seriously rapid in selecting the right gear, and happily clinging to a lower cog - even as the engine howls - when in its most dynamic setting.

And on a racetrack or a twisting road, the rear-drive R8 feels plenty sharp, although you will notice the traction control stepping in far more often as the rear tyres struggle with putting the power into the tarmac. Setting the traction control to its sport setting (allowing for some traction loss before pulling the R8 back into line) is the fastest tactic.

From its comically loud and booming exhaust to the way it absolutely charges through its seven gears, zero let up in its epic power delivery, the rear-driving RWS leaves you grinning like a lunatic.

The steering is near-perfectly weighted, light enough at city speeds and firming up considerably when in Dynamic mode, and it's like it has a new and improved relationship with the front tyres, too, with the RWS serving up easy direction changes through sharp slaloms, the rear end pushing wide only when seriously provoked.

The R8's true party trick, though, remains its ability to tone down the mayhem and transform back into a calm and composed daily driver when you want it to, happily carrying you away from a twisting road or race circuit and back into the daily grind. The RWS remains a super comfortable and easy runabout -  one you'd have no problem ducking out to pick up the milk in.

A fairly basic package, that starts with a reversing camera, parking sensors and six airbags (two front, two side and two side-chest bags). The Spyder makes do with four airbags, but adds automatic rollover detection.

The R8 has never been tested by ANCAP or Euro NCAP.

Audi's standard three-year, unlimited-kilometre warranty is the order of the day here, with service intervals pegged at 12 months or 15,000kms.

While the bulk of Audi's fleet is covered by a service plan that publishes servicing costs on the brand's website, the R8 range doesn't qualify.
