Audi R8 vs Porsche 911

What's the difference?

The Audi R8 V10 RWD and V10 Performance Quattro have their own personalities. I'm a big fan of the lower-powered rear-wheel drive car, but the Performance is the ultimate here with better brakes and that 330km/h top speed. Either way the R8 is a true supercar, but one that doesn't have to be driven gingerly as though something may break off.

In describing this 911, Porsche talks about the 'T-feeling'. It should be light and agile, delivering fun, driving pleasure, yet still suitable for everyday use.

Sure, the safety could be better and the warranty lags the market, but that stuff fades into the background when the T feeling takes over. What a great car!

Lamborghini styling can look over the top, McLarens can sometimes appear delicate and fragile, and Ferraris seem to be everywhere, and even for me, begin to blend into one.

The R8, though, looks exactly how an Audi supercar should look – understated, tough and serious. Have you seen that Audi advert with the R8 on a dyno not wearing any pants? That sounds ridiculous but Google it because it sums up what the R8 is – a real car with a raw race car underneath, that's meant to be driven comfortably on the road and hard on a race track and the styling indicates that intent with little in the way of fanfare.

Well, there is that big window at the back which shows off the engine and the 'side blades' that surround the large vents carved into the side of the car to cool the engine.

The latest update has taken the design from the second-gen car which arrived in 2016 and added a new grille, front bumper, door sills and vents in the rear bumper. It's a more angular, sharper, and busier design with more vents and winglets than ever.

The R8 V10 RWD and R8 V10 Performance are close to identical in their styling. You can pick the Performance by its gloss carbon front spoiler, side sills, mirror caps and rear diffuser. The RWD has gloss black elements instead.

Which looks best: the Coupe or Spyder? That's a personal thing, but I reckon race cars need to have a hardtop roof, so it's the coupe for me, please.

Built using the 'Audi Space Frame' which weighs only 200kg, the R8 is 4426mm long and just 1240mm tall, but at 1940mm across it has a wide, planted stance.

One of the most recognisable profiles in the automotive world, the 911 has evolved and grown over time but there's no mistaking it for anything other than Zuffenhausen's finest.

For the record, the current '992' 911 is a whopping 367mm longer, 242mm wider and 30mm lower than the 1963 original. And the majority of models share the same (1852mm) wide-body look, the Turbo and GT3 RS broadening that to 1900mm.

Multiple solid and metallic colours are available at no extra cost, three of which are exclusive to the Carrera T, but if you like our test car's 'striking' 'Python Green' finish, it'll set you back an extra $5700.

Car-spotters on the lookout for the Carrera T will need to tick off 'Agate Grey' accents on the tail-light grille, badging and mirror housings as well as a grey top tint windscreen, specific side graphics and Carrera S wheels in 'Titanium Grey'.

The cabin in our test car also has also been optionally upgraded with the 'Carrera T Interior Package' ($4120), which adds extra leather trim as well as coloured seat belts and contrast stitching.

Our car has also picked up the 'Adaptive Sports Seats' ($5510). Subjective call, of course, but I love the dark cloth seat inserts with tiny flecks of green. It's Porsche retro-cool, but somehow contemporary at the same time. Beautiful.

And the five-dial instrument cluster under a gently curved cowl is a 911 design signature, although the central tachometer is now flanked by twin 7.0-inch, configurable displays.

Ergonomically and aesthetically, this layout is hard to fault.

The R8 is a two-seater supercar and practicality isn't high on its 'to do' list with limited cabin storage in the form door pockets almost as small as my jeans pockets, two cupholders hiding under a trapdoor in the centre armrest, a hidey hole in front of the shifter containing a wireless charger and two USB ports and the glove box.

As for the boot – there are two: one in the nose with a 112-litre cargo capacity and another behind the mid-mounted engine with 226 litres.

Room for people, well you and a friend, is excellent. I'm 191cm (6'3") tall with a 2.0m wingspan and found the footwell deep and spacious, while head and shoulder room is also good.

Even though the current 911 dwarfs the original '901' series of sixty years ago, it's still aimed primarily at accommodating the driver and front passenger, with '+2' rear seating a handy addition for kids, or adults in short trip emergencies.

In other markets, the addition of the rear seats is a no-cost option, whereas here they're the default fitment and removing them is the zero-dollar choice. Which makes sense because they add significantly to the car's usability.

Either way, a sports car of this type is never going to be SUV practical. However, when you look at it in the context of the Carrera T's competitors, this 911 does pretty well.

It feels appropriately snug inside, yet there's more than enough breathing space in the front and a liveable distance between driver and passenger.

For storage there are two slim compartments in each door, with a cavity for bottles, as well as a cupholder in the centre console and another pop-out holder in the dash on the passenger side.

As in most 911s, you can swap the centre console cupholder out with a small oddments tray insert which is a nifty piece of practical thinking.

There's also a modest glove box, a shallow lidded compartment between the seats and clothes hooks on the front seat backrests.

Connectivity and power options run to a pair of USB-C ports in the centre console box and a 12-volt outlet in the passenger footwell. Nothing in the back, which isn't a big surprise.

And the 132-litre boot is the only substantial cargo space, with enough room for several soft bags or a medium suitcase… even a mid-week grocery top-up.

Luggage-type storage inside the car is helped by the rear seat backs folding down to create a level platform.

But bear in mind there's no spare. A can of sealant and air compressor are on board instead.

We might be at the lower end of the 911 price spectrum, but cost-of-entry for the Carrera T is still north of $300K ($300,700 before on-road costs).

At that money there are some tasty alternatives circulating in the same price pool, like the BMW M850i xDrive Coupe ($298,100), Jaguar F-Type R ($283,020) and Mercedes-AMG GT Night Edition ($294,077), but the Carrera T stands up well in terms of included features.

On top of the performance and safety tech we'll get to shortly, standard equipment includes dual-zone climate control, 570-watt Bose surround sound audio, 'Porsche Communication Management' (PCM) including 'Online Navigation' (with voice control), 'Porsche Connect' with wireless Android Auto and Apple CarPlay and digital radio as well as four-way electric heated front seats and a heated leather-trimmed steering wheel.

There's also auto-dimming interior and exterior mirrors (the latter electrically-folding), auto rain-sensing wipers, a 10.9-inch multimedia touchscreen display, twin 7.0-inch configurable instrument screens, metallic paint, Carrera S alloy wheels (20”/21” up from 19”/20”) and LED matrix headlights. The combination of adaptive cruise control and AEB is a no-cost option on the dual-clutch auto version.

Overall, it's a nice balance between creature comforts and this car's focus on a pure driving experience.

There are two grades in the Audi R8 range – the entry-point R8 V10 RWD which has rear-wheel drive (RWD), and the R8 V10 Performance Quattro which has all-wheel drive (AWD).

Both obviously have V10 engines, it's a naturally aspirated 5.2-litre petrol unit (so no turbos here), but the RWD makes less power and torque at 397kW and 540Nm, while the Performance produces 449kW and 560Nm.

The V10 is mounted behind the driver's seat but ahead of the rear axle making it mid-engined car. The engine even has its own window and you can see it in there with its face pressed up against the glass.

There are two body styles as well – the Coupe and Spyder (convertible, roadster, just another word for a retractable soft roof). We'll get to the prices in the next section, but let's talk about the more interesting numbers such as top speeds.

The V10 RWD in coupe form can reach 324km/h and the Spyder can hit 322km/h while the V10 Performance Coupe and Spyder are both a smidge quicker at 330km/h.

Those are all go-straight-to-jail speeds in Australia, so if you're tempted to fact check my numbers then do it on a racetrack. Audi holds excellent track days – I've done them and you'll not only get to drive the R8 as fast as you can, the instructors will help you improve your advanced driving skills, too. Do it, it could save your life.

Acceleration from 0-100km/h is rapid – 3.7 seconds and 3.8 seconds for the V10 RWD Coupe and Spyder respectively, while the V10 Performance Coupe and Spyder can nail it in 3.2 seconds and 3.3 seconds.

The V10 engine has a cylinder-on-demand feature which can shut down five of the cylinders while cruising on a motorway, say at 110km/h. It's a fuel-saving system, but keep in mind this V10 loves petrol and lots of it – I've hidden that all the way down the bottom of this review.

Shifting gears in all R8s is a seven-speed dual-clutch automatic transmission.

One of the saddest things about recent 911s is the fact that when you open the cover you can't see the engine unless you decide to break out the spanners and remove everything that's hiding it.

If you did, you'd reveal a 3.0-litre, all-alloy, dry-sumped, twin-turbo flat six-cylinder engine which remains unchanged from the entry Carrera model.

Featuring direct-injection and variable valve control, it sends more than 280kW (380hp) and 450Nm (from 1950-5000rpm) to the rear wheels through a seven-speed manual gearbox, or in this case, the no-cost optional eight-speed dual-clutch auto.

Suffice it to say, in a car weighing less than 1.5 tonnes, that's plenty of propulsion, and even though an engine hanging over the rear axle remains a peculiar 911 throwback, the white-coated boffins in Stuttgart continue to make it work brilliantly well.

That's like asking how many calories are in this pavlova that I'm about to push into my mouth? Seriously if you're asking then you shouldn't be eating it – or driving the R8.

But just for the record, according to Audi the RWD R8 uses 12.0L/100km in Coupe form and 12.2L/100km in Spyder guise after a combination of urban and open roads, while the AWD R8 of course will use more at 13.4L/100km for both Coupe and Spyder.

Porsche's official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.8L/100km for the dual-clutch auto as tested, the 3.0-litre twin-turbo six emitting 246g/km of CO2 in the process.

During a week of city, suburban and some at times enthusiastic highway running, we averaged 15.0L/100km (at the pump), while the car's onboard computer indicated 16.1L/100km, which isn't out of line with the super- and turbo-charged V8s this car competes with.

Minimum fuel requirement is 98 RON 'premium' unleaded and you'll need 64 litres of it to fill the tank.

Using the official number, that translates to a driving range of around 590km, which drops to roughly 430km using our real-world figure.

A race circuit is the best place to test the performance of an Audi R8. I've been lucky enough to have done this in the past, but for this update of the R8 the Australian launch was held on public roads and included a convoy of RS models such as the RS 6 Avant, RS 7, RS Q3 and TT RS.

Even then I think I was 'stitched up' because I began the day in the R8 V10 Performance Coupe but spent almost the entirety of my allocated time in roadworks at 40km/h before swapping to an RS Q3.

So, while I can't honesty comment about the dynamics on this updated R8 V10 Performance Coupe I can tell you that having driven every iteration of the R8 since 2012 that it's a weapon, with helicopter-like visibility out of that large front window.

If, like me, you think turbos are 'cheating' (superchargers are fine), then you'll love the linear power delivery of the R8's naturally aspirated V10, and while I love front-engined sportscars, nothing beats a mid-engined car for the feeling of balance and lightness in the nose while having the sound of thousands of explosions going off just behind your back.

Having AWD is not just great for acceleration and perfect traction from Audi's quattro system, I think it's a good safety feature in a supercar, and while only your judgements can stop things going pear shaped, the system will be there to help on slippery roads.

The following day was different. I was in the R8 V10 RWD, the country roads were superb and while it wasn't a racetrack it was enough to get a hint of the capabilities of the RWD R8.

While the R8 V10 RWD feels the same to sit in with the same great view, it feels different to drive than its faster sibling, in a good way. First there's the noticeable power difference – more than 50kW and 20Nm less – but also the lack of AWD makes the front end feel more pointable, and the car feel more like a traditional sportscar that pushes from behind rather than pulling from the front. Less power, but more fun.

The RS cars in our test convoy were all awesome machines, but stepping out of even the RS6 Avant and slipping down into the R8 cockpit was like getting into a UFO – it's so far ahead dynamically of any other Audi that all I could do was laugh like an idiot. Corners which were making an RS 7 really struggle, were handled effortlessly by the R8. And in a straight line it's a bullet in a barrel.

The Performance has the better brakes: 380mm ceramic discs with six piston calipers up front and 356mm discs with four piston calipers at the rear. The RWD has steel discs – 365mm with eight piston calipers up front and 356mm discs with four piston calipers in the rear.

Keep in mind if you are planning on track days, you'll find the ceramic discs costly to replace, and beside the stopping power of the steel ones is excellent.

And yet, on pot holed course bitumen the ride is a lot more comfortable than you might think and having driven the Performance in traffic it's a much nicer place to sit than the claustrophobic cabin of a McLaren 570S. You could honestly use the R8 daily.

At 1470kg the 911 Carrera T is 35kg lighter than the entry-level car it's based on, thanks largely to reduced sound insulation, lightweight glazing and a more compact battery.

Yes, the rear seats are fitted to our test example, which sends the scales back up a bit, but the reduced sound deadening still raises the standard sports exhaust's glorious rumble through the cabin.

Porsche claims 0-100km/h in 4.0 seconds for the auto and 4.5s for the seven-speed manual. Yep, it's quick!

Peak torque (450Nm) is on hand from 1950-5000rpm, which means there's always substantial mid-range punch available, with the dual-clutch auto's eight ratios also helping to keep things on the boil.

I love a manual gearbox as much as the next person, but this dual-clutch is ultra fast yet refined with the wheel-mounted paddles adding to the fun.

The 'Driving Mode' dial on the steering wheel enables selection of 'Normal', 'Sport', 'Sport Plus' and 'Individual' modes, with each selection displayed in the instrument cluster.

And given the 'Sport Chrono Package' is standard the 'Sport Response' button in the centre of that mode dial acts like a push-to-pass function, delivering a 20-second burst of maximum performance response from the engine and transmission.

Suspension is by struts at the front and multi-links at the rear, with ride height dropped by 10mm and the standard 'Porsche Active Suspension Management' (PASM) system able to adjust the dampers through 'Normal' and 'Sport' modes.

Ride comfort is harsh, even in the most comfort-focused setting, but that kind of goes with the Carrera T territory.

The steering is pretty much perfection. Precise and accurate, with amazing road feel, it allows the old 'think your way through corners' syndrome.

Speaking of which, this car chews up and spits out twisting B-roads without a hint of drama. The front end sticks and refuses to let go, the big 305 rear rubber following suit.

It remains resolutely planted, balanced and adjustable on the throttle, the standard torque vectoring set-up and locking diff turning go-fast wannabes into bonafide apex predators.
  
Standard rubber is Z-rated Goodyear Eagle F1 (245/35x20 fr - 305/30x21 rr) which is 10mm wider than the already generously shod 911 Carrera.

Braking is suitably beefy with 330mm ventilated and cross-drilled rotors all around clamped by four-piston aluminium monobloc fixed calipers front and rear.

We got the bit between our teeth at various stages of this test and can confirm the brakes are able to wash off speed rapidly and consistently with a reassuringly firm yet progressive pedal.

Under the heading of miscellaneous observations, the optional 18-way adjustable Adaptive Sports Seats fitted to the test car are brilliant. Comfortable for cruising, they can be dialled up to King Kong levels of grip when required.

A super useful feature is the ability to adjust the passenger seat with the driver's seat controls. So convenient for setting things back to normal after the co-pilot has cranked forward to accommodate a rear seat passenger.

The GT sport steering wheel is just right in terms of its diameter and grippiness and the overhead 'Surround View' function helps when manoeuvring a low and wide-hipped car like this one.

Although it hasn't been assessed by ANCAP, it's safe to say the 911 isn't at the leading edge in terms of active safety.

There's 'Lane-Change Assist', which is effectively Porsche's take on blind-spot monitoring, the combination of adaptive cruise control and AEB is a (no-cost) option on the dual-clutch auto version only, and tyre pressure monitoring is included. But common features like lane departure warning and rear cross-traffic alert are missing in action.

That said, in wet conditions the 911 will prompt the driver to engage the aptly named 'Wet Mode', which lowers the activation threshold of the ABS, stability and traction control systems, softens drivetrain response, and to improve stability, the degree of diff locking is reduced and the rear wing raises to its maximum position.

If a crash is unavoidable, the airbag count is six - dual front, dual side (thorax) and side head airbags for the driver and front passenger.

There are ISOFIX anchor points for baby capsules or child seats in the two rear positions.

The R8 is covered by Audi's three-year, unlimited kilometre warranty which not only falls behind in duration compared to mainstream brands but also its direct rival Mercedes-Benz which now has five-year, unlimited kilometre coverage.

Service intervals are every 12 months or 15,000km but unlike other Audi models there isn't a three-year or five-year plan available.

Porsche's three-year, unlimited-kilometre warranty is off the pace now, although the paint is covered for the same period, and a 12-year (unlimited km) anti-corrosion warranty is also included.

'Porsche Roadside Assist' provides 24/7 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer.

The main service interval is 12 months/15,000km but no capped-price servicing is available, with final costs determined at the dealer level (in line with variable labour rates by state or territory).
