Latest model
The second generation of R8 is, like its predecessor, available as either a coupe or a convertible, but exclusively as a 5.2-litre V10 model. Introduced at the end of 2015, the car was developed as a GT3 racing car before being put on sale as a road car.
In making a supercar, Audi has put itself up against one of the most enduring performance vehicles on the planet, the Porsche 911. This recently celebrated its 50th anniversary and it's no small task to beat it at the game it's been playing for so long. Other rivalries include the Ferrari 488 and McLaren 570S, while parallels will inevitably be drawn between the Audi and the other great, four-wheel drive, 600hp sports car with GT3 pedigree, the Nissan GT-R.
The second generation R8 is a sharper and more angular vehicle than the first but, like its predecessor, will often be mistaken for the smaller and cheaper Audi TT, at least until the characteristic side-blades – vertical pieces of contrasting bodywork behind the doors – come into view.
Unlike the first car, which had V8 and V10 power, the current car is V10 only, although a lower-output V6 turbo may be joining the line-up soon. It can also only be specified with a 7-speed automatic S-tronic gearbox – although the first generation was available with a manual, very few customers chose it.
The R8 is available in either regular V10 form or V10 Plus. The Plus model adds plenty of exterior decoration in carbon-fibre, including a fixed rear wing in place of the retracting one on the regular car, while also packing in almost 70hp more, which rockets the R8 past a 200mph top speed.
Value for money
It's by far the most expensive Audi you can buy, but even so the R8 doesn't represent poor value for money. Starting off at £123,330 (the convertible 'Spyder' is £132,020), the R8 is equipped with just about every conceivable modern amenity.
Standard gear includes Nappa leather seats (just two of them) which are electrically adjustable, with a memory function and heated. LED headlights are standard, as they should be since the R8 was the first production car in the world to use them, along with the Audi Virtual Cockpit.
This clever display system integrates entertainment (DAB is standard), phone interface (Bluetooth is also standard), satellite navigation (standard) and the selectable drive modes right into the instrument binnacle, along with the speedometer and rev counter.
While it's difficult to imagine what else you could add, the Plus model upgrades the suspension, brakes – to a carbon-ceramic system – and adds a few carbon-fibre trim pieces in addition to the power hike.
There is another one of Audi's famously expensive options lists though. You can add some novel laser headlights for £6,000, or have a diamond stitched headlining for £2,400 – but crucially it does show up a strange omission. Cruise control and a reverse parking camera are only available as option extras, even on the Plus model!
Running costs are generally high but not by the standards of most supercars. The 23-25mpg fuel economy ratings are just about achievable in the real world, servicing costs are expensive but the intervals are as long as any other Audi and the first-year VED rate and insurance are in the highest possible brackets.
Looks and image
While drivers of Audi's saloons and crossovers do not have the best of reputations, the Audi brand itself is relatively cool and the R8 may get something of a free pass as it's unusual and clearly a high-performance car but not quite as vulgar as a scarlet Ferrari or as unimaginative as a Porsche.
Audi has been working hard on cultivating a rebellious playboy image for the R8 in particular, with the convertible model of the car actually revealed through being the personal vehicle of Tony Stark/Iron Man in the Marvel films.
It's certainly a handsome car, and while many prefer the softer lines of the first version to the angular modern car, it has a lot of road presence and you're likely to draw more admiring glances than if you were in the equivalent Ferrari. It's going to be mistaken for its cheaper sibling, the Audi TT, quite a lot of the time and that may not be a bad thing – the TT itself is a good-looking vehicle and the R8 is less likely to be regarded as an ostentatious display of wealth as a result.
