Hardcore 518bhp A3 concept revealed ahead of Wörthersee show, with parts of it previewing the upcoming RS3 saloon

Audi has revealed a spectacular new 518bhp version of its recently introduced A3 saloon that is set to underpin its display at this year’s Wörthersee fan meet in Austria later this month.

The powered-up four-door, which goes under the name A3 Clubsport Quattro, is officially described as a concept. Audi development boss Ulrich Hackenberg has however hinted that elements of the new car will be seen on future production models, including an upcoming RS3 saloon slated for introduction in 2015.

At the heart of the Audi’s latest high-powered concept car is a heavily reworked version of the German manufacturer's turbocharged 2.5-litre direct-injection petrol engine – as fitted to the RS3 and TT RS in recent years. The five-cylinder unit has been extensively redeveloped to achieve previously unattained factory levels of power and torque.

Included among the modifications confirmed by Hackenberg is a larger turbocharger running 1.5bar of nominal boost pressure, a more efficient air-to-air intercooler and larger intake and exhaust manifolds.

Power has increased by a whopping 183bhp over the standard specification engine, rising from 335bhp to 518bhp. This provides Audi’s traditional five-cylinder unit with a stunning specific output of 207bhp per litre. Torque is also up by 112lb ft, swelling to a peak of 443lb ft between 2300rpm and 6000rpm.

With a claimed kerb weight of 1527kg, the new Audi concept boasts a power-to-weight ratio of 339bhp per tonne – exactly the same figure quoted for Audi’s range topping 542bhp 5.2-litre V10-powered Audi R8 V10 Plus.

The prodigious reserves are channelled to all four wheels via a beefed-up version of Audi’s seven-speed S-tronic dual clutch automatic gearbox featuring a unique final drive and integral launch control function. It works with an electro-hydraulic Haldex-style multi-plate clutch four-wheel drive system described as being "suitably modified" to handle the additional torque loading.

Official performance claims suggest the A3 Clubsport quattro accelerates from 0-62mph in just 3.6sec and hits a top speed of 193mph, some 1.3sec and 38mph faster than Audi quotes for the 296bhp turbocharged 2.0-litre four-cylinder-powered S3 saloon.

Among the changes brought to the A3’s standard MacPherson strut front and multi-link rear suspension is a 10mm reduction in nominal ride height and the adoption of firmer springs and dampers. In keeping with its extreme nature, the one-off concept also receives towering 21-inch wheels shod with ultra-low-profile 275/25 tyres.

The big wheels house brakes boasting 370mm carbon-ceramic discs and multi-pot aluminium calipers at each corner. They operate in combination with an air brake function integrated into the spoiler housed in the rear edge of the boot lid. Electronically actuated, it is programmed to work at braking speeds above 155mph and is claimed to reduce stopping distances by up to 12 metres by allowing the braking system to allocate more braking power to the rear axle due to the increased downforce it generates.

Car review

Third-gen Audi A3 gets a mild facelift, more equipment, some new engines and a new hot model - but is it the cream of the premium hatch crop?

Back to top

Building on the appearance of the standard S3, the A3 Clubsport Quattro receives a vivid Magnetic Blue paint scheme, a heavily restyled front bumper featuring a grille with a brushed aluminium frame and a high-gloss honeycomb insert, as well as sizeable air ducts, an integral carbonfibre splitter, distinctive LED headlights and widened front fenders.

Further back, there are carbonfibre sills underneath the doors, smaller mirror housings, widened rear arches and a deeper rear bumper housing two sizeable round chromed tailpipes and a large diffuser. The standard fuel filler flap has also been replaced by a more stylish aluminium element.

Design details

I like the concept as a whole, but there some individual details that for me stand out; the rear diffuser is especially impressive, as are the trademark blistered wheel arches and subltly extended rear lip spoiler. As impressive as the performance figures are, I think I may be growing out of the whole 'lets make the most powerful' thing and would just appreciate the ride and handling.

Back to the subject...

...of this hideously overpowered Impreza/Evo successor. What's the bleeding point? That Audi can make a small saloon with Lambo horsepower stay on the road? It's the answer to a question nobody asked. And while I'm on my high horse: stop the ridiculous power struggle between carmakers NOW.

i would put it down to

i would put it down to assumptions / ignorance as well. When buying my cars, I generally find that I know more about the cars at main dealerships than their salesmen. For example, on a Volvo test drive, I couldnt believe that I had to explain some of the safety features on a S60 to the main dealer salesman. Their staff in servicing also dont know more than required to carry out their jobs. For example a technician at a VW main dealers thought a failing fuel pump in my Golf was feedback through the speakers... a problem a fully trained "master technician" sussed out in a split second. When I worked in a main dealership during my student days, I found that most staff didnt care about cars in the slightest. They could have been selling toilet paper for all the passion they had. Their knowledge of the products reflected this. I tried explaining to one sales woman how an engine worked. She just looked stupified... knowing nothing of the technical aspects didn't stop her selling cars though. She really knew how to look after customers and was pretty successful.
