V8 DTM QUATTRO Stunning race replica for the road
Audi Sport has produced many iconic racing cars over the years. But perhaps one of the most successful and best-loved, is the V8 DTM quattro. Based on the road-going #Audi-V8-Saloon
, the DTM ( #Deutschen-Tourenwagen-Meisterschaft
) cars were comprehensively re-engineered for the track. With strict #DTM
regulations outlawing turbochargers, Audi’s mighty five-pot was sidelined. So #Audi-Sport
turned their attention to an altogether different beast.
The range-topping V8 saloon featured a naturally-aspirated 3.6-litre unit. With power boosted from 250hp, in factory tune, to an initial 420hp, the all-alloy V8 certainly had the credentials to challenge the best from Mercedes and BMW – although many thought the large V8 Audi would struggle against the smaller M3 and 190 Cosworth. Indeed with an extra 300kg to lug around, you’d expect the Audi to be outclassed by its lightweight competition. However, the combination of lusty V8, #4WD
and with Hans- Joachim Stuck and Frank Biela at the wheel, the big saloon made the podium in its debut race and went on to give Audi the Manufacturers’ title in 1990 and 1991 The following season there was a flurry of complaints about Audi’s quattro system, which led to weight penalties being imposed. In response, Audi’s engineers tweaked the engine, which ultimately led to the modifications deemed illegal and Audi’s complete withdrawal from the series.
So the life of the V8 quattro racer may have been ephemeral, but it remains one of the most talked about cars Audi has produced. It was with this in mind that serial Audi tuner, Roni Collin, created this road-going replica.
You may recall Roni from issue 018, where he showed us the world’s first RS6-inspired S6 C7 saloon, complete with genuine RS6 front end, wings and a host of custom fabrication. This V8 DTM is another of his projects that has been many years in the making.
The previous owner had intended to build a DTM replica, but had never really got going with it. Roni decided he would finish the job – although his would be fully road-legal and have a much better stance.
The work took over five years in total, but this was in between other projects and Roni’s hectic work schedule (as a serial entrepreneur, he’s always busy.) “I’ve always been more excited by the process of the build than the end result. I don’t participate on the actual builds that much, but I enjoy the planning, getting all the parts, and designing the unique look of the car,” he says.
Creating something bespoke like this is never an easy undertaking, but as Roni explains: “Luckily I have Björn who never says no to my crazy projects. Not even then when I bring him a brand new car to be cut in pieces and replaced with another OEM look parts welded back in.”
In the case of the V8 DTM, the main aim was to make it look like an original racer, so the interior was stripped out and a comprehensive roll cage fitted. All unnecessary pieces of trim were removed and a single bucket seat with harnesses added. But that’s not all – there’s a flocked dash, a custom centre console housing switches, carbon fibre door panels and a long-reach gear lever. It really does have a motorsport feel to it – you almost expect Hans Stuck to clamber out of it.
When it came to the exterior, Roni insisted on full period correct motorsport livery. Everything looks as it should, complete with sponsors’ logos. Even the cross-spoke split-rim wheels are similar to the BBS items on the original (although Roni has since fitted some genuine BBS items).
To get the big saloon sitting nice and low like a DTM car, a set of KW coilovers have been fitted. The 8.5 and 9.5x18in Rotiform alloys sit perfectly in the arches, wrapped in Pirelli road rubber.
Under the bonnet, the 3.6-litre V8 is currently in factory trim and makes about 250hp. But Roni has plans for a tuned engine, so this faithful replica will, at some point, also have the performance to match the looks.

THE V8 DTM RACER
In the hands of #Hans-Joachim-Stuck
) and Frank Biela, the #V8
was very successful, beating the much lighter Mercedes 190 Cosworths and BMW M3s to win the title for #Audi
. The big Audi initially featured a 420hp all-alloy V8, but, as weight penalties were imposed to counter the supposed advantage of quattro, the engineers developed a modified flat-plane crank, taking power up to 460hp. This glorious V8 would rev to a heady 9,500rpm. Unfortunately, in #1992
the new crank was deemed illegal and Audi withdrew from the series. Check out YouTube to see these amazing cars in action.
