You may be aware of the 968 Turbo S, a super-limited production evolution of the Clubsport built and sold by Porsche's racing department under the leadership of Jurgen Barth and Gerd Schmid. Described as representing "the new GT class generation" and "destined for both racing activities and public street use" just 14 were built, identifiable by the two small NACA ducts on the bonnet and a bigger, adjustable rear wing.
Suffice it to say it's enough to make the astonishing £45K asked for the 944 Turbo we featured as our Hero and the ever hardening prices for 968 Clubsports seem trivial. Here's why it deserves to be held in such esteem...
Rarity will always arouse the attention of the collectors and add a zero or two to the price, but the Turbo RS has substance to back that up too. Rumours persist it was quietly canned when found to be quicker than contemporary 964 3.8 RSRs. This would certainly fit with the perception that Porsche was constantly having to manage the 'problem' of its junior transaxle cars being potentially quicker and easier to exploit than its rear-engined icon. There may be some truth in that but the reality would seem to be more people wanted to race 911s than they did 968s, no matter how much more effective the latter might prove to be.
For the Turbo S Porsche ditched the four-valve head used on the naturally-aspirated 968 Clubsport and instead fitted a two-valve one based on that used in the 944. Augmented by a single KKK compressor boosting at 1bar the oversquare 3.0-litre four-cylinder drove through a conventional six-speed manual with longer ratios and an aggressive limited-slip differential with a 75 per cent locking ratio on both power and overrun. Wheels and brakes came from the 911 Turbo S, ABS and power steering retained to help gentlemen drivers stay the course in endurance racing.
Ready for action
Designed in mind of the ADAC GT Cup the RS took things further still, coming as standard with a fully welded-in roll cage, plumbed in fire extinguisher system, 43-litre safety tank and six-point harnesses. Spring and damper rates were revised again and the wheels went up from 8J and 10J 18-inch items to 9.5J and 11J ones to contain an increase in power to a restricted 337hp. One car raced at Le Mans in 1994 but was forced to retire, the two others built for the ADAC GT series also seeing track action but never quite having the chance to deliver on the expectation suggested by the spec.
Not that you're in any doubt about that when you look around it in detail. It's got two seats but the passenger footwell is occupied by the boxes for the Motronic ECUs and opening the glovebox simply reveals the cross-brace from the roll cage rather than space to stash your Haribo. A bare gear knob - apparently from a 962 - sprouts from the centre tunnel and column stalk appropriated for manual overboost control and switch on the dash for the intercooler spray hint at the improvised, one-off nature of the build. It's all beautifully done though, fit and finish above average for a race car and indicative of the thoroughness Porsche's motorsport department puts into all its cars.
Given the nature of the car experience of it in action is limited to standing roadside to bag a few hurried snaps on a lane close to Gmund's showroom. And however effective a tool it might be, the uncultured blare it makes from its totally unsilenced exhaust perhaps offers a sense of why well-heeled privateers might have stuck with their RSRs. The sound is raw, brutal and pure race car, with no thought to pleasing harmonics. It's undeniably impressive though, the four-cylinder bark overlaid with a whistle of boost and crackle of overrun as the car runs to and fro for the camera. It's certainly appropriate to the car's intent too; this is a 968 built to do one thing and one thing only.
It carries it off with some style though. All the transaxle Porsches carry a lingering sense of unfulfilled promise forever in the shadow of the 911. But in this RS you get just a taste of the potential Barth and his colleagues knew was there but were never able to fully exploit. There's more than a hint of mischief about it too - the final flicked vees from a downtrodden subordinate after years of toeing the line to its elders and supposedly betters.
And the reflected glory of this rare, valuable and thrillingly raucous transaxle Porsche has the potential to finally drag its contemporaries out of the shadows and permit them to stand shoulder to shoulder with their rear-engined equivalents. That would be a legacy to celebrate and a fitting conclusion to this anniversary year.
