RUF’s BTR conversion turned this lightweight 964 RS into a 400bhp outlier

One of just 290 Porsche 911 Carrera RS N/GTs, this Maritime Blue example became something far rarer still after a late-’90s visit to RUF added turbocharged power to an already uncompromising lightweight 911

As the wider world of driving is taken over by cars that do more and more to control themselves, niche manufacturers are offering models that deliver a true analogue experience.

1.Turbo-style ‘whale tail’ was a RUF addition

While that’s good news, it’s difficult to imagine any 21st century supercar being quite as ‘analogue’ as a Porsche 911/964 to Carrera RS N/GT specification – except for one that was subsequently treated to the laying on of hands at the legendary tuning house of RUF. Which is exactly the car on offer at RM Sotheby’s German summer sale.

2.Weight-saving features include thin glass and minimal door cards

Finished from new in spectacular Maritime Blue with black interior, it left the Stuttgart production line in June 1992 as one of just 290 911 RS N/GTs, and one of even fewer to include the Club Sport package which added Recaro seats, Schroth harnesses, extended fuel tank, thin glass, lightweight wiring, interior cut-off switch and a rollcage.

3. OZ Racing wheels look almost standard

The original German owner lived with it that way for seven years before sending the car to RUF for its famous BTR conversion – which adds a turbocharged 3.8 litre engine making more than 400bhp, a RUF six-speed manual gearbox, upgraded brakes and suspension, Turbo-style rear spoiler, RUF exhaust end pipes, OZ Racing wheels and countless other mods.

4.Interior remains to Club Sport MOO 3 specification, other than for the addition of RUF instruments

Surprisingly, however, the car was then stored for the best part of 25 years before being revived by its current owner within the past 12 months – an exercise said to have cost in excess of £25,000.

5.High capacity fuel tank gives extended range

Now on the button, fully operational and still with just 32,000 kilometres under its belt (around 20,000 miles), it’s begging to be driven in the way that RUF intended.

6.Maritime Blue paint is original, and favoured

Although the natural inclination to rip it around the Nürburgring at 200mph is probably best resisted.
