Anybody who has seen that picture of Alfa Romeo’s 164 Procar – the well-known one in profile, entrance and rear bodywork eliminated – already understands this new Ruf. Solely as soon as the pores and skin was indifferent from Alfa’s V10 silhouette racer of 1988 was it apparent that the factor had nearly nothing in widespread with the 164 household saloon, and it’s the same story with the Ruf SCR.

Regardless of the aesthetic, it shares little with an outdated Porsche 911. How little? For one factor, it’s constructed, McLaren-style, round an 88kg composite tub of Ruf’s personal making. For one more, the suspension is by double wishbones with pushrod actuation. There was just one official 911 with each these parts and that’s the 911 GT1 with which Porsche received at Le Mans in 1988.

The Ruf’s deceptively small and low-slung physique, together with its X-rated hips and dinky ducktail spoiler, can be full carbonfibre, which is one thing no Zuffenhausen 911 has ever had.

So whereas it appears to be like like a 911, albeit yet another imaginatively conceived than most vehicles in Ruf’s lengthy again catalogue, the SCR is categorically no such factor. What it’s as a substitute is Alois Ruf Jr’s imaginative and prescient of what the last word rear-engined efficiency automobile would possibly seem like. Made in Pfaffenhausen, in fact, and now on sale for £770,000.

That is an costly automobile, however the depth of improvement engineering is kind of one thing. Plus, with Singer’s 964-based creations routinely promoting for seven figures, you might argue the SCR’s asking value merely displays actuality on this a part of the market.

A lot of the work has targeted on the SCR’s crown jewel, and the 8700rpm flat six is the place this automobile will get closest to true Porscheness. In its tail sits an engine whose block is forged in-house however relies on the three.6-litre Mezger-designed unit from the 997 GT3. After trial and enchancment,it was felt the perfect mixture of firepower, character and cost-effectiveness was achieved with precisely 4 litres of swept quantity. Go a lot past that and Ruf claims the engine would wish monstrously aggressive camshafts and a race ECU to make the additional displacement depend. All that may additionally add to the prices, by no means thoughts the implications for day-to-day usability.

Sitting atop the 4.0-litre block, the cylinder heads for this massively oversquare engine are Ruf-specific, similar to the titanium rods and solid pistons, though the crankshaft is similar racing crank discovered within the outdated 997 RSR. Altogether, the engine is nice for 503bhp, which in 2022 doesn’t appear all that a lot (the BMW M3 Competitors has simply as a lot, for goodness sake), however two issues want stressing. First, the SCR is of course aspirated, and 503bhp is nearly what anyone anyplace can right this moment reliably claw from six horizontally opposed cylinders with out resorting to pressured induction (the SCR’s twin-turbo sister, the tribute-to-the-Yellowbird CTR Anniversary, makes 700bhp with relative ease). Second, even with fluids, the automobile weighs simply 1250kg. On power-to-weight ratio, it due to this fact wipes the ground with not solely the M3 Competitors but additionally the latest 911 GT3 RS.

Downstream of the engine, then, sits a six-speed guide gearbox, custom-built for Ruf by ZF. It feeds torque to a mechanical limited-slip differential and 305-section Goodyear Eagle F1 Supersport R rear tyres wrapped round centre-lock 19in wheels. The wheels are easy solid objects, and unsprung mass is additional decreased by carbon-ceramic brake discs.
