Ruf`s new Turbo Florio unites the Targa with
HEAT SHIELD Florio NEWch.qxp:PW Template 2/18/16 4:17 PM Page 48 Ruf’s new Turbo Florio unites the Targa with forced induction – and pays homage to the great Sicilian road race where Porsche cut its teeth H Words: Johnny Tipler Photography: Antony Fraser urtling up to Granza hairpin, the tifosi line the outside of the corner three deep, waving and cheering, with almost as many lining the inside of the turn as the blue and orange 908 Spyder sweeps into the halfhidden apex, chutzpah and bravura rendering them oblivious to the dangers from wayward sports-racing and GT cars. It’s a sight that frequently greeted Brian Redman en route to his Targa Florio win with Jo Siffert in 1970, though mercifully absent from our recent Bavarian backroad blitz in the Ruf Turbo Florio. The world’s oldest motor race, the Targa Florio was a round of the World Sportscar Championship from 1955 to 1973, and it’s a scenario typical of the event’s halcyon days when Porsche ruled the roost on the 72-mile mountain course. With 11 outright victories and numerous podiums and class wins during a 17-year period spanning 1956 and 1973, the Zuffenhausen marque celebrated its successes by identifying its top-off 911 variants as the Targa from 1967. And it’s also commemorated in one of the latest offerings from the Bavarian tuning and manufacturing wizards Ruf Automobile, which is why we’re at Pfaffenhausen to see what makes 48 911 & PORSCHE WORLD Alois Ruf’s Targa substantially different to the standard factory 991 version. Well, for starters, it uses the turbocharged Mezger-based engine, twin turbos lifting power output to up to 700bhp against the no-slouch 400bhp of the standard model, and what’s more they’ll build it in two- and four-wheel drive format as required. And with overt Ruf styling modifications it is a distinctive variation on the Targa theme. Taking the Targa name and applying it to the removable roof version of the 911 – the targa shield doubling as the lid of the car – the topless format has been a key model in the line-up since 1967 with the softwindow version, through to the ingenious glass-roofed 993, 996 gen 2 and 997, and then as the distinctive Targa roll hoop incarnation with the 991 in 2014. The current car emulates the Boxster’s electronic decapotable roof mechanism to lift the ceiling panel over the heads of the occupants and setting it down in the well at the rear of the cockpit, leaving roll hoop and rear screen in place, just like the original 911 Targas. Alois describes the thinking behind his new car: ‘The idea of the Turbo Florio was to combine the new technology of the Targa with the drivetrain of the Turbo 991, adding a Florio NEWch.qxp:PW Template 2/18/16 4:18 PM Page 49 RUF TURBO FLORIO 911 & PORSCHE WORLD 49 Florio NEWch.qxp:PW Template 2/18/16 4:18 PM Page 50 RUF TURBO FLORIO A subtle ducktail wing and reworked rear apron define the Ruf look. The turbo cooling ducts can just be seen on the top of the rear arches 50 touch of Ruf, which is the extra performance of the 3.8 engine that delivers 630bhp. And it’s also about the stance of the car when you look at the front end, so we have a different appearance and a sportier vehicle. One of our special touches is the signature Ruf air intake, which is very subtle, and that makes it a unique car.’ No one is more conscious of the status of his marque in the historical framework, and since Alois grew up with Porsches at his father’s garage he’s intimately acquainted with their race history. ‘The name came from the Targa Florio, because Vincenzo Florio was the founder of that race, and we thought it would be good if his name could also be on a car named after him. We were thinking of his inspiration, and how brave he was to bring the first automobile to Sicily, and so we thought that this open-top car that’s essentially designed for good weather driving, we should give it his name. I don’t think that’s ever happened before. It’s a unique car for the individualist 911 & PORSCHE WORLD who likes to have a Targa-top car combined with turbo power, driving with the double-clutch gearbox, and lovely flat handling.’ Though Porsche never raced a works 911 Turbo in the Targa Florio, a couple of privately-entered 930s placed 4th and 8th in the swansong 1976 race, legitimising the Ruf Turbo Florio connection, if any justification were necessary. Though it’s finished in a familiar Porsche sapphire blue, the Ruf components on the Targa contrive to differentiate it markedly from the factory model, and I’ll highlight those in a moment. Because, perhaps most strikingly, it’s the air intakes in the topsides of the rear wheelarches, tapering off subtly into the rear three-quarter panel to the sides of the rear window, which provide the most surprising visual departure from standard, plunging deep into the recesses of the rear wings and optimised to supply the intercoolers without being affected by the heat dissipating from the engine and the brake “ discs. ‘The design and creation has all been all done in-house, together with an external freelance designer, so we’re using the original part from the Targa, cutting the shape of the holes and then welding in extra metal that’s shaped in detail to make this design. The decreasing size of the duct accelerates the air to provide a better flow to the intercooler, so we’re using the shortest, most direct way to the intercooler here, behind the wheel, instead of ahead of the wheel.’ Vast, mesh clad ducts behind the wheelarches each side of the rear apron help vent hot air from intercoolers and brakes. ‘These are basically just the exits for the air that has gone through the intercooler, and this mesh is really a visual thing so that you don’t see the insides, but they also protect the intercoolers from stones thrown up by the tyres.’ The ducktail rear spoiler is another obvious addition: ‘There’s no movement in the three vanes on the engine lid because the turbochargers are sucking the air in so It’s a unique car for the individualist who likes to have a targatop car combined with turbo power ” Florio NEWch.qxp:PW Template Ruf design 20in alloys are to Ruf as the Fuchs design is to Porsche – a defining feature. Rear diffuser is more show than go, but the neat ducktail wing provides all the downforce that’s required 52 2/18/16 4:18 PM Page 52 you don’t need to optimise that by lifting this up, and as regards the aerodynamics we get the maximum downforce we need with the ducktail because the airflow pours over the low angled surface of the rear window. Anyway, we don’t need so much downforce at the back because the car would become too light at the front.’ The exhaust tailpipes protrude from either side of the carbon-fibre diffuser – a conceit that serves more aesthetic than practical purpose though it is in keeping with the turbo iconography, likewise the carbon-fibre door mirrors. ‘The diffuser is not going underneath the complete body, so it doesn’t have a huge function because the downforce from the ducktail is already more than enough, so we really didn’t want to have more downforce with the diffuser.’ The wheels are hunky Ruf five-spoke alloys, shod with 325/25 ZR 20s on the rear and 255/30 ZR 20s on the front. The carbon front lid sports “ 911 & PORSCHE WORLD the Ruf logo, as do the door-shut kickplates, while the engine lid displays the subtle Turbo Florio signature. The instruments are inscribed with the Ruf legend, and the logo is embossed in the headrests, which is a nice touch of class. And then the front panel. Really, this is the car’s signature, if you discount the Targa roll-hoop; starting with those vast air intakes and corresponding slits beneath the small light clusters, central gaping maw, and the twin semi-circular outlet slats in the upper surface of the front panel; and the sculpted upward aerodynamic slashes on either corner, echoes of the deep carbon-fibre front splitter traversing the leading edge. It’s an exquisite artwork in the chunky, no messing, Giacometti style. What about the Ruf power hike, though? I’m with Marcel Groos, Alois’s son, and he describes the mechanical DNA of the Florio: ‘We started with a 991 Targa chassis and We started with a 991 Targa chassis and fitted our Tt35 twin-turbo engine fitted our Rt35 twin-turbo engine with a double clutch transmission, so we can achieve up to 700bhp. So that’s the drivetrain, and then we have designed these air intakes in order to supply enough air to the intercoolers.’ Handling and stopping have also been addressed in respect of the extra horses. ‘The Turbo Florio brakes are carbon ceramic, with 380cm discs on the front and 380cm discs at the rear. The suspension is a coil-over system that we’ve developed and set up especially for this car. It also has the hydraulic lift system as a standard feature so you can always push the button and the car lifts up and lowers automatically when you go more than 45mph.’ Indeed, the button in question is mounted in the centre console just ahead of the armrest; flip a lid to reveal a Ruf logo’d switch, which I press, and the nose rises up, enabling me to negotiate rough ground or sleeping ”
