Las Vegas, America More than thirty years ago Volkswagen launched the GTI, a car that would kick start the hot hatch segment and revolutionise the concept of affordable and accessible high-performance motoring. Now comes the R GTI, launched in Las Vegas, a look forward into the future of compact car performance.

Few cars have enjoyed such an enduring run of success, and to honor the GTI’s rich past, Volkswagen has cast an eye on the GTI of tomorrow with the R GTI, a low-flying stealth machine developed by Volkswagen Chief Designer Derek Jenkins and his talented crew at the Volkswagen Design Center California, located in Santa Monica.

With its striking carbon fibre body panels, 4-passenger sports car interior, powerful turbocharged engine and competition-bred suspension, the R GTI is a stimulating fusion of style and dynamic excellence, fully modern in content and achievement yet staying true to such longstanding Volkswagen values as drivability, durability and utility.

The R GTI evolved from the stunning R Concept cars that stole the show at SEMA in 2005, and the R badge connects to the powerful R32, one of the most sophisticated and thrilling Volkswagens ever to come from the factory. However, unlike those R concept vehicles from last year, which showcased the extremes of performance-tuned Volkswagens, the R GTI represents a more streetable concept. Although the R GTI is a one-off and Volkswagen currently has no plan to put it into production, the dedicated enthusiast could gather many of the R GTI’s elements for a personal project, sourced from Volkswagen or from the thriving automotive aftermarket that has helped keep the GTI’s red badge blazing in the hearts of the world’s driving enthusiasts.

Jenkins approached the R GTI with the motorsport-inspired goal of “speed through lightness.” That is, reducing the car’s weight is as critical to improved performance as amplifying the engine’s output. In collaboration with the firm OSIR Design, hand-laid carbon fibre component experts, Jenkins replaced the stock GTI’s front fenders, hood, side rockers, and hatch door with carbon fibre panels developed by both OSIR and Jenkins’ in-house team.

Additional carbon fibre components are the lower front spoiler, front grille surround, rear rooftop spoiler and Jenkins-restyled rearview mirror housings, all in carbon fibre. Other distinctive exterior design touches include blacked-out front headlamp housings, R32 tail lamps with smoked lenses, R32-type central twin exhaust pipes with motorcycle-theme tips, a la Jenkins’ GX3 three-wheeler concept from 2005.

Reference to the GTI’s trademark hexagonal grille pattern is also seen in the R GTI’s specially constructed 19×9-inch aluminum alloy wheels, with lightness as a crucial contributor to reduced unsprung weight, and improved ride quality and cornering. Tucked within fenders designed for additional clearance, the beefier running gear includes Michelin Pilot Sport Cup ultra-high-performance radials, sized 265/30 R19. In track tests, the larger tyre footprint proved to be a valuable ally in transferring the engine’s prodigious 470Nm (340 ft-lb) of torque to the ground.

Despite being rolled straight out of the design studio on to the track, the R GTI pulled off an impressive zero to 60mph (0-96km/h) time of 4.8 seconds.

The chief contributor to the R GTI’s impressive performance is the turbocharged engine developed in conjunction with APR, one of the country’s leading aftermarket Volkswagen tuners. APR develops and sells high performance, and high performance only, leaving others to peddle air fresheners and floor mats. APR’s engineers and product developers are passionate about Volkswagen technology, and it shows in the quality and results of their contribution to the powertrain.

It all starts with Volkswagen’s 2.0-litre FSI turbocharged 4-cylinder powerplant, an award-winner for its unique combination of direct injection and turbocharging. APR also replaced the turbocharger with a larger Garrett ball-bearing unit with twice the flow capacity and pumped up the boost to 21 pounds per square inch (psi). All of the pressure-side plumbing was strengthened with silicon hosing and a large-diameter cast-aluminium, black powder-coated intake pipe feeds the big turbo the cool air it needs from the larger, front-mounted intercooler, delivering twice the stock air flow.

An Inconel exhaust manifold and an APR stainless steel exhaust system ensure efficient flow-through.

It’s a tidy, factory-like transformation, and the result is a whopping 375 horsepower (280kW), on 93 octane pump gas. If 100-octane race fuel is used, output rises to some 400 horsepower (298kW).

Harnessing that kind of power is as important as unleashing it, of course, and Jenkins was determined to retain the stock GTI’s driver-friendly demeanor. The clutch was upgraded to handle the increased torque, and a Quaife limited slip differential was installed to make the engine’s power flow more efficiently through the tyres. For the suspension Jenkins called on longtime experts HR Tuning to supply a system that would be reasonably comfortable when the R GTI was used as daily transportation but would also deliver crisp, precise handling when the road gets twisty or for weekend track days. Replacing the stock suspension is H&R’s RSS Club Sport system of coil-over shocks and springs, augmented by a pair of adjustable sway bars.

Ride height is reduced from 1.5 to 2.5 inches, but despite the ground-hugging stance and the Club Sport’s stiffer-than-stock settings, the suspension is compliant enough to comfortably dampen the rough spots in the road.

To bring deceleration into line with the improved acceleration, Jenkins selected Brembo brake components. Fitted at the front corners are Brembo’s four-piston aluminum alloy calipers, which squeeze Brembo two-piece floating cross-drilled discs with billet aluminum hats. The radial-mount design features a lightweight two-piece aluminum alloy body, quick-release pad system and sequentially sized pistons.

The front calipers have even been painted with the colors of the German flag. Inside the rear wheels are disc brakes fitted with drilled rotors.

The R GTI is an uncommon and visionary blend of design talent, factory technology and aftermarket innovation, and an enticing demonstration of why Volkswagen has been a favorite of automotive enthusiasts since the GTI first hit the scene 30 years ago. It also shows that the future of the hot hatch, as demonstrated by the R GTI, is already here.

Founded in 1955, Volkswagen of America, Inc. is headquartered in Auburn Hills, Michigan. It is a subsidiary of Volkswagen AG, headquartered in Wolfsburg, Germany. Volkswagen is one of the world’s largest producers of passenger cars and Europe’s largest automaker.

Volkswagen sells the Rabbit, New Beetle, New Beetle convertible, GTI, Jetta, GLI, Passat, Passat wagon, Eos, Touareg and Phaeton through more than 600 independent U.S. dealers.
