Volkswagen Golf R Cabriolet
For at least a decade now the "R" model identifier has referred to the most powerful Volkswagen cars in the compact class. So far, they have always been cars with solid steel roofs and some with sliding sunroofs. Now, Volkswagen is introducing an open-top R model for the first time: the new VW Golf R Cabriolet. This sports car will be delivered to customers by spring 2013; and these early purchasers will be driving the most powerful and fastest Golf Cabriolet cars ever. Tremendous propulsive power is generated by a 2.0-litre turbo engine with direct petrol injection (TSI) that develops 195 kW /265 PS. Maximum torque is just as important to dynamic performance: from a low 2,500 rpm, the crankshaft of the TSI thrusts 350 Nm of torque to the standard 6-speed dual clutch gearbox (DSG). This high torque level remains constant up to 5,000 rpm: an impressive torque characteristic and highly agile handling properties are key ingredients of the new Golf R Cabriolet.
6.4 seconds and 8.2 litre fuel consumption
Drivers who make use of the car's full power potential can accelerate the open-top Golf to 100 km/h in just 6.4 seconds. The car's top speed is electronically limited to 250 km/h. The 6-speed DSG is an ideal partner here, shifting quickly and without any interruptions in power transfer. Since the open-top sports car already has lots of power at the lowest revs, and the engine very seldom needs to rev fast, fuel consumption is lower than would be expected for such a high powered car: 8.2 l/100 km (equivalent to 190 g/km CO2).
As the new range-topping Golf Cabriolet model, in additional to offering standard features such as rollover protection, this model will also feature bi-xenon headlights, LED daytime running lights, LED rear lights, 18-inch alloy wheels, sport seats (front), leather upholstery, automatic climate control, audio system with CD player, sport chassis and bumpers with a unique motorsport design. However, another key feature of this Golf Cabriolet is its soft top, which ensures a refined drive even when driving at the highest of speeds. It has a standard electro-hydraulic opening mechanism that opens the roof in 9.0 seconds. The exceptionally sporty and well-equipped Volkswagen Golf R Cabriolet will cost 43,325 euros in its domestic market of Germany.
133.6 PS per litre displacement and 6-speed DSG
In the new Volkswagen Golf R Cabriolet, the turbocharger of the very flexible EA113 series direct petrol injection engine offers great variability right up to the highest power ranges. As already mentioned, the engine produces a strong 265 PS which is available from 6,000 rpm. The 1,984 cc four-cylinder engine's power-to-displacement ratio is a respectable 98.3 kW or 133.6 PS per litre. This makes the TSI engine very responsive. The in-line four cylinder engine builds up its impressive propulsive power via a turbocharger (up to 1.2 bar charge pressure) and an intercooler. The pistons of the four cylinder were equipped with reinforced bolts compared to the less powerful TSI versions. Engine designers also made the connecting rods stronger to transfer the high torque reliably to the crankshaft. Last but not least, the cylinder block was also reinforced to handle the higher engine forces. The TSI's power is transferred to the front wheels via a standard 6-speed DSG transmission.
With regard to its "R" running gear, the VW Golf R Cabriolet retains the sophisticated suspension layout of other open-top Golf models. This means familiar suspension struts with coil springs and telescoping dampers at the front and multi-link suspension at the rear to ensure that the electronic stabilisation programme seldom needs to intervene. The ride height for the R model was lowered by 25 mm, however, and the springs, dampers and stabilisers were given a sporty tuning in keeping with the vehicle's character.
The DCC adaptive chassis control system is available as an option; its behaviour has also however been synchronised to match the character of the Volkswagen Golf R Cabriolet. The system continually adapts chassis damping to the road and driving situation. Along with the standard "Normal" mode, the driver may also manually activate a "Sport" or "Comfort" damper control setting.
The brake system was modified for the higher driving performance of the Golf R Cabriolet as well. Instead of a 16-inch system, a 17-inch system is used which features internally ventilated discs and "R"-specific brake callipers painted glossy black with an "R" logo at all four wheels. The front discs have a diameter of 345 mm, the rear discs 310 mm. The steering system with electromechanical assist was also given a sportier characteristic. When the VW Golf R Cabriolet is ordered with the DCC vehicle dynamics control system, the steering assist has a modified characteristic tuned to the selected mode ("Sport", "Normal", "Comfort").
Standard wheels on the Volkswagen Golf R Cabriolet are 18-inch "Talladega" type alloy wheels in "Sterling Silver" colour with 225/40 size tyres. The same type of wheel can be ordered in an optional 19-inch version with 235/35 tyres. The 19-inch wheels can also be ordered in "Black".
The soft top consists of a linkage, an interior roofliner, an insulating filler throughout and an exterior cover. Perfection in everyday practicality: the development team designed the joints of the longitudinal seams of the exterior cover fabrics (centre panel and two side panels) so that they serve as an additional drip rail. Perfection in aerodynamics: mounted between the longitudinal frames of the top linkage are a total of 4 roof cross bows and the so-called front roof bow (the first large transverse element behind the windscreen frame). The soft top is joined to the roof bows by fabric retention strips with screw fasteners. Consequently, even at higher speeds, the fabric roof holds its form and that has a positive effect on aerodynamics. To ensure a good view behind the car, the top's heated rear glass window was designed to be especially large for a convertible.
The roof system of the VW Golf R Cabriolet was adopted 1:1 from other models in the series. The standard electrohydraulically-operated soft top is activated from a central switch on the centre console. The top can even be opened (9.0 seconds) or closed (11.0 seconds) while driving at speeds up to 30 km/h. Two hydraulic pumps activated by a central switch generate the required pressure. Measures were even taken in this area to ensure that as little noise as possible is produced; the hydraulic unit is therefore enclosed by insulation. The soft top of the Golf Cabriolet is unlatched and latched fully automatically by an electromechanical locking system.
Within just a quarter of a second of the vehicle exceeding a predefined transverse acceleration or tilt angle, the cabriolet's rollover protection system shoots up behind the rear headrests. The system's two rollover modules consist of one fixed aluminium profile and one moveable aluminium profile within it that is pretensioned by a spring. The inner profile is held in its rest position by a magnetic switch or solenoid. When triggered by the airbag controller in reaction to an impending rollover, the solenoid opens a holding detent and releases the inner profile. While it shoots up, a support detent runs over a toothed track mounted to the inner profile and prevents the inner profile from dropping back down.
The construction of the two deployable modules was made significantly more compact, and so - despite the deployable rollover protection - it became possible to implement a load-through provision similar to that in the new Beetle Cabriolet with a width of 526 mm and a height of 381 mm as well as folding rear backrests.
All Golf cabriolets offer maximum all-round safety thanks to its rollover protection system, a reinforced windscreen frame and numerous other structural modifications (underbody, side panels, crossmembers, doors). Its numerous reinforcements also give the 4,266 mm long, 1,782 mm wide and (top up) 1,405 mm high Golf R Cabriolet extremely high torsional rigidity values. In front, the cabriolet has an engine enclosure made of aluminium, and together with its mounting brackets this increases rigidity. In addition, the engine mount acts as a vibration damper to reduce noise at the front of the car. On each side of the car, two lateral reinforcements in the sill area and two diagonal braces, front and rear, as well as the reinforced rear subframe joint lead to further gains in rigidity and a significant reduction in resonant body vibrations. What is referred to as the coefficient of static torsional rigidity reaches a value of over 13,500 Newton metres per degree; the first resonant torsional frequency lies above 17.5 Hz - first-class for a convertible.
The protective systems are completed by reinforcements in the doors and standard front and side head-thorax airbags. The latter are specially designed for a cabriolet, since it is of course impossible to mount side head airbags in the roof area. The head-thorax airbags integrated in the lateral sections of the seatbacks therefore deploy next to the driver and front passenger over the entire interior height of the Golf Cabriolet. A standard knee airbag has also been incorporated on the driver's side. In conjunction with the safety belt, this airbag absorbs energy from the pelvic area and the legs, which leads to reduced occupant loading.
All versions of the Golf Cabriolet offer standard features such as a soft top that opens and closes fully automatically, automatic rollover protection system; electronic stabilisation programme and air conditioning. The Volkswagen Golf R Cabriolet also offers numerous extra features as standard.
