Range-topping Jaguar F-Type R Coupe

December 17, 2013

Jaguar F-Type R Coupe_01The top-of-the-range of the new Jaguar F-Type Coupe is the Jaguar F-Type R Coupe powered by Jaguar’s 5.0-litre supercharged petrol V8 all-aluminium engine. It delivers 550 hp and 680 Nm of torque making it possible for the Jaguar F-Type R Coupe to accelerate 0-60mph in 4.0-seconds and reach an electronically limited top speed of 186mph.

The R Coupé’s supercharged engine delivers not only exhilarating performance but also tremendous efficiency thanks to the technologies incorporated into it, including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT). The high-pressure die-cast lightweight aluminium block is stiffened with cast-iron liners and cross-bolted main bearing caps, providing refinement to match its power. The four-valve cylinder heads are constructed from high-grade, bespoke aluminium, between them sitting the Roots-type twin vortex supercharger fed by two intercoolers, which feature their own water-cooling circuit to reduce the temperature of the pressurised air, thereby optimising power and efficiency. Jaguar F-Type R Coupe’s CO2 emissions are 259 g/km.

The Jaguar F-Type R Coupe’s aerodynamic bodywork – gloss black front vanes beneath the shark gills and flat side sill extensions – aid its stability at the very high speeds of which it is capable. As standard the R Coupé’s window finishes are highlighted in bright anodised aluminium along the frames of the side glass, with the grille surround and side air vents in bright chrome, while the optional Black Pack adds gloss black window finishers, gloss black side power air vents and a gloss black grille surround. The front splitter, side power vents, door mirrors casings, bonnet power vents and engine cover are also available in carbon fibre.

20-inch Gyrodyne wheels in silver finish are standard on the Jaguar F-Type R Coupe, while a dark grey and diamond-turned version is optional. As on any F-Type specified with 20in wheels, the F-Type R Coupe is available with optional ultra-high performance tyres which, with a unique tread pattern, offer additional steering precision, and increased levels of grip for the enthusiast driver.

The Jaguar F-Type R Coupe is fitted with Jaguar’s Adaptive Dynamics system that actively controls vertical body movement, roll and pitch rates. The system continuously monitors driver inputs and the attitude of the car on the road, adjusting damper rates accordingly up to 500 times a second to optimise stability. For the Jaguar F-Type R, the Adaptive Dynamics controlling software has a bespoke tune, working in tandem with revised spring rates all-round to deliver consistent, progressive and exploitable handling. Spring rates are increased by 4.3% at the front and 3.7% at the rear compared to F-Type V8 S Convertible.

Engaging Dynamic mode delivers an even more focused driving experience thanks to enhanced body control through firmer damping rates, increased steering weighting, faster gear changes and sharper throttle response. In the Jaguar F-Type R Coupe, Dynamic mode is configurable as standard via the central 8in touchscreen, allowing the driver to select and save settings according to their preference.

In addition to the fundamental suspension tune changes, the F-Type R Coupe features a new second-generation Electronic Active Differential which, for the first time on a Jaguar, works in conjunction with Torque Vectoring by braking. Together, the two systems ensure agility at all speeds and exploitable on-the-limit handling. The Jaguar F-Type R Coupé’s Electronic Active Differential (EAD) builds on the progressive handling advantages of a mechanical limited-slip differential by intelligently controlling the amount of driveline torque fed to each wheel. The EAD utilises an electric motor which operates a multiplate clutch; by rapidly and continuously analysing a range of electronic inputs it is able to immediately vary torque transfer to each driven wheel to maximise traction in any condition.

Torque Vectoring by braking – a standard feature on F-Type R Coupe – applies finely metered braking torque individually to the inner wheels as necessary, helping to turn the car into corners more precisely. Using the F-Type R Coupe’s array of electronic sensors, the Torque Vectoring system determines when corner entry speed may induce understeer. It then calculates the level of brake force needed to correct the car’s direction and, via the ABS system, applies that precise braking force to individual inner wheels as necessary. Torque Vectoring by braking works at a subtle level, both correctively and predictively, finely adjusting the trajectory of the F-Type R Coupé for optimal handling.

The Jaguar F-Type R’s EAD and Torque Vectoring by braking systems – which work together with the car’s Dynamic Stability Control system – complement each other to optimise traction, cornering ability and, most importantly, to maximise steering feel and agility. Torque Vectoring by braking works to fine-tune trajectory around a corner, and as the car is pushed further to its limits, there is a natural, seamless transition to EAD. As a result, the use of available grip is always optimised, enabling the Jaguar F-Type R Coupe to carry more speed both into, through and out of corners, while delivering precision handling during high-speed manoeuvres.

The F-Type R Coupe uses Jaguar’s Super Performance braking system as standard. This system features 380mm front and 376mm rear discs – with red or black painted calipers. Brake cooling is optimised via under-body channelling of air, the air-flow being derived through the use of Computational Fluid Dynamics analysis. The R Coupe is also available with optional Carbon Ceramic Matrix (CCM) brakes which offer consistent performance and excellent fade resistance even during extreme performance driving conditions, while retaining the precise pedal feel of the standard system and extending disc life in everyday driving use.

The Jaguar F-Type R Coupe’s switchable Active Sports Exhaust system – with its signature quad, outboard-mounted tailpipes – takes the aural excitement delivered by the 550 hp engine to new levels. It offers an authentic, rich sound, developing to a howling crescendo as the upper limits of the rev range are reached. The system uses electronically controlled bypass valves in the rear section of the exhaust which are mapped to open according to a range of parameters, effectively altering the exhaust gas routing into a free-flowing straight-through arrangement to both reduce back pressure and enhance sound quality. Selecting Dynamic mode also opens the bypass valves, an optional override button enabling further driver control of the system.
