2014 Jaguar F-Type
The amazing Jaguar F-Type finally comes out of shadows at the Paris motorshow, showing us its gorgeous face, it’s perfect body, and it’s big heart.
The 2014 Jaguar F-Type combines low vehicle weight (starting at 3,521 pounds), high power (340hp, 380hp and 495hp versions) and superb aerodynamics to achieve a pure sports car experience, yet with Jaguar elegance and luxury. A true two-seat sports car, the all-new Jaguar F-Type is equipped with a modern, lightweight soft top that, when lowered, serves as its own tonneau cover. This not only provides a weight savings, but also improves packaging and contributes to the car’s low center of gravity for greater agility. The top can be fully raised or lowered in just 12 seconds at speeds of up to 30 mph.
Then there is the engines. You get a supercharged V6 with either 340 or 380 horsepower, and a supercharged V8 with 495 horsepower. They also come with active exhausts for maximum driving pleasure. It really is a flawless sports car.
Details in Jag press release below:
The F-Type showcases the new supercharged Jaguar engines, a 3-liter supercharged V6 in 340hp and 380hp states of tune and the 5-liter supercharged V8 in the Jaguar F-Type V8 S with 495hp and 460 ft-lbs of torque. All are equipped with the new Intelligent Stop/Start system to enhance fuel economy under certain driving conditions.
The 340hp version of the supercharged V6, which debuted in the 2013 XJ and XF sedans, produces 332 ft-lbs of torque at 3,500-5,500 rpm. The 380hp version, exclusive to the F-Type, produces 339 ft-lbs of torque at 3,500-5,500 rpm. The V8 produces an even broader torque curve, with 460 ft-lbs produced over the 2,500-5,500 rpm range.
The 340hp V6 model can accelerate from zero-to-60 mph in 5.1 seconds (0-100km/h in 5.3 seconds). The 380hp S model lowers that to 4.8 seconds (0-100km/h in 4.9 seconds), and the V8 S can hit 60 mph from rest in just 4.2 seconds (0-100km/h in 4.9 seconds). Electronically limited maximum track speeds are 161 mph (260 km/h), 171 mph (275 km/h) and 186 mph (300 km/h), respectively, for the V6, V6 S and V8 S models.
In addition to rapid zero-to-60 acceleration, the new Jaguar supercharged engines give the F-Type outstanding merging and passing performance. The 340hp V6 model will go from 50 to 75 mph in just 3.3 seconds; the 380hp S version in 3.1 and the V8 S model in 2.5 seconds.
Based on the Jaguar 5-liter V8 engine, the 3-liter V6 shares its all-alloy construction. The lightweight die-cast aluminum block is stiffened with cross-bolted main bearing caps, increasing rigidity and refinement. A system of counter-rotating front and rear balancer weights help give the new supercharged V6 the smoothness and refinement characteristics of the V8 on which it is based.
The supercharged V6 and V8 engines combine high compression, direct fuel injection, dual independent variable cam timing (DIVCT) and a supercharger to deliver their high levels of performance and efficiency. A twin vortex supercharger is mounted in the engine’s “V”, and a water-cooled intercooler reduces the temperature of the intake air to optimize power and efficiency. The supercharged V6 uses a higher compression ratio than the V8, 10.5:1 vs. 9.5:1.
In both the V6 and V8, the aluminum cylinder heads package an innovative valve control system. The dual independent variable cam timing (DIVCT) system is activated by the positive and negative torques generated by the movement of the intake and exhaust valves, allowing exceptionally quick actuation rates of more than 150 degrees per second throughout the rev range.
Spray-guided direct injection delivers precisely measured quantities of fuel directly into the center of the combustion chambers at pressures of up to 150bar (2175 psi) , creating a more homogenous air-fuel mixture for cleaner and more efficient combustion. This is aided by spark plugs that are precisely indexed both in relation to the injector and within the combustion chamber.
The new Intelligent Stop/Start system offers fuel economy benefits under certain urban driving conditions. Stop/Start uses a twin solenoid starter, enabling the system to restart the engine quickly as the driver’s foot to move from the brake pedal to the accelerator. There is also a strategy for engine stop-start “change of mind” scenarios. This will bring the engine back up to speed even during its run-down phase if, for instance, the car is coming to a halt at an intersection when the driver sees an opportunity to join the traffic flow. As the engine is shutting down, but before it has completely stopped, it can rapidly restart by injecting fuel into the cylinders.
Standard for the V6 S and V8 S models and optional for the V6, an Active Exhaust system enhances the exhaust note. Electronically controlled bypass valves in the rear section of the exhaust open under hard acceleration, effectively providing a free-flowing straight-through arrangement. At cruising speeds, the valves will close, retaining a powerful exhaust note with comfortable sound levels.
Eight-speed ‘Quickshift’ Automatic Transmission
With eight closely spaced ratios in the Quickshift automatic transmission, the Jaguar F-Type driver can select a gear which will keep the engine within its optimal power band. The transmission was specifically tuned by Jaguar for the F-Type to prioritize acceleration. The V6 S model has a slightly lower (higher numerical) final drive ratio, 3.31:1 vs. 3.15:1 than the standard V6 model.
The entire drivetrain of the F-Type – up to and including tire contact patches – is tuned for optimal response to allow for ultra-fast transient torque delivery, which provides the driver with a high degree of responsive feedback. Importantly, once the transmission has shifted into second gear, a locking clutch bypasses the torque convertor, creating a direct mechanical link between the engine and the rear wheels. The Quickshift system enhances the sense of connectivity by ensuring sharp, immediate shifting performance via rapid and precisely timed engine torque intervention.
The operating parameters of the transmission are determined by the adaptive shift strategy that has 25 different programs available to it, depending on driving style and road conditions. The transmission can detect the manner in which the car is being driven by monitoring acceleration and braking, cornering forces, throttle and brake pedal activity, road load, kick-down request and even whether the car is being driven up or down hill. On detecting a more spirited driving style, the transmission will automatically make the shifts more aggressive and move the shift points higher.
In order to maintain the car’s balance during a downshift, the transmission will instruct the engine management system to automatically blip the throttle to match engine revs. This function also allows the transmission to perform multiple and very rapid downshifts during hard braking. Corner Recognition senses when the F-Type is negotiating a curve, the transmission holding its ratio to ensure the correct gear for the exit. The transmission will also recognize when the car is performing a series of overtaking maneuvers requiring rapid changes in throttle position. Rather than upshift, the transmission will hold a lower gear to remain ready for the next demand for acceleration.
Manual override of the transmission is available to the driver at any time, using either the steering wheel-mounted paddles or the console-mounted selector. Moving the shift selector to the left gate accesses manual mode, in which the driver pulls the lever rearward for an upshift and pushes forward for a downshift. If Dynamic Mode is also selected on the Jaguar Drive Controller, the transmission will not automatically shift up at the engine’s redline and will only downshift to prevent engine stalling, leaving control fully in the hands of the driver.
A Configurable Dynamics option is another first for a Jaguar. This allows the driver to select which elements of the Dynamic Mode are wanted so, for instance, the steering weight and throttle response can be sharpened while allowing the ride on models with Adaptive Dynamics to remain unchanged. Configurable Dynamics also adds functionality to the central touchscreen aimed at track use of the car. The system allows drivers to record lap and split times and will provide information on throttle and brake inputs and even G-forces generated.
Dynamic Launch Mode
The Jaguar F-Type S offers Dynamic Launch Mode for track-driving activities. When the car is stationary, the driver depresses the brake pedal while simultaneously building engine speed with the accelerator until a message reading ‘Dynamic Launch Ready’ appears in the instrument panel. That signals that the traction control has been set to help facilitate maximum acceleration. Releasing the brake while flooring the accelerator pedal keeps Dynamic Launch Mode engaged for maximum acceleration performance until the driver releases the pedal.
A mechanical limited-slip differential is fitted as standard to the F-Type S, which offers driver the opportunity to explore the car’s superb balance and outer limits of its grip within a progressive handling envelope.
The V8 S model is fitted with an active electronic controlled differential to maximize traction and offer even greater control. Inside the differential, an electric motor acts on a multi-plate clutch to transfer torque to the wheel with the most grip. Fully automatic in operation, the system can apply full locking torque almost instantaneously. Working in conjunction with the stability, traction and ABS systems, it allows for very fine control of power delivery and always makes the most use of available grip.
The three versions of the Jaguar F-Type offer progressively more powerful braking systems, all with the high levels of pedal feedback required for accurate modulation. The Jaguar Performance system fitted to the 340hp F-Type has 13.9-inch (354mm) front and 12.8-inch (325mm) rear brake discs with silver painted calipers. The F-Type S uses the Jaguar High Performance system, gaining larger 15-inch (380mm) brake discs at the front.
The Jaguar F-Type V8 S uses the Super High Performance system with the largest set of brake discs fitted as standard to a Jaguar production car, including the 15-inch (380mm) front and 14.8-inch (376mm) rear. All cars are fitted as standard with ABS, Electronic Brake Force Distribution and Emergency Brake Assist.
Jaguar engineers used Computational Fluid Dynamics to optimize brake-cooling using directed cooling air. Cold air is channeled to the brake discs via the air intakes flanking the grille and by the use of aerodynamically shaped suspension components to direct airflow beneath the car.
The aluminum structure of the F-Type ensures the best possible connection for the driver to the road. Every response from the steering to the transmission shifting, throttle, brakes and suspension has been finely honed to be as connected, accurate and involving as possible.
“Fundamentally, a great sports car is one you’ll look forward to driving because it’s fun, and the F-Type definitely delivers on that score. We’ve worked hard to make sure that responses to steering, throttle and brakes are absolutely immediate, a task made far easier by the rigid aluminum structure at the car’s base. It’s precise and exciting, a car that you’ll want to drive for the sake of driving alone – and it sounds fantastic.” Mike Cross, Chief Engineer, Vehicle Integrity, Jaguar
Agility in the Jaguar F-Type begins with its dimensions, which give the car a planted, “wheels pushed to the corners” stance. The F-Type measures 176 inches (4,470mm) in length on a 103.2-in. (2,622 mm) wheelbase. The track is wider in rear than front, 64.1-in. (1,585mm) and 62.4-in. (1,627mm), respectively.
Short front and rear overhangs also help in concentrating the mass within the wheelbase, reducing the moment of inertia and making the car much more immediate to turn in. To fully exploit this trait, Jaguar engineers paid particular attention to optimizing front-to-rear weight distribution. To that end, both the battery and windshield washer fluid reservoir have been placed in the trunk, rather than under the hood.
To give the steering the greatest accuracy in response and feedback, the F-Type uses an alloy front sub frame and very stiff front knuckles, also in aluminum. This arrangement allowed the fitment of the quickest steering rack ever used on a modern Jaguar, giving the driver a very connected-to-the-road feeling.
Every Jaguar is engineered and tuned to achieve an excellent balance between ride comfort and handling. In the Jaguar F-Type, that balance naturally tips in favor of involving, accessible handling while still maintaining excellent ride compliance. The Dynamic Mode enables the driver – at the push of a button – to emphasize the sporting character of the car by sharpening throttle response, increasing steering weighting, performing gear changes more quickly and higher up the rev range and by also raising the threshold for stability control intervention. Dynamic mode also prevents automatic upshifts when the gearbox is shifted into manual mode.
Additionally, the F-Type S and V8 S models are fitted with the Jaguar Adaptive Dynamics suspension damping system that controls vertical body movement, roll and pitch rates. The system continuously monitors driver inputs and the attitude of the F-Type on the road, adjusting damper rates accordingly up to 500 times a second to optimize stability and agility. The Dynamic Mode in these models also provides firmer damper rates through the Adaptive Dynamics system.
“Jaguar has a unique legacy of sports cars so the global expectations for the F-Type are immense. Developing it was therefore not just a great privilege but also a huge challenge. A Jaguar sports car is more than speed in its absolute sense; it is about its agility and its reactions to driver inputs, those millisecond responses to create a connection with the vehicle. This pure and predictable level of response is what enables the driver to exploit the potential and capabilities of the car as well as their own. Amongst the many test locations we use is our dedicated development center at the Nürburgring Nordschleife – a circuit unique in the demands it places on a vehicle. As well as being a very high-speed test facility, it is also very demanding of the transmission, the chassis and the brakes, allowing us to really exploit and test those final few tenths of the Jaguar F-Type’s abilities. Asking questions of every element of the F-Type’s performance attributes allowed us to hone them as a holistic, integrated package.” Ian Hoban, Vehicle Line Director
