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.
