Four engines will be available from launch all featuring Jaguar's proven six-speed automatic transmission with steering wheel-mounted 'paddles' for manual gear selection (Jaguar Sequential ShiftTM):
2.7-litre V6 twin-turbocharged diesel
The Euro IV compliant twin-turbocharged 2.7-litre 24-valve V6 diesel delivers high efficiency, high performance and class-leading refinement and is the lightest diesel engine of its type and size - making a significant contribution to the new XF’s power-to-weight ratio, performance and fuel economy.
3.0-litre V6 petrol
The 3.0-litre V6 petrol engine is another compact, lightweight, all-aluminium design with four overhead camshafts, four valves per cylinder, VCP Continuously Variable Cam Phasing and variable geometry air intakes.
4.2-litre V8 petrol and 4.2 s/c V8 petrol
The 4.2-litre V8 comes in naturally aspirated or supercharged versions. With a ribbed aluminium block and cylinder heads it is very light but extremely strong, and its superb structural stiffness minimises radiated engine noise and increases mechanical reliability. The V8’s exhaust system has also been completely retuned to remain quiet at cruising speeds but deliver a substantially more purposeful V8 roar under hard acceleration.
Transmission
A superior six-speed automatic transmission – renowned as one of the best in the world and already proven in other Jaguars - is used on all versions of the new XF. There is no manual gearbox option. Key to the XF's sporting character, the six-speed automatic transmission incorporates adaptive gear-changing strategies responding both to road conditions and the way the car is being driven.
The transmission is controlled by the new JaguarDrive SelectorTM with the option of manual selection through Jaguar Sequential ShiftTM. The JaguarDrive SelectorTM is also used to access the XF’s Sport mode which uses shift-by-wire technology pioneered on the XK.
Every XF model has shift-by-wire transmission control, with Jaguar’s class-leading sequential shift system, popular with XK sports car customers and used for the first time in a saloon. The Jaguar Sequential ShiftTM System gives the driver the option of one-touch manual gearchange control via steering-wheel mounted paddles. There are also multiple JaguarDrive ControlTM transmission modes, including Dynamic and Winter settings, which interact with throttle progression, Dynamic Stability Control thresholds and shift strategy to match mood and conditions.
Suspension
The V6 petrol, V6 diesel and V8 naturally aspirated models all use finely tuned passive suspension whilst the SV8 uses Jaguar’s Computer Adaptive Technology Suspension (CATSTM). The latest CATSTM is a sophisticated system shared with the new Jaguar XK sports grand tourer. It uses electronically controlled, two-stage, adaptive dampers whose characteristics are automatically adjusted within milliseconds in response to road conditions and driving inputs, for the optimum balance between comfort and control.
