Jaguar has announced a range of enhancements to its F-Pace performance SUV and XF and XE sports saloons. The 2018 model year updates will see the debut of Jaguar Land Rover’s latest Ingenium engines, with a pair of all-new four-cylinder Ingenium petrol engines introduced alongside a high-output 240PS diesel powerplant.
The new 200PS (available with XE and XF) and 250PS 2.0-liter four-cylinder Ingenium petrol engines use Jaguar Land Rover’s low friction all-aluminium-intensive design to provide excellent thermal properties and lightweight construction for improved efficiency and enhanced vehicle dynamics. Models with the 200PS engine wear a 20t badge while 250PS derivatives are identified by 25t badging.
Jaguar’s diesel range is also bolstered by the introduction of the 240PS 2.0-liter four-cylinder twin turbo Ingenium diesel. This high output 500Nm engine delivers traditional Jaguar performance without compromising running costs.
Jaguar’s revisions to the Ingenium engines have been undertaken to ‘optimise efficiency and refinement’ while the new petrol units deploy twin scroll turbos to reduce lag, optimising power output and efficiency.
The new 200PS and 250PS powerplants feature electrohydraulic valve control for increased flexibility across its operating range. This patented technology provides fully variable control of the intake valve lift for optimum efficiency, power and torque across the rev range. In addition, cleaner combustion is ensured by a new 200-bar direct injection system, which features centrally mounted injectors with optimised spray patterns to improve efficiency and reduce emissions.
In a first for Jaguar, the exhaust manifold is also integrated with the cylinder head casting. Passing coolant through the manifold considerably reduces warm-up times, when engines are at their least efficient, to enhance fuel consumption and reduce emissions.
The strengthened engine has uprated pistons, crankshaft and fuel injectors and is the first four-cylinder Jaguar Land Rover engine to deploy the use of twin-turbos. The sequential configuration of the units boosts power at high engine speeds, while improving responsiveness at low rpm. Models fitted with the new diesel engine wear the 25d badge.
“We are committed to expanding the Ingenium powertrain family produced at our award-winning GB£1bn Engine Manufacturing Centre in Wolverhampton as we meet current and future consumer needs,” added Nick Rogers, executive director – Product Engineering.
