Jaguar reveals new Diesel Engine for the XF


A more efficient diesel cat

Jaguar has just unveiled its most efficient engine yet in the form of a new 2.2-liter diesel. Developing 190 PS and 332 lbs ft of torque, the new engine is capable of returning 52.3 mpg on the combined cycle while emitting 149 g/km of CO2.

The new four-cylinder 16-valve common rail diesel engine displaces 2,179 cc, and is still undergoing development with an XF test mule. According to Jaguar, the new engine features a water-cooled turbocharger with low-friction pistons, new injectors, a new crankshaft, oil pan and other electronic systems, including an intelligent start-stop system for improved fuel efficiency.

Along with a new engine, the development vehicle debuts a new eight-speed ZF automatic gearbox, as opposed to the older 6-speed ZF automatic. With the seventh and eight ratios effectively acting as overdrive gears, Jaguar claims the new gearbox allows the 2.2-liter engine to be optimized to deliver swift responses when required and improves motorway cruising ability to ensure the ideal balance between efficiency and performance. Jaguar claims acceleration figures for the 2.2 liter diesel at 8.5 seconds from a standstill to 100 km/h, and achieves a maximum speed of 225 km/h.

Locally, only 3 premium car brands offer diesel sedans: Audi, BMW and Jaguar.
