The engine is perfectly complemented by the all-new 8-speed ZF automatic gearbox. Specifically adapted by our engineers for its first-time application in a Jaguar, the transmission offers a host of benefits including both improved acceleration and economy. Gearchanges are completed in just 200 milliseconds - four times faster than the average human resting heartbeat - while driver control is enhanced by the ability to perform multiple downshifts using the paddleshift technology. The use of lightweight materials ensures the overall weight remains the same as the previous six-speed transmission, while improved pump design and gear control elements increase efficiency. Standard on all Jaguar XF diesel models, it reduces the CO2 emissions of the 3.0-litre V6 to 169g/km and improves fuel consumption to 44.8mpg.
