for Fuel Efficiency

Typically, over 70% of a vehicle’s lifetime carbon footprint will come from the fuel it uses, when driven. Designing fuel efficient vehicles is therefore key to reducing our impact on the environment, as well as delivering cost savings for customers.

We are aiming to reduce our fleet tailpipe emissions by 25% by 2015.This calls for fresh thinking at the product design stage. Analysing engine performance, aerodynamics and more to inspire new ways to drive down emissions.

Our approach focuses on four key areas:

1.     Lightweight Body Structures

Jaguar pioneered the use of lightweight, aluminium body structures. More lightweight and malleable materials not only offer improved aerodynamics, they also reduce the size of the engines required to deliver power.

2.     Hybrid & Electric Solutions

We have a team of 260 engineers exploring how internal combustion engines can work with electric motors as well as ways in which vehicles can recover the energy they lose in braking and driving. This work has led to the launch of our Range Rover Sport Hybrid - the world’s first hybrid luxury SUV. With CO2 emissions as low as 169g/km  and 44 miles per gallon, emissions from the Range Rover Sport Hybrid are 26% lower than the standard diesel model.

3.     Stop/Start Technology

This kind of intelligent technology offers significant fuel saving opportunities. In the All New Range Rover, the system shuts down the engine in just 300 milliseconds when the vehicle comes to rest, then restarts as the driver’s foot leaves the brake pedal – reducing fuel consumption and CO2 by between 5% to 7%. 

4.     Powertrain Efficiency

Advances in powertrain efficiency are helping us create engines that deliver high performance with fewer emissions.
