Jeep has launched an updated version of the Grand Cherokee, bringing CO2 emissions below 200g/km for the first time.

Customers will be able to choose a 198g/km variant using the latest version of the 3.0-litre V6 diesel.

The 2014 Jeep Grand Cherokee is available in Laredo, Limited, Limited Plus, Overland and the exclusive top of the range Summit equipment grades.

All these models feature the 3.0-litre CRD engine which employs Fiat Group Automobiles’ MultiJet 2 technology.

The Laredo model features a lower-powered version of the CRD engine while the high-performance SRT gets the petrol 6.4-litre V8 HEMI engine delivering 461 bhp.

The vast majority of 2014 Grand Cherokee sales will be powered by the 3.0-litre V6 turbo diesel. This engine produces its maximum power of 247bhp at 4000rpm while torque is a hefty 420lb-ft at 2000rpm.

The powertrain is also offered in a low output version which delivers 188bhp at 4000rpm while torque stands at 325lb-ft between 1600 and 2800rpm. The 37.7mpg fuel consumption has been improved by 10% compared to the previous model while CO2 emissions stand at 198g/km, a 9% reduction.

Both petrol and diesel engines use an eight-speed automatic transmission, while the car also has an Eco mode to help reduce fuel consumption. Prices start at £36,995 on the road.
