The petrol engine replaces the 16v 2.0 litre engine in the SRi and Executive models and boosts performance, giving a 0-62 mph time of 10.3 seconds and a top speed of around 130 mph. The 2.1 litre turbodiesel - with 12 valves covering its four cylinders - will sell alongside the 1.9 litre turbo diesel on all except the L models, lifting the number of models available from 18 to 23.
