FORD has unveiled an all-new prototype 1.1-litre three-cylinder direct-injection petrol engine which the manufacturer says will meet all Government thresholds for carbon dioxide emissions. The engine has been developed as the Government prepares a reform of company car tax which in April 2002 will become based on CO2 emissions.

Launched at the Frankfurt International Motor Show, it is believed the engine will meet both the Government's lowest CO2 threshold and smallest engine banding. Ford is refusing to say when the Zetec-SE I3 DISI 74bhp 1.1-litre engine will make its way into the UK and in what model.

Jim Clarke, Ford's chief engineer, advanced vehicle technology, said: 'This prototype direct injection petrol engine is just one example of the many exciting powertrain developments coming from Ford. It delivers the real-world performance the customer wants but with improved CO2 emissions, especially where they are needed most in heavy traffic and city driving conditions.'
