Polo 1.4 FSI: Direct-Injection Petrol Engine For Tough New Supermini

The Polo 1.4 FSI is the herald of a new generation of highly economical and low-emission petrol-engined vehicles for Volkswagen. It is capable of consuming an average of only 47.9 mpg on the EU combined cycle – up to 30 per cent more economical than some conventional petrol rivals. With direct injection and a pioneering exhaust treatment system, FSI marks a new era in spark-ignition engines.

The engine is based on the proven 75 bhp 1,390 cc unit – also offered in the Polo – and produces 86 bhp at 5,000 rpm with maximum torque of 96 lbs ft (130 Nm) at 3,500 rpm. The direct petrol injection system favoured by Volkswagen, in conjunction with a special method of exhaust treatment, ensures considerable advances from an environmental point of view.

On the FSI engine, an exhaust treatment system electronically monitored by the engine’s electronic control unit ensures that pollutants are converted into non-toxic gases. Exhaust gas is cleaned by a three-way catalytic converter, which at the same time assumes the function of a NOx accumulator catalyst, and a NOx sensor. The direct injection of the fuel is achieved through a common-rail system. At a pressure of up to 100 bar the petrol is injected directly into the combustion chamber via individual electromagnetic injectors.

Not only is this new Polo economical, it is also a lively performer with a top speed of 111 mph and a 0-62 mph figure of 12.1 seconds. Standard equipment includes ABS; driver’s, front passenger’s and front side airbags; central locking; alloy wheels; alarm; and electric windows.

The Polo 1.4 FSI is on sale now with three or five doors, in SE and Sport trim. ‘On the road’ prices range from £11,580 to £12,800. Until the end of this year, free insurance is offered with every new Polo E, S and SE, adding further value to the Polo package.
