SEAT has slashed the CO2 output of the standard Ibiza1.4 TDI with the modifcations that come as standard with the ECOmotive. And it's done it by making simple, cost-effective changes. This is a really intelligently thought-out supermini which shows you don't need expensive hybrid technology to get great efficiency.

ECO really is the name of the game for this SEAT! The Spanishfirm claims the new Ibiza ECOmotive will be the most economicalfive-door on sale in Britain when it arrives in March.

The sporty-looking supermini gives combined fuel economy of 76.3mpgfrom its 1.4-litre turbodiesel - without an expensive hybrid engine. Instead,the motor features tweaked electronics, energy saving tyres and honedaerodynamics. It's also been on a diet to cut its weight to 1,579kg.

What's more, the Ibiza is 'economical' in more ways than one! SEATplans to sell it for £11,000, which is £7,000 less than a Toyota Prius.It's cheaper than the forthcoming 98g/km Ford Fiesta ECOnetic, too.

You have to do without air-conditioning, which is a £500 option -although fitting it doesn't affect the CO2 rating, which comes in atonly 98g/km. This means the ECOmotive is exempt from road tax, whilethere are further tax benefits for companies which run the car on theirfleets.

The newcomer looks sportier than standard models too. There's loweredsuspension, plus racy headlights and door mirrors from the Sportvariant. Inside, the cabin feels well built,and isn't short on space.

So,how does it perform on the road? Well, there's certainly no mistaking the vocal,clattery three-cylinder motor.

To be fair, it's smoother and quieter at speed, but still isn't as refined as a modern common-rail unit. And it's punchy. A total of 195Nm of torque means the engine responds smartly to the accelerator. This is particularly apparent in the Sport Coupé three-door variant, which is the same price as the five-door.

The light, crisp steering of standard Ibizas remains. And while thehigh tyre pressures have made the ride feel less comfortable thanbefore, it's fun through the corners.

The rubber offers good turn in, and while grip isn't huge, well judgedsuspension settings mean it's nimble to drive. This Ibiza looksfantastic value, then, and going green has never been more fun!
