1.3 turbo diesel, 112hp, 155mph

This is a pure show car to demonstrate Opel's eco-technology. The Eco-Speedster, as indicated by its name, is an eco-friendly Speedster. On the one hand, it achieves a combined fuel consumption of 2.5 litres / 100km, or 113mpg. On the other thand, it can top 155mph.

Base on the Speedster (= Vauxhall VX220), Opel's engineers work on 3 area to achieve a low fuel consumption and high top speed:

1) Reduce drag coefficient from 0.38 to 0.20. As you can see, the Eco-Speedster is smoother than regular Speedster and has a F40-like rear window. It also has a flat bottom.
2) Reduce frontal area to 1.6m2. This is implemented by lowering the waistlines and narrowing the cockpit.
3) Employs a fuel efficient turbo diesel engine. This is Fiat's new Multi-jet 1.3-litre four-cylinder, with variable geometry turbo and higher boost to produce 112hp (compare with the production version's 70hp).

I wish we had the variable geometry turbo. In Thailand stradas, they eke out 14(?) additional HP from the 4D56 :D

boost control na lang! hehehe

pero hanep yung technology ng opel! imagine 112hp from a 1.3li TDI, and 113mpg pa! if this is the future of diesel technology, baka ma-relegate na lang ang gas sa sportscars.

splerdu,

kaya ba maka 10-15 hp increase with a boost control? Wala kasi dyno numbers with a 4D56 e.

Anyway, yes its indeed very impressive, specially with the displacement being so small. But recall the Honda F1 engines in the early 90's. Less than 3.0liters V6 Turbo lumalaban sa Ferrari V12...... and beating them! Si Ayrton Senna kasi e :D
