i think you numptys are all missing the point a little.
Yes the next
ibiza will have a 6 speed box, like all cars now the increase in the need to drop the emmsions outputs means they will have to. You only have to look at the latest Corsa CDti which has had a change of cogs to lower the emssions under 120g/km.
Gearbox specialists have contracts in at the moment to develope gearboxes to
help lower emsissions. in fact ZF have nearly finished an 8 speed Auto which lowers emisions by 20%. With silly targets set by the EU to lower the average emissions output to 130g/km by 2010 the mechanicals of the car and weight are now seen as the vital part to get emissions down.
Thus you will also see less 4Wd cars and permanent 4wd will be a thing of the past soon.
aside from the real reason. there is one other too.
All of us will remember the Focus St 170 that was released before the Focus RS. Well this came with the Getrag 6 speed gearbox a great gearbox too ( its the same as the Mini cooper S's). Anyway when they were designing the Focus RS they assumed first off that they would go for the 6 speed in it. but during testing it just did not feel right, they could not get the ratios right, thats wehy the Focus RS ended up reverting back to a 5-speed gearbox as it matched the engines characteristics much better.
Hopwever there are cars that do need a 6 speed, and after owning one i would not say the
ibiza 1.8t is one of them. However other cars like the peugeot 206 Gti 180 were in desperate need of one. my mates pug would cruise at 5000 rpm at like 90 ish. Way too high.
