    I wasn't clear... It's going back into gear while still moving that is the question... some automatics/CVT's do not re-engage very smoothly/smartly when the car is already in motion. It's never a problem with a manual (where smoothness depends on the ability of the driver).

    Updated the first post with that point.

    That is the problem, you can put into neutral when coming to the traffic light but when you re-engage to D they don't usually likes it. I'm a lifetime manual user (20+ years) and I switch gear VERY smoothly if I may say so myself on manual so that is one thing I don't mind, switching gears as I'm used to it. CVT would be nice in asia since almost everyone is holding their phone while making calls instead of using bluetooth carkit.

    Doesn't the UK version of the Mirage have a taller 5th gear?

    BUT you point out the problem: we have to have a replacement gear set to swap in that fits. (Usually from some version of the same car model that comes with a different engine). We don't know about any such options for the Mirage yet.

    Yeah, but its really not that much taller. Its only going to drop your rpm by 100-200 at 60mph / 100kmh.

    maybe one day there will be enough owners that could find a manufacturer and make a group buy of a 5th gear assuming its a fairly easy retro fit

    just put the shift lever into N and its coasting... and if i am not mistaken the CVT already go's in somewhat of a coast when you let go of the gas pedal.. *( read no ICE braking )
    Automatic versions of cars usually still use the gas on N (neutral) rather than coasting on D (Drive) where there is no gas consumption.

    a automatic in D does not coast it will slow down on the ICE. ( depends on model ofcourse )

    And there is no on N coasting iether. As a current CVT driver I would personally recomend you to stay on D when you moving.

    Now having a look at this tread http://mirageforum.com/forum/showthr...-vs-RPM-chart)

    The USA spec manual has a 5th gear ratio of 0.804 and a final drive ratio of 4.055

    And the UK spec manual 5th gear ratio is 0.850 and a final drive ratio of 3.550

    So why not see if you can order in a new mirage manual fitted with the USA spec gearbox fitted with the UK spec final drive. Or order in a UK spec final drive gear ratio set and swap it in.

    I have not worked out the rpm drop at 100klm/h (62 mph) though should reduce rpms around 12.5%
