VW DSG box is a good example, but you find them on most supercars, they sound like F1 cars when the change up/down  |

Ok, as I understand it (and my understanding is not great) what this means is that the car has two clutches, one to operate the odd gears and one the even. Gear changes are, therefore, faster because gear changes are made without interrupting torque distribution. In other words, the torque is applied to one clutch at the same time as it is being disconnected from the other clutch. So, I think the answer to your question is that they are more efficient whether in automatic or manual mode. I am now waiting to be told I'm talking nonsense.....  |

Sounds good hopefully drivingspirit are right about there being a dual clutch on the way for the AGP then! |

It'll be for the APE not the AGP  If they make for one, they should make for the other. Anyway the AGP and the APE are basically the same car mechanically so even if they did make it for the APE surely it could still be fitted to the AGP |

True but would you not be able to get hold of 1 and have it fitted on the AGP |

It would cost thousands. |

Looks like no chance of a dual clutch then  |

Just been rattling this through my head, bearing in mind a) I have the engineering nouse of a dead squirrel b) for a direct like for like gearbox/clutch change on my old 159 we worked out cost the better part of 4k given parts and labour, this is roughly what I reckon you'd have to go through: Rip out the old clutch and gear box, gear change and mechanical linkages. Put in new DC box, realise it won't fit as its a different size, shape and mounting. Once that's been overcome its likely all the transmission system will need to be replaced to also get it to fit with the new box unlikely the current prop shaft would be exactly the right size. Mount new auto style gear shift and wire it to the box. All the time trying not to mangle your interior/bodywork The entire thing is also dependant on the engine management system so new ecu to cope and wiring loom and rewiring of the car to get all the sensors talking. That may or may not marry the box to the active safety systems, if not that will need to be done as well which would also likely involve rewiring a portion of the car. I dare say there are a million nuances I couldn't possibly think of though TL:DR No |

I bet it would be cheaper to sell you car, then buy a new one with the dual clutch |

What I can't understand though is how the EVO is already in production but this dual clutch thing is gonna be for them, surely this would come down to all the same problems as fitting one to the AGP |
