Considering how competetive the TC3 is, how radical would AE want to go with the TC4 redesign?
I can't remember how long the TC3 has been out, but it seems like at least 4-5 years since it's initial release. That isn't a bad run for a car, and it is still as good or better than anything else out there.
To also consider the current economy, it would be foolish for AE to invest a lot of money in a redesign of this kit.
I would not be surprised if the TC4 is only a minor redesign to incorporate some of the modifications most of us have already made to the car. This could include moving the batteries in closer to the centerline and maybe some version of the NTC3 steering. If this is the case, it would be reasonable that a new kit could be on the way some time next year.
Who knows..... I guess we'll just have to wait and see.....
