General Motors has declared that Opel/Vauxhall is in need of a minicar, something to compete with the Ford Ka and Peugeot 107.
Opel released a minicar concept called the Trixx five years ago, but it never made it to production. Many, many manfucaturers are in the minicar market, with more to come, so a move like this was expected eventually.
General Motors also mentioned that they were considering a battery powered electric car. There were reports a couple of months ago that they were considering teaming with Reva (Makers of the awful G-Wiz) to make an electric Chevy Spark, so that might be what they’re talking about.
