According to a company spokesperson:
Why wait two years when other countries already have subsidies? There is now a danger that the proposals will actually stall the market for electric vehicles over the next two years. If the government really wants people to go green, then why not do it now?We don't necessarily have anything against the two-seat G-Wiz, which recently got an upgrade to lithium ion batteries that push its range up to 75 miles and its top speed to 51 mph, but it's definitely not a vehicle with as much mass-market appeal as something like the Ampera, which can seat 4 occupants and surpass any speed limit in all of Europe. We'd hazard a guess that this is why the government's program is timed to coincide with the launch of mainstream electric vehicles.
