Chevrolet is unveiling its highly anticipated C7 Corvette at the 2013 Detroit Auto Show, but the new eight-speed automatic transmission that General Motors will introduce in this car reportedly won't be ready for at least another year. No, this doesn't mean that the C7 will only come with a manual transmission at launch. According to Motor Trend, what it does mean, though, is that the Corvette will rely on an eight-speed auto sourced from Aisin until GM's in-house transmission is ready.
Last year, Lexus became the first automaker to introduce a production eight-speed automatic transmission in the latest LS460. Recently, German transmission manufacturer ZF announced a new eight-speed of its own which is claimed to provide a 14-percent boost in fuel efficiency compared to a five-speed. It looks like Audi and BMW will likely be the first to directly challenge Lexus when they start using the ZF. Audi may be first out of the gate in 2009, with eight-speed installations in the A8, Q7
