Toyota is rolling into this year's L.A. Auto Show with a redesigned Mirai – the company's hydrogen-powered electric car – and it looks far better than its predecessor. Part of that is due to the Mirai's new, rear-wheel-drive platform. The current model powers the front wheels. Powertrain details remain under wraps, but the automaker is targeting a 30 percent increase in range over the current model, so expect around 400 miles when it goes on sale late next year.
