TfL have signed a deal with General Motors UK (Vauxhall) for a 3 year deal, with option for a further 2 years, to provide complete testing facilities for buses "and other commercials" at its Millbrook test site in Bedfordshire. The contract covers bus emissions, noise, performance, track testing, new specifications of vehicles, (such as hybrid or electric buses)new Euro 6 approved vehicles.
No prizes for guessing what is going to be tested here then. The photo accomponying the blurb is of the New Bus For London.
