NASCAR: Rule changes to be clarified

The 29th annual NASCAR Sprint Cup Series Media Tour opens on Monday in the Charlotte, N.C., area. It's a four-day smorgasbord of announcements, team-shop tours, optimistic predictions and the unveiling of new race-car paint schemes, team members and sponsorships. More than 150 writers, broadcasters and photographers will get a steady diet of claims such as “we're excited,” “we've been working harder than ever,” “we feel we've got everything in place” and “we can't wait to get started.” The tour will visit almost every team that plans to run the full series schedule in 2011, teams such as Earnhardt-Ganassi, Stewart-Haas, Penske, Michael Waltrip, Richard Childress, Kevin Buckler's TRG, Team Red Bull, Furniture Row, Richard Petty, Hendrick, Roush-Fenway and Joe Gibbs.

Some will even take a test drive while having no intention to buy a car.

The new BMW i3 EV (pictured) will be subsidised until 2017. The subsidy of up to £5000 paid to buyers of electric cars has been with us for three years, but it hasn’t had much impact on EV sales and it did look like the government had decided to scrap it all together. But it looks like the coalition has allowed Nick Clegg to have his way with EV subsides in a move that will see £500 million injected in to promoting and supporting electric cars in the UK in the next few years.
