Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show. It's an A7 Sportback given the hardcore RS treatment, meaning a 552bhp and 516lb ft 4.0-litre bi-turbo V8 that will sprint the RS7 to 62mph in 3.9sec. That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.

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.

Daimler and BYD name new brand Denza

Mercedes-Benz sources in Germany have confirmed Chinese media reports suggesting that parent company Daimler and Chinese carmaker BYD's new joint venture brand will be called Denza. Created as a Chinese-market-only brand, Denza is planned to support a range of "affordable" electric-powered vehicles, the first of which is set to be unveiled at the Beijing motor show next month. Based on the underpinnings of the first-generation Mercedes-Benz B-class--a car originally designed to accept batteries within its flat floor structure--the first Denza model was developed in China by a team of engineers from both Daimler and BYD Auto.
