As Sebastian Vettel and Mark Webber have proven all season, the Red Bull RB6 is the quickest car in Formula 1, but thanks to the major regulation changes for 2010, it had to be far more than an evolution of last year's impressive RB5. How does it work? How did designer Adrian Newey steal such an advantage on Ferrari, McLaren and Mercedes? And now that the car's reliability has improved, will the Formula 1 World Championship ultimately dilute into an internal war between super-fast Vettel, and almost-as-fast and experienced Webber? Renowned F1 journalist Mark Hughes has dug deep for the answers, and explains all in the June issue of RACER magazine.

Also on tap in the June issue:

Danica Patrick will try to revive her 2010 IndyCar Series fortunes at the event in which she traditionally shines – the Indianapolis 500. But Jeff Olson wonders whether that will be enough to keep her in open-wheel racing or if she will make the full-time switch to NASCAR.

The 2010 Indy 500 has a variety of intriguing story lines and, at the risk of being proved wrong by events on May 30, RACER editor David Malsher has attempted to be your guide. He also got on the case with Rick Mears, Jimmy Vasser, Johnny Rutherford, Justin Wilson and Will Power to discuss the arts of teaching and learning oval racing, while Power's race engineer Dave Faustino reveals the smarts that both he and his driver have picked up on ovals and at Team Penske. (For Mears, Vasser and Rutherford explaining the techniques needed at Indianapolis Motor Speedway, click here).

Other Penske employees who have been shining this season are Kurt Busch and his crew chief Steve Addington. While Addington was discarded by Kyle Busch late last year, his older brother has discovered that the quiet South Carolinian is exactly what's needed to make Penske Racing's famous No. 2 a consistently competitive car.

How did the remarkable John Force become a title-contender again? Despite everything you know about the 61-year-old legend, his candor in explaining his revival will still shock you. His resolve and determination won't.
