Here’s the first public look at the NASCAR roll cage for 2013, built to comply with rules changes for next year intended to improve driver safety.

Mac’s Motor City Garage is indebted to ace fabricator Kevin Bryde of Earnhardt Ganassi Racing, who provided these photos and supplied the technical briefing.

First, in the photos above and below, note that the halo bar—the tube around the top of the cage that roughly describes the roof perimeter—has been doubled up with a second tube (yellow arrows) at the front along the top of the windshield. Now there are two full tubes, generously spaced, across the leading edge of the cage in front of the driver’s forehead.
