BMW 135is coupe and 135is convertible available for order

BMW announced that it will expand its 1-series lineup with the addition of the 2013 BMW 135is coupe and 135is convertible.

That's a 20-hp and 17-lb-ft increase over the 2012 135i, but BMW claims that the vehicles will maintain both the fuel-economy and emissions ratings of the 135i.

The thing that really sets him apart is that, while competitors shared driving duties over the long desert courses, Stewart did the vast majority of them alone, with no relief drivers--just him and the dirty, dusty desert. But even legends want to retire someday.
