Detroit mogul, race team owner, and billionaire Roger Penske has a squeaky clean, no nonsense, business first image.

Yesterday evening, NASCAR revealed that Penske Racing driver A.J. Allmendinger is now indefinitely suspended from competition after he tested positive for a banned substance.

As we told you on Monday, NASCAR Sprint Cup Driver AJ Allmendinger was temporarily suspended from competition after he failed a mandatory drug test before Saturday's Coke Zero 400 in Daytona.

Now that Saturn is officially, truly dead, we thought we'd reflect on the history of a GM division that tried, with varying degrees of earnestness, to be a different kind of car company. Luckily, we've done that once already.

GM has just announced plans to "wind down the Saturn brand" — effectively killing it after Penske Automotive announced plans to terminate its discussions with GM to buy the Saturn brand.

We're told the hottest up-and-coming Sprint Cup free agent is Brad Kesolowski. Nobody knows where he'll end up, but speculation's focused on Roger Penske's #12 car. Today, an anonymous tipster spotted Kesolowski meeting with Penske. Full report below.

GM will officially be selling the Saturn brand to Roger Penske for an unknown sum. GM will continue building Saturns on contract with Penske for them to distribute through Saturn's current dealer network. Full press release below.

GM's apparently agreed to sell Saturn to Jalopnik's favorite Detroit-loving, mega-dealer-owning, truck-renting and smart-car-selling Roger Penske, with a deal expected to be announced today. So we guess this means there's now a fourth "U.S." automaker in Detroit. [NYT Dealbook]
