This week has been a busy one as the automotive world continues to gear up for the 2015 Detroit Auto Show. BMW took the wraps off the 2015 M6, Luke Aker’s classic Maxima got restored, one man showed off his insane collection of DeLoreans, the Bloodhound SSC’s engine was tested, and the finalist for the 2015 North American Car and Truck/Utility of the Year were named. It’s The Week In Reverse, right here at Motor Authority.

The 2015 BMW M6 promises to be a slightly improved version of the existing M6, complete with minimally altered appearance and no changes to the powertrain. There are a nice list of improved and updated tech and M-specific bits, however.

Remember Luke Aker’s incredible cinematic Craigslist ad for his 1996 Maxima? That set the car and Aker off on a road that has ultimately seen it restored to its showroom glory—and there’s more in store to come from Motor Authority. Stay tuned to see just what it is.

If you’re a kid of the 1980s, or just a fan of the Back to the Future series, DeLoreans are pretty cool. But Rich Weissensel thinks they’re a whole lot more than cool—he’s obsessed. Check out his wacky collection of custom DeLoreans in a video released this week.

If you’ve ever wonder what the engine for a 1,000-mile-per-hour land speed record car looks like at full chat, strapped to a test bench, wonder no more. This is the rocket that will push the Bloodhound SSC toward its target—complete with a supercharged 5.0-liter V-8 that’s just used to pump the fuel.

This week also saw the revelation of the finalists for the North American Car and Truck/Utility of the Year. With just three contenders remaining for each of the two titles, there are many cars that didn’t make the cut—and only the very strongest new cars remain. Mustang, Genesis, or Golf? Colorado, F-150, or MKC? We’ll find out this January at the 2015 Detroit Auto Show.

You’ll find all of this and more at Motor Authority, so be sure to follow us on Facebook, Twitter, and Instagram to see it all as it happens.
