BMW revealed the new 2016 7-Series flagship; Ford showed off the 2016 Mustang Shelby GT350R's exhaust modes; and official specs for the new Batmobile for the upcoming 'Batman v Superman: Dawn of Justice' movie were revealed. It's the Week In Reverse, right here at Motor Authority.

After many leaks, BMW finally revealed the new sixth-generation, 2016 7-Series flagship sedan. Arriving in showrooms this fall as a 2016 model, the new 7-Series is packed full of technology like a gesture control interface and carbon construction, and it will be available as a plug-in hybrid. The car makes its auto show debut this September at the 2015 Frankfurt Auto Show.

America's own AMS Performance has been working on a twin-turbo kit for the first-generation R8 V10, and until this week, it was keeping it under wraps. Now, with development and testing done, the tuning company has strapped its creation to the dyno and says it's already delivering more than 1,300 horsepower to the wheels. A byproduct of all this? It's basically a flamethrower now.

We caught the upcoming 2016 BMW M2 undergoing what must be final shakedowns on the Nürburgring in Germany. Set to be shown in September at the 2015 Frankfurt Auto Show, the new M2 will feature a turbocharged 3.0-liter straight-six with about 375 horsepower. Can't step on the M3 and M4's toes, right?

Ford brought the new 2016 Mustang Shelby GT350R to the Carlisle Ford Nationals and showed off the exhaust system. Turns out there are actually four different modes on the GT350R. We hear a host say something about a normal mode to not piss off your neighbors at 6 a.m., but beyond that, it all gets garbled with the exhaust screaming.

The rumors can stop now regarding the Batmobile for the upcoming Batman v Superman Dawn of Justice movie, because we now know official specs courtesy of the 2015 Licensing Expo happening in Las Vegas. It's 20 feet long, 7,000 pounds, and supposedly able to reach 205 mph. It's basically insane.
