The 2016 Acura NSX is spied testing at the Nürburgring and burns to the ground the next day, we drive the 2015 Dodge Challenger SRT Hellcat and learn why that engine won’t end up in the Viper, and Tesla’s Model S succumbs to the rigors of the ‘Ring. It’s The Week In Reverse, right here at Motor Authority.

The 2016 Acura NSX has been on its way to production for so long we’d almost given up hope of its arrival. Then, this week, spy shots of the car testing at the Nürburgring  renewed that hope. That hope was almost immediately dashed again when shots of the car completely burned to the ground, still at the ‘Ring, surfaced a day later.

At the other end of the supercar spectrum is the Devel Sixteen. Claiming 5,000 horsepower and a top speed of 348 mph, thanks to a turbocharged V-16 engine, the car seemed like nothing but vaporware when it debuted last year. Then we spotted a video of the car running and driving in Dubai, and now it looks as if the car may be a real thing—though we still doubt the 5,000-hp V-16 aspect.

The 2015 Ford Mustang is nearly ready to reach the hands of press and enthusiasts around the world, but already, fans are looking forward to the higher-performance versions. One of those is expected to be the 2016 Mustang GT350, and a rendering released this week by Gurnade shows what it may well look like. Purposeful, if somewhat busy, but with an aggressive stance—we like what we see.

We drove the 2015 Dodge Challenger SRT Hellcat this week, and caught the experience on video as well as in text, and the sounds and sights are simply fantastic. To fully understand the Challenger Hellcat’s thunderous appeal, you have to be there in person—but we do our best to bring that experience to you through our eyes. If you’ve been hoping the Viper might get the Hellcat’s supercharged V-8, however, don’t bother—it’s not going to happen, and we know why.

Coming full circle, the week started with a trip around the Nürburgring in the Tesla Model S that ended abruptly—and early—when the Model S simply couldn’t hack the speeds and strains of the Green Hell, falling into limp mode just a third of the way into the 14-mile circuit. Of course, we don’t love the Model S any less for that fact—it’s not a track car, and it’s not intended to be. We just wish we’d seen its true potential come through.
