A prototype of the next Porsche 911 Carrera GTS might just have been caught on camera, setting the pace at the infamous Nürburgring Nordschleife during an Industry Pool event at the race track. YouTube's Automotive Mike uploaded a video of the forthcoming sports coupe as it went through testing, its tires howling in pain as they fought to keep the Type-992 Porsche on the pavement.

Historically, the Carrera GTS has occupied a unique space within the greater Porsche 911 lineup, splitting the difference between the ordinary Carrera and Carrera S, and the more "hardcore" models like the GT3.

What leads us to believe that this is, in fact, the Porsche 911 Carrera GTS? The model is given away by just a handful of small styling tweaks, the most notable being a reshaped front fascia with a more pouty grille and angled side inlets, and a higher-mounted license plate on the rear of the car, above a redesigned bumper cover. The brakes also appear to be larger than on the next-step-down Carrera S.

Strangely, though, the coupe in this video appears to be missing the telltale center-lug wheels, instead borrowing a set of five-lugs from elsewhere in the lineup. We expect the production version of the car to use center-lugs, however, as a few previous spy sightings indicate they'll be used.

The all-new Porsche 911 Carrera GTS is expected to bow sometime before the summer of 2020 as both a coupe and a cabriolet, going on sale as a 2021 model by the end of the year. Power will most likely come from the same twin-turbocharged 3.0L flat-six as the Carrera S has, tuned to send as much as 475 horsepower or so through a 7-speed manual or 8-speed dual-clutch automatic transmission.

Granted, that's just our best guess. To get the official specs, we'll just have to wait until the GTS bows for real sometime later this year.
