Hot on the heels of reports of a refresh for the Porsche 911, our spy shooters spotted what is believed to be a GTS version of the updated sports car lapping the Nürburgring in Germany. The introduction of the Porsche 911 GTS will likely coincide with a light facelift for the 991-generation 911.
These spy photos purportedly show this refreshed Porsche 911, likely called the 991.2 generation, which is expected to debut next year. Compared to the current car, this tester's front fascia, headlights, and taillights are lightly restyled. Unlike a previous refreshed Porsche 911 tester we spotted in the winter, however, the car seen here at the 'Ring has a pair of centrally mounted exhausts.
If it follows the pattern of past Porsche 911 GTS models, expect the new car to have a tad more horsepower than the 400-hp 3.8-liter flat-six in today's 911 Carrera S -- possibly as much as 425 hp, according to earlier reports. The last 911 GTS had 23 hp more than the contemporary Carrera S version.
When the Porsche 911 is updated, our colleagues at Motor Trend suggest it could also benefit from new plug-in hybrid engines. It's possible the Turbo S model will use technology inspired by the wild 918 Spyder hypercar, with an electric motor helping boost the engine's power to as much as 730 hp -- compared to "just" 560 hp in today's 911 Turbo S. A 156-hp electric motor would reportedly be sandwiched between the flat-six engine and the PDK dual-clutch transmission.
Look for Porsche to introduce the refreshed 911, as well as its GTS derivative, at a major auto show late this year or early in 2015.
