The coupe and cabriolet get a workout in these new photos.

Rather than introducing the new 3.0-liter biturbo flat six in every model at once, Porsche is slowly incorporating the engine into the 911 lineup. With the standard variants done, these spy photos are further proof that work on the slightly hotter GTS is now underway at the Nürburgring.

Compared to other versions of the 991.2, Porsche gives the GTS a new front bumper that has additional center intakes. It also rides on center-lock wheels, which are very similar to the units on the Turbo S. As with the current GTS, this one continues to wear the wide-hipped body from the Carrera 4, but customers likely still have the option of rear- or all-wheel drive. This batch of shots shows the coupe and cabriolet testing, and earlier photos reveal the Targa’s development, too.

While the switch to the biturbo 3.0-liter is a certainty, we don’t know the engine's specs in the GTS yet. Expect a bump over the 420 horsepower and 368 pound-feet in the current Carrera S, though. Buyers can likely pick from a seven-speed manual or PDK dual-clutch gearbox to get to power to the wheels. The company would also probably include some standard performance features like the Sport Chrono package and Porsche Active Suspension Management.
