The GTS will likely boast more than 500 horsepower, which should enable it to beat the 4.0 second 0-60 mph time of the Panamera Turbo.

Porsche's Panamera lineup is poised to expand as the company is reportedly working on a new diesel variant as well as a high performance GTS.

Although little is known about the Panamera GTS, it is expected to be positioned above the Panamera Turbo. This means the GTS will likely boast more than 500 horsepower, which should enable it to beat the 4.0 second 0-60 mph time of the Panamera Turbo. The GTS is also expected to ditch the Turbo's heavy air suspension system, in favor of traditional coil springs.

According to Autocar, Porsche is also considering a diesel-powered Panamera. If such a model were to be built, it would likely adopt a modified version of the Cayenne's 240 bhp 3.0-liter V6 or the Audi A8's 322 bhp 4.2-liter V8.
