Development work continues on the 2015 Porsche Cayenne as our spies have caught the model undergoing testing on the Nürburgring.

Snapped wearing minimal camouflage, the facelifted crossover has a new front fascia with a revised grille and restyled headlights. The subtle styling tweaks continue out back as the model has new taillights and a revised rear bumper with an integrated diffuser.

Despite looking pretty evolutionary, big changes are expected under the hood. Nothing is official but the Cayenne S will likely adopt a twin-turbo 3.0-liter V6 that develops 413 bhp (308 kW) and 385 lb-ft (520 Nm) of torque.

There could also be a new E-Hybrid variant with a 316 bhp (235 kW) 3.0-liter V6 engine, a 94 bhp (70 kW) electric motor and a 9.4 kWh lithium-ion battery. This could enable the model to have a combined maximum output of 410 bhp (306 kW) and an electric-only range of up to 22 miles (35.4 km).

The facelifted Cayenne is expected to be introduced sometime next year as a 2015 model.
