The Porsche 911 Turbo is inching closer to production as our spies have caught the model virtually undisguised.

Snapped undergoing testing in Europe, the car features unique bumpers, a prominent spoiler and widened rear fenders. We can also see high-performance brakes and a four-tailpipe exhaust system.

Power could be provided by a tri-turbo 3.8-liter six-cylinder engine with approximately 525 hp (391 kW / 532 PS). Details are elusive, but the tri-trubo system will reportedly improve efficiency and increase boost response at low speeds.

The 2013 Porsche 911 Turbo could be introduced this summer, so stay tuned for full details.
