The 2014 Porsche Panamera has been spied undisguised at the Nürburgring.

Looking virtually identical to its predecessor, the facelift model is distinguished by a new front bumper with larger air intakes and revised daytime running lights. The hatchback has also been equipped with new head- and taillights, a restyled rear fascia and a sportier exhaust system.

Engine options will likely carryover with minor modifications for improved performance and reduced fuel consumption. However, speculation has suggested there could be a new Audi-sourced V8 TDI as well as a twin-turbo 3.0-liter V6 that produces approximately 420 hp (313 kW).

The 2014 Porsche Panamera could be introduced at this year's Shanghai Auto Show which would be four years after it originally debuted there in 2009.
