Peugeot's new executive-class sedan has spotted getting ready for a likely photoshoot in Madrid, wearing nothing but a car cover. Given the timing, we're guessing the new 508 sedan will get its world premiere at the Paris Motor Show in September and then go on sale late this year or in early 2011.

The 508 will likely share most of its underpinnings with the Citroen C5 and be powered by range of engines, starting with a gasoline 1.6-liter inline-four,and topping out with a 3.0-liter 240-horsepower diesel V6. The 508 is also expected to be available with Peugeot's new Hybrid4 through-the-road hybrid system.

This uses an internal combustion engine with a conventional transmission at the front wheels and an electric motor and battery for the rear axle. It's mechanically simpler than power-split systems like those from Toyota, and it offers on-demand all-wheel-drive.
