Two concepts from Volkswagen-owned design house Italdesign Giugiaro, leaked via European patents, show off a future design for a Golf/Scirocco-sized vehicle and a Polo-sized vehicle.

The Golf-sized Volkswagen concept shows off a new, more angular nose with lights integrated into a sharper grille. It's both crisper than the jellybean-styling of the current Golf and more defined than the I'm-in-the-witness-protection-program vague look of the new Jetta.

It's not entirely clear if the Polo-sized vehicle's a preview of the next generation version of the tiny VW, or if it's a more refined version of the VW Up! concept. Either way, it gets the same fascia treatment and a similar greenhouse with a belt-line that dives into the door.

Both of these concepts are likely to show up Geneva and, given Giugiaro's long history with Volkswagen, likely to influence future production models.
