Porsche Panamera designer focused on rear-seat passengers

Styled by a team of in-house designers under the direction of Michael Mauer, the Panamera is 195.7 inches long, 76.0 inches wide and 55.8 inches tall--making it slightly shorter but wider and lower than the Maserati Quattroporte, with which it shares a coupelike profile. As with all such silhouettes, "the real challenge is giving the rear-seat passengers enough headroom," says Mauer.
