Video: Michael Mauer on the 991-series Porsche 911

Porsche has released a video featuring its Design Director, Michael Mauer, explaining how he and his team went about redesigning the 911, an ‘automotive, engineering icon' as he describes it. "What we as designers are striving to above all is to optimize the width to height ratio with the result that although the 911's width has not increased, the front axle area has become wider, and we've managed to make the roof a bit lower," Mauer explains via a rather dramatic-sounding voiceover.

Hyundai i30

Though CDN was invited to attend a preview of the all-new Hyundai i30 ahead of its official unveiling at the 2011 Frankfurt motor show, these are the only images we're able to show you of the Korean automaker's C-segment hatchback until next week. "Through the profile of the new generation i30, a strong character line runs over the front and rear wheelarches all the way to the tail lamps," says Thomas Bürkle, Chief Designer at Hyundai Motor Europe. "A softer, lower character line rises up the car's flank creating a play of light and shadow - a fundamental feature of fluidic sculpture." The next evolution of the current i30 will be shown alongside the new i40 saloon and the new 1+2 door Veloster coupe on the company's Frankfurt show stand, which is claimed to reflect Hyundai's new brand direction - 'New Thinking, New Possibilities'.
