Cadillac 2014 ELR [w/Gallery]

Cadillac unveils the 2014 ELR today at the North American International Auto Show. The new luxury coupe is almost unchanged from the Converj Concept - unveiled at the 2009 NAIAS - upon which it is based and features Cadillac's signature vertical headlamps and rear lamps. The flush fascia and grille – with active shutters behind the grille opening – combined with tapered fascia corners and a raked windshield mean that drag is reduced to 0.305.

Porsche announces new Weissach design center and wind tunnel

Porsche is to invest around €150m into its Weissach development facility, including a new design center. The plans also include an electronics integration department and a state-of-the art, on-site wind tunnel, which is hoped will allow the company to realize an holistic approach to efficient design, with a strong focus on aerodynamics. When we spoke with head of Porsche design, Michael Mauer, at this year's Paris motor show, he also alluded to the fact that the Volkswagen Group's – and, more specifically, Walter de'Silva's – recent influence on the German manufacturer was shifting its attitudes: "The Volkswagen Group has a very good understanding of how much freedom a brand needs to keep its characteristics and with [Walter] as 'conductor', I feel a lot of support with design issues within the company," explained Mauer.
