Where is Nissan and Infiniti design headed? Just look at the lamps

For a glimpse at future styling trends from Nissan Motor Co., look to the headlamps on the Nissan Leaf electric car and the sculpted rear of the Infiniti M. Front and rear lamps raised from the body surface and pronounced spoilers are two tricks Nissan will use more often to improve the aerodynamics and handling of vehicles--in addition to giving them a futuristic flair, global design chief Shiro Nakamura says. The goal: Win young drivers and bring sales of models such as the Nissan Altima in line with Japanese rivals "The important thing is the front end and the rear end," Nakamura said during an April 12 interview at the company's main design studio south of Tokyo.
