The Leaf, which hits European and U.S. showrooms in December, best exhibits the new look. The front headlamps stick up like raised welts and follow the fender crease almost to the front roof pillars. Turn indicators on Nissan's upcoming Juke crossover get similar treatment.
The style improves aerodynamics and reduces wind noise, but that's not all. "This gives us more design freedom," Nakamura said. Disconnecting lamps from the body contour, for example, allowed Nissan to lower the hood on the Leaf while keeping the lights high.
At the same time, Nissan is paying more attention to the rear end, where rear lamps are evolving into spoilers to help control air flow, Nakamura said. The taillamps on the latest generation of the Infiniti M protrude slightly to create a squared end that helps reduce drag.
The M also gets a pronounced ducktail spoiler that further improves handling and air flow.
The next-generation Infiniti G will follow in the M's steps with a stronger, more defined grille, a sportier, slicker tail and lamps with more character, Nakamura said.
Separately, Nakamura says the company is exploring new segments for Infiniti, which now relies on big sedans and large-sized crossovers and SUVs.
"Probably we need a little bit more in the lineup for Infiniti, new models," Nakamura said. "We need some additional variation to get a larger customer base."
He didn't give details but said going smaller was not the only option.
When it comes to the Nissan brand's core lineup of sedans, Nakamura aims to give them more enhanced grilles and more upmarket surface treatment for a stronger brand image.
The objective is to allow models such as the Altima to do better against the likes of the Honda Accord and Toyota Camry. For the first three months of the year, U.S. sales of the Altima rose 20 percent to 59,483 units, making it Nissan's best-selling model in the country.
But the Accord racked up sales of 72,335 units, while Toyota moved 68,595 Camrys.
"We don't want that to stay as it is," Nakamura said. "Sportiness and modernity" are key, he said.
Watch for an evolution of the front end, Nakamura says. While Nissan's styling in the United States is unified, he says it needs to express a more unique Nissan identity.
"I would like to put a more pronounced treatment of the front end," Nakamura said, "starting with the next-generation Altima, Sentra, those cars. We will renew the whole sedan lineup."
