Green Options

Editor’s Note: This is part four of an exclusive sit down I had with Hideaki Watanabe, Nissan’s Division Manager of their Global Zero Emission Business Unit, at last week’s U.S. debut of the LEAF in Los Angeles. Part one is devoted to battery swapping, part two to battery leasing, and part three to the quietness and safety of EVs.

During the Frankfurt Motor Show in September, Renault invited Gas 2.0’s own UK-based Chris Milton to an exclusive event detailing the company’s electric car strategy. The event introduced some rather quirky (and quirkily named) electric cars, including the Twizy, the Kangoo, and the Zoe. These aren’t just concept cars, they are cars that Renault intends to build and sell—some by next year.

Based on those releases—and the fact that Nissan hasn’t invested anything in battery swapping while Renault has jumped in head first—it started to seem that the Renault-Nissan Alliance was taking two completely different paths on the road to EV world domination. On the one hand you have Nissan with the rather mainstream-looking LEAF and plans for a luxury Infiniti electric car. And on the other you have… the Twizy.

In my recent sit down with Hideaki Watanabe, Nissan’s Division Manager of their Global Zero Emission Business Unit, I asked him to explain why Nissan and Renault were apparently moving in opposite directions.

Nissan CEO Carlos Ghosn made it a point to highlight how quiet the upcoming Nissan LEAF electric car will be during an event in Los Angeles last week to mark the car’s U.S. debut. “LEAF has no engine, no tailpipe, no fuel tanks,” he remarked. “As a result LEAF has zero carbon emissions, zero particle [emissions] and zero noise. It’s quiet and clean.”

The gathering crowd of electric car makers has been drumming this “quiet mantra” since day one, and, indeed, it is certainly a great selling point. But recently the quietness of EVs has come under scrutiny as a potential safety hazard to the blind, the elderly, and children; if you can’t hear the car, it’s one less warning you have of an impending accident.

One of the things people who’ve driven electric cars seem to enjoy (including myself) is the complete silence of the electric motor. The only noises you hear while driving an EV are dependent on how fast you’re driving, the kind of tires you have, and the condition of the road. For a commuter, this feature alone can be worth millions in sanity.

But at low speeds while driving around town, EVs represent a bit of a threat to people who aren’t able to pick up on the visual cues of such a silent car — namely the visually impaired, children and the elderly. In an effort to address this problem, Nissan has decided that at speeds under 12 mph, the upcoming LEAF EV will emit a “beautiful and futuristic” noise reminiscent of the sounds that flying cars emit in sci-fi movies such as Blade Runner.
