The Scoot Quad is Nissan's small step toward EV car sharing

Halfway up Laguna Street, the panic set in. I might not make it up this hill. With my foot depressed all the way to the floor, I sucked in my stomach and started to pray. Yet again, I found myself in an unconventional way to get around on four wheels – but this time, I was on my own, and behind the wheel. Meet the Scoot Quad, aka Nissan New Mobility Concept, aka Renault Twizy. The many aliases reflect the path of descent from its development as a quirky French electric vehicle to its proliferation as a model for car sharing. The Quad resides in San Francisco as part of the Scoot fleet of shared electric vehicles and it's most certainly not for sale. As the line blurs between those who share cars for personal reasons and those who use them for business purposes, Scoot and Nissan came to an agreement in which a small number of New Mobility Concepts would join the Scoot fleet – which currently includes over 300 motorbikes. The added value of Scoot is the capacity for one-way rentals around the city, as well as a dedicated network of charging stations. "We think it's just the best way to get around the city for everyone," said Scoot fleet vice president Mike Waltman, explaining how 10 New Mobility Concepts made their way to San Francisco. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. The one-plus-one Twizy has been in production since 2012 and on sale in certain overseas markets, but it's entirely new for the United States, and it wears the Nissan badge here – kind of. No major changes were made to the Twizy when it became the New Mobility Concept, and similarly none were made in its "transformation" to the Quad. It sports the same insectile shape and the rear profile of a top hat, as well as an identical powertrain: a 13-kilowatt motor that produces 17 horsepower, routed to the rear wheels through a single-speed automatic transmission. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. Its top speed is 50 miles per hour, but Nissan installed a governor at 25 mph to conform to US low-speed vehicle requirements. New Scoot members are required to successfully pass an exam before beginning to use the service, so that was my first order of business. After spending about 35 minutes going through a series of informational videos on the Scoot app, as any new member would do, I was ready to ride Scoot motorcycles.

Weekly Recap: Chevy and Alfa plot comeback strategies

Chevrolet and Alfa Romeo were two of the 20th Century's most iconic automotive brands. Chevy embodied America's post-war power and confidence. Alfa was the definition of the stylish Italian sports car. They reached halcyon heights in the 1950s and '60s, before declining precipitously amid new competition, changing consumer tastes, and uneven corporate management. Both say 2015 is the start of something better, and this week Chevy and Alfa laid out ambitious plans and showcased new cars that they hope will make them more relevant this year, and in the coming years. Each brand sits at its own crossroads, and their paths forward are as different as the Chevy Cruze and the Alfa Romeo Giulia. Chevy is still a sales beast, as evidenced by its volume of 4.8 million vehicles sold around the world last year. Chevy executives are fond of saying one of their cars is sold every seven seconds, which illustrates the strength and reach of a car brand that is the fourth largest in the world. "Make no mistake about it, we are a brand for the people," said General Motors North America president Alan Batey. But he wants consumers to want to buy a Chevy for its design and technology, not simply because it's affordable. That starts with all Chevys now featuring a distinctive a family look, with sporty cues from the Corvette or strong lines that riff on the Silverado pickup. "We want people to fall in lust with our cars," said Mike Pevovar, executive design director for Chevy passenger cars. "That initial emotional attraction has to be right on the exterior, and that's where form comes into play." Chevy is also loading up its cars, like the freshly unveiled 2016 Chevy Cruze, with technology to appeal to a younger crowd that prizes connectivity. The Cruze will offer Apple CarPlay and Android Auto with its MyLink infotainment system, and OnStar with 4G LTE and wifi. Seeking out younger buyers is also sound business practice: Millennials now outnumber Baby Boomers as the largest single age group in the United States. Younger buyers also can improve a brand's image, which is another area where Chevy would like to improve. Chevy ranks 82nd on Interbrand's Best Global Brand's list, behind 11 other automakers. Apple is No. 1. "We need our own variation of the Genius Bar," Batey said. 2016 Alfa Romeo Giulia View 3 Photos Meanwhile, Alfa is in different shape.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
