Ghosn hedges Nissan's 2020 autonomous deadline

Three years ago, Nissan was one of the first companies to promise a hands-free autonomous car by 2020. According Nissan Chairman and CEO Carlos Ghosn, when and how much we'll be able to take our hands off the wheel depends on more than just the components in the car. At a press conference during this year's Frankfurt Motor Show, the head of the Renault-Nissan Alliance said, "No matter how fast the technology develops, the autonomous cars are very dependent on the regulation." Basically Ghosn is saying that Nissan will be ready, but the laws allowing hands-free driving might not be so prompt. "You can build a lot of autonomy, but if the consumer or the driver cannot enjoy it because he still has to have his hands on the wheel, he still has to have his eyes on the road, it just puts cost in the car without the benefit," said Ghosn. The overall tone of Ghosn's comments was that Nissan is ready for autonomous driving, but without clear laws there could be no point in offering the technology to consumers. Ghosn also clarified what autonomous driving means in Nissan terms, clarifying a statement last year where he said a consumer product is still a long way off. The company's three-step plan begins next year, "where you can be on the highway as long as you don't change lanes and you can be in autonomous mode." Then in 2018, these systems will be able to change lanes without human intervention. For the final step in 2020, "We're going to have cars capable in the city and on the highway to make more complicated operations [in an] autonomous way," said Ghosn. "That's why I think when you talk about autonomous cars, we have to be much more specific about what kind of autonomy are we talking about... but we maintain our forecast that is going to come in different waves, and we define our waves by the functionality of autonomy in our cars [in] '16, '18, '20." That said, don't skip your driver's license renewal five years from now. According to Ghosn, you won't see a Nissan without a steering wheel. That's both Nissan's goal, and the company's way around the lack of regulation on driverless cars. "Frankly, a car without a driver is not our priority... There is a driver, and we are putting some functions into the car, allowing the driver to drive when they want, and to stop driving when they want... These are the same pieces of technology, which in addition to others, can lead you to the car without the driver.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Nissan puts Le Mans prototype program under review

Nissan had a challenging time developing its GT-R LM Nismo, then it faced enormous challenges at Le Mans, the race it designed the car for, and now the race outfit is dealing with challenges in the boardroom. While the outfit gets ready for a test at the Circuit of the Americas, Sportscar365 reports that Nissan executives in Japan are deciding how to proceed with their LMP1 program. The meetings were presaged last month by CEO Carlos Ghosn, who said at last month's Formula E race in London that "we must assess the strategy. We wanted to be different and competitive, we have only been different." Both Ghosn's wording and that of the Sportscar365 piece make it seem that company bosses are wrangling over continuing with "the current specification" of the GT-R LM Nismo, not the entire two-year race program. If that's the case and the decision goes against, we could see a more traditional Nissan racer in La Sarthe next year. While it's easy for us to say this, we think that would be a shame. Le Mans is hard enough to win with a massive budget and a traditional race car - just ask Peugeot and Toyota, and remember that Porsche didn't go home covered in laurels its first year back, either. Given just how different Nissan's car is, a year in the deep weeds at the world's biggest and least forgiving endurance race against veteran competition isn't an outrageous outcome. And remember, persistent issues prevented the team from using the car's hybrid system, robbing the GT-R LM Nismo of half its horsepower and rear-wheel drive. That was never going to go well. Can the engineers get the GT-R LM Nismo to work properly? We don't know. But we'd like to see them get a proper chance to get it right. Related Video:
