Panoz mulls suing Nissan for ZEOD RC's Deltawing likeness

Imitation might be the sincerest form of flattery, but in racing, where something as simple as a car's shape can lead to a competitive advantage, imitation can be a big no-no. That reality is being played out right now, with the DeltaWing prototype and the Nissan ZEOD RC. The two cars, as you can see from the images above, bear a striking resemblance to each other. They're so similar, in fact, that Dr. Don Panoz, one of the big names behind the DeltaWing program, is assigning some legal eagles to investigate any patent infringement.
The similarity shouldn't be a shock, though. Both cars are penned by Ben Bowlby, and the DeltaWing - which will be arriving as a coupe in the very near future - had Nissan branding and power for a not-insignificant amount of time. But for Panoz, the ZEOD RC's resemblance is just a bit too much, as he told Autoweek, "It's been interesting to watch people from Nissan trying to dodge the question, but the fact is that in their own press release they admit that the configuration of the ZEOD is the same as the DeltaWing. And we do have patents, in fact another one was just issued last week. We are in discussions with our legal advisors and we'll see what happens."
Frankly, it's not difficult to see what Panoz means. The general shape of the ZEOD RC, with its wide rear track and narrow front track arrangement - not to mention the headlights mounted over the rear wheel arches and any arrangements not visible under the body - are so reminiscent of the DeltaWing that differences like the shape of its closed cockpit and more upright front end might not prove different enough to avert Panoz's legal action. We'll stay with this one and let you know as more becomes available.

Nissan VP suggests next Z will offer multiple engines

Roel de Vries, the corporate vice president and global head of marketing and brand strategy for Nissan, told Australia's CarAdvice that as far as he's concerned, any engine in the 370Z "[needs] to deliver on what the car stands for and if the 370Z stands for real performance and real driving I think it doesn't need a V6 to do that." At first read, it could look like de Vries is softening us up for a next-generation Z that doesn't come with a V6, a move that would disappoint a lot of the coupe's fans. Or, what if de Vries was actually getting us ready for a Z with multiple engine options, instead of only a V6, in order to expand its global appeal? That appeared to be the gist of his comments, the exec saying that they couldn't sell a V6-engined Z in Europe, but even if they offer a four-cylinder there, the V6 could live on because, "why should we give it up?" With the coupe's current name a factor of the 3.7-liter displacement of it's V6, though, what is the future for a car with several engine options? Said de Vries, "We [will] definitely keep the Z name, but when we did 350 to 370 it was because of the capacity, but who says the next-generation doesn't have three engines and its not just called Z?" This kind of talk has been going on all year, the real question being how many engines will the car get and what's the endgame. At the beginning of the year, ex product chief Andy Palmer said the car codenamed Z35 would use a "downsized four-cylinder turbocharged engine." In August, Motor Trend reported that the next Z would offer "a mixture of smaller but powerful engines," including a hybrid, but that a V6 would remain the headliner. Two weeks later, MT said that Nissan wanted to transition customers from the naturally aspirated V6 to a turbocharged four-cylinder with the same power, eventually, but would begin with both on the menu. Parallel to that are Shiro Nakamura's out-loud musings about how to merge the next Z and the IDx concepts into "a more affordable, more approachable sports car." The answers, whatever they are, will be a big deal for the brand.

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.
