2015 Nissan GT-R updated with new lights, more refined ride

The Nismo version of Nissan's high-tech supercar may be getting most of the headlines today, but we shouldn't forget that the car on which it's based, the garden-variety GT-R, has been significantly updated for 2015, as well.
What Nissan engineers focused on for the new model year was making the GT-R a more well-rounded GT car. That means dialing some more compliance into the car's very firm suspension for a more comfortable ride, as well as lightening up the steering at low speeds to make urban maneuvering easier. The braking calibration has also been changed to be more linear and smooth when slowing from normal, everyday speeds. Does this mean the GT-R has gone soft? We'll reserve judgment until we drive it, but Nissan claims the new refinements giving the car "multi-dimensional performance."
The GT-R also gets new lighting technology for 2015, including multi-LED headlights that lend the car a new light signature at night, and the LED taillight rings are now complete circles instead of rings of dots. The headlights are also now controlled by an Adaptive Front Lighting System, which sounds similar to other systems that aim light where the car is being turned, but Nissan's system adjusts the angle of the lights depending on vehicle speed - at higher speeds the lights are angled to project their illumination further.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Nissan's Nismo celebrates 30th year with video retrospective

Nismo, the motorsports and high-performance arm of Nissan, has a lot of racing success to celebrate in its history and possibly even bigger accomplishments to look forward to. The company is commemorating its 30th anniversary with a video looking back at its most important milestones from each year of its past.
Nismo's job first and foremost at its genesis was to excel at motorsports. It wasn't too long after the division was founded in 1984 that the company made its first of many attempts to take an overall victory in the 24 Hours of Le Mans. It never quite succeeded in that goal, but still managed to do well in long-distance competition elsewhere. At the same time, Nismo was racking up wins in touring car races in Japan.
Eventually, the division's engineers started dipping their toes into tuning road cars, in addition to going racing. What began as something sporadic has become a growing part of the Nissan lineup with Nismo-branded models of the 370Z, Juke, Note in Europe and the GT-R.
