Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Altima Coupe dead as Nissan charts the changes for 2014

The 2014 model year brings plenty of new designs and updates from Nissan - including the next-generation Rogue - but the Altima Coupe has been discontinued. The current generation of the Coupe won buyers over with sharp styling and, at one point, a 270-horsepower naturally aspirated V6 - the heart of the more upscale Infinity G37. It's unlikely that Nissan plans to make another one, but keep in mind the current Coupe was released to the public about a year after the sedan hit dealerships.
The vehicles joining Nissan's lineup for 2014 include the Versa Note hatchback, the NV200 Compact Cargo van and the next-generation Rogue compact SUV. Also new for 2014 is the Pathfinder Hybrid, but that will be added to the lineup in the fall.
Other models that are receiving enhancements are the sedan version of the Altima, which now comes standard with the CVT transmission and gets revised option packs; the Frontier, which gets updated option packs, enhanced navigation system functionality and a sliding middle rear window; the GT-R, which receives a bunch of small performance enhancements and, more importantly, initially will be offered in three versions (Premium, Black Edition and Track Edition), with another, limited special-edition model coming late in the year; the Versa sedan, all versions of which get 60/40-split fold-down rear seats and revised steering and suspension tuning; and last, but not least, the 370Z NISMO will have exterior accent color updates and a new steering wheel and tachometer.

Nissan promising autonomous car production by 2020

Nissan will bring the autonomous car to consumers by the end of this decade. The announcement was made by CEO Carlos Ghosn at the company's US headquarters in Irvine, CA. Nissan has already begun construction of a dedicated proving ground for the self-driving cars in Japan, with completion targeted for the end of 2014.
Teaming with MIT, Stanford, Oxford and others, Nissan has already outfitted Leaf EVs with the Autonomous Drive (Nissan's brand name for the tech), a suite of new technologies developed from the brand's existing Safety Shield technology. The current iteration of Autonomous Drive uses the Around-View Monitoring system and laser scanners to analyze the environment, while artificial intelligence systems have been installed to help navigate and operate in a changing environment.
While it's easy to say that Nissan will bring the technology to market within the next six or seven years, it's more difficult to say at what price Autonomous Drive will be available. Most remarkable about all of this is Nissan's claim that self-driving cars will be both commercially viable and available at "realistic prices for consumers." It's expecting Autonomous Drive to be available across its range within two vehicle generations.
