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.

Nissan Rogue gives brand rare monthly sales lead over Honda

The five top-selling brands in the automotive industry are usually Ford, Toyota, Chevy, Honda and Nissan, in that order. This lineup emerged intact when counting a year's worth of sales for 2013, and there was no reason to expect it would change at the beginning of 2014. But it did. Thanks to surging sales of its all-new Rogue, Nissan managed to pull ahead of Honda to become the fourth best-selling auto brand in January 2014, selling 81,472 units (an increase of 10.41 percent compared to January 2013) to Honda's 80,808 (a decrease of 3.96 percent).
The Rogue led the way for Nissan, contributing an additional 4,880 units in January compared to the same month last year - a 54.5-percent increase for a grand total of 13,831 units. But the Rogue had help, with the Frontier pickup adding an extra 2,307 units (an 87.9-percent increase), the Juke an extra 1,081 units (a 45.8-percent increase), the Altima an extra 1,051 units (a 4.9-percent increase) and the Maxima an additional 983 units (a 32.9-percent increase). Honda, meanwhile, was hurt by falling sales of the Accord (down 13.9 percent) and Pilot (down 7.6 percent), and stagnant sales of the Civic.
Honda, however, should take pride in the fact that it's luxury division, Acura, outsold Infiniti, Nissan's luxury division, last month - 10,823 units sold to 8,998. That margin of victory was large enough to keep the parent company of American Honda ahead of Nissan North America for the month of January.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.
