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.

2013 Nissan Frontier gets substantial price drop, better fuel economy

With the competition dwindling (or dying) among compact trucks, Nissan is looking to make some minor changes to the 2013 Frontier to snag a few extra sales for its aging pickup. Pricing and fuel economy are probably two of the most important vehicle stats among new-car buyers, and the 2013 Nissan Frontier has made vast improvements in both areas over the 2012 model.
First things first: The MSRP of both the King Cab and Crew Cab models have dropped by $1,270 with new starting prices of $17,990 and $22,030 (*not including the $845 destination charge), respectively. The biggest price drop is seen on the SV Crew Cab 4x2, which dropped $1,450 to its new price of $23,990. The important thing here is that the 2013 Frontier King Cab is now priced just a few hundred dollars more than a regular cab version of the Toyota Tacoma. Nissan is also offering a new SV Value Truck Package that includes all the equipment of the previous SV Premium Utility Package (spray-on bedliner, Utili-Track in-bed cargo system with four adjustable cleats and Bluetooth) and adds in a rearview monitor and dual-zone air conditioning.
Another key change made for 2013 was to the Frontier's fuel economy. Except for the base-model truck (King Cab, inline-four, manual transmission, two-wheel drive), all other configurations have seen increases in city and/or highway fuel economy to the tune of one or two miles per gallon; the biggest improvement was to the V6 models with the automatic transmission, which saw an improvement of one mpg city and two mpg highway. Nissan accomplished this with better aerodynamics and updated internal engine components to reduce friction. Aero changes include a seal between the cab and bed, a tailgate spoiler and a new front chin spoiler.

Nissan alters all CVTs to act less like a stretched rubberband

Among automotive enthusiasts, no one seems to hold a neutral opinion when it comes to continuously variable transmissions. CVTs are either praised for their ability to boost fuel economy or chided for their occasionally poor driving dynamics. Nissan is among the masters of these un-shifting gearboxes in the US, and it uses them in many vehicles in its lineup. However, for the 2015 model year, several models are getting a software update to make their CVTs a bit more like a conventional automatic.
To give drivers the option of feeling gearshifts while on the road, Nissan is adding its D-Step Shift Logic feature to the CVTs in multiple vehicles. Steve Powers, Nissan's senior manager of powertrain performance, told Autoblog the system forces the transmission to "hold a ratio and then shift" to simulate the way that a traditional automatic would. It's simply a change in software, but the company "can't do it to older CVTs," he said, because it would require changes to transmission logic, as well. According to Automotive News, the upgrade is coming to the 2015 Versa, Versa Note (pictured above), Sentra, V6-equipped Altima, Pathfinder and Quest. "We're rolling it out to all programs," said Powers.
Interestingly, buyer perception appears to be pushing the upgrade. John Curl, a Nissan North America regional product manager, told Automotive News that the decision to add the tech partially comes because some owners are bothered that the CVTs aren't changing gears. According to Powers, D-Step "avoids the rubber band feel," that many drivers didn't like. The different sensation of these transmissions seems like something consumers would notice during the test drive, or that the salesperson would inform them about. The same issue cropped up last year when the company was facing customer satisfaction problems among new buyers customers' unfamiliarity with the gearboxes.
