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.

This tiny 1.5L engine from Nissan makes 400 horsepower

Back in 2012, Ford packed its tiny 1.0-liter EcoBoost three-cylinder in a carry-on suitcase, destined for use in the Fiesta here in the US. In June, Nissan will pack its tiny new three-cylinder engine in a 24 Hours of Le Mans racecar. Nissan's don't-call-me-DeltaWing ZEOD RC racecar will still be able to tackle a single lap under full electric power, but the rest of the time it will be powered by the new 1.5-liter turbocharged three-cylinder engine.
Holding the lightweight engine (at right) is Nismo president Shoichi Miyatani, and he's likely smiling because that 40-kilogram (88-pound) engine packs quite a punch with 400 horsepower and 280 pound-feet of torque. Nissan would like to take a moment to point out this engine's power-to-weight is better than the engines currently used in Formula One racecars. Scroll down for more information on this new race engine, which we'll see in action at Le Mans in June.

China's largest dealer body pushes back against foreign automakers over huge inventories

Do not think for a second that automakers forcing inventory on dealers in order to pad the numbers is a ruse known only in the US. Stories of individual brands have hinted at the trouble Chinese dealerships are having trying to move units as the country's economic growth remains hot but comes off the boil, like the one revealing that 95 percent of Toyota-FAW showrooms are losing money. Yet Toyota isn't the only culprit, and the issue has become so dire that the China Automobile Dealers Association (CADA), the largest dealer body in the country, has written to the government to complain. Chinese car sales are expected to close out the year with an annualized growth of six-percent, down from last year's 14 percent when targets were set, while in the background the pace of overall economic expansion is the slowest its been since the early nineties. Automakers, shipping cars on schedule to make their earlier targets, have blown up inventories such that they are an average of 1.8 times monthly sales, when the preferred multiplier is from 0.9 to 1.2. According to the CADA, the price wars and necessary incentives mean that only 30 percent of dealers are operating in the black. That number is down a whopping forty percent since 2010. In response, Toyota has already said it will not make its 2014 target of 1.1 million cars sold. We're a long way from 2012, when Toyota planned on selling 1.8 million cars in China in 2015, a target that's now as realistic as a manticore. BMW, Honda and Nissan have erased numbers on their spreadsheets, too; BMW growth dropped from 20 percent to 8 percent midyear after it began "reducing wholesale supplies," and Honda has been reworking its plans as sales have decreased each of the past six months. It's a big deal for Chinese dealers to begin protesting publicly, the CADA saying, "In the past, dealers were angry, but dared not speak out. But now, they have to shout because the situation is getting so unbearable." With six-percent growth forecast for next year and dealers unwilling to remain underwater, The Year of the Sheep coming in 2015 could portend meaning beyond the zodiac.
