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.

Renault planning a Tata Nano rival. Again.

Four years ago, Renault confirmed that it would partner with India's Bajaj Auto to develop a rival to the Tata Nano. At the time, as everyone waited for the Tata Nano to arrive, you could have used a Richter scale to measure the tremors the executive suites of any automaker with an interest in the low end of emerging markets. Then the Nano, still the cheapest car in the world, didn't sell so well - at the end of last year its sales were just six percent of its most conservative projections - and everyone seemed content to let Tata spend the money to figure out if there really was a market for the cheapest car in the world.
Renault believes there is, kind of. Automotive News Europe reports that it will partner with Nissan to build two low-priced cars for emerging markets, one for €3,000 ($3,888 U.S.) and another for €5,000 ($6,400 U.S.). The price of the least expensive offering is nearly $1,400 more than a Nano, which costs $2,500, and that can't be considered a small sum in comparison. But one of the hindsight knocks on the Nano has been that even in emerging markets buyers don't want a car whose biggest lure is that it is cheap; they'd rather give their aspirations a bit more of a workout.
Renault's offerings are scheduled to hit the non-Western market in late 2014, which is coincidentally the same year that will see the return of the budget-minded and emerging-market-specific Datsun nameplate. They'll be built in Renault facilities in Chennai, India, with no mention made of Bajaj this time around.
