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.

Recharge Wrap-up: Mercedes gets F1 efficiency, EV charging in Vermont, VW e-Golf to use Bosch

Efficiency equals performance, especially in the case of Formula 1 racing. The Mercedes AMC Petronas team points to several key efficiency technologies it uses to get the most out of its cars. And if their utter dominance so far this season is testament to this relationship, perhaps we should pay attention. Mercedes highlights hybrid tech, turbocharging, aerodynamics, lightweight construction, tribology (both in making internal components and lubricants more slippery) and simulation as crucial to getting around the track faster than anyone else. These just happen to be some of the same things that make the cars we drive on public roads more fuel-efficient. Learn more in the press release below. It's a good read. Brammo, maker of sweet electric motorcycles, is teaming up with TEAM Industries to make drivetrains for electric vehicles. TEAM, which specializes in drivetrain technology, will also become an investor in Brammo as part of the partnership. "The electric vehicle market is a growth market," says TEAM CEO and President David Ricke, "and TEAM and Brammo will be providing a wide range of solutions for OEM manufacturers." Read more over at EV World. Vermont celebrated the installation of a new EV charging station as part of a Green Energy Corridor between Boston and Montreal. When finished, drivers will be able to make the whole trip in an EV with access to charging along the way. For $5, customers can charge their vehicle in about 30 minutes at the Red Hen Baking Company in Middlesex. There are currently only about 700 EVs on the road in Vermont. The state has a goal to get 90 percent of its energy from renewable sources by 2050, and getting more EVs on the road is crucial to that mission. Vermont hopes that expanding the charging infrastructure will convince more people to go electric. Read more at Vermont Public Radio's website. For it's new e-Golf, Volkswagen will use Bosch chargers for home installation and ChargePoint stations at its dealerships. Bosch will have various 240-volt options for the home, and will also provide installation. e-Golf customers will also get a free ChargePoint membership, and will have access to the company's network of charging stations worldwide. The 2015 e-Golf goes on sale in the US later this year. Read more in the press release below.

UK workers strand car on island of asphalt to keep working

Generally speaking, when you illegally park your car, you're likely to get ticketed and towed, but there is probably at least one motorist in Scotland who wishes that was the case. After workers had blocked off a portion of the parking lot for the Edinburgh Waverley railway station, the driver of this Mercedes-Benz S-Class reportedly moved some of the barriers to park in one of the empty spots.
Rather than having the vehicle towed, the work crew simply tore up the asphalt around the leaving just the one parking spot intact, and as you can see in the image above (posted to the Twitter account of Harold Norstad), the crew even built a small asphalt ramp so the car could get off its blacktop pedestal. Since this happened last week, there's no word as to whether the car was eventually moved or towed for the resurfacing work to continue.
Let this be a warning...
