How to get incredibly accurate information on your EV's charging power

One would think that paying about $300 to receive a bit of bad news about electric-vehicle charging would be counterproductive. But the fine folks at Teslarati believe that truth is beauty, and they're willing to pay a little extra for the straight dope. There are always losses when taking power from the grid and shoving it into an EV's battery pack. The question is how big are these losses. Teslarati calculated digital read-outs from the dashboard of their Tesla Model S all-electric sedan and found that Tesla builds in about a nine percent efficiency loss when it comes to recharging the car. But the blog thought the Tesla couldn't know exactly what was transpiring between the wall and the battery, so it footed the bill for about $300 to install a digital submetering unit from EKM Metering. With a little calculation, Teslarati was able to figure out after a couple of recharging rounds that the efficiency loss per recharge was closer to 15 percent than nine percent. That means that, instead of paying about 48 cents on the dollar relative to filling up an economy car (factoring in the AAA average price of $3.66 per gallon), Tesla owners are paying about 52 cents on the dollar. Not much compared to paying upwards towards $100,000 for the vehicle itself, but, hey, every cent counts, right? Get all of the details here.

Fiat Chrysler’s Sergio Marchionne throws more cold water on Tesla, EVs

Fiat Chrysler CEO Sergio Marchionne has once again sounded off on industry upstart Tesla and its wunderkind boss, Elon Musk. In the process, he doubled down on FCA's reluctance to follow its competitors headlong into electrifying its vehicle fleet, saying "we're not betting the bank on going fully electric in the next decade. It won't happen." Marchionne made his comments on Monday during remarks at the New York Stock Exchange, where he was marking the 70th anniversary of Ferrari. They come as Tesla struggles to ramp up production of its Model 3 sedan, its first mass-market offering, and the company continues to hemorrhage money. Here's what he said: "We still don't have a viable model for delivering an electric car. As much as I like Elon Musk, and he's a good friend, and actually he's done a phenomenal job of marketing Telsa, I remain unconvinced of a new economic viability of the model that he's pitching. So I think we need to be careful, because when we embrace electrification, and I made comments on the fact that we lose money on every Fiat 500, the electric that we sell in the U.S. Now that's reflective of the 2011-2010 costs in terms of components. Those costs have come down. If I were to do it again, I would certainly reduce the amount of the loss, but I would not make any money. And you can't run economic entities on losses. It doesn't happen. "So how do we find a convergence of technology bringing prices of components down and allows us to price accordingly — or we need to navigate through this process in a combined way between combustion and electrification to yield at least a minimum of economic returns that allows for our continuity? The last thing you want is me to be successful selling cars for 24 months and then go bust. That's not a good story. Especially in a place like this which rewards economic success. Let's not sit here and design our own future in the tank. Let's try and do it properly. We will do all the right things. We are investing without making a lot of noise on electrification. We will combine it with combustion to yield the right level of CO2. But we're not betting the bank on going fully electric in the next decade. It won't happen." It's not the first time Marchionne has publicly expressed doubts about Tesla's business plan.

AAA ranks Tesla Model S P85D best green car of 2015, Versa is best value

Reviewers from all parts of the automotive world just seem to love the Tesla Model S, whether it's the pragmatists at Consumer Reports or the enthusiasts at Car and Driver. You can add one more to that list because the 2015 P85D grabs the top spot in AAA's fifth annual Green Car Guide, after Tesla's win last year too. The organization's ranking of 88 green models also names the 2014 Nissan Versa SV as the best value in the segment. To take the victory, the P85D had to score the most points over 13 categories, including emissions, acceleration and cargo capacity, and it won handily with 94.87 points. There was nearly a tie for second place, though. The 2015 Volkswagen e-Golf SEL Premium scored 85.5 points, and the 2014 BMW i3 narrowly came in third with 85.4. The best value award is based on the as-tested price per point scored. So while the Versa SV only had 64.5 points overall, its low price meant that each one cost just $249. Second place went to the Versa Note SV with 64.63 points at $260 each, and third was the Hyundai Accent GLS with 61.1 points for $269 each. Keep in mind, AAA's ranking doesn't attempt to find the most environmentally friendly vehicle, rather it tests the green car segment to give recommendations to buyers. Battery electric powertrains, compressed natural gas, clean diesel, hybrids, partial zero-emissions vehicles, and simply models with high fuel economy are all counted by the organization. The results are published in a 160-page magazine, which you can read here. It also offers suggestions on economical driving and explains some of the fuel-saving tech currently available.
