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.

Elon Musk wants to build an Internet in space

The next James Bond film is called Spectre; if the villainous mastermind driving that Jaguar C-X75 isn't named Elon Musk, we'll want to know why not. The real-life Musk isn't evil so far as we can tell, but we gotta say he's just as ambitious as Ernst Blofeld ever was. While opening a SpaceX office in Seattle, the face of Tesla said that the engineers and software programmers in the Pacific Northwest outpost will be working on "a global communications system that would be larger than anything that has been talked about to date" on top of their Falcon rocket and Dragon capsule duties. Musk's idea is that hundreds of satellites in low-Earth orbit would get information around the world much faster, and be provide better Internet service for "people in sparsely populated areas." Once the folks in the terrestrial hinterlands are taken care of, Musk envisions the network providing the foundation for a satellite network that would provide Earth-to-Mars communications to the Mars-based colony that the SpaceX CEO expects will wear company branding. The idea isn't new - one of Musk's peers is working on the same concept, backed by Qualcomm and the Virgin Group. But Musk says that OneWeb, the competitor, has a different concept for the underlying architecture and that his satellites would be "an order of magnitude more sophisticated." If you're trying to figure out what the area code to Mars is, you're way ahead of things: Musk says the terrestrial satellite system won't be ready for at least five years. And since the average distance to Mars is 140 million miles, it'll probably be a few years after that before you can shoot a text to the Spirit and Opportunity rovers.

Pininfarina teases its Tesla- and Bugatti-baiting EV supercar

Pininfarina isn't being bashful when it comes to getting into the car business. The Italian design house has revealed a sketch of the PF0 Concept, an electric supercar aimed directly at the world's fastest and most expensive vehicles. With upward of 1,000 horsepower, along with an expected price in the millions of dollars, this extreme EV is meant as a calling card for Pininfarina's upcoming range of electric cars and SUVs. So should the likes of Tesla, Porsche, Ferrari, Bugatti and Lamborghini be worried? Pininfarina might be new to building its own cars, but the company has many decades of experience designing and engineering some of the most desirable cars of all time — including many of the finest supercars to have worn a Ferrari badge on their nose. As we reported earlier this year, Pininfarina has teamed with Indian auto manufacturer, Mahindra, to develop a range of high-end EVs. With this roughly $500 million investment, not to mention some engineering help from Croatian supercar manufacturer, Rimac, Pininfarina aims to start high. The company will first introduce a hypercar, based on the PF0 Concept, within two years, then bring along a range of more affordable electric cars and SUVs. These will more directly take on the likes of Porsche Cayenne, Lamborghini Urus, and Tesla Model X. So yes, if you're in the business of building expensive cars, especially ones with a lot of batteries positioned inside them, Pininfarina's plans for the PF0 (that's a zero, not the letter "O," by the way) should make you sit up and take notice. "Automobili Pininfarina is a pioneering new business created to service the most discerning clients in the world," said Michael Perschke, CEO for Automobili Pininfarina. "Our product portfolio will launch with an innovative, zero-emissions hypercar that represents the progression we aim to make at the pinnacle of the luxury and sports car market." According to its press release, Pininfarina is currently presenting its "business and product plans to prospective retailer partners, clients and media in New York this week." After its tour of the Big Apple, look for Pininfarina to officially reveal the PF0 Concept during Monterey Car Week in August.
