Norwegian winter proving too much for some Tesla charging cables

Polar vortex 1, Tesla Model S 0? Possibly. Norway is certainly a long way from the sunny California climes where the luxury electric vehicle is made and, while the cars are popular in that country, the country's cold weather is creating problems for car owners, the Norwegian website News in English reports. As winter has set in, a number of Model S owners are reporting charging problems. One driver was stranded with a dead battery on Christmas Eve, while others have said Tesla's recharging cables are having a hard time holding a charge when the temperature gets substantially below freezing levels. Tesla has acknowledged that Norway has a different kind of electric grid than the US (and not just because it's 99 percent hydro-powered) that could be causing the problem. The company has reportedly sent Norwegian owners country-specific updates for the on-board recharging software. Once charged, the Model S works just fine in Norway. In this December video, posted by Norwegian Model S owner Bjorn Nyland, a Model S manages to drive for about 233 miles on a single charge in temperatures that reached only about 21 degrees Fahrenheit, and even then the car had about another 25 miles worth of juice left. Tesla has been well-received in Norway in part because of extensive government incentives as well as perks such as bus-lane access and free parking.

Ford Mustang Mach-E fails Sweden's moose test

The infamous moose test has claimed another casualty. This time it's the Ford Mustang Mach-E AWD Long Range, which was tested in an electric four-way alongside the Tesla Model Y, Hyundai Ioniq 5 and Skoda Enyaq iV (an electric utility vehicle closely related to the Volkswagen ID.4 that is sold in the United States). According to the Swedish testers at Teknikens Varld, Ford's electric car not only failed to hit the speed necessary for a passing grade, it didn't perform well at slower speeds, either. To pass the outlet's moose test, a car has to complete a rapid left-right-straight S-shaped pattern marked by cones at a speed of at least 72 km/h (44.7 miles per hour). The test is designed to mimic the type of avoidance maneuver a driver would have to take in order to avoid hitting something that wandered into the road, which in Sweden may be a moose but could just as easily be a deer or some other member of the animal kingdom elsewhere in the world, or possibly a child or car backing into the motorway. Not only is the maneuver very aggressive, it's also performed with weights belted into each seat and more weight added to the cargo area to hit the vehicle's maximum allowable carrying capacity. The Mustang Mach-E only managed to complete the moose test at 68 km/h (42.3 mph), well below the passing-grade threshold. Even at much lower speeds, Teknikens Varld says the Mach-E (which boasts the highest carrying capacity and was therefore loaded with more weight than the rest of the vehicles tested in this quartet) is "too soft in the chassis" and suffers from "too slow steering." Proving that it is indeed possible to pass the test, the Hyundai and Skoda completed the maneuver at the 44.7-mph figure required for a passing grade and the Tesla did it at 46.6 mph, albeit with less weight in the cargo area. It's not clear whether other versions of the Mustang Mach-E would pass the test. It's also unknown if Ford will make any changes to its chassis tuning or electronic stability control software, as some other automakers have done after a poor performance from Teknikens Varld, to improve its performance in the moose test.

Silly dyno, that Tesla doesn't have 2,000 lb-ft of torque

Torque. Lots of torque, right off the line. That one benefit presented by an electric motor over its internal-combustion sibling, and the Tesla Model S delivers it in spades. 443 spades, to be precise, or about as much as a Bentley Continental GT or McLaren 12C. But when one Emmanuel Chang put his electric sedan on a dyno up (way up north) in Edmonton, Alberta, it registered a whopping 2,000 pound-feet!
Of course that number isn't correct, as no car on the road produces that much torque. Even a Bugatti Veyron produces "only" 1,000 lb-ft, give or take. Clearly something's amiss here, but the problem the dyno had in reading the Tesla's torque apparently doesn't come down to its electric powertrain. (Nor does it have anything to do with the northerly latitude or the interference of polar winds.) It comes down to the shiny, ten-spoke alloys.
Apparently this type of dyno measures torque by running horsepower and wheel revolutions through an algorithm. It measures horsepower at the wheel (which, at 436 hp, wasn't far off of Tesla's own rating of 416 hp) and uses a stationary optical sensor interfacing with a reflector on the wheel. Every time the reflector passes the sensor, it counts one revolution. But since the Model S has shiny ten-spoke wheels (and we presume because it was taken outdoors under bright sunlight), the sensor thought that each passing spoke was one revolution of the wheel... when it was, in fact, ten times too much.
