Top 10 small cars with the longest total driving range

Editor's Note: Since this article was originally posted in the spring of 2015, much has changed in the automotive landscape, especially among those shopping for small car economy. With thanks to Volkswagen for their blatant cheating – and subsequent cover-up – on diesel emissions, the largest player in the diesel passenger car segment isn't playing – they're paying; billions are going for both car buybacks and federally-imposed penalties. And for a few VW execs there exists the very real possibility of jail. With the absence of a big player and the abrupt entrance – via Chevy's new Bolt – of an affordable EV with 200+ miles of range, we've limited the diesel listings to Jaguar's new XE. And for those wanting an updated look at efficiency and range, Autoblog has it – or the EPA has it. Long before electric vehicles were part of the mainstream conversation, car lovers and skinflints alike would boast about the total range of their vehicles. There's something about getting farther down the road on one tank of gas that inflames the competitive spirit, almost as much as horsepower output or top speed. Of course, the vehicles with the very best range on today's market are almost all big trucks and SUVs; virtually all have the ability to carry massive reserves of fuel. Top up a standard Chevy Suburban and you can expect to travel almost 700 miles (you'll need to stop before the Suburban stops...), while a diesel-fed Jeep Grand Cherokee manages almost as many. But what about vehicles that are smaller? The EPA has, essentially, three classifications for 'small' vehicles: Minicompact, Subcompact and Compact. All three are measured based on interior volume, meaning that some cars with rather large exterior dimensions and engines slot in next to traditional small cars. But even though impressive GT coupes from Porsche, Bentley and Mercedes-Benz may have much larger gas tanks to feed their powerful engines, that capacity is offset by higher rates of consumption... in most cases. We used the EPA's Fuel Economy Guide for model year 2017 cars as a start, calculating the official highway miles per gallon rating with each vehicle's tank capacity. The resulting numbers aren't necessarily real world, but they do offer a spectrum for total theoretical range. The eventual top ten surprised me on a few occasions, and comprised quite a varied list of vehicles. 10.

VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

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.
