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.

Project Maybach is an absurd, awesome off-road electric coupe

Mercedes has created some mighty unusual concepts for the Maybach luxury brand. The Exelero high-speed test car and the Ultimate Luxury SUV sedan come to mind. But the Project Maybach, designed in collaboration with late fashion designer Virgil Abloh, may be the wildest yet, being an electric off-road coupe. It's not just the fact it's a two-door off-road coupe. It's the fact that it's a nearly 20-foot-long two-door off-road coupe. And it has very traditional proportions and lines, with a gargantuan front end, and a somewhat less gargantuan rear end. It's squared-off, but in a more elegant, midcentury luxury car way than say, a Hummer. And of course, it has a huge chrome grille and highly embellished taillights, complete with Maybach logos. And yet, this old-school coupe sits high off the ground. It rolls on small, steel-style wheels with chunky tires. It even has skid plates, bolt-on fender flares, rock rails and a roll cage with a roof basket. It's all painted in a matte tan paint that makes it look like a desert-ready expedition vehicle. It's even arguably practical for expedition work. The somewhat spartan-looking interior has tan leather seats that recline fully flat for sleeping. Being an electric car with long areas unoccupied by people, plus that roof basket, it likely has loads of cargo space. On the hood are solar panels that might provide a bit of range, but would at least be handy for recouping some power for accessories. The interior seems to have additional storage bins and tools stowed in special compartments around the cabin. As for the actual performance and range, well, Mercedes has nothing specific. That's not entirely surprising, since this seems to be solely a design exercise. As such, don't expect to see a production model anytime soon. Then again, off-road luxury vehicles are certainly popular. Maybe Mercedes would consider it if there were enough seriously wealthy customers expressing interest. Related video:

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
