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.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

BMW Recalls 1.6 Million 3 Series Cars For Air Bag Problem

DETROIT (AP) - BMW is expanding a recall of its most popular models to fix an air bag problem that is hitting much of the global auto industry. The German automaker says it will recall 1.6 million 3 Series cars from model years 2000 to 2006 across the world, including 574,000 in the U.S. The company said Wednesday that it's a precaution because other automakers using similar systems have reported problems. Air bag inflators in systems made by Takata Corp. can rupture. If that happens, the bags might not work properly, and shards could fly out and cause injury or death. The problem is responsible for millions of recalled vehicles during the past few years made by manufacturers such as Chrysler, Ford, Honda, Mazda, Nissan and Toyota. Here's a look at the long history associated with this problem, that affects millions of cars. BMW said it has no reports of problems in its vehicles. Dealers will replace the passenger-side front air bags. The new recall excludes 42,000 BMWs recalled in May 2013 for the same problem. The company says it is recalling all vehicles equipped with potentially faulty air bag systems regardless of where they were sold. In June, the U.S. National Highway Traffic Safety Administration began investigating air bags made by Takata, a Tokyo-based supplier of seat belts, air bags, steering wheels and other auto parts. The agency said it received six reports of air bags rupturing in Florida and Puerto Rico. Three people were injured in those cases. It had estimated 1.1 million vehicles in the U.S. could be affected, but the total is likely to climb. The government says it wanted to act quickly in warm states while it continues to investigate the issue. "Based on the limited data available at this time, NHTSA supports efforts by automakers to address the immediate risk in areas that have consistently hot, humid conditions over extended periods of time," the agency said in a statement. Takata said in a statement Tuesday that it is supporting the NHTSA investigation and its customers with technical analysis and replacement parts. "Our objective is to do all that is possible to ensure the safety and well-being of the public," the statement said. Related Gallery AOL Autos Test Drive: 2014 BMW 428i
