Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg

You never quite know what Wayne Gerdes has up his sleeve. The man who coined the term hypermiling is always looking for adventurous ways to prove that anyone – even you... yes, you – can eke out more miles per gallon just by changing the way you drive. Saying that is easy. Proving it by going on outlandish cross-country drives is hard. But for Gerdes and his team of fuel economy fiends over at CleanMPG, hard is half the fun. Our latest adventure appeared, at first glance, to be nearly impossible. Which is why we always answer the phone when Gerdes calls. He likes to take journalists along on his drives, not only to try teach us how to hypermile but also to prove that we can be taught. The first time I 'helped' him and his team was when we got over 30 miles per gallon in a 2011 Ford F-150 XLT with the EcoBoost 3.5-liter V6. The EPA rated that truck with at just 16 mpg in the city and 22 on the highway. So, we'll count that trip as a success. Next up was a cross-country drive last fall in a trio of Audi TDI vehicles to prove that you don't need to drive extra slow to beat the EPA numbers. In fact, we made it from Los Angeles to New York City in just over 46 hours, cramped but not cranky. We had once again proven that how you drive is hugely important to your fuel usage. Our latest adventure appeared, at first glance, to be nearly impossible. The EPA says that the Ram 1500 EcoDiesel we would be driving gets just 22 combined mpg (19 city and 27 highway). Gerdes' idea was to drive it as far north from Houston, TX towards Detroit, MI as we could go on one tank. The day before we left, our itinerary got an extra stop. Instead of taking one of the official Shell Eco-marathon prototype vehicles to Detroit, it was decided to bring the winning diesel-powered prototype from the just-finished event to The Henry Ford Museum, where it had been arranged the car would be displayed. The winning car was built by a small team (just four students) from Sullivan High School in Sullivan, IN, who managed to beat a number of college teams with a score of 1,899.32 mpg. That target would be a bit out of reach for the Ram, but could we get 1,000 miles from the tank? Since the truck has a 26 gallon tank (officially, anyway), that would mean the EPA says we could only go 702 miles, assuming all highway driving. Could we make up 300 miles with careful driving? That spells both challenge and fun.

FCA UConnect fiasco could set over-the-air updates back years

Since cars have become more software dependent, most major automakers have been inching toward enabling over-the-air updates to keep vehicle electronics, ranging from infotainment systems to safety features, current. But there are only two car companies — Fiat Chrysler and Ford —± currently doing OTA updates, and on a limited basis. GM CEO Mary Barra announced last summer that the automaker will launch a new EV architecture and infotainment system capable of over-the-air updates "before 2020." The one exception, per usual, is Tesla. Since the release of the Model S almost six years ago, the maverick EV automaker has made routine OTA software updates a core part of its vehicle platforms and value proposition, and has sent out updates for everything from adjusting ride height to enabling Autopilot, largely without incident. When I've asked automakers why they can't do the same thing, I've heard reasons ranging from running afoul of their dealers (and archiac regulation) to security concerns. Automakers like Ford and General Motors say they want to act like tech companies, which routinely send out OTA updates for a wide range of devices, but overall the car industry still moves at a very cautious snail's pace. And when automakers do try to move faster and take more risks — unlike with a smartphone update, which people bitch about but live with — the consequences can be significant when things go wrong. That's the case with Fiat Chrysler America and its recent public-relations nightmare when an OTA update went awry. The update went out at the end of last week for the Uconnect system in late-model vehicles, and it made head units go into a near continuous reboot, which caused owners to not only lose access to entertainment features, but also critical functions like emergency assistance. Almost immediately, owners took to Twitter to express outrage, and FCA was caught flatfooted. A tweet went out on Monday on the UconnectCares Twitter account that read, "Certain 2017 & 2018 Uconnect systems may experience a reboot every 45-60 seconds. Our Engineering teams are investigating the cause and working towards a resolution.

Dodge recalls 121,603 examples of Dart for loss of brake assist

Dodge will recall 121,603 worldwide examples of the 2013-2014 Dart with the 2.0- and 2.4-liter engines because of possible loss of power brake assistance. The company reports two minor injuries and seven accidents potentially related to this problem. The affected models have build dates before Jan. 24, 2014. There are 105,458 of these vehicles in the US; 11,996 in Canada; 3,705 in Mexico; and 444 outside of NAFTA. This campaign doesn't affect Darts with the 1.4-liter engine. These vehicles' brake-booster vacuum tube routing can potentially allow oil to access and eventually to degrade the brake booster diaphragm. If this happens, then the vehicles could lose braking assist. The brakes themselves would continue to work, but the driver would experience longer stopping distances. A pop or similar sound of a vacuum leak sometimes precedes the problem, according to the automaker. Dealers will inspect the components and replace the vacuum tube. If technicians find oil in the tube, they'll also swap out the vacuum pump, brake booster, and master cylinder. Affected owners will receive notice from the company within the next 60 days. Statement: Vacuum-tube Assembly December 3, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 105,458 compact sedans in the U.S. to inspect and replace vacuum-tube assemblies and certain other components, as required. Some of the affected vehicles may be subject to oil migration that could affect their brake systems' power-assist feature. Foundation brake function is unaffected. However, if this condition occurs, the driver may notice hard pedal-feel on brake application, and longer distances may be required to stop the vehicle in emergency situations. An FCA US investigation identified certain model-year 2013-14 vehicles equipped with 2.0-liter and 2.4-liter engines, may have brake-booster vacuum-tube routing that inadvertently allows oil to reach the brake booster diaphragm, if ever the vacuum-pump check valve fails. Oil may degrade the diaphragm and lead to a loss of brake-assist – a feature that helps reduce stopping distances. FCA US is aware of two minor injuries and seven accidents that are or may be related to this condition. The recall is limited to model-year 2013-14 Dodge Dart sedans produced before Jan. 24, 2014. It also affects an estimated 11,996 cars in Canada; 3,705 in Mexico and 444 outside the NAFTA region. Vehicles equipped with 1.4-liter engines are excluded.
