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 and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

The Dodge Challenger plays its trump card: all-wheel drive

Perennially stuck in third place behind the Ford Mustang and Chevy Camaro in sales and enthusiast comparisons, the Dodge Challenger is doing something unconventional for a muscle couple. It's adding all-wheel drive. It's a new feature for Detroit's pony cars – none of the three have ever had it – and it could be a game-changer. Called the Challenger GT, the Dodge launches this winter for a starting price of $34,490. The Challenger GT comes with the Pentastar 3.6-liter V6 rated at 305 horsepower and 268 pound-feet of torque. It teams with an eight-speed TorqueFlight automatic transmission and is estimated to get 18 miles per gallon in the city and 27 mpg on the highway. An FCA spokesperson said no manual transmission or V8 models will be offered on the all-wheel-drive Challenger. It will be on display in January at the Detroit auto show.

The coupe shares underpinnings with the four-door Charger, which offers an all-wheel drive variant and the cars have similar powertrain offerings (the AWD Charger is also V6 and automatic only). Naturally, the Challenger borrows the Charger's AWD system and during regular driving conditions, the front axle disengages and full torque goes to the back wheels, allowing the Challenger to function as a rear-wheel drive car. It automatically goes back to AWD when more traction is needed. Handling is also fortified with a vehicle dynamic control system. Conversely, the electronic stability control has three modes and can be switched off for drift-happy enthusiasts. The GT has features familiar to other Challenger and Dodge owners, including an 8.4-inch touchscreen radio, Performance Pages (accessible through the Super Trak Pack button), and paddle shifters. A Sport Mode changes shift points to improve acceleration. It all rolls on 19-inch wheels wrapped in all-season rubber. The exterior gets a hood bulge, LED head- and taillights, and a decklid spoiler. The Challenger GT also offers a $995-interior package different than RWD models, adding Nappa leather, Alcantara suede seats, a nine-speaker Alpine audio system, performance steering wheel, and more. All of that is just window dressing. It's all-wheel drive that could be a difference-maker for consumers. The Challenger won't likely be able to take down the Mustang, which will finish 2016 as the pony car sales king.
