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.

Watch the Dodge Charger SRT Hellcat verify its 204-mph top speed

The industry is producing some ridiculously fast four-doors these days, from the Porsche Panamera and Maserati Quattroporte to the Mercedes E63 AMG and BMW M5. But the fastest of them all doesn't cost six figures. It doesn't even come from Europe. It's made right here in North America, by a US automaker. And it starts at under $64k. We're talking about the Dodge Charger SRT Hellcat, the Pentastar muscle sedan with the 6.2-liter supercharged V8 and its 707 horsepower. Dodge claims it's the "quickest, fastest, most powerful [production] sedan ever," and they're not just blowing smoke... or smoking tires. During the final stages of development, engineers from Auburn Hills took a bone-stock, Hellcat-powered Charger out to a seven-mile oval for a top speed run and they filmed the occasion for posterity. The result? 206.9 miles per hour with the wind, 202.2 against it, for a two-way average top speed of 204.55 mph. Chew on that, imports.

Dodge Viper now available in matte finish

The prospect of buying a new Dodge Viper just got that much more enticing with the introduction of matte-finish paint direct from the factory. Available as part of the "1 of 1" customization program, the matte finishes aren't being offered in just a handful of colors like some other automakers do: customers will be able to specify a matte finish on any of the 8,000 colors that are already part of the program's palette. The matte finish option adds yet another step to the exhaustive hand-painting process that Dodge offers on the Viper - a painstaking endeavor that takes upwards of 145 man hours to complete. Specialists start by applying a base coat and a clear finish, followed by the paint and clear coat. The finished body panels are then smoothed with 1,000-grit paper and polished. A second sanding process is required for the matte finish before the application of a matte clear coat. Specify custom stripes (available in five colors or by custom order) and they're applied under the paint, not as decals on top. The availability of the matte finish in conjunction with the stripe options and new satin badging and fuel cap leads to over 50 million combinations. Needless to say, that means no two Vipers need ever leave the Conner Avenue assembly plant the same – though there will surely always be certain favorite combinations, especially on those units ordered from outside the customization program.
