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.

Junkyard Gem: 1991 Dodge Stealth R/T

Chrysler's relationship with Mitsubishi goes back to the early 1970s, when the first Mitsubishi Colt Galants arrived from Japan with Dodge Colt badging. Plenty of Mitsubishi-built Arrows and Ram 50s and Challengers followed, and the joint Chrysler-Mitsubishi plant in Illinois began building cars in 1988. By the 1990s, you could find Mitsubishi DNA throughout the American Chrysler family, and the Mitsubishi GTO was brought over to become the Dodge Stealth starting in 1991. Here's one of those first-year Stealths, now residing in a Colorado self-service boneyard. Four grades of Stealth were available here in 1991, with the R/T Turbo AWD at the very pinnacle. This car, a regular R/T, is one step down from that model but still a pretty quick machine for its time. MSRP was $25,155, or about $55,370 in 2022 dollars. The R/T got this naturally-aspirated DOHC 6G72 engine, displacing 3.0 liters and making 222 horsepower. If you got the turbocharged version in the R/T Turbo AWD (or the Mitsubishi 3000GT VR-4), power went up to 300 horses. The 3000GT (as the GTO was known here) was mechanically identical to this car but had slightly different styling. The GTO/3000GT/Stealth replaced the Mitsubishi Starion and its Chrysler/Dodge Conquest siblings, which were sold here from the 1983 through 1989 model years. The Starion was a rear-wheel-drive machine that competed for sales against the Toyota Supra and Nissan Z, while the Mitsubishi GTO was available with either front- or all-wheel-drive. As illustrated by this photo of the rear suspension, this car is a front-wheel-drive version. Americans loved automatic transmissions 30 years ago, nearly as much as we love them today, but this car has a proper five-on-the-floor manual. If you wanted the optional four-speed automatic, it cost 813 bucks ($1,790 today). The Stealth R/T AWD had a mandatory five-speed manual transmission. This car has been hit hard by junkyard shoppers and the ravages of time, but it was fairly luxurious when new. Air conditioning was standard equipment on the R/T, though not on the lesser Stealths. This car came close to 150,000 total miles, but fell a bit short of that milestone. The final year for the Dodge Stealth was 1996, though the Mitsubishi 3000GT remained available here through 1999. The Mitsubishi GTO held on through 2000 in its homeland. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Outhandles the Lotus Esprit!

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric
