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.

Historic race cars highlight the RM Sotheby's 2023 Le Mans sale

Auction house RM Sotheby's is celebrating 100 years of the 24 Hours of Le Mans by organizing a big sale on the day before the race. The cars scheduled to cross the auction block have all spent time on the track, and the catalog shows how racers have evolved since the 1930s. Browsing through RM's auction catalog is like taking a five-minute course in the history of racing. The oldest car is a 1932 Aston Martin Le Mans 'LM8' that's had a remarkable life. It was developed and built for competition and entered in the 1932 24 Hours of Le Mans by the Aston Martin factory team, where it finished seventh. It was ultimately sold to a private owner but it survived, which shouldn't be taken for granted: teams often destroyed obsolete race cars, and the list of special vehicles that didn't survive World War II is longer than you'd think. Paul Sykes bought the car in 1955 and used it as his daily driver. Imagine walking out of a shop in a British village in the 1960s and finding a 1932 race car parked next to your Mini. Sykes ultimately bought another daily driver, but he kept the Aston Martin for a total of 55 years. The second-oldest car is a 1936 Delahaye 135 S with a body by coach builder Pourtout. RM notes that this is one of the most significant pre-war competition Delahaye models and adds that it finished second in the 1938 edition of the 24 Hours of Le Mans. It continued racing until 1956 and then spent several decades hidden in storage. It was fully restored in 2005, and it's now eligible to compete in historic races such as the Mille Miglia and the Le Mans Classic. Restoring it was easier said than done: the car was rebodied twice before being tucked away. None of the cars crossing the block were built in the 1940s, so we skip ahead to the 1950s with a 1954 OSCA MT4 by Morelli. It's one of 72 built, according to RM, and only 19 of those were fitted with the twin-cam, 1.5-liter 2AD engine. It raced at Le Mans in 1954 but ended up disqualified following an accident. Another highlight from the 1950s is a 1958 Lister-Jaguar 'Knobbly' finished in yellow and green. We said that all of the cars crossing the block have spent time on the track, but that doesn't mean they were built to race. The 1963 Ferrari 250 GTE 2+2 Series III is a street-legal model, yet it's included in the auction because it was used as a safety car during the 1963 edition of the race.

Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.
