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.

Stellantis axed the SRT engineer team, but performance isn't going away

Stellantis has broken up the Street & Racing Technology (SRT) engineering team that created over a dozen high-performance vehicles, including the Dodge Charger Hellcat, but the situation isn't as dire as it sounds. The newly-formed company assigned SRT's former engineers to different positions, where they'll continue to make hot rods. "All of the core elements of the SRT performance engineering team have been integrated into our company's global engineering organization," a spokeswoman told enthusiast website Mopar Insiders. She added that integrating SRT's personnel into other brands in the Stellantis portfolio will ensure that the lessons learned from decades of peddling speed will permeate other products. Previously, SRT operated with a high degree of independence. Don't get too excited. Her statement does not necessarily mean that Citroen will begin building cars powered by the Hellcat engine, though a C3 Chat D'enfer sounds absolutely epic. Technology transfer will likely be limited to fields like aerodynamics and thermal management, and the design department might learn a couple of neat new tricks. Dodge will still move forward with the development of its next SRT-branded cars; the decision to dissolve the SRT team will not affect future models, according to the spokeswoman. Whether they'll be powered by a V8 is up in the air, because company boss Tim Kuniskis warned that regulations are killing the eight-cylinder engine. Similarly, Jeep will continue designing high-performance models, like the Grand Cherokee Trackhawk. What changes is that the model will be developed and designed by a group of engineers and designers from Jeep, not from SRT. SRT is dead, but performance isn't going away. SRT's demise nonetheless marks the end of an era for Chrysler. The division traces its roots to 1989, when some of the company's brightest minds were brought together to develop the first-generation Dodge Viper. It merged with Team Prowler to form the Specialty Vehicle Engineering (SVE) group, which was renamed Performance Vehicle Operations (PVO) in 2002 and finally dubbed SRT in 2004. SRT has operated as the carmaker's in-house tuner since, its resume includes a diverse selection of cars ranging from the Neon SRT-4 to the 1500 TRX, and it was promoted to a standalone brand led by designer Ralph Gilles in 2011. Fiat-Chrysler Automobiles (FCA) axed the SRT brand in 2014 but kept the name and the development team. Related video:

Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.
