Cummins builds 2-millionth diesel for Ram

Ahead of a new Ram Heavy Duty that will debut sometime next year (check out the spy shots below), Chrysler and Cummins are celebrating a milestone in a 24-year partnership that has supplied the Ram pickup with diesel engines.
In its early years, the Cummins straight-six turbo diesel was rated at just 160 horsepower and 400 pound-feet of torque, and its clattering 12 valves could be heard from a mile away. Its most recent configuration still uses a straight-six layout, but displacement grew to 6.7 liters in 2007 allowing the engine to now produce up to 385 hp and a whopping 850 lb-ft of torque. While a rumored smaller Cummins engine for use in the light-duty Ram 1500 never materialized, the work-ready 6.7-liter Cummins turbo diesel accounts for 80 percent of all Ram HD sales.
Chrysler has not yet announced when and where this two-millionth engine will be on display, but you can read more about the engine and the partnership in the press release below.

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.

2018 Ram 3500 takes the truck torque crown

In the neverending war for bragging rights between pickup manufacturers, Ram just picked up a big one. The new 3500 heavy duty has an updated 6.7-liter Cummins straight-six diesel that produces 930 pound-feet of torque. Not only is that a gain of 30 pound-feet of torque over the outgoing model, but it's more than the heavy-duty trucks from Ford and GM. Specifically it makes five more pound-feet than the 925 pound-feet of torque in the most potent Ford Super Duty, and 20 more than the Silverado and Sierra heavy-duty trucks that make a maximum of 910 pound-feet. Ram didn't provide horsepower specs for the new Cummins engine, though. The outgoing engine made 385 horsepower. If Ram and Cummins were able to get such a large boost in torque, odds are that horsepower has also increased. There's also a good chance that even with more power, the updated Cummins may not exceed the horsepower ratings of the Ford and GM trucks. The Ford is currently second place in power with 440 horsepower, and the GM trucks have the most with 445. Final specs on horsepower, as well as pricing will probably appear soon, since the trucks will be arriving at dealerships at the end of August. Related Video: RAM Truck
