The Detroit Auto Show is going to be quite an event for pickup fans thanks to introductions of the new Toyota Tacoma and at least the rumor about the future F-150 Raptor. In addition to them, Nissan will finally unveil its next-gen Titan after months of teasing and spied glimpses.

Toyota might be content to eke out an existence in the fullsize pickup market with its lightly refreshed Tundra, but Nissan looks like it'll be a bit more aggressive with its next-generation Titan. The next Titan will make use of a 5.0-liter, turbodiesel V8 from Cummins, the Japanese company announced at the start of its Nissan 360 industry showcase.

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.

Ram is going for broke with its 2012 truck range, increasing power in both the 5.7-liter Hemi and 6.7 Cummins diesel. The gas V8 gets a bump to 383 horsepower and 400 pound-feet of torque. The 6.7-liter Cummins diesel inline six now pushes 350 horses backed by 800 lb.-ft. of torque.

Chrysler has announced the recall of 186,099 model year 2007-09 Dodge Ram 2500 and 3500 Heavy Duty pickup trucks equipped with the 6.7-liter Cummins diesel engine. The voluntary recall has been issued due to an engine defect that could cause the check engine light to come on. In some cases the engine can produce heavy soot that could damage the turbocharger, exhaust gas recirculation valve and diesel particulate filter, which are some very expensive components to repair in a modern, high-tech oi

During last summer's bankruptcy proceedings, New Chrysler chose not to pick up the contract it had previously entered with Cummins to procure light-duty diesel engines for its line of Ram pickup trucks. At a rumored 5.0 liters, this powerplant would be somewhat less powerful but likely less expensive and more fuel efficient than Dodge's larger 6.7-liter inline six diesel, also supplied by Cummins.

Cummins Inc. has lodged a settlement in the U.S. District Court for D.C. agreeing to pay a $2.1 million penalty for violating the Clean Air Act. What did Cummins do? Well, it "shipped more than 570,000 heavy duty diesel engines to vehicle equipment manufacturers nationwide without pollution control equipment included" between 1998 and 2006. Even with that many engines sold, Cummins has agreed to recall only 405 of them because that is all that "were found to have reached the ultimate consumers w

For years, diesel-powered Dodge Ram pickup trucks have featured powerful inline six-cylinder engines from Cummins. By all accounts, the partnership has been successful and the Cummins diesel engines are highly regarded in the industry. Therefore, it wasn't exactly shocking to hear that the planned light duty diesel engine for the Ram 1500 pickup would be sourced from Cummins.

Just about a month ago, Chrysler's Frank Klegon confirmed that the light duty diesel engine for the Dodge Ram was moving towards production in 2010. Now, some reports are suggesting that the 5.0L V8 from Cummins may be delayed until 2011. With the current state of affairs in the auto industry and the recent announcement that Fiat and Chrysler were entering a strategic global alliance, we'd imagine that pretty much all of the Pentastar brand's plans have been shaken up a bit, including this one.
