The Humvee (which later spawned the civilian Hummer family of SUVs) was motivated by GM diesel power from the start, starting with the 6.2-liter naturally aspirated V-8 shared with the GM fullsize trucks of the time, later graduating to a 6.5-liter, and then a 6.5-liter turbodiesel.

Well, now it may be Ford's turn to power the next-generation Joint Light Tactical Vehicle (JLTV). BAE Systems, along with partners Northrop Grumman and Meritor Defense, have submitted a proposal for the Engineering and Manufacturing Development (EMD) phase of the JLTV program.

The designated powerplant is the new 6.7-liter Powerstroke (also known as the "Scorpion"among some diesel enthusiasts) to power the new family of vehicles.

But BAE is not alone in its bid to build the next-generation tactical vehicle. Defense contractors Navistar and Lockheed Martin have also submitted proposals for the JLTV. Navistar's bid, based on the company's Saratoga platform, is powered by the company's MaxxForce 6.0D V-8 diesel engine, which, ironically enough, formerly powered Ford's Super Duty line.

Lockheed Martin also submitted its proposal. Interestingly, BAE was again mentioned as a partner in this project as well. Stephanie Serkhoshian, Land & Armaments BAE spokeswoman, explained this puzzling coincidence is due to BAE's 2007 acquisition of Armor Holdings, the successor division of which is part of the Lockheed Martin team. Although part of the same parent company, the groups are autonomous and working on separate proposals.

The government will award up to three EMD contracts in June 2012. The EMD phase is no trivial matter, as it entails the development and delivery of 22 prototype vehicles and other equipment for testing. The JLTV is designed to effectively replace the long-running Humvee. There was a plan to modernize and upgrade the existing fleet of Humvees, but that program has been canceled, and the JLTV is in line to take its place.
