RAM Trucks is rolling out some new technology across the brand’s latest pickup models, including a new engine option that boasts best-in-class fuel economy. Autobytel caught up to Mike Cairns, the RAM Chief Engineer and Vehicle Line Executive for RAM Trucks, to get the details on RAM’s updated features and offerings for the 2014 model year. The biggest news is the EcoDiesel engine, a modern take on a diesel that challenges stereotypes and makes RAM the first brand to put a diesel powerplant in a light duty pickup truck, in response to increasing consumer demand. The RAM EcoDiesel is very quiet and refined, and it gets great fuel economy. The 3-liter 24-valve EcoDiesel features a variable geometry turbocharger, and it’s paired to an 8-speed transmission that takes maximum advantage of all the torque produced. This combination keeps the engine’s rpms low, helping to optimize fuel economy without compromising towing capacity. Other new RAM features include the 5-link-coil rear suspension system on the RAM 2500 series that’s a big improvement over the old leaf spring suspension, keeping the rear end of the truck planted on the road. Other RAM models get air suspension options, and an upgraded frame with an improved crossmember provides more structural rigidity.
