Watch new 2014 Ram ProMaster full-size van debut at the Chicago Auto Show > The Fast Lane Car

The new 2014 Ram ProMaster full-size van makes its debut at the Chicago Auto Show this week with best-in-class fuel economy, cargo capacity and payload. This van is targeted at commercial customers who want a vehicle that's tough, functional and customizable to their exact business needs. Based on the Fiat Ducato, the 2014 Ram ProMaster marks the North American debut of the 174hp 3.0-liter I-4 EcoDiesel. This engine has been refined to decrease cost of ownership including an oil level sensor that can help keep it going for 18,500 miles between oil changes. It's also available with a 280hp 3.6-liter Pentastar V-6 which has ranked in Ward's 10 Best Engines for the last three years. Cost of ownership was again a priority with oil change intervals running up to 10,000 miles and an alert that sounds when its oil servicing system determines it's time to change.
