4. Nissan Frontier Diesel Runner
Everyone is buzzing about diesel these days. Nissan made headlines when it announced plans to put a 5.0-liter Cummins mill in its new Titan and the company shook things up again in Chicago by slotting a 2.8-liter Cummins four-cylinder into its smaller truck. The engine makes approximately 200 hp and over 350 lb-ft of torque. Nissan says plans to produce the truck will be based on customer feedback at this show and those subsequent events.
