Cummins' Upcoming X12 Does A Lot With Less

摘要

Light weight is the point of Cummins' X12 truck diesel, due for use in North America in six to nine months. The bottom line is the X12's stated dry weight (without fluids) of 2,050 pounds, or 150 to 400 pounds less than comparable engines now on the market. Yet it offers the healthy horsepower and torque ratings of a larger diesel, and it performs like one. That's what I found on a drive of a Freightliner Casca-dia tractor fitted with an X12, during Conexpo in Las Vegas earlier this year. The demo rig included a van carrying a moderate load and freshly decaled with graphics promoting this engine. Mario Sanchez, director of on-highway marketing communications, had it waiting at Cummins' new distributorship in North Las Vegas, just off Interstate 15.
