Engine Downspeeding Made Easy

Dana recognizes the challenges that face fleet owners across the country. A shortage of drivers and fleet technicians is raising overhead as fleet owners need to raise drivers’ pay and offer ever-greater incentives. Meanwhile, U.S. fuel economy and greenhouse gas standards are becoming increasingly stringent, requiring fleet owners to find ways to improve fuel efficiency while still keeping an eye on the bottom line. The Dana Aftermarket Group can’t do much about the first set of challenges, but by offering service parts that facilitate engine downspeeding, we can provide your customers with an excellent solution for the latter.

Engine downspeeding helps decrease fuel consumption, reduce engine friction, diminish relative heat transfer, and increase thermodynamic efficiency. It involves ensuring every element of your powertrain is working together to deliver power with maximum efficiency. To achieve this, your customers need to specify the right parts for their fleet. The Dana Aftermarket Group can help, with a full-system solution that makes engine downspeeding easy.

Increase your overall vehicle efficiency by up to 2% and save more than 2,700 gallons of fuel over five years.
