For only the second time in our history we have we focused our resources on a technology — or in this case a family of technologies — that are not commercially available.

We released our Confidence Report on Variable Engine-Driven Accessories because manufacturers are working hard on a making improvements in this area and we wanted to make sure you had some basic information. All of the items we studied put a load on the engine but do not help propel the vehicle down the road. Basically they rob the engine of power without helping move the vehicle.
