VQ Efficiency is a software solution that recalibrates and optimizes a Class 1-6 engine's rpm and idle speed for a specific region or route. Derive Systems reported average fleet fuel efficiency improvements of 6 to 10%. Emissions can be reduced by 2.9 cubic tons of CO2 per vehicle per year, according to the company. The software can be used alone or in conjunction with Derive's Safety and Telematics platforms, and is available for 62% of fleet vehicles, starting with model year 2013 vehicles. It’s typically a one-time, 30-minute install via the OBD-II port.
