How weight affects fuel consumption
(NC)—The heavier the vehicle the more energy it needs to get moving. Heavier vehicles have greater inertia and greater rolling resistance, both of which contribute to increased fuel consumption. Reducing weight is a powerful way to raise a vehicle's efficiency. This applies both to the weight of vehicle and the weight of the load being carried. Lighter really is better when it comes to saving fuel and reducing greenhouse gas emissions. Source: Natural Resources Canada. www.vehicles.nrcan.gc.ca.
