IMPORTANT NOTE: This informational calculator is a comparison tool that allows you to compare the relative estimated fuel consumption and CO2 profile of an identically operated Toyota gas vehicle to a Toyota hybrid electric vehicle, using the Canadian federal government’s vehicle fuel consumption test methodology. The government methodology is a 5 cycle test carried out in a laboratory on a chassis dynamometer. The 5 cycles are: city test, highway test, cold temperature operation, air conditioner use, and higher speeds with more rapid acceleration and braking. The assumptions behind each test are more fully explained on the current Natural Resources Canada website: https://www.nrcan.gc.ca/energy/efficiency/transportation/21008. These tests attempt, within the confines of a theoretical laboratory test, to simulate 5 of the most common real world driving conditions. However, there are many other significant common real world variables that impact fuel consumption and no laboratory test is able to take into account all the variables that will affect individual fuel consumption. Your vehicle’s fuel consumption and CO2 profile will vary from the test ratings, depending on how, where and when you drive. The following factors will significantly affect the fuel consumption/CO2 profile of your vehicle: your driving style and behaviour, how you accelerate and brake, how fast you drive, overall age and condition of your vehicle, temperature, weather, traffic and road conditions, using drive systems like AWD or four wheel drive, using air conditioning and powered accessories installed on your vehicle. In addition, small variations in vehicle manufacturing will cause fuel consumption differences in the same make and model, and some vehicles do not attain optimal fuel consumption until they are “run in” for about 6,000 to 10,000 km.

As a result, many Canadian drivers WILL NOT achieve the fuel ratings or CO2 numbers stated in the government’s Fuel Consumption Guide or in our Electrified Toyota vs Toyota Gas Informational Calculator.
