If these fuel consumption ratings are accurate, one can expect to have an additional excise fuel tax added to the car price before tax. On the 12/19 mpg (19.6/12.4 l/100k) EPA rating the tax is $4,000 and on the 12/21 mpg (19.6/11.2 l/100k) EPA rating the tax is $3,000. (refer to
Current Rates of Excise Taxes - Canada.ca ). The Select Luxury Item Tax and applicable Sales Tax is on top of that!
