Scope before using a number

Canadian NRCan rating configuration only. Trim, VIN fitment and service applicability are not independently established.

The source model label is preserved exactly, including wheel-size wording where present. AWD appears explicitly in that label. The NRCan class code C is a classification, not a country code; the market here is Canada.

The table retains the guide's transmission and fuel codes. No gear-count or component-design claim is inferred from their digits.

What this means for ownership

Which rating applies?

The IS 300 AWD entry specifies a 3.5 L six-cylinder and AS6. The 300 badge alone does not identify displacement. This row lists 12.2 city and 9.0 highway L/100 km.

Energy for an example 20,000 km year

Applying the guide's combined rating (55% city and 45% highway) gives 2,160 L: 20,000 km × 10.8 L ÷ 100 km. This is a calculation, not another source fact or a prediction. Multiply by your own premium gasoline price per litre for a simple energy-cost scenario; no current price, maintenance cost or depreciation is assumed.

Not established by this source

  • Service fluid grades and capacities
  • Tyre pressures and replacement fitment
  • Towing and payload limits
  • VIN/trim-specific applicability
  • Maintenance schedule

A missing value is not zero. These gaps do not count toward the existing service-fact publication standard.
