Auto makers push for higher-quality fuel

In January, 2008, the federal government first indicated plans to revise fuel consumption regulations for new vehicles. At the time, the U.S. government was going down the same road. Our emission, fuel economy and safety regulations have been in lockstep with the Americans because the same vehicles are either built in or sold in both countries, so the tighter standards made sense.

The very ambitious U.S. targets are 35 miles per gallon – or 6.7 litres/100 km – for the average fuel economy of vehicles sold in 2020 with new standards beginning in the 2011 model year.
