Currently, the CAFE penalty is US$55 per vehicle for every 1 mpg under the standard. For the year 2006 Mercedes-Benz drew a $30.3 million penalty for violating fuel economy standards by 2.2 MPG, or $122 per vehicle. According to the government "fueleconomy.gov" website violating CAFE by 2.42 MPG means consuming extra () of mostly imported fuel in 10 years which is worth $3,490 (Based on 45% highway, 55% city driving, 15,000 annual miles and a fuel price of $2.95 per gallon) that is 13.4% more and also it means emitting extra 14 Tons of CO2 in 10 years that is 12.7% more. These numbers are based on comparison of 2010 Mercedes ML 350 4MATIC with CAFE Unadjusted Average Fuel Economy of 21.64 MPG (this model meets 2006 CAFE requirements of 21.6 MPG) and 2010 Mercedes ML 550 4MATIC with CAFE Unadjusted Average Fuel Economy of 19.22 MPG. So consuming extra $3,490 worth of mostly imported fuel and emitting extra 14 Tons of CO2 draws a penalty of only $122 for a single luxury car buyer. $122 is only 0.3% of the price of $40,000 car (average 2010 price of a luxury car). Several experts stated that this is not enough of a monetary incentive to comply with CAFE.
