Fuel economy labels for dedicated natural gas vehicles must meet the specifications described in § 600.302, with the following modifications:
- (a)Include the following statement instead of the statement specified in § 600.302-12(b)(4): “Actual results will vary for many reasons, including driving conditions and how you drive and maintain your vehicle. The average new vehicle gets a MPG and costs $b to fuel over 5 years. Cost estimates are based on c miles per year at $d per gasoline gallon equivalent. Vehicle emissions are a significant cause of global warming and smog.” For a, b, c, and d, insert the appropriate values established by EPA.
- (b)Include the following elements instead of the information identified in § 600.302-12(c)(1):
- (1)The heading “Fuel Economy” near the top left corner of the field.
- (2)The combined fuel economy value as determined in § 600.311 below the heading. Include the expression “combined city/hwy” below this number.
- (3)The logo specified in § 600.302-12(b)(3)(ii) to the left of the combined fuel economy value.
- (4)The units identifier and specific fuel economy ratings to the right of the combined fuel economy value as follows:
- (i)Include the term “MPGe” in the upper portion of the designated space.
- (ii)Include the city fuel economy value determined in § 600.311 in the lower left portion of the designated space. Include the expression “city” below this number.
- (iii)Include the highway fuel economy value determined in § 600.311 in the lower right portion of the designated space. Include the expression “highway” below this number.
- (5)The fuel consumption rate determined in § 600.311, to the right of the fuel economy information. Include the expression “equivalent gallons per 100 miles” below the numerical value.
- (6)The sub-heading “Driving Range” below the combined fuel economy value. Below this sub-heading, insert a horizontal range bar nominally 80 mm long to show how far the vehicle can drive when fully fueled. Include a vehicle logo at the right end of the range bar. Include the following left-justified expression inside the range bar: “When fully fueled, vehicle can travel about * * *””. Below the right end of the range bar, include the expression “x miles”; complete the expression by identifying the appropriate value for total driving range from § 600.311. Include numbers below the bar showing the scale, with numbers starting at 0 and increasing in equal increments. Use good engineering judgment to divide the range bar into four, five, or six increments.
