  is the benefit obtained from A to B testing, expressed in grams of CO₂ per short ton-mile, determined in accordance with,

  • (a) in the case of a post-transmission hybrid system, section 555 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, taking into account section 525 of Title 40, chapter I, subchapter U, part 1036, subpart F, of the CFR, and

  B

  is the payload for the class of vocational vehicles, incomplete vocational vehicles, tractors or incomplete tractors, as the case may be, which is

  • (a) 2.85 short tons for vocational vehicles that are light heavy-duty vehicles and incomplete vocational vehicles that are to become light heavy-duty vehicles,

  • (b) 5.6 short tons for vocational vehicles that are medium heavy-duty vehicles and incomplete vocational vehicles that are to become medium heavy-duty vehicles,

  • (c) 7.5 short tons for vocational vehicles that are heavy heavy-duty vehicles and incomplete vocational vehicles that are to become heavy heavy-duty vehicles,

  • (d) 12.5 short tons for Class 7 tractors and incomplete tractors, and

  • (e) 19 short tons for Class 8 tractors and incomplete tractors;

  C

  is the number of vehicles in the fleet or subfleet, as the case may be; and

  D

  is the useful life of the vehicles of the fleet or subfleet, as the case may be, expressed in miles.

• Marginal note:Credit multiplier

  (3) The additional credits calculated in subsection (2) may be multiplied by 1.5 if the company does not use the early action credit multiplier referred to in subsection 47(6) for the same vehicles.
