How are light-duty cars and trucks expected to meet future EPA fuel economy standards? What level of electrification would be required? Would hybrids play a role? How does one go about calculating it? Here’s a case study attempting to address some of these questions.
On April 12th 2023, the U.S. EPA published a proposal to further reduce greenhouse gas and criteria pollutant emissions from light- and medium-duty vehicles beyond model year 2027. Here is a summary of this “multi-pollutant” regulatory proposal.

Europe has proposed an ambitious revision to its heavy-duty vehicle CO2 emission standards. Here’s a summary of some of the revised and new elements
An updated summary of available hydrogen fuel cell electric trucks and buses, their announced range and hydrogen capacity.
A summary of CARB’s latest Advanced Clean Fleets proposal for heavy-duty truck electrification as discussed in the February 2023 Workshop.
The US EPA has finalized its standards for heavy duty engines starting model years 2027 and beyond. Here is a summary of the standards and a high-level comparison with California’s low NOx rule published earlier.
Yes, OEMs continued developments of new gasoline engines in 2022. Here’s a short write-up of key technologies added covering a range of 1.5L to 3L engines.
We show that to convert 25% of the long-haul truck fleet in the US to hydrogen fuel cell will require doubling of the total H2 demand and doubling of the renewable electricity generation in the US today.
Here’s an attempt at deconvoluting the cost of ownership of H2-ICE and a comparison with diesel and fuel cell vehicles.
