H2 ICE truck cost of ownership vs diesel and fuel cell vehicles
Here’s an attempt at deconvoluting the cost of ownership of H2-ICE and a comparison with diesel and fuel cell vehicles.
Electric and hybrid penetration by 2030 based on new CO2 targets
The EU has published the “Fit for 55” proposal which will require 55% reduction in tailpipe CO2 by the end of the decade. The Biden administration will also revise the SAFE standards and has announced a 50% electrification target by 2030 (including plug-in hybrids). Here is a look at the implications for powertrain scenarios based on the CO2 targets alone.
SuperTruck II Update : Notes from the 2021 DOE Annual Merit Review
As we enter into the final lap of the SuperTruck 2 program, all teams are confident of meeting the 55% BTE and doubling-of-freight-efficiency targets. Here are the technical solutions being pursued.

CARB proposes to amend MY 2024 low NOx standard
Given the lack of MY 2024 compliant new engine introductions, California has proposed an amendment to its low NOx omnibus, providing more flexibility for legacy engines.
CARB deal with OEM on low NOx, electrification – and H2 ICE ?
California and Truck & Engine Manufacturers have reached a deal on low NOx and electrification targets in the state. This paves the way for more regulatory certainty but the challenges ahead are not diminished.
Technology Deepdive : Opposed piston engines
Opposed piston engines are being developed as a tool to reduce CO2 and NOx emissions from heavy-duty trucks. Here’s a deeper look into this technology and recent test results.
U.S. EPA Phase 3 Greenhouse Gas Proposal for Heavy-Duty Vehicles
A downloadable summary of the U.S. EPA announced the Phase 3 GHG proposal for heavy-duty vehicles. From 2027 to 2032, 45% reduction in CO2 emissions for light vocational vehicles and 25% for Class 8 sleeper cabs. Over half of light vocational and a quarter of sleeper cabs expected to be ZEVs by 2032.
What’s in a tire – you may be surprised
Tire manufacturers are developing the next generation tires for light- and heavy-duty vehicles to address the new performance and sustainability needs of electrified fleets.
Revised CO2 standards in Europe for heavy-duty vehicles
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
