LAS VEGAS — Navistar Inc.’s S13 integrated powertrain for its on-highway trucks is the manufacturer’s last new internal combustion engine. It is the strongest signal yet that legacy truck makers are embracing electric trucks with zero tailpipe emissions.

Combined with aerodynamic styling, the new powertrain that goes into production in July 2023 offers up to 15% better fuel efficiency than the current A26 engine and Eaton Cummins Endurant transmission in Navistar’s flagship on-highway...

Despite what the pump reads, fuels savings still a possibility

The price of diesel currently stands around $5 per gallon, up approximately $1.74 since September. Bob Bortner, mid-Atlantic territory manager for commercial tire and fleet solutions leader IMI, said diesel costs have risen approximately $1.74 since September.

He believes it’s doubtful the pumps will show mercy anytime soon, but that doesn’t mean fuel savings aren’t possible. Facing nearly vertical price hikes, fleets must get creative.

“The most important factor in fuel [efficiency] for a...

Port logjams increase biofouling, harming fuel efficiency, marine life — study

Port congestion and increased idle times make biofouling worse, according to a recent I-Tech study.

Biofouling — the accumulation of barnacles, plants and algae on ship hulls — is only getting worse as waters warm and as port congestion increases idle time, according to a recent I-Tech study.

As it builds up, the biological material adds drag and reduces fuel efficiency, costing shippers money and releasing greenhouse gases unnecessarily. The study found that the risk of biofouling accumulation increases significantly when a vessel idles or is in warmer water.

“Fouling takes place significantly...
