Semi trucks first.
The road ahead in focus.

Diesel efficiency, recalls, electric range, charging and autonomy—then the passenger vehicles and beautiful machines that keep the road interesting.

October truck & technology watch

The main focus / Class 8

The working machines.

Five diesel research picks. OEM fuel-improvement claims use different baselines; they are not a cross-brand MPG ranking.

MPG with its context attached

10.1 MPG / a real demonstration, not a model rating.

Seven Class 8 trucks averaged 10.1 MPG over NACFE’s 17-day 2017 Run on Less demonstration. This is a combined demonstration result; it does not assign that MPG to every truck or promise your fleet the same result.

Recall watch / five notices

Search all recalls by VIN ↗

    Selected campaigns, not a complete recall database. Applicability and completed repairs are VIN-specific.

    Electric + automated / Separate comparisons

    What is available. What is coming.

    Range and charging are OEM estimates with different test conditions. No comparable public heavy-truck safety rating was verified; no overall “best” score is invented. An automated transmission is not autonomous driving.

    Passenger vehicles & the design collection

    2025 model year / EPA combined MPG

    Five pickups to compare.
