Road Transport Expo 2025: Cummins updates T&BB on Euro 7 and alternatives to diesel
By Bradley Osborne – 12th August 2025
Although it is today a manufacturer of various electric products – including e-powertrains, battery packs, and electrolysers – American engine manufacturer Cummins Inc is also concerned about regulation that focuses only on tailpipe emissions rather than a holistic well-to-wheels approach. In a previous conversation with Truck & Bus Builder, Bill Lamb, director of Cummins’ engine business platform strategy, noted that, with the current rate of battery-electric truck adoption, commercial vehicle manufacturers will find it extremely challenging to meet future CO2 emissions reduction targets without the help of two alternatives to pure electric: hybrid and biofuels. We met again at the recent Road Transport Expo, held between 24-26 June at NAEC Stoneleigh, to discuss not only alternatives to electric but also Cummins’ progress towards Euro 7.
