I would say hybrids, and clearly electric and hydrogen fuel-cell* powered buses qualify by definition being zero-emission. I'm not sure the so-called "smart hybrids" reduce emissions enough to qualify but I could be wrong. By the Zemo definition CNG (Compressed Natural Gas) power as used by some Reading Buses and Nottingham City Transport vehicles would also qualify as ULE, but no TfL contractor operates CNG-powered buses.

Is this really correct? The vehicles listed do not need to pay the ULEZ charge, or have I found outdated info?

Thanks that makes sense. Hybrids have helped achieve today's EVs. It is a stepping stone. Initially I thought 30% better for the environment was not much but it is huge. I would say the series hybrids are more green and environment friendly compared to the parellel. Happy to be corrected though.

I would say the series hybrids are more green and environment friendly compared to the parellel. Happy to be corrected though. There is not a lot in it really. In a series, the bus is powered by an electric motor. The electric motor is powered by batteries, the diesel engine tops up the batteries and provides more power to the electric engine if the batteries are insufficient. In a parallel, the bus is powered by both electric and diesel, with the diesel kicking in when the batteries are insufficient. Personally would have thought parallel is more efficient as series coverts diesel energy into electric energy so energy is lost in conversion, where as the in a parallel, the raw diesel energy is used to power the vehicle.

Is TfL operating as normal on 19th September 2022?

Some curtailing routes appear to have had their destination announcement/displays changed on passenger info screens. The 87 for example shows as "Millbank, Houses of Parliament" with the 159 as "County Hall, York Road". Are these curtailment name changes done for the duration of the Queen related Central London closures or permanent for general curtailments?

My understanding is that there's a longer established, and wider ranging (more or less all of London) Low Emission Zone for larger vehicles.
The page you link to goes on to say "These vehicles will need to pay the London-wide LEZ charge if they do not meet the LEZ emissions standard."

LEZ standards for buses are Euro VI.

LEZ standards for buses are Euro VI. That is actually for TfL contracted bus services, not really anything to do with the LEZ. But other larger vehicles? **EDIT** was hard work trying to find the current LEZ limits ... but seems the limit increases to Euro6 in March 2021 ... does that not technically make it a ULEZ?

Why does the SMART Hybrid MMCs sound totally different to conventional Diesel MMCs?

Why does the SMART Hybrid MMCs sound totally different to conventional Diesel MMCs? They sound different but not totally different - you can still hear the familiar characteristics of a Euro VI Voith box on both examples with the Smart hybrids having an extra, sort of electrical type sound alongside

I wonder if the full EVs have different sounds depending on type. E g the BYD vs Optare?
