Buses and coaches bursting into flames - why are they apparently so combustible? (merged topic)

[whole diary]

Euro 6 bus again. The exhaust systems run ridiculously hot to burn off and reduce emissions. They also have tiny engines compared to buses in the past which works extremely hard.
To my knowledge there has been no electric bus fires caused by mechanical. The only one I know of was arson by a passenger upstairs!

Yes but, reported as an Alexander Dennis Enviro400. Enviro means electric dont it. 400 means really scary

ENVIRO400EV is the electric version

Enviro doesn't mean electric. Alexander Dennis (and predecessor TransBus) have been making buses called Enviro since 2001.

Once again. The bus involved in this fire was a diesel engined 2015 Enviro400.

My remarks were intended to be light-hearted, and to be reflection of the views held by the hard of thinking.

Enviro is the bodywork style, came out about 2006

Replaced the Alexander ALX400 and Plaxton President, as ADL had merged by then via Transbus

The 400 is double deck 2 axle version, they used same numbers as ALX series except the long single deck ALX300 just became a long Enviro200

There have been diesel, hybrid, compressed gas, and electric versions

The buses between Reading and High Wycombe have history. Why I never sit at the back, there is warm and warm!

I came to this story via social media. The amount of people stating, quite confidently, that this was an electric bus was astounding. It seems any vehicle fire these days MUST be an EV according to these luddites, who never read beyond the headline and just let their prejudices dictate their belief.

This bus was a decade old diesel engined Alexander Dennis Enviro400.

An internal combustion engine vehicle is 20 times more likely to go on fire than an EV.

The past few weeks have shown that with numerous incidents including a fire of a car transporter carrying 9 new BYD cars. The "see, I told you these EVs catch fire" brigade were in full swing until the cause was revealed to heat from either a seized bearing or brake igniting the fuel tank of the transporter. Not only that, although all nine cars were destroyed, not one of the battery packs ignited.
