I know...I didn't say exclusively, just that they are used very widely, and are efficient.

T-belts are fine, if they can be easily replaced. This shouldn't be a problem with a three cylinder mounted transversely. There should be plenty of clearance.

Also, it is helpful if the engine is non interference. Being so will allow stretching the recommended change interval without concern of catastrophic damage if it does go.

(Seems really good for generator or P&G-use tho.)

You did say "EVERYBODY" - and actually you are right too However car makers need to be more honest about how often they fail and need replacing vs. the benefits they bring in terms of weight and noise.

On the plus side for a TDI owner, replacing a belt early means you will replace the cr@ppy factory water pump at the same time

On the contrary, the vast majority of new engines use chains now including Ford. Even the Japanese moved away from T belts years ago. I can't believe they decided to cheap out on such a critical component.

Agreed, glad my 3cyl has a chain although it can be noisier.
I know a couple people with Aveos their fuel economy is "not all that"

Here in the US, IMO fuel economy cars are never the bread and butter;

it's still trucks and SUV's , which are more or less now called crossover

vehicles. Seems the vast majority wants big flash rides they put

themselves deep in debt for.
