Guess the author got to see the super secret results, cause the published results aren't matching the report.

They didn't beat the Yaris hybrid, but the Skoda, Seat, and Vovle diesels did do well. Which shouldn't be a surprise. Diesels can be clean. The cheaters just didn't want to spend the money for it, but now they are under closer scrutiny.
It was only on cold starts where the hybrids did worse. Being less volatile, there is less free volatile compounds to start with in diesel. Hybrids could be higher than petrols because they spin up the engine to a higher speed before firing; more unburnt fuel could be a result on start up. Then the hybrid group also included mild hybrids, which aren't different from a petrol on a cold start.
After that cols start, the diesel and petrol running emissions will be higher than the hybrid in most cases.

It wasn't just about the higher emissions. It was about defrauding consumers, and unfair competition for other car companies. If VW hadn't cheated, we could have had Honda diesels years ago.

Then the diesel option costs more, and most companies that offered a small diesel only had it in a more expensive trim.
It is our cheap fuel that keeps interest in efficiency choices low though.
