Not knowing specific examples here.. but the PFL S3 is some 65-70hp worse off than the RS, it's the natural pick to use for comparison I think. The S3 seems to get forgotten about. What annoys me is shows of the likes of Top Gear and now the Grand Tour, never seem to pay any interest to the Audi Sport series.
Perhaps these car journalists think that by using the term 'RS' as a less superior car in their review, they are bigging up the 'said car' given to them by a manufacturer for a 'honest' review for example.
It's like the RS3 was marked 95% of the time less superior to the Focus RS, nonsense. No surprise though when these companies are hired by Ford to get the publicity out there. If you aren't happy driving in a world of plastic, fast, just fast plastic then it has to be the Audi, it's still a Focus. I like Ford's, I love the idea of a 'Fast Ford', but it's nonsense to say it is superior to any Audi in all aspects, like build quality.
The RS3 was highlighted on Chris Harris' Top Gear review for being very fast, but boring.. it would be compared to a RWD BMW, not a fair comparison when you're trying to do nothing more than create a cloud of tyre smoke. What further irritated me, they used sound clips of the RS3 over the M2 footage
Looks like even the producers thought the review needed an added something
