The Veyron is a W16 made by bolting two Audi V8's together, definitely not a V6 in any way. And I'm fairly sure the Bentley Continental either comes with a V8 or a W12. Depending on the model.
However, the actual V6 cars mentioned are certainly not junk. In fact the XJ220 was faster with the Turbo V6 it got than with the V12 they were originally going to put in it! Also gotta remember rally cars, Metro 6R4 had a naturally aspirated 3.0 V6 producing well over 400 horsepower, and could do 0-60 in near F1 times, making it one of the most competitive N/A cars in Group B. The 1.5 V6's from 80's F1 were FAR more powerful than even the 3.0 - 3.5 liter V12's of the 90's, measuring in at 1200+ horsepower. Again, certainly not junk.
And Rotaries were so good that the FIA banned them immediately after Mazda got the first- and only Japanese win for the 24Hrs of Le Mans. (Noticing a theme with the FIA, they banned large displacement engines because Ford won with them in the 60's, and then banned Rotaries when Mazda won with them in the early 90's.)
In short, Junny, don't insult engine layouts and the people who enjoy them all because you don't like 'em. Some of the most dominant cars in history used very unorthodox methods to achieve that dominance.
