When you are responsible for many Formula One World Championships and devastatingly fast supercars such as the new McLaren MP4-12C, you're entitled to speak your mind. The executive chairman and part owner of the McLaren Group, Ron Dennis, has earned a reputation for his outspoken opinion and this time directed his criticism toward the venerable Bugatti Veyron by calling it a 'complete piece of junk'.

The 63 year-old was being interviewed by Arabian Business when he said he could not even find a single aspect of the Bugatti Veyron that makes him feel good and called it 'pig ugly'. He also commented that the Veyron can't handle very well.

Dennis then went on to refer to a BBC Top Gear comparison of his previous supercar, the McLaren F1, against the Bugatti's technological tour de force. He described how the V12-powered F1 trounced the 16-cylinder Veyron so many times off the line that the filming crew got frustrated because his car was supposed to be beaten. Eventually the Veyron stopped dropping its clutch on take-off and was able to catch up to the McLaren F1. The Bugatti Veyron is powered by an 8.0-litre, quad turbo engine making 736 kW. In contrast, the McLaren F1 had a naturally aspirated 6.0-litre kicking out 468kW.

It will be interesting to see Bugatti's response to these comments made by Ron Dennis.
