Red Bull Racing’s chief technical officer Adrian Newey believes the rule-makers need to give more consideration to aesthetics when they draft new regulations. His comments come ahead of major changes for 2014 and fears the new cars could be ‘ugly’.

“It’s the regulations that define the car,” he said in an interview with the official F1 site, “and, of course, ideally the car is fast and has a stylish design.

“But everybody in the paddock will give a fast car preference over an attractive car – that’s the way it is.

“[So] yes, for me it would be good if a bit more consideration was given to aesthetics in the drafting of the regulations.

“But fast is paramount over beauty.”

Meanwhile, when quizzed on if one team might find a big advantage in 2014, Newey replied: “The aerodynamic changes are big [next season], but they are smaller than the changes we had in 2009. There is the chance that one team comes up with a car that is better than their rivals’, but on top of that you have the engine changes and what is absolutely unclear is whether one engine manufacturer will be able to come up with a significant advantage.

“But the car that will brush aside all others will be a car having the combination of good engine and good chassis – if one side is letting you down you will have a problem.

“But who will come up with the ideal combination? That’s the big guessing game for all of us and will add spice to the 2014 season.”
