Formula 1 looks set to prevent the cars of 2013 from being as "ugly" as the 2012 season's field.Pirelli chief Paul Hembery recently called the 2012 generation, mainly featuring an awkward 'step' between the front of the monocoque and the nose, as "pig ugly".The odd look is the result of a compromise reached after the FIA decided to lower the tip of the nose in the name of safety.'NOT THAT NICE'It emerges that it was Red Bull, whose Adrian Newey pioneered the high chassis underside philosophy, who pushed for the monocoque height to remain the same as 2011. The team did this so that small teams, like sister squad Toro Rosso, did not have to come up with entirely new monocoque and front suspension designs.World champion Sebastian Vettel admits that the 2012 outcome "doesn't look that nice". He said: "For next 2013's cars, the steps will be gone."Nick Heidfeld added: "Yes, I'm sure the FIA will make a few changes in 2013, so there's not such a huge hump. On the other hand, it's like a few years ago when the rear and front wings were changed; it doesn't look quite so bad once you get used to it."Of course, you'd always prefer something that looks nicer."
