( CNN ) -- The checkered flag has only just fallen on the final Formula One race of the year in Brazil but the sport 's top car designer is already predicting a spicy 2014 season . Adrian Newey is the man behind the Red Bull racer that has powered Sebastian Vettel and the team to four straight world championships . But the Englishman is not taking Red Bull 's dominance for granted as major rule changes loom on the horizon . Next year , each team must package its car around a new turbo engine as well as complying with aerodynamic rule changes which will mainly affect the design of the cars ' front and rear wings . `` The aerodynamic changes are big , '' explained Newey to Formula1.com . `` But they are smaller than the changes we had in 2009 . `` So yes , 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 . `` 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 . `` 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 . '' Red Bull will continue to be powered by Renault while Mercedes and Ferrari will pit their new 1.6-litre , V6 engines against the French engine manufacturer . The 2014 cars will also rely on more hybrid power harvested from Energy Recovery Systems ( ERS ) . While these elements of the car are out of Newey 's hands , the Englishman , who says he has received offers to join rival teams , remains in charge of Red Bull 's car design as the team 's chief technical officer . There has already been speculation within the sport that the 2014 cars will be less easy on the eye than this season 's sleek racers . It 's a theory that also irks Newey , who still uses a drawing board to sketch out the design of his peerless machines . `` Ideally the car is fast and has a stylish design , '' the former Williams and McLaren designer continued . `` But everybody in the paddock will give a fast car preference over an attractive car -- that 's the way it is . `` 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 . '' Newey and his team of more than 100 engineers have been working on Red Bull 's 2014 for many months , even while juggling the demands of winning current championships . Amazing brain . But the Englishman , rated as the sport 's leading car designer , was still willing to share some tips on preparing for a major rule change -- even if there could be a slight danger that rivals such as Ferrari , Mercedes and McLaren might just pinch some of his ideas . `` The first thing that you do is to read the regulations -- very , very carefully , '' he explained . `` You try to read what they actually say , rather than what they intend to say , as this is not always the same thing . `` After that I 'm actually breaking it down into bite-size chunks . Then you try to understand from the regulations the aerodynamic and mechanical packaging that appears to be the best solutions for those different areas . `` You go away and research them and at some point try to bring it all back together again . For me that is the important bit : the end product should be a whole and not pieces thrown together into one cluster . `` Does it still look a good idea after 24 hours ? That decides whether it gets a tick or a cross . `` Actually , you develop a sensibility for that procedure . The brain is an amazing thing : you might be doing something completely different -- maybe making a cup of tea -- and suddenly you know right from wrong ! '' The most coveted designer in Formula One will find out whether he has got it right or wrong when testing for the new season begins next January .
Red Bull car designer Adrian Newey says 2014 rule changes will spice up new season . He says it is a `` guessing game '' which team will have best engine/chassis combination . Newey says he would like the rules to consider car aesthetics more than they do . Englishman says he has a `` 24-hour '' rule he applies to all his design ideas .
