MELBOURNE, Australia - Ferrari president Luca di Montezemolo has warned against "technical trickery" as Formula 1 enters its new and uncertain era.In a letter to Ferrari fans ahead of the season-opening 2014 Australian GP Montezemoloexpressed concern that the rule changes could turn the likes of is own driver Fernando Alonso into "taxi drivers" rather than racers.F1 has swopped its 2.4-litre V8 engines for 1.6 V6 turbo power units with complicated energy recovery systems and an emphasis on fuel economy.VIGILANCE NEEDEDMontezemolo said: "Such an important set of changes to the regulations is bringing some grey areas, for example fuel, software, consumption. I am fully expecting the International Automobile Federation to be vigilant to avoid any trickery such as has also taken place in the recent past but must not happen any more for the good of this sport."Teams are allowed only 100kg of fuel to last the race; it was 150-160kg in 2012. The governing federation is responsible for policing fuel loads and flow rates.F1 has had numerous scandals and controversies over the years, with Red Bull hitting out at accusations it was using some form of banned traction control in 2013.Montezemolo said the new season had more unknowns and uncertainties than in the past.‘DIFFICULT TO FOLLOW’He added: "In essence it's a complicated car that will also require a different driving style. It will also be a difficult championship for the spectators to follow. The drivers will have to take care that they do not wear out their tyres and save fuel..."I hope they don't turn into taxi drivers - and I say that with the greatest respect to taxi drivers, but they obviously do a different job."Montezemolo said Ferrari had the best drivers - Spaniard Alonso and returning Finn Kimi Raikkonen, each a Formula 1 champion - and a strong team."We're also putting into practice an plan of intense development which can count on the fact that the data from the wind tunnel have been confirmed by the track comparisons, something that has not happened in recent years."Ferrari, the oldest and most successful team in F1, was third overall in 2013 behind Red Bull and Mercedes.Stay with Wheels24 for the first race of the 2014 F1 season in Melbourne.
