Sep.19 (GMM) Honda's updated formula one car is not necessarily a push for extra speed at the Japanese team's home race next weekend, according to Jenson Button.



The car, which featured a visibly different front wing and other bodywork pieces when it debuted at the Jerez test on Tuesday, has already been nicknamed 'Fuji Special' because of the usual quest for a good performance in Japan.



Special engine upgrades with more horse power were in the past known as 'Suzuka Specials', in reference to the Honda-owned former home of the Japanese grand prix.



But after his teammate Rubens Barrichello lapped 1.4 seconds off the pace at Jerez with the new car, Button revealed that he is not expecting too much for Fuji.



"We've got a new aero package, which is not really necessary with this car," the Briton is quoted as saying by Speed TV.



Button added: "We've just got to keep our heads down and finish the season and concentrate on next year's car. We've got a few little things to try in testing this week, different ideas aerodynamically."



It has emerged that, among the McLaren and Williams-like 'bridge' front wing concept, Honda's new car also features forward and rear bargeboards, believed to be the first fruits of new aerodynamicist recruits Loic Bigois and John Owen.
