Weight-saving a priority for F1 BAR 005

The Lucky Strike BAR Honda F1 team unveiled its new 005 racecar yesterday in Barcelona, Spain. Designed by a team led by technical director Geoffrey Willis, the 005 is significantly lighter, smaller and more aerodynamically efficient than its predecessor, with a lower centre of gravity. The new Honda RA003e V10 is also lighter and smaller than the 2002 engine, with more power and an improved torque curve. Honda has become an official sponsor of BAR.

Weight-saving a priority for F1 BAR 005

Honda F1 project leader Takeo Kiuchi commented: "We believe that our additional support, increased branding on the car and the new power unit will be seen as symbols of our determination to compete at the highest level in F1." The Japanese manufacturer will continue to work closely with the Brackley team in the area of chassis development.

The monocoque of the BAR Honda 005 is constructed differently to that of the 004, with new internal bulkheads to reduce its weight. The seven-speed, semi-automatic gearbox is all-new, the maincase now being an aluminium investment-casting equipped with Xtrac internals. The revised suspension layout is also more compact, with laydown torsion springs. The fuel and cooling systems (the latter devised in collaboration with IMI/Marston) have also been refined.

BAR will again race on Bridgestone tyres this season and testing has begun this morning at the Circuit de Catalunya in Barcelona.

A run in F1's feeder GP3 category only caused his career to stall, but now back in Australia Mawson's S5000 title success has set that to rights
