TWO of motorsport's most prominent sponsors, Mobil and Marlboro, have combined forces with Toyota Team Toms from Japan to grab a multi-million dollar stake in mainland China's fledgling car racing industry. Yesterday the two companies unveiled a two-car challenge for the Zhuhai Global Endurance GT Race scheduled for tomorrow week at the rapidly growing coastal centre. But more significantly, the three companies have struck a three-year deal which will see them take their place in the race again next year when it switches venues from the current 4.1-kilometre street circuit to a purpose-built Formula One circuit on the outskirts of the city. It is a clear message from Mobil and Marlboro that they see a bright future in motorsport in China and want to beat the rush. Developers of the circuit, which will be subject to a media site inspection on Friday, expect it to be completed by October next year and the GT Endurance Race is pencilled in as the debut event. It is also on record that the developers want an F1 race in 1997 and haven't ruled out hosting a round of the 500 cc world motorcycle championship either. Most of the ground work for the track has been completed and FIA inspectors are expected to conduct a series of inspections soon. TTT have clearly indicated that they want the 'we can all win together' philosophy to be an instant success by hiring four of the leading GT drivers in the world. Behind the wheel of the number one 650 horsepower SG Supra turbo will be this year's Le Mans 24-hour Race winners Yannick Dalmas and J. J. Lehto and driving cover will be former Ligier F1 driver Philippe Alliot and runner-up in the same race, Pierre Henri Raphanel. It will be a tall order for TTT to take on the mighty McLarens which have dominated the GT Endurance Series this year but they have spared no expense in ensuring the challenge will be genuine. Where they hope to grab a vital edge over the McLarens is their suspension setup. A team of TTT engineers have already been in Zhuhai studying the layout of the tricky street circuit. They hope that information will give them an advantage over the McLarens which usually race on purpose-built circuits. Meanwhile, the only Ferrari which will compete in next month's Super Car Race at the Macau Grand Prix will be sponsored by the Peak Cafe and Cafe Deco, two of Hong Kong's leading restaurants. The red Ferrari 355, which will be driven by Peter Worm d'Costa, is part of the prestigious Auto Becker Challenge Team of Germany. The Super Car Race will be the final race of 1995 for the Auto Becker Challenge Team and driver d'Costa will be looking to repeat last year's victory by Ferrari when he takes the starting grid on November 18. The Auto Becker Challenge Team represents Auto Becker of Dusseldorf, Germany's leading dealer in prestige motor cars. The team is led by Peter Buethe who was behind the successful Becker challenge at Mugello in Italy in August. D'Costa's Ferrari has been modified by Gerd Potreck who has incorporated aluminium into the chassis and main frame to make the motor car more efficient. 'The opportunity to have your products associated with such a well known symbol of success doesn't come along often,' said Martin Allies, director of the Peak Cafe and Cafe Deco.
