FLASHY full-colour advertising spreads last week announced the arrival in the territory of the car of the future, but those with chequebook at the ready were sadly disappointed. The car in question - the Mercedes-Benz F100 - has, in fact, little future, as it will never go into commercial production. A developmental vehicle, it was created to test innovative design and technology concepts which will eventually be used in future production models. And there are plenty of innovations, as visitors to The World of Mercedes-Benz Show at the Convention and Exhibition Centre have found. The F100's five-door body has no central pillars and the driver's seat is in the centre line of the vehicle to ensure greater safety in the event of an accident. Perfectly attuned to the Hongkong way of life, the F100 features a voice-activated telephone in the impact absorber on the steering wheel, while the passenger compartment is equipped with a telephone, a telefax, a refrigerator and a second air-conditioning unit. The F100 seems to have everything but auto-pilot - although someone's probably working on it. Satellite communication with traffic master computers gives the driver an optimum route recommendation for reaching the destination, which is continually updated as the car gets closer. Information on traffic accidents, parking facilities and petrol stations is also given. With safety in mind, a video camera installed at the rear of the car extends a screen inside the vehicle to indicate hidden objects as the driver is reversing. All this and it is environmentally friendly. All vehicle parts are reprocessable and reusable, including plastics, bumpers, tyres, batteries and catalytic converters - with no use of asbestos or CFCs. The low drag coefficient of just 0.24 minimises fuel consumption and pollution. So what more could you ask for? The real McCoy? The World of Mercedes-Benz Show at the Convention and Exhibition Centre closes this evening.
