Crown Motors provided two Prius Hybrid Synergy Drive cars for former US vice-president Al Gore and his 'travelling global-warming show' in Hong Kong this week, says Toyota dealership spokeswoman Shirina Kwan. Gore went hybrid to promote his film An Inconvenient Truth, which opens on October 5, and attend the CLSA Investors' Forum. And the Toyota dealers gushed greenly. 'As a proud supporter of environmentally friendly technologies and initiatives that promote a cleaner living environment, Crown Motors was the first distributor in Hong Kong to offer a hybrid alternative for its customers,' it says. Which really isn't saying much. Beyond Crown Motors' Priuses and parallel-importers Richburg Motors' hybrid Toyota Alphards, the Hong Kong motor trade seems to have put the brakes on green cars. But Kwan speaks up for the five-seater Prius (above). 'The Hybrid Synergy Drive is able to achieve vastly improved fuel efficiency, reduced exhaust emissions and a reduced environmental impact throughout the vehicle's entire lifecycle,' she says. Perhaps we'll see more hybrid cars in Hong Kong, after all. In our dreams. According to local trade figures, 22 Prius hybrids were sold here in July, versus 71 petrol-powered Toyota Picnic and 70 Toyota Previa seven seaters. Where there's muck, there's brass, as we say on Lantau. Talking of green motoring, the e-mailed minutes of Clear the Air's monthly meeting on Tuesday suggest that the environmental group is mobilising against Hong Kong's idling motorists. A group organiser writes: 'We now have a small Clear the Air laminated sign for you to use that says: 'No Idling Engines' in Chinese and English.' 'It's based on the government's recommended way to ask drivers to switch off. If you want one - or are interested in joining a regular inspection schedule with other members to patrol our streets to get the message out - with a smile - e-mail email@example.com .' The minutes also say that volunteers 'will get training and patrol with at least one other Clear the Air inspector - and we can even take and post photos on a website to 'name and shame' the few who will not switch off'. That's great news for greenies. But motorists, please tell us how you would react if card-carrying environmentalists asked you to switch off your engines 'with a smile', as Friends of the Earth did in March 2000 (above). And how would you feel if you appeared on a 'name and shame' website? Should you stick up a counter sign saying: 'My other car's a Prius'? Tell us, on firstname.lastname@example.org . Finally, Ssanyong Motors Hong Kong (tel: 2117 2287) in To Kwa Wan offers the Stavic 2.7-litre turbo diesel multi-purpose vehicle this week for HK$228,000, says spokesman Gary Lai. The 165 brake-horsepowered five-seater (above) seems roomy inside, has rear-wheel drive and a five-speed automatic transmission with T-Tronic by Mercedes-Benz. 'The Stavic also is the first Euro IV-standard diesel MPV to launch in Hong Kong, and has the biggest maximum torque in its class.' Lai says. 'Even dogs can stay comfy with its rear air-conditioning.' Initial buyers can get HK$13,000 worth of DVD/video stuff - presumably with big woofers.
