Japan's bargain Kei Cars

22:45 February 15, 2009 PST

Kei cars are a uniquely Japanese phenomena which began as a tax and insurance stimulus for the Japanese car industry in the post WWII era. Kei regulations only restrict physical size, engine displacement and power, so manufacturers have used every square centimetre and stacked it with as many advanced technologies as possible. The top-selling Kei car is Suzuki's Wagon R which offers a DOHC VVT 660cc engine, CVT transmission, engine stop-start, EBD, ABS, plus a Viscodrive coupling that provides on-demand AWD capability without electronics. Prices start at under 10 million yen (USD 9100) and the fully optioned Wagon R still comes in at under USD15,000. Maybe we need a similar stimulus based around size and emissions. Read More

Yamaha is developing a CVT (Constantly Variable Transmission) enduro machine according to recent patent applications. Conceived by Leonardo da Vinci 500 years ago, the CVT power delivery characteristics could well be a boon in slippery off-road conditions, particularly with some help from a computer. The CVT's biggest advantage is ensuring the motor is always running “in the power band” and as the infinitely variable gear ratios change, it should deliver one smooth rush of power from standstill to top speed.

Electrobike Pi: your pedal power gets an electric boost

By Loz Blain

Electric/pedal power hybrid bicycles make a lot of sense as commuters. With a small amount of battery power to augment your pedaling efforts, you can achieve extra speed and distance while leaving a minimal environmental footprint and paying next to nothing per kilometer. The Electrobike Pi is a fine example of the state of the art: packed with nifty technology in a design marked by its distinctive arch frame, the Pi is speed limited to 20 mph when powered by the 36V/500 watt electric motor alone - slotting neatly under the maximum power and speed figures allowable in California without a motorcycle license - and you can travel around 25 miles without troubling the pedals.

October 30, 2007 What a hoot! Piaggio’s new carving three-wheeler, with two independently suspended front wheels, opens up yet another whole new category of motorcycle – a category that will surely explode once people get a glimpse of the ability of these stunning bikes. The MP3’s triangle footprint produces some sensational handling characteristics, making it an exceptionally fool-proof learner/commuter bike – as well as a hilarious hooligan tool for more experienced riders. Gizmag spent an afternoon with the scooter that just won’t let you mess things up. Read More
