Japanese automakers on Tuesday unveiled several new sports cars at an auto show in Detroit, including Nissan Motor Co.'s new version of its Fairlady Z sports coupe that was a big hit in the 1970s and 1980s.

At the annual North American International Auto Show, Nissan unveiled a concept model for a new version of the Z sports coupe, with an engine displacement of 3,500cc and an output of more than 260 horsepower.

The new Z car is scheduled to go on sale in Japan and North America in mid-2002, priced at less than $30,000, according to Nissan officials.

Mazda Motor Corp. unveiled the RX-8, the successor to the RX-7 -- the only rotary-engine car in the world.
