The IAA International Motor Show held every other year in Frankfurt promises something for everyone, from the car enthusiast who likes a brisk drive to the environmentalist looking for better fuel efficiency.

BMW AG is hustling to market with its Z8 open sport car - the production version of the Z07 concept car first launched at the 1997 Tokyo Motor Show.

The Z8 doubtless will be Frankfurt's darling.

The vehicle is built using an aluminum space frame and aluminum body panels; under the hood, it comes equipped with the 400-hp DOHC V-8 filched from the new M5. The car comes standard with a removeable hard top.

The appearance and performance enhancements of the 9-3 Aero will show up on the 9-3 SE 5-door and convertible, but 9-3s will not wear an Aero badge.

Audi AG completes its S high-performance range with the debut of the S6 and S6 Avant. This sedan and station wagon duo combines performance and a modern appearance, Audi says. The vehicles are equipped with a juicy, 340-hp version of Audi's 4.2L V-8, along with quattro permanent all-wheel-drive.

"The C-segment is the biggest in Europe, and models in this sector often define the personality of the brand," says Ian Gibson, president of Nissan Europe. "This will mark the first time Nissan has had a European-built contender here, and it will accelerate the communication of our brand value."

The vehicle will be equipped with a new line of engines ranging from 1.5L to 2.2L, including Nissan's new direct-injection diesel technology.The Japanese aut omaker additionally will preview the Tino, a multi-purpose vehicle variant of the Almera.
