Lamborghini, Ferrari, Maserati, BMW, Bentley, Jaguar and Audi will display new models, many for their first showing in Australia.
BMW is holding the international unveiling of its 3-Series convertible in Detroit today, then will rush a car to the Brisbane show. It will go on sale in March, to be priced about $100,000.
BMW also will have its just-released M6 convertible, with a Formula One-inspired V10 engine, $295,000 and six-month waiting list.
Rival Audi will bring an early example of its new high-performance R8 coupe. Deliveries of the $300,000 car will not begin until September.
Brisbane has scored a coup by attracting displays from upmarket marques Jaguar and Lamborghini, which bypassed the Sydney Motor Show late last year.
At the top of the exotic list — and likely to be the most expensive car in the show — will be Lamborghini's $659,000 Murcielago LP640 coupe, making its Australian debut.
The Italian-made V12-powered LP640, a new-generation replacement for the original Murcielago, has a larger engine and more aggressive styling. It is claimed to be capable of 340 km/h, and can reach 100km/h in 3.4 seconds.
The show also will have the Australian unveiling of the production version of a smaller Lamborghini convertible, the Gallardo Spyder. Top speed 314km/h. Price $439,000.
Other high-speed Italians will include the Ferrari 599 GTB Fiorano ($574,000, V12 engine, 0-100km/h 3.7sec, top speed 330km/h), Maserati's two-door $248,500 GranSport and four-door $258,000 Quattroporte.
The 10-day show, at the Brisbane Convention and Exhibition Centre, will open on February 2. Adult tickets will be $16.
