WORLD launches from Rover, Mazda and Hyundai will take centre stage at next week's London Motor Show. Rover will reveal its replacements for the 200 and 400 - the 25 and 45 - in public for the first time, claiming the two models represent 'a milestone' in the evolution in the mark.

However, both Mazda and Hyundai are keeping their vehicles a closely guarded secret until the show opens to the public on Wednesday. Mazda is launching its new 626 saloon, while Hyundai is unveiling its seven-seater MPV. Meanwhile 'UK debut' is the key phrase at the Earl's Court show where many fleet managers will be able to see new models for the first time following their debuts earlier this year at other motor shows - particularly in Detroit, Geneva and last month in Frankfurt.

Among the 25 UK debuts are Vauxhall's long-awaited make-over of the Omega, plus the Astra Coupe, the new Neon from Chrysler, Peugeot's executive sector contender the 607 and the SEAT Leon. For those interested in small cars there's a dearth of new-to-the-UK product including the Fiat Punto, and the facelifted Ford Fiesta, Volkswagen Polo and Citroen Saxo. Wednesday, October 20, is fleet preview day aimed at attracting fleet bosses and senior management to see the product and meet with key members of manufacturer's corporate sales departments.

A show spokesman said: 'The fleet preview is the day that is set aside for the fleet manager to come along and see the vehicles and meet the top people from all the manufacturers in a relaxed atmosphere. The entry price on that day is deliberately higher on the Wednesday so there will be fewer members of the public there and give it a sense of exclusivity. No doubt there will be some big business done on the fleet preview day.'
