ITALIAN Formula Three Championship winner Giancarlo Fisichella may have declared the Guia street circuit the toughest he has ever driven - but he brought the track to its knees with a dazzling final qualifying session yesterday in the Portuguese enclave. Fisichella clocked two minutes and 17.96 seconds ahead of tomorrow's two-leg Macau F3 Grand Prix, a full 1.04 seconds clear of his nearest rival, Sascha Maassen. Driving a RC Motorsport Opel-powered Dallara F394, Fisichella shows a distinct liking for the special demands of street circuits. He won the Monaco street circuit F3 Grand Prix earlier in the year. Quickest in the first qualifying session on Thursday, the diminutive Italian simply took up from where he left off in a scintillating display of driving which stamps him for greater things. His talents have already not gone unnoticed - he has the prospect of a testing contract with the Formula One Team Minardi next season. German Maassen is quickly acquiring a reputation as a nearly man and yesterday was no exception. Third in the Marlboro Masters at Zandvoort and Monaco earlier this year, Maassen qualified second on the grid here last year. Driving a Mild Seven WTS Racing Opel-powered Dallara F394, Maassen clocked 2:19.00, three tenths of a second clear of last year's winner Jorg Muller. German F3 champion this year, Muller struggled during the early stages of qualifying in his RSM Marko Dallara F394 before striking a clear run to claim third slot on the grid. Austrian Phillip Peter, driving an Elf Team-Formel 3 Dallara F394 with a Fiat power plant, was well placed during the entire session but like many of the drivers put in a late 2:19.40 to cement fourth place on the grid. Eight of the top 10 qualifiers are all previous visitors to Macau which clearly underlines the importance of laps on the track. But one name stood out like a beacon in the top 10, that of Ralf Schumacher, the younger brother of Formula One world champion, Michael. Bearing a striking resemblance to his older brother, Ralf stormed from the depths of the 28-car field to zoom into sixth place behind the wheel of a Mild Seven WTS Racing Dallara F394. He has a tall order to emulate Michael who won the race in 1990 giving away 1.8 seconds to pole-sitter Fisichella. The only other newcomer to figure in the top 10 was Argentinian Norbeto Fontana in an Opel-powered Dallara F394. He clocked the identical time as Schumacher, 2:19.71. Mobil 1-Paul Stewart Racing driver Jan Magnussen's glittering season of 14 race victories lost its lustre when he collided with the Armco at Police Bend 40 minutes into the session. The Dane will have his hands gripped to the wheel when he tackles the bend again today in untimed practice having spun out at the same place earlier in the session yesterday. He produced a best time of only 2:20.99 which banished him to 18th place on the grid. The British F3 champion will need to produce a drive of late F1 champion Ayrton Senna proportions to win from 18th place on the grid. Ironically, it was Senna's record of 12 F3 victories set in 1983 that Magnussen overhauled this year. But the day belonged to the 20-year-old Fisichella who grew in confidence with every lap. 'It was simply a perfect lap. I had just come back on the track after going into the pits for a five-minute rest. I came out aggressive, struck no traffic and everything worked perfectly,' said the Italian. The first 15-lap leg of the F3 Grand Prix is scheduled for 11.55 am.
