Monza a stiff test for engines - BMW.

BMW motorsport director, Mario Theissen has revealed that Monza is a 'special' race for them.

Theissen added that what makes it stand out is that it is a real test for engines - right up there with the likes of Spa and Indianapolis.

"Monza is an outstanding circuit for engines and, as such, is always a very special Grand Prix for BMW," he confirmed.

"The cars are flat out for 69 percent of the lap, the highest full-throttle ratio of any Formula One circuit. Monza ranks among the top few circuits where engines have to operate on a sustained full throttle over various parts of the track.

"On the current F1 calendar, there are three similar full-throttle sections which demand everything of the engines. Topping the league is Spa [1,821 metres, if Eau Rouge is taken flat out]. Almost on a par is Indianapolis [1,820 metres], followed by Monza [1,268 metres].

"When it comes to speed, Monza outstrips all other race tracks. In 2004, Juan Pablo Montoya set an F1 record in pre-qualifying when he recorded an average speed of 262.242 km/h. Antonio Pizzonia also claimed a Formula One record with a top speed of 369.9 km/h during the race.

"For the Italian Grand Prix, we will have new BMW P84/5 engines, as scheduled.

"In Turkey, we had a good chance of scoring points before we suffered a disappointing setback. Our goal, however, remains unchanged; we want to end the 2005 season with Williams with some good results."
