BMW Sauber F1 Team rolls out in Valencia.
Munich/Valencia, 17th January 2006. The BMW Sauber F1 Team steps out onto the Formula One stage. Just after nine o'clock this Tuesday morning in Valencia, Spain, the BMW Sauber F1.06 was unveiled before more than 500 journalists and guests in the futuristic Ciudad de las Artes y las Ciencias (CAC).
At 13.00 hrs the first car of the BMW Sauber F1 Team will make its debut on the Circuito de la Comunitat Valenciana Ricardo Tormo.
Also ready to launch into the new team's maiden season in the FIA Formula One World Championship are BMW Sauber F1 Team drivers Nick Heidfeld (28, Germany), Jacques Villeneuve (34, Canada) and newcomer Robert Kubica (21, Poland), who takes on the mantle of test and substitute driver.
New engine.
Revolution, not evolution was the watchword when it came to the Formula One engines for the new season. The 3-litre V10 units of the past are being replaced by 2.4-litre V8 engines. This switch calls for totally new concepts. The new V8 engines are heavier, shorter and, due to a 600 cc reduction in capacity, have lower output and fuel consumption. "Lap times," estimates Theissen, "will go up by around two to three seconds, though spectators will hardly be aware of it. The drivers, on the other hand, need to adapt their driving style. To put it simply, they will have to attack corners less sharply to get the most out of the power available."
The different firing sequences and intervals compared to the V10 have led to a completely new situation in terms of vibrations. With a speed range that exceeded 19,000 rpm, the V10 hit a critical zone between 12,000 and 14,000 rpm. However, the engine spent very little time in this problematic band and smoothed itself out again as the revs were stepped up. But it is precisely here that the V8 encounters problems. Its vibration curve enters challenging territory later than the V10, starting at around 16,000 rpm and becoming more critical from there, which can impact on the stability of vehicle components. And, like its predecessor with two extra cylinders, the BMW P86 V8 engine also has to last for two grand prix weekends.
