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.
The BMW Sauber F1.06 is an all-new concept. The shorter and more fuel-efficient V8 powerplants exert a decisive influence on the architecture of the car. Due to the minimum dimensions for the design of the chassis as decreed by the FIA, the overall dimensions of the car remain almost unchanged.
