Profile  The old version of the Brazilian circuit incorporated most of the tight and twisty infield still present today, along with a balls-out, high-speed section. The original layout consisted of four fast corners, split up by long straights, in which the cars would remain flat out for around 20 seconds. With significant bumps throughout the lap, the track was considered very dangerous - especially by 1980 when cars were running ground-effect aerodynamics. That, and the encroaching favellas around the circuit, saw the Brazilian Grand Prix move to the more glamorous Jacarepagua circuit in Rio de Janeiro. When it returned in 1990 a $15 million redevelopment plan had stunted the circuit to today's layout. Interlagos literally means 'between the lakes' referring to two large manmade lakes built in the early 20th century to supply the city with water and electricity. The land on which the circuit stands was originally bought in 1938 by two property developers who intended to build houses on the site. When they discovered that the site was not suitable they decided to build a circuit instead, and as Sao Paulo continued to grow at an astounding rate it was not long before the track was surrounded by houses.  Full profile
