General Description
Undulated with a good mix of fast and
'slow' corners, Kyalami is perhaps one of the most technical of all the circuits in South Africa. If you do a count there are 9 left hand corners and 5 right-handers. The track is 4.261km long and runs anti-clockwise, a left-hand track, so to speak. Even though it's seen a fair share of fatalities over the years, Kyalami is still regarded a safe track by local standards, with ample run-off areas and kitty litter to stop you.
Picking the right lines and smooth driving are crucial if you wanna go quick at Kyalami. Some people say it's a 'stop & go' track because you come from high speed sweepers into relatively tight corners. My general advice is to put that mentality out of your mind. The easiest way to make up time at Kyalami is getting off the brakes a fraction earlier in most turns. The track is wide enough to carry relatively high corner speeds everywhere.
As a rule of thumb, any lap time below 2'10" at Kyalami can be considered relatively fast. Fast as in faster than 99.9 percent of excellent road drivers would be capable of first time out. Anything under two minutes is seriously quick, no matter what class you're talking about. Lap times below 1'50" can only be explained with ample use of vulgar lingo.
And then compare that to F1 testing at Kyalami in February 2000 when Villeneuve, Zonta, R Schumacher and Button were all in the 1'23"s...
Track History
Kyalami was originally built in 1961 as a 4.104km track. The track was widened and resurfaced in 1968, the length being marginally extended. The circuit has been used for Grand Prix and Formula One races and has hosted the South African Grand Prix many times.
When some of the F1 teams boycotted the track in 1985, the circuit was heavily revised and rebuilt, using only part of the previous track. Crowthorne, Barbeque and Jukskei sweep were either eliminated or heavily modified. Formula one abandoned the rebuilt circuit in 1993 after just two races and a bankruptcy on the part of the promoter.
The track has also played host to five rounds of the World Superbike series from 1998 – 2002 and again in 2009 when the track was altered again by removing the much hated
“Bus Stop” chicane and replacing it with a fast right hand kink as the penultimate corner, turn 13.
Kyalami also hosted the South African round of the A1-GP series for the first time in 2009.
