Korea here we come - what to expect in Yeongam 18 Oct 2010
The addition of a brand new circuit to the F1 calendar is always an exciting prospect and this weekends inaugural Korean Grand Prix in Yeongam certainly has all the ingredients for an entertaining race.
Its an anti-clockwise track with a diverse mix of corners, long straights, and genuine overtaking opportunities. But what are the challenges faced by the teams when getting to grips with a new venue and how do they prepare for the unknown? Renault give their take on the matter
Our initial preparations began many months ago when the FIA provided all the teams with a detailed circuit map, explains chief race engineer Alan Permane. From this we were able to create a digital representation of the track and then asked our drivers to add what they believe to be the correct racing line.
With a virtual lap in place, the team has spent the last month running virtual simulations to get a head start on the set-up required for Yeongam. The simulations allow us to assess the best aero levels, suspension settings, ride heights and even sensitivity to fuel load, confirms Alan. There are lots of unknowns, such as the grip level of the tarmac, surface bumps, or the camber of the road, but we still have a fairly good idea of the set-up we will need before we arrive at the track.
So what have the simulations revealed so far? Well, the projected lap time is 1m 44s and the cars will be on full throttle for 55 percent of the lap and on the brakes for 20 percent. The average speed will be 195 km/h, with a top speed of 315 km/h on the 1.15 km straight between turns two and three. As for the corners, turn eight is probably the quickest of the lap with an apex speed of 235 km/h, while turn three is the slowest corner, expected to be taken at just 65 km/h.
This level of preparation means that the engineering approach to Friday practice wont need to change massively from the norm, although the drivers may run more laps in FP1 to learn the track. For the engineers, one of the main priorities will be determining the gear ratios, especially for second, third and fourth gears. Although the ratios for FP1 have already been selected, it will make for a busy lunch hour in the garage if changes are needed for FP2.
In terms of the aero set-up, it wont be far off the settings used at Suzuka: The downforce needed will be on the high side and we plan to run with the same wing package we used in Suzuka, confirms Permane. There are a couple of high-speed corners, such as turns seven and eight, which remind me of turns five and six at Sepang. They involve a quick change of direction and we expect turn seven will be flat, while turn eight will be almost flat. It will also be important to maximise the F-duct for the long straights because there are a couple of good overtaking opportunities into turns one and three.
Another significant characteristic of the lap is the number of low-speed, technical corners, such as the sequence from turns four to six or turns 15 and 16 towards the end of the lap. Getting the right balance through these corners will be critical for a quick lap.
For these corners you need a nimble car with a good turn-in and good traction, says Permane. Its important the car works well in these sorts of corner because its where the most significant lap time gains can be found.
