Korea here we come - what to expect in Yeongam

Korea here we come - what to expect in Yeongam

The addition of a brand new circuit to the F1 calendar is always an exciting prospect and this weekend’s inaugural Korean Grand Prix in Yeongam certainly has all the ingredients for an entertaining race.

It’s 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 won’t 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 won’t 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. “It’s important the car works well in these sorts of corner because it’s where the most significant lap time gains can be found.”

Korea won’t be easy for Red Bull says Chandhok

Former HRT driver Karun Chandhok has given some insight into the new Korean Grand Prix circuit, explaining that in his opinion, this is one circuit that wont favour the Red Bull duo of Mark Webber and Sebastian Vettel as much as some of the others on the schedule, such as the recent Suzuka circuit in Japan.

Speaking to Reuters in an interview, the Indian racer explained that due to the long straights in sector one, other teams such as McLaren or Ferrari, could have an added advantage over the red Bull contender and may even be lucky enough to snatch victory away for themselves.

"It's going to be very slippery, very low grip, I would imagine. The Red Bull is quick everywhere. But I think here, specifically though the first sector of the lap with the three long straights, they may not be as quick as some of the others. Ferrari and McLaren will be strong.”

"Even if the Red Bulls qualify one-two, it will be interesting to see because of the long straights in sector one if they hold that advantage into turn four on the first lap. I do think the gap will be closer, I think the gap will be close enough that if Alonso or Lewis or Jenson dig deep they could sneak a win out of it."

He also explained that out of the five drivers still gunning for the 2010 crown, only two, Mark Webber and Jenson Button, actually called to get his opinion on the track after he completed a demo run there for Red Bull recently.

"You'd expect people to be calling, really. I would have done that. Even driving down at the back of the grid, if for example somebody else had gone off there to Korea. I would have been grabbing at their ankles to find out as much as I can about it."

However, it appeasers as if they will all be relying on info from their sophisticated simulators to prepare them for what’s to come instead.

"To be fair, a lot of people have very good simulators and they have a lot of faith in their simulators and simulation software. I think a lot of them tend to believe that more than anything else."
