Lotus E21 Renault

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

It seems that they are not able to compromise too much rear downforce unlike rbr, fer and Merc could.

Bianchi feels "we are very quick to the Lotus" Re: "Yes, we're very quick compared to them, we saw them struggle to get past you"

Could Lotus gear up longer on 7th???

Vmax Bianchi : 295 km/h Vmax Lotus : 293 km/h

But during race one car only can activate his DRS.

Lap time Bianchi : 1'53" 482 Lotus : 1'50" Who will have the blue flag :lol:

Nick Chester about the car, the development, the DRD, 2014, the new wheelbase etc
Welcome, Nick. There's a lot going on at Lotus at the moment. You've got the double DRS running this weekend. You've got a long wheelbase car, apparently, for Monza. Can you shed a bit of light on your thinking for this final part of 2013 and what kind of statement that makes?

Nick CHESTER: Well, we're still trying to develop very hard to give ourselves a very competitive run until the end of the year. The passive drag reduction system we've been working on for a while. We targeted it for Spa and we've run it through P1 and we've learned some more with it. I don't think we'll carry on through this weekend with it as we didn't get enough dry running to get where we wanted in P1. We are targeting this strong development until the end of the year and the long wheelbase for Monza is part of that. So we are going to keep bringing developments through Monza and then the following races as well. There are certainly developments also planned for Singapore and Korea.

Like everyone else here, you're obviously juggling the requirements of 2014. Do you have what you need to build a winning car in 2014?

NC: Yeah, we do. We started the design very early, we've been designing for over 18 months on the 2014 car. So that's given us a good head start and in a way that's meant that we could develop our 2013 car for longer through the year because we're in such good shape with next year's car. As Pat said it's going to be a very interesting year in 2014. It's the biggest rule change I've seen while I've been in the sport. Trying to optimise a car around what's a very different power plant with very different cooling, it's quite a big challenge. It is going to be interesting.

Q: (Edd Straw - Autosport) Nick, the long wheelbase car, what's the reasoning behind introducing that and how will you be doing it? Do you need to make some monocoque changes or can you do it a slightly easier way?

NC: Well, we've wanted to do it because we've seen there's a performance gain associated with it. The way we're going to do it is with a front suspension change.

Q: But there's homologation to be done?

NC: Yeah, that's already been done.

Q: (Marc Priestley - F1 Times) Question for Nick and Tom: firstly, Tom, both you guys have used this passive DRS-type system on the car today. Tom, do you expect to use it any more this weekend. Nick, you've already clarified that you won't, but is it something that you will continue working on? Do the 2014 rules mean that it's a viable concept to continue developing?

TMcC: So, today we performed a lot of tests on some new parts and the system actually performed better than we were expecting. It's still not at the stage where we think we're going to race it, even though we are pretty tempted at the moment, so there's plenty of engineers looking at a lot of data. We'll make that decision later on tonight. With regards to next year, any system that you can use to help reduce drag will always help you, so yes, it is part of the consideration for next year's car.

NC: And the same for Lotus; obviously anything that drops drag is a useful thing to have, so it's an interesting direction to pursue.

Q: Just for clarity, the reason not to continue with it for the weekend, is that because the downside of it, not switching properly, outweighs the possible gains of having it?

NC: Partly, and also because we didn't have a full dry session, we couldn't get the normal feedback we would like on it and all the measurements we would like, so it just left us a little nervous after P1 that we didn't want to go into the rest of the weekend with something that may give us a problem, particularly when the car's already competitive and we didn't want to risk having a problem in P3 or qualifying with it.

Q: (Edd Straw - Autosport) Nick, the wheelbase change, any concerns that will have a detrimental effect on the good tyre management you've seen from your car? Obviously it will slightly change the way you're loading up the tyres.

NC: Yeah, we don't expect so. If anything, it should make the car a little bit more stable, a little bit easier to drive, it could even give us a small tyre management advantage so we think it's the right thing to do and we're looking forward to bringing it to Monza.

So wheel fairings have also evolved, especially the hot air outlet

the silverstone wheel fairing/duct appears to have more exposure for the exhaust air to contact the rim. tire temp tuning aid?

That seems plausible.

Do you guys think it's possible that's what's caused Raikkonen's brake failure today? He has been struggling to get front tyres up to temp and if they've closed the brake drums to help him with that, it might have been a bit too much?

Was thinking that myself. They say the lotus works better with with hotter tyre temperatures and Spa was a bit cold. Seems a bit amateur to try something like this. Surely they should have known they would be overcooking their brakes , even without this botch job, because of their grid position, being behind cars for a lot of the race. Reminds me of the type of rough upgrade that McLaren did with cutting chunks out of their rear floor.

Lotus are running out of ideas if this is the type of approach they are taking. But I guess Allison took all the new ideas with him. Lotus might struggle for the rest of the season, and in turn Raikkonen will leave.

Really disappointed Kimi's great finishing record has ended like this.
F1 is dead.

According to Boullier, there was a tear-off that blocked the brake duct inlets. They took it off at the first pit stop but the disc was already overheated and the whole thing failed some laps later. That happened only on one side - left-front - so the idea of a bad cooling solution is out of the ecuation. It was a case of bad luck.

That's a real shame. Must have happened on the warm-up lap as well, because it was pretty much from the start.

looking forward to monza, it will be interesting to see if they can improve with longer wheelbase, if this will not be successfull then they can forget on championship

Do we have any official source on this longer wheelbase ?

If you look on the previous page you will see Nick Chester talking about it in the press conference. It is already homologated and will be used in Italy.
