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.

The LWB had the same results as the short one and it left room for further improvement, so it wasn't useless.

Looks like a frustrated Raikkonen fan. :mrgreen:

LWB car is born in the newly installed simulator and is a very important change.
The success of Lotus's long-wheelbase car will be a key barometer of the team's technical approach to the 2014 Formula 1 campaign, according to team principal Eric Boullier.

The long-wheelbase version of the E21 will run for the first time at next week's Italian Grand Prix and its development has been driven by the team's driver-in-loop simulator, which came online last year.

It is the first time Lotus has used the simulator for such a major change after the team's vehicle dynamics group suggested doing so.

Boullier believes it is important to try the long wheelbase car as it will validate the way the simulator is being used as a key part of the development process, particularly with a view to next season.

"We have to do it because we have to test our system," Boullier told AUTOSPORT.

"The decision-making process is now much more complex because it includes the simulator, which gives more importance to vehicle performance. But we have to see if it works.

"It [the change] is vehicle performance driven. We had to test after to make sure there was no downside on the aero and it looks like there is actually some upside.

"In the end, the driver likes it in the simulator, so let's see if this new way of working is delivering."

Wow. It's new is it? I never knew the effect that bold could have on a piece of text. You should write press releases. :D

Meanwhile, altering the wheelbase of your car is something you only do when you've got something fundamentally wrong. It's a very expensive thing to do and the changes they've made around their exhaust area have been far more fruitful - as they have been for RB and Sauber. They've been best of the rest creatively have Lotus, minus what they can spend versus other teams obviously, but spinning their wheels expensively retrofitting mechanical parts on the car one of which hasn't worked and the other which failed crash tests hasn't helped. While Red Bull had a new nose that needed crash tested that's something you'll never see them doing.

They spent a massively disproportionate amount of time, effort and money.
You dont know that. The F-duct was even more important in 2010, it was a must have, but few people worked on it in enstone, very few people according to the sources. I dont think they spent a lot of money on the DRD. The car's developpement didnt stop during that. they brought important updates just after that.
You are right, but time=money aswell, I agree they didn't invest everything to DRD, but I'm just curious if we gonna ever see DRD again in next season, if they can get this thing working, then the DRD may be the "biggest" advantage because it looks like it will be hard to copy it...

again .
You test one thing in the simulator then go to the track and try if it correlates ....if it does your process is right?

don´t you think it is just simply :oh we got a car wich is a handful and both drivers ask for more stability and elongating the wheelbase will inevitably calm the thing down? simulator or not?
would you be able to find out just how much you need to elongate? which is optimum? or best compromise? i think you can go a long way here with a good gut feeling -the question here is how much is to be found on top of this with the driver simulator approach... :roll:

LWB is clearly an upgrade that's only meant for Romain...

Kimi was awesome in SWB.....as he has been all season long. Closest challenger to Vettel.

Image Kimi begun struggling with tires long time before Lotus brought the LWB car / Grosjean started to qualifiy just behind the RBR and the Mercs and startted to beat the mercs and the Ferraris in race, long time before Lotus brought the LWB car.
And he said in Monza, where the LWB package wasnt complete yet, that he doesnt feel any difference compared to the SWB. But in Japan, he said the car was much better.

And if Kimi doesnt like the LWB car, that's partly his fault: he doesnt work in the simulator and the LWB was created and devlopped in the simulator with Grosjean and Prost and maybe an other test driver.

According to Boullier (after FP1), today they tested some stuff including suspension parts.

I doubt if Kimi even train the course in the simulator like other drivers do, I wonder if he rely only on his talent, if he does not train then he is very very good (which is no doubt at all)...

about the suspension updates, so that means Lotus is really on a charge now for this 2nd place in the championship, today's practices showed that Redbull may not have that much of advantage like it was on previous races... Kimi was quite competitive with "older" car, so I'm expecting Grosjean to be even faster.
I hope this race won't be bored like previous ones @ redbull dominance :evil:
