Lotus E21 Renault

I've heard the the FIA wanted Lotus to try them for visibility purposes during the race, so Lotus had no choice in running them. Whether they have them after the summer break is a different matter, but I doubt they will be the best choice aerodynamically, even if the article in the homepage says so.

That would be far too magnanimous by Lotus to test them in the race for FIA, and I'm not sure FIA are able to pick just one team like that and force them to, so there should be an advantage Lotus see...

well we had the FIA linked earlier this weekend in the thread.

If they're on after the summer break then we will know... It's an interesting development if it is of Lotus's own doing, very rare to see the mirror housing itself get attention. More often the mirror stalks that are changed but I suppose every team is looking at the very fine details now.

Guys, what's the difference between new and old exhaust???

It is something they can use next year. I doubt it'll bring anything significant, but if they find 20-30 of such little things it does add up.

This was what i heard as well. Testing for 2014,

the article says that they had to do two crashtests.

does anybody know, if they can use both type of chassis in one race e.g. RAI the new one and GRO the old one?
do they need another crashtest if they revert to the old chassis...but IMO this doesn't make any sense.

not that i aware of.

They would swap in btw races like singapore and suzuka. Shorter wb would be use in narrow street races while the longer one on wider circuit. It reminds me of F2007 that suffer on narrow circuit as ferrari opted for longer wheelbase.

The article says that if they opt for that solution the would have to pass a crash test, not that they already had. I don't know about this, a longer wheelbase means a new (longer) chassis and a new chassis means a pretty much new car with different aero, mechanical benaviour, etc.

A longer wheel doesn't necessarily mean a new chassis. You only need to change the wishbones to sweep forward or back a little bit more. I believe this is what Mercedes did a coule of years ago when they lengthened their wheelbase mid season.

the article says (in translated garbled English):

A longer wheelbase means longer nose
Lotus has yet a further coup in the hindquarters. The wheelbase of the E21 should be extended to ten centimeters. And (meant is at the front) front. Because is it pushes forward the front axle by a different angle of the Wishbone, Lotus needs also a new, longer nose. Thus, the distance between the front wing and front tyre is maintained. This procedure requires two new crash tests. The dynamic front from the front and the so-called go from test side. While a hydraulic punch presses with a force of 4,000 Newton from the side towards the nose to determine at what strength she cancels. The nose must withstand over 30 seconds to a weight of 400 kg without any structural damage occur.

so new crash tests only for the nose
