A testing update. They seem to be making good progress. Hope the car has some pace.

"A new aero package" I don't know what would they be changing this time,. maybe the rear of the car.

Akrapovic · 21 Dec 2017, 12:47 (Ref:3788521)

Compared to last season, it appears to have-

Slightly reprofiled nose
Inboard winglets have gone (probably low drag testing, but there may be some funky new aero going on there)
New dive planes
Squared off arches
Mirrors moulded into the bodywork
Air intake in front of the cockpit is gone
Rear arch holes are now inboard
New headlight shape

Looks like they raided the Porsche parts bin for those headlights...

TF110 · 21 Dec 2017, 16:34 (Ref:3788576)

These aero changes aren't even what the car will have, apparently. They will change again next year so obviously they feel there's still gains to be made, which is good!

I was thinking about how clm started 2016 season like an audi r18 chinese copycat and now taking ever more "ispiration" from last season porsche

I wonder if they've had the opportunity to put it in a wind tunnel to aid these aero updates or if they're still relying on CFD.

Who's windtunnel would they use? Who does Kolles have connections to that would have one on demand?

Ospi · 22 Dec 2017, 06:42 (Ref:3788649)

There's a few in the UK I thought, though likely not full scale things.

**Adam43** · 22 Dec 2017, 15:58 (Ref:3788715)

When in F1 Kolles involvement with Hispania and F1 they used the wind tunnel at Mercedes and Brackley. I don’t think they’ll have been using that recently

Last Test done for 2017! Looking forward now to having some days off and enjoy some time with my family. Merry Christmas

It looks like they upgraded the steering wheel since 2015

I beg a pardon if this was mentioned somewhere above, but was there any info about new turbo layout at Nissan-Cosworth V6? It's not on the block (or is it?), so the pipes length is different - how does it affect hp and moment specs?

chernaudi · 26 Dec 2017, 21:40 (Ref:3789232)

Should be alongside the block as on a conventional V engine. The Toyota has a similar layout.

helgi · 27 Dec 2017, 06:32 (Ref:3789259)

I've found it in the Web googling most of the evening.
The layout is different (at least I think so). I wonder what was the amount of work needed to construct new inlet and outlet pipes - so they could not just use spare parts left after 2015. While it was NISMO who supplied engine, I think there are no problems with power or torque.

Damian Baldi · 27 Dec 2017, 11:56 (Ref:3789308)

This is the car from 2015. The turbos are in the same place (in a different angle), but the air inlet, the exhaust exit, the intercoolers, and the cooling on the sidepods are different.

From 2016 to 2017 the rear of the car changed three times. Now there is more room for the air to go to the rear wing, and exhaust exit and cooling are different.
