McLaren MP4-29 Mercedes

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.

Well, everyone is leaving exhaust out of the equation. Suspension in question is placed behind the exhaust, so the air that it effects will mingle with exhaust gasses. It may even produce some upwash, that can be quite beneficial in high speed corners.

Another small beamwing below as well.

Scarbs posted this snippet in the "legality" thread - I thought it would be of interest over here as well...

It's interesting to see gold foil and temperature sensors on the floor. How on earth is any hot air getting down there?

I didn't realise the McLaren rear wing end plate stops half way down on the leading edge. Has it been like this all week to accommodate the lower wishbones? Why doesn't every other team have endplates like this as surely this will reduce drag?

This picture of the mp4-28, shows how the end plate curves in then back out again at the bottom of the leading edge. Why does every other team have this? Why not just have nothing there to reduce drag?

Maybe they want to see if there is "leakage" of hot air coming out of the cooling outlet under the "butterfly"

It is actually connected to one of the extensions right at the back of the wing.

AMuS talked to Newey again about the suspension...

http://www.auto-motor-und-sport.de/form ... 17312.html

One of the points he brings up is that the added drag will increase fuel consumption, which is critical this year. Says that they may well be shooting themselves in the foot.

It's a valid criticism. I think this lends more support to the idea that we'll see different shrouds at different races. Of course, that depends on exactly how much extra drag there really is. I'm reminded of this experiment from Mythbusters...
If you drive a pickup, common sense might lead you to think that opening the tailgate on the road is the more fuel efficient way to go. In fact, the idea that tailgates block airflow and increase drag became widely circulated, and some truck owners intentionally drive with the tailgates down to ease up on gas consumption.

But when MythBusters Jamie Hyneman and Adam Savage drove identical trucks under the same conditions across the desert — one with the tailgate up and the other with it down — Jamie's tailgate-closed pickup outlasted Adam's by more than 30 miles (48 kilometers).

Closing the tailgate actually improves fuel efficiency because it creates a type of airflow called a separated bubble within the bed of the truck. As wind rushes over the moving truck, that bubble of slow-moving air deflects it over the raised tailgate. By guiding surrounding air over and across the bed of the truck, that vortex effect prevents added drag.
Of course, the aero isn't exactly the same, but the suspension should be creating a similar "bubble" in front. Which goes back to my thought that it's what happens behind that really matters.

Sorry if this is a stupid question which has already been covered, but where's the starter motor hole on this car? Is that somewhere else entirely on the 2014 formula cars, or does the MGU now serve this function?
This year it is covered by a flap in all cars. If you look closely at the pic, you can see it in the middle of the lower central zone of diffuser.
Aha! Thanks very much.

It's not the bubble in front that will create the drag, it's the low pressure behind.

These new rear suspension remind me the Lancia 037 huge vertical spoiler.
In this case I suppose that it creates a high pressure on the upper side of the diffuser and, moreover, the after body recirculating flow is used to "call" much more air from beneath the car "transforming" the drag in down-force.
Very clever!

Like the guy martin cycling speed record with the truck in front if him.
