Good pic, I was going to start a thread this morning.

 

I can see a few of those wide front wings being damaged, it will be interesting to see if the changes to the front and rear wings will increase overtaking.

 

Mclaren unveil their car on Friday.

Apart from the mirrors!

 

The aerodynamic aids were banned because they hid the sponsors' logos.

 

Errr No.

 

The aero appendages are removed to reduce downforce.

 

The Aero revisions for this year are;

Narrow High rear wing to reduce rear downforce and narrow the wake left behind it.

Wide low front wing, less losses in corners when following another car.

More effective rear diffuser, lower and wider.

SLICK TYRES!! Mechanical grip replaces aero grip.

No aero appendages on the main bodywork. Reduce wake, turbulance and downforce.

Bargeboards, minimised to again reduce downforce.

Those rear wings are hideous aren't they?

 

I'm interested to see how KERS affects the sport. And if BMW have fixed theirs to stop it shocking the pit crew :D

 

Torro Rosso's had it's lineup fully confirmed, now just waiting to see if Honda are bought by Prodrive or anyone else.

Not quite sure on the "more effective" rear diffuser. Sure it's wider but don't underestimate the effect of the height reduction and the lack of an effective RCD.

 

Also don't forget that the driver now has control of the front wing flap angle. Will be interesting to see the FWF's backing off coming onto the main straight and then ramping back up coming into the first corner and infields.

You think that's ugly... watch this space....

:(

Ooh I didn't know that.

 

Probably as soon as he's hidden all the sharp and painful things from Mrs. Chris. :D

:D

2009 season changes

 

A number of changes to both the Sporting and Technical Regulations have been made by the FIA for the 2009 Formula One season. In the case of the Sporting Regulations, the primary aims are increased reliability and further cost reductions. In the case of the technical changes, there are three main objectives - reducing the role of aerodynamics in the cars’ performance; making overtaking easier; and keeping lap times in check.

 

Tyres

After 10 seasons on grooved tyres, Formula One racing returns to slicks in 2009, as part of moves to increase the emphasis on mechanical rather than aerodynamic grip. With no grooves, grip will increase by around 20 percent, bringing a significant performance gain. However, that gain will be offset by the vastly reduced downforce levels of the revised aerodynamic regulations (see below). The overall effect should be reduced performance through high-speed corners. Drivers will still have the choice of two dry tyre compounds and will still have to use both compounds during a race.

 

Kinetic Energy Recovery Systems (KERS)

From 2009 teams have the option of employing a KERS to boost their car’s performance. As its name implies, a KERS recovers the (normally wasted) kinetic energy generated by the car’s braking process. This energy is stored using a mechanical flywheel or an electrical battery and then made available to the driver, in set amounts per lap, via a ‘boost button’ on the steering wheel. Under the current regulations the power gain equates to around 80 horsepower, available for just under seven seconds per lap. This could be worth several tenths of a second in terms of lap time, but the weight and packaging of the system - and its impact on the car’s weight distribution - also have to be taken into account.

 

Engines

In a move designed to boost reliability still further, rev limits will be cut from 19,000 to 18,000 rpm and drivers must now use the same engine for three, rather than two, consecutive events. Teams will be limited to eight engines per season - eight for each race driver and an additional four for testing. Just one team - Renault - has been allowed to make performance modifications to their engine for 2009 in order to help equalise power outputs.

 

Aerodynamics

Along with slick tyres, this is the biggest area of change for 2009. Downforce will be dramatically reduced and the cars’ bodywork will appear much cleaner, thanks to new dimensional regulations that effectively outlaw extraneous items such as barge boards, winglets, turning vanes and chimneys.

 

As well as reducing overall aero performance, the revisions are also designed to increase overtaking by making the car less susceptible to turbulence when closely following another driver. The most obvious changes are to the front and rear wings.

 

The front wing becomes lower (75mm from 150mm) and wider (up from 1400 to 1800mm - the same width as the car) with driver-adjustable flaps. Drivers will be allowed to make two wing adjustments per lap, altering the wing angle over a six-degree range.

 

The rear wing becomes taller (up 150mm to bring it level with the top of the engine cover) and narrower (750mm from 1000mm).

 

Also at the back of the car, the diffuser has been moved rearwards, its leading edge now level with (rather than ahead of) the rear-wheel axle line. In addition, the diffuser has been made longer and higher, all changes that will reduce its ability to generate downforce.

 

Testing

From 2009 onwards testing is not allowed during the race season.

The first picture really does make it look massive. I saw some footage earlier of the ferarri going through some press laps and it didn't look bad at all. Nice to see a move away from random bits and bobs on the sides of the cars.

 

Question: will this move away from aerodynamic appendages help the smaller teams ?
