Michael Royce made it clear at MIS the templates will be included in the new rules due out soon. There is at least one small change which is a 50mm wide slot half way down the centre of the foot box template to allow it to pass steering coloums easy during tech

so the new Y-template would look something like this?

Our frame team didn't realize the pages 104+ so our frame has to be significantly altered :/

i asked for clarification on bearings etc.

here is the response i got:
"Dear Jeremy,

Any bearings, bushing, column brackets, column supports, UJ’s, etc. will have to fit within the 50 mm wide slot or the 50 mm radius cut-outs (there will be one at the bottom as well as at the top of Template “Y”).

If the structure is less than 50 mm wide and on center, it will pass.

Basically, we will modify the template as noted above, and then this revised template has to pass past everything except the steering wheel and any padding required by Rule 3.4.14.

We hope this explains things."

so it will look like yours frenzy but with the cutouts and slot top and bottom

but if the slot goes all the way through the template..then we have like 2 templates with no connection in the middle?

I asked for a rules clarification on the new fuel economy rules and the cut-and-pasted text below highlights the important parts. It seems that the 29L instead of 26L/100km was a mistake - the 26L value stays in the formula. They said the 2009 rules should be up in a few days. Enjoy!

8.22.1 If Vyour is less than Vmax then the following equation will be used to determine the fuel economy score:

FUEL ECONOMY SCORE =

If Vyour is greater then Vmax then the following equation will be used to determine a negative fuel economy score.
FUEL ECONOMY SCORE = -

Where:
Vmax is the volume of fuel that produces a fuel consumption of 26 liters/ 100 km. Note - For an Endurance Event distance of exactly 22 km, Vmax is 5.72 liters (1.51 US gallons).”
Vmin is the smallest volume of fuel used by any competitor
Vyour is the volume of fuel used by the team being scored

8.22.2 Vehicles using a fuel volume which exceeds Vmax by 33% will score negative one hundred (-100) points.

8.22.5 Fuel economy scores can range from negative one hundred (-100) to positive one hundred (100) points.

I guess that didn't work. Lets try again:

8.22.1 If Vyour is less than Vmax then the following equation will be used to determine the fuel economy score:

FUEL ECONOMY SCORE = 100 X ([(Vmax/Vyour)-1]/[(Vmax/Vmin)-1])

If Vyour is greater then Vmax then the following equation will be used to determine a negative fuel economy score.

FUEL ECONOMY SCORE = -100 X ([(Vyour/Vmax)-1]/0.33)^1.5

Sorry about that.

2009 rules are out

Just had a quick scan...no real shockers is there? Apart from the cost report of course...oh and fuel economy...but we've known about those for a while.

Whats with this incomplete cost website? You wouldn't start serving coffee in a coffee shop while the walls are still being erected. Websites are no different. I'm a little afraid of whats to come.

Hi guys... I am member of a team from India.Just need a clarification.In new rules for impact attenuator, it states:
"The team must submit test data to show that their Impact Attenuator, when mounted on the
front of a vehicle with a total mass of 300 kgs (661 lbs) and run into a solid, non-yielding
impact barrier with a velocity of impact of 7.0 metres/second (23.0 ft/sec), would give an
average deceleration of the vehicle not to exceed 20 g’s, with a peak deceleration less than or equal to 40 g’s"

Does it mean that we have to attach our IA to original chasis?? or drop test data are sufficient??

No. You just need to attach a 300kg weight to the IA for the test.
