Lightest Car for each concept

[TommKG]

Hey,

I just read Claude's answer to a weight question (he wrote in the FSG forum that 180-200kg for a 4 cylinder and 130-150kg for a single would be an appropiate design goal).

And now I'm asking which are the lightest cars for each concept?

I mean:

- single 10inch
- single 13inch
- two cylinder (I don't know if there are a lot of these running) 10/13
- 4 cylinder 10/13 (I only know Ann Arbor with 10inch..)

- Electric 10/13

I know that Delft had super leightweight car some years ago, would this be still "legal"? So that should be the lightest so far.


Would be great to have a list here.

Cheers,

Tom

For the electric cars:

Delft's 2011 car should be the lightest 10" car with 178kg.

Zurich's 2011 car had 181kg in Silverstone with 13". (It's now little bit heavier though )

I'm not so sure for the combustion cars. TU Graz seems always pretty light with their 13", 4 cylinder.

include drive??

I'm not so sure what you mean with "include drive".

(If you mean "driver". Then no, of course not).


Both weights are the official race weights from FS Silverstone 2011. Without driver but ready to race.

Delft and Penn State were both under 300 lbs in the past few years with their singles. Delft has since been electrified and Penn State went turbo last year, which added weight. GFR was 304 at Michigan this year without aero, I think 350 with. Oklahoma was 331 with an Ape and full active aero (somehow).

For cars on 13's I've heard that someone was low 350's a few years ago, and this past year we had a 360 lb car from Kettering out in Cali.

And I've seen a couple 4 cyls either very close to or under the 400 lb mark.

Yes, these are all without driver.

Oklahoma was very light with their space frame, aero car with 10's
Missouri S&T has been below 420 lbs with a space frame, 13's, aero and a 4 cylinder
SDSM&T was 370 lbs with a space frame, 13's, aero and Ape

Once we have established the lightest car for each concept, it will be interesting to review how each of them went at comp. Especially the Endurance event.

[Rex Chan]

What would be more interesting would be a program that plots results (design, autoX, enduro, fuel) vs weight, for ALL teams, so we can see if there is a trend.

[Will M]

Building the model would be quite easy if that info was included with the official scores. Weight, wheel size, engine size and type, NA vs Turbo vs Superchager, fuel type, and chassis type could all be added.

Wollongong were 188kg (414lb) in 2008 with a spaceframe turbo intercooled 4, on 13's.

That car died in the enduro's due to lack of carbon glueing knowledge.

The following year was 198kg with similar specs to above and we placed 3rd in enduro and overall.
