And now: The Carbon Fiber Car

No joke:

Nice to see that maybe at some point car makers will think about mechanical efficiency, just like cyclists. . . especially at 100mpg.

I always wondered why they never thought of that before.

I saw a carbon hood once and other carbon parts, but not a lot.

uhh...
i guess you guys aren't real familiar with the (auto)racing world. champcars, F1, and now even LM/LMP sportscars have all been made of carbon fiber for 20 years.

Oh good god! What an ugly car...

Anyway, before anyone starts nitpicking this guy, the car has a structure and space frame made of carbon fiber in addition to the body.
Most high end sports cars have bodies and various parts made of carbon but not the frame. It's one thing to make a couple of cheap tubes out of carbon fiber or a thin sheet out of many layers, it's another thing to get a frame several inches thick made of carbon fiber.

I can just hear the conversation in my household now.

my wife: "hunny, I have some bad news"
me: "good God!! ... you're pregnant again ... are you?
my wife: "heavens no, it's about the car"
me: "you mean our fuel-efficient, carbon fiber marvel?" (obviously showing intense pride)
my wife: "Well, I had a little accident in the Wegmans parking lot this afternoon. According to our mechanic, there's good news and bad news. The good news is that the damage was minor and we only have to replace the front right quarter panel."
me: " ... and the bad news?
my wife: "the bad news is that it's gonna cost our insurance company $15,000 to replace the panel and they're already decided to drop us as customers"
me: "not to worry hunny. Just think about how much we saved on fuel costs over the past six months we've owned the car. It's a wash"

sheesh! Thus ends another episode of "As the wheel of useless technology turns."

Yeah, well, I like the fact that I can take a hammer to any screwed up body panels rather than having them shatter or otherwise totally fail. That and buying used.

However, I like cycling more.

I think you are missing an important point: If auto manufactures start using CF parts in production cars, you can expect to see much cheaper CF parts for our bikes.

Also, while it is nice to be able to bang out a ding, when you do buy a used CF car, you can bet it will have a new critical part such as a crumple zone (more like shatter zone in CF, but designed to absorb tremendous energy) while a used car might easily have a cheaply repaired crumple zone. Not to mention how metal can twist, bend and disform, putting wheel alignment out, while CF will either be perfect or completely broken
And a frame made of CF wouldn't be several inches thick, but more likely of sandwich type construction, super light, honeycomb material.

As Doghair mentioned, this is all tried and tested on the racetrack, and if you see a racecar wipe out at 200mph, it looks pretty similar weather they are CF or alu/metal. I'd vager the driver would rather be in CF where there is less weight and momentum to mess him up.

Imagine if traffic were made up of mostly sub 1 ton vehicles having their regular accidents with much less momentum for the same speed. Anyone here knowledgeable about if this translates to less injuries for passengers or is it the same as they are going from 40-50 mph to 0 mph in nothing flat?

CF is labor intensive, good luck getting cheaper CF parts for bikes.

CF is a bad choice for cars due to price. Even aluminum is too expensive to be used extensively on most cars (think NSX, Ferraris, a high end Audi or two, etc).

Bugatti has a lot of CF in it, it's been around for years. Of course, last I knew they didn't import it, and it cost several hundred thousand... On the good news side, PJ O'Rourke declared it's existence full justification of western civilisation.

That fiberglass they use for bumpers pretty much disintegrates upon impact. for that matter, if the car doesn't give in a crash, you've got a much better shot at waking up dead.

Carbon fiber isn't so expensive solely due to supply and demand. It's a very expensive material to work with. Note that the only cars )outside of this uber green friendly model) that have been mentioned are exotics. We're finally seeing aluminum used more in at least parts of the body of cars at and under $30k (US). Carbon's a long way off for the everyday driver. Unless, of course, they put on a carbon hood or trunk or something like that.

Doesn't anyone here realize that your mclarens, pagani's, and such have frames made of metal. The only major component that is CF is the body and various bits and pieces like the clutch, disc, etc. The structure, bulkheads, etc, are made of... TADA! ALUMINIUM like my $289 mountain bike.

The engine bay is lined with gold though...



I for one, welcome our all carbon fiber automobile overlords...

You can find street legal cars that use carbon in the tubs, like the Carrera GT and Enzo.

Easy trick:
Get old cast iron tub, layer wax paper down, order several rolls of carbon fiber from mcmaster, get cold set carbon epoxy. Put down 4-5 layers, let set, remove from tub, glue some legs on, put several layers of lacquer on, polish, glue some black rubber daisies to prevent slippage. Voila! Carbon fiber tub!

Really, do you have anything from the manufacturer showing what the structure's made of?
The McLaren F1 uses aluminium for most of the bulkheads and frame. The body's a honey comb carbon/aluminium matrix.
