All these guys need to do next is to figure out a mod that'll knock about 50 HP off the Elise once they've made it heavier with their carbon fiber, and they can win some kind of aftermarket Darwin Award.

@firemunkie: no not carbon, composit. Composit is moulded plastic, and can be made incredibly thin and light, the carbon fiber being woven will be more dense and thicker becoming heavyer than the composit panels that it replaced.
Carbon fiber will be far stronger but it isn't the lightest material around. #seibon
This is the latest stupid fad in the automotive world: carbon fiber everything. Like it's some sort of panacea. And I'm sure automakers and especially aftermarket companies are fully aware that consumers are suckers for this stuff. I'm sure that in many of these applications there are other, far more appropriate materials. #seibon
I would love to go back in time to when the creators weighed the cars. As soon as they're faces went 'wtf?!' I would laugh, slap them in the face and enter a portal. #seibon
@KeyserSoze: hah, I think he should stand at their SEMA booth with that expression every day, never moving. whenever he looks up at the cars, he just cries even more. #seibon
Am I the only one who wants to shake his cane in the air at these youngsters who forget about Fiberglass? Seems like Carbon Fiber is a spoiled hipster punk who put it's grandpa in a resting home. I think it's time he busted out of there and got some new rainbow suspenders and hit the town. #seibon
@FrankGrimes: I never saw any fiberglass need an autoclave. You can't build a carbon fiber anything while drunk in your garage and getting high as a kite on fumes. Those darn whippersnappers with their fancy furnaces and expensive materials. BIG DADDY ROTH NEVER NEEDED CARBON FIBER! #seibon
@Ben Wojdyla: It all depends on the kind of resin you use. Some cure at room temperature, others require high temperatures. And, regardless of the fibers used, the pressure in an autoclave will help reduce air bubbles in the finished piece, improving strength. #seibon
Seriously, though, CF is only lighter when it's used for structural pieces designed by an actual engineer, not a guy making molds for a "tuner parts" company.
This is a common thing: aftermarket CF hoods, fenders, and whatnot are almost always at least as heavy as the steel they replace; if they weren't, they'd be fairly flimsy. #seibon
@Paul Y. don't drive too fast.: ...and the other thing: the fortwo's body panels are all plastic (ABS, I think). How on earth could CF be lighter? Besides, one who buys a smart does so for the potential to be an obnoxious ricer. They do so for the opportunity to drive The Nerdiest Car In North America. #seibon
I once weighed some super expensive high end carbon fiber replacement body parts for a previous generation STI that a friend of mine bought (Hood, Trunk, front fascia, and fenders) And I found that all those Carbon fiber parts actually added 45lbs. Needless to say he was dumbfounded since he is of the thinking those parts would lighten his STI by a million pounds. I blame the extra reinforcement needed to make the carbon fiber tough enough for the street. #seibon
A carbon fiber Elise would be incredibly kick ass if they actually did it right, but that would require replacing the actual structure of the car (not just the skin) with the stuff. But, god damn... do that to an Exige 260? Holy bejeezus, that thing would be crazy. #seibon
@gallahad: Replacing an extruded aluminium and bonded chassis with carbon fiber doesn't seem possible. I think all carbon fiber cars (McLaren F1, Porsche Carrera GT, new McLaren MP4-12C, and ???) are monocoque construction rather than a frame made of CFRP with panels on top.
By the way you can already get a Lotus Elise variant with all carbon fiber panels that are lighter than the original fiberglass; it's called the Tesla Roadster. But it comes with 900 lbs of batteries ;-). The Tesla Roadster is still the cheapest car with all carbon-fiber body panels. #seibon
@skierpage: Hey, stop stomping on my dreams with your science and logic. This is America, damnit.
And meh to the Roadster. The Model S is going to be hot, but the Roadster's just boring. They took all the crazy out of the Elise's design, which is no fun. #seibon
@I was drivin' that Model A: I was talking to one of Seibon's staff (I was curious if the carbon fiber made the Elise any lighter) - his explanation was that the CF Elise (and I suppose also the Smart) were merely done to show what the company was capable of doing, rather than for any real performance benefit. At least they're not charging $400,000 for their experiment (unlike Lexus). #seibon
maybe they should focus on carbon fiber decals for body panels. That way you could get all the benefits of carbon fiber? without all the extra weight and expense.

Carbon Fibre on a car not worthy - fail
heavier than steel version - fail #seibon

How's FAIL²? #seibon
11/05/09
the smart's body panels are all light-weight plastic, not steel. so it's not really a surprise that the carbon fiber panels are heavier.
your post - fail. #seibon
11/05/09
Then this is an even larger FAIL. Replacing something light with something heavy, for purely cosmetic reasons.
While I was incorrect in material replaced, my logic is still unassailable.
Hence, your argument = FAIL #seibon
