Ford seeks to lighten cars, improve mpg, with carbon fiber

This is a very good thing.
Not necessairly for me yet, as I probably won't ever own a Ford, but if Ford can mainstream CF and bring proven production costs down, everybody'll be doing it. Good stuff. |

I'd rock the living jesus out of a 2,200 pound Focus. They handle incredibly as they are.

I think a 2,200 pound Focus ST would be a rather fun car. But, I'd love to see this applied to a WRX.

I bet they have trouble meeting crash safety standards when they do this. Think will also add $$$ to cost.

But really, I'd like to see Ford do that to the Mustang. A sub 3,000 pound modern Mustang would be killer. |

Just a point of reference, driven a Thunder Roadster that was a blast. Despite only having 120 HP, it does 0-60 in about 3.5/4 seconds and can pull 1.5 G's. That's what 1200 lbs will do for you.

How about ford's new fiesta st that is coming out? A carbon roof, hood and quarter panels aren't terribly complicated shapes and pretty flat too. It would further drop the center of gravity down and lighten an already light car.

Yeah, but you could do that with just aluminum. CF is supposed to end up cheaper than Al. That is why they keep wasting/spending money on it. Its the next big thing. But aluminum is already the current thing that we can easily do.

aluminum(and cf) is still WAY more $$$ than steel and there really isnt any advantage of using cf over aluminum in low end cars and there wont ever be, i think |

The reason they stay away from plastics, and are leaning towards carbon fiber, is due to the tolerances of the plastics, resulting in body gaps.
The Corvette's fiberglass does well. But the plastic used for Saturns was prone to expansion/contraction, created huge gaps in the body panels, and resulted in a very unpleasing look. From what I remember. |

The weight savings isn't there with plastics like it is with CF, fiberglass and aluminum. They have to make plastic panels pretty thick to be rigid enough to span large sections. That's where CF & FG rule. Paint never held up well on plastic. Most Saturns look like hell after just a short time. Paint coming off in sheets. A shame, as plastic could be very cost-effective. Probably not the greenest option though.

That is a curious thought. Would plastics save weight over steel enough to save the petroleum used to make them? Cars are recycled very fully so the steel or aluminum is recovered. CF would probably not be.

Also, as previously stated, plastic expands and contracts a lot more than steel (like 10x) with temperature, so the panel gaps have to be made larger. |

I believe the E92 3 series (coupe) has composite front fenders, the sedan may as well. I'm not talking M3 here, but the 328 & 335. RTM with fiber reinforcement if my 10 second look at one in a body shop was accurate. The M3 coupe of course has a carbon roof.
Anybody know if the F30 retained the composite fenders? |
