On the surface, carbon fiber sounds like a wonder-product which can replace much of the heavy metal, especially steel, that makes up the vast majority of nearly every automobile's structure. Dig a bit deeper, however, and there are a few flies in CF's ointment that make it very difficult to use in vehicles: price, supply and the time it takes to mold a the weaved material. Japan's big three carbon fiber producers are tackling each of these issues in a number of ways. First, the price of CF is expected to become more competitive as both carbon cloth goes down and rolled sheet steel goes up. What's more, as additional CF producing plants come online in the coming years, both the price and availability should improve. Third, new molding processes are being developed which could reduce the time it takes to produce a CF part from hours to minutes.

Carbon fiber is expected to ease the transition to more fuel efficient vehicles as it weights a fifth of what steel does for a part of roughly the same strength. As Automotive News points out, the overall weight of any given vehicle could be halved by replacing major structural steel components with CF, so expect to see CF move down market from the exotics to more mainstream models in the next decade or so.

It's the mayor of London in one corner and Porsche, the maker of thoroughbred sports cars, in the other.

In the green trunks, Mayor Ken Livingstone has decreed that a $50 daily tax shall be levied against all gas-guzzling, emission-spewing vehicles that drive through his city beginning in October. His logic says that it will fight global warming, and the money raised will help implement a Paris-style bicycle plan for the city. Re-election is around the corner, so this initiative is imperative to his tenure.

In the black trunks, Andy Goss, the Managing Director of Porsche Cars GB, rejects the tax as unjust. The automaker claims it is a disproportionate fee that will have a very limited effect on CO2 emissions. Its plan is to write Livingstone a letter requesting that he reconsider the proposal, and if nothing happens after 14 days, take the matter to the courts, which could throw out Livingstone's tax altogether.

And the winner is... neither side. Both are unable to deliver a knock out punch, so the winner will likely be chosen by decision.

How do you top a car like the Lamborghini Murcielago Roadster? It's simply one of the most desirable supercars on the market. But while the terms "practicality" and "Lamborghini" don't belong anywhere in the same sentence, the topless Raging Bull's roof is something best considered only for emergencies – just when the contraption's complicated installment procedures prove most frustrating (or so we hear).

Coming to the rescue are the American coachbuilders at Genaddi, who've designed a special roof for the special supercar. If the name rings any bells, Genaddi is responsible for such intriguing open-air conversions as the Corvette LSR Roadster, Maybach 62 cabriolet and the (limited) production version of the Ford GTX1 concept.

Genaddi's design for the Murcielago is far less complicated, but from the description, its simplicity could be its most redeeming quality. Made of carbon fiber, the six panels are designed to fit under the front hood of the roadster so it can be taken along with the car. They can be mounted in different configurations – completely open, completely closed, T-top or targa – and include a rear glass window. Genaddi expects to put the roof into production in May, when it will sell for $26,000.

Yes, that's enough to buy a decent complete car, but it's a small price to pay if it means getting more use out of your Lamborghini. And that's a worthy cause which we here at Autoblog support whole-heartedly.

British buyers have been able to glance quickly at their color coded environmental labels since 2005, a convenient way to assess the footprint they'll be leaving on things green or furry. Now buyers can head to the Department for Transport's website, and the DfT's ACT on CO2 program will provide a list of the top 10 cars in 14 different categories for low CO2 emissions. Providing this information in an accessible manner has the potential to spur drivers to purchase more fuel-efficient (and thus more CO2 efficient) vehicles. The categories were laid out by What Car? and the rankings were created using data from the Vehicle Certification Agency, which conducts the official emissions tests for the DfT. The website can be found here.

Volkswagen has been down this road before with the Jetta Trek back in the late '90s. This time, though, they're putting a green spin on it. Lime, to be exact. Chi-town Volkswagen dealers are giving buyers a bicycle and roof rack for the next month. The premise is that the dealer will encourage you to take your bike on quick, short-distance jaunts. Not driving a car at all by riding a bike is super effective at reducing fuel consumption, gridlock, and CO2 emissions. Biking is also way cheaper than exotic technological solutions; plus, you'll get some exercise, which is hard to come by in stop and go traffic. The cycle is still a Trek, dubbed the Lime, which is one of their newest models and has a three speed automatic transmission that automatically changes gears for you, in the hopes that you'll find it a more enjoyable way to ride. We'd probably hate it. It really is a great, simple solution that could work for a lot of folks. We know this is Autoblog, and this has turned into a bicycular love-fest, but we have to applaud the marketing stunt as an elegant (if gimmicky) way of focusing on our vast appetite for fuel.

It ain't over till the fat lady sings, and although it promises to be a real screamer, TVR's seductress is anything but fat. We were pleased to bring you earlier information on the upcoming Typhoon, and now more details and computer-generated preview images have surfaced.

Once it hits production, the Typhoon will be TVR's first completely computer-designed car, helping the automaker fine-tune the aerodynamics to a more efficient extent. Power will come from TVR's 4-liter inline-six, only with a big nasty supercharger pumping horsepower up to 600 and torque up to 500 lb-ft. Supercharger or no supercharger, six hundred horses out of a six-cylinder engine is no mean feat, and the engine specialists at Ricardo helped along the way.

Follow the jump for the rest of the story and some additional renderings of the Typhoon.

Last December, Ascari announced it was producing a new track-ready model more hard-core than its already quick KZ1. Now the British sportscar manufacturer of the KZ1 is ready to take the wraps off its new supercar in just a few days at the 2006 MPH show in England, and is giving us a sneak peek at its new crown jewel.

Unlike the FXX, which, technically at least, is a track-only car and not certified for road use (the Ferrari doesn't even have side-view mirrors), the A10 is road legal, though we suspect the ground-scraping ultra-low ride height and the race-spec suspension will mean it's more suitable for the track. The new Ascari is also a great deal less expensive than the FXX – about a third the price, actually: the FXX costs about €1.5 million, and the A10 costs "just" €522k. (Though, to be fair, the FXX price incorporates participation in a development program and includes storage, transportation, and upgrades to the equipment as they're developed.) Only ten of the super-quick Ascaris will be built to order for fortunate customers, who can also specify electronic "luxuries" like power windows, locks and mirrors, climate control and alarm system.

Now for the good stuff: the new Ascari ups the power from its 5-liter V8 from about 500 in the KZ1 to 625 horsepower in the A10. With carbon fiber body panels, the car weighs just 1200kg and is said to be capable of hitting 60 mph in 2.8 seconds and 100 in under 6. Those are some impressive claims, but with that much power and such low weight...well, let's just say we're dying to see it in action.

In a new entry over at TheTruthAboutCars.com, writer Johnny Lieberman trips the rant fantastic, lambasting carbon fiber-- material of choice for racer and poseur alike. So, what does the writer have against the sought-after weave? Well, it's impact properties, for one (Lieb' recons its accident constitution is a one-and-done proposition), and its indulgent cost for another.
Granted, Lieberman doesn't spill his vitriol on the carbon fiber's motorsports applications, he mainly calls to task the trend where the shiny plaits (or knockoffs thereof) are employed in everything from dashboard appliqués to parking brake handles, the vast majority of which offer few tangible benefits in production cars beyond aesthetics.

What do you think... is carbon fiber over-hyped, or does it remain a desirable material?
