Behind the wheel of the Caparo T1

Although we've covered the entire gestation of the Caparo T1, we've yet to drive it. No surprise, as we'll be the first to admit that it outclasses us in every conceivable way. On the other hand, Nick Hall, the supercar scribe from across the pond, is one of the few motoring journos that actually has had seat time in the clichéd "Formula One car for the road." And although he hates that description, if the shoe fits...

His review over at World Car Fans provides you the prerequisite stats for you to rattle off when you're bench-racing your buddies, and the description of his time behind the wheel gives the best insight yet on what the 1,045 BHP per ton track toy is capable of – and why even though it's road legal, your kidneys will thank you if you avoid trips to the corner store. Read on and enjoy.

Enter the rumormill: McLaren F2 under development, again

There's this thing about sequels – they normally suck. And this time of year the suck surrounds us. Autocar decided to add to the detritus by reviving the return of the McLaren F1 legend in the form of the F2.

The information surrounding the new supercar is sound, considering that Mercedes originally tapped the engineering firm in 2004 to produce a less expensive alternative to the SLR. The mid-engine prototype – codenamed the P8 – was put on hiatus after some financial and quality woes hampered Mercedes' forward momentum, combined with the less-than-stellar reception of the P8's big brother. In short, Mercedes was pissed and didn't want to explore future projects with McLaren.

Although we've always taken Autocar's pontifications about as seriously as our local read through the supermarket tabloids, they claim to have sources within McLaren that says the F2 has been testing around the company's Woking headquarters, wearing Ferrari 360 bodywork. Time will tell, but in the meantime, watch out for Batboy.

Video: Live from Dearborn - 2008 Mustang Shelby GT convertible

I admit it, I'm an unabashed Mustang fan. I have been ever since I was a kid and a family friend had a blue '69 Mach1. The first brand new car I bought after I graduated from college was a '91 5.0L LX. It may not have had the classic Mustang looks, but it had the heart of a pony.

At Ford's 2008 model preview in Dearborn they had plenty of ponies for us sample, including the shiny blue Shelby GT ragtop in the picture. Chris and I immediately made a beeline for the Shelby and fired it up. No matter what you think about the Mustang's interior or retro styling, on a summer morning as sunny as this, the visceral thrill of hearing a big rumbling V8 with the top down is enough to make any car fan smile.

Porsche, Audi to unite on Audi R4?

Porsche of late is doing everything to remain in the news. Crystal balls are still trying to glean what Porsche plans to do with Lamborghini and Bugatti, which have thrived under Audi's watch. Now the brand, for which there is no substitute, has struck a deal with Audi to develop an entry level sports car called the R4 as well as the next Boxster and Cayman. The R-car will be the lowest rung in an "R" lineup that will hop even numbers from R4 to R10.

The R-cars will be geared not to compete with Porsche models: the R4 will ride below the Boxster and use turboed 4- and 5-cylinder engines. The R6 sandwiched by the 911 and Boxster, the second generation R8 to come in coupe and roadster versions, and an R10 supercar based on Audi's perennial Le Mans conqueror.

What will each party get? Audi gets Porsche engineering, Porsche gets aluminum spaceframes, diesel tech, DSG for all torque ratings, and they both get massive R&D savings. Both the R4 and the Boxster will then benefit from each company's pool of goodies, like night vision, heads-up display, brake energy recuperation, MagnaRide from Audi, and PDC from Porsche. The only thing left to decide is the timing: the Panamera drops in 2009, and Audi wants the R4 in showrooms in 2010. Stay tuned for a lot of in-house wrangling and a slew of hot new sports cars.

Ford's "Twin-Force" powering towards production

At Ford's 2008 model year introduction event, group vice president for global product development Derek Kuzak mentioned that the same Twin-Force technology the Blue Oval unveiled at the 2007 Detroit Auto Show in the MKR concept will soon be available on production models. Even better, Kuzak says the twin boost will result in fuel efficiency on par with comparably sized diesels. Ford has more powertrain plans, too, as the folks from Dearborn, MI usher in the best of 2003 with a manual-mode "Power Shift" automatic transmission, and multiple displacement V8s.

Ford has been playing catch-up in the competitive powertrain department for years, and these new technologies will go a long way toward Ford leveling the playing field. The Twin-Force technology in particular seems very exciting, with high horsepower and above average fuel economy promised. We'll believe the diesel-like fuel economy claim when we see it, though, since diesels come with turbochargers too, and oil burners are just more efficient than gasoline powertrains.

TechArt releases new shots of the GTstreet

There's nothing really new to report about TechArt's awesome Porsche 911 Turbo-based GTstreet. The good stuff all remains exactly as originally reported in the runup to the Geneva Motor Show. Tucked into the car's rump is a modified 3.6L twin-turbocharged flat six dishing out a reasonably healthy 630 horsepower and 604 lb-ft of torque. That's more equine propulsion than the mighty Carrera GT, and as you can see above, you can get it in green. We dig the matching stripes on the wheel rims, too. In fact, based on everything we've seen so far, there's really not a whole lot not to like about the GTstreet. 60 mph arrives in a scant 3.2 seconds, and when equipped with the full aero kit shown, the top speed is a manufacturer-claimed 214 mph. Very impressive, to say the least.

Ford offering 0% APR financing on all 2007 Mustangs, including Shelbys

Yes, you read that headline correctly. It seems that Ford's offering 0% APR financing over 36 months on all new 2007 Mustang purchases (from dealer stock) through July 9, 2007. The tip came in via a California Ford dealer, and a quick visit to the Ford Direct website confirmed what his email said.

The reason this seemed worth mentioning is that we almost never hear of deals like this on desirable cars like the Mustang, particularly the higher-end GT models and up. From what we see on the website, it applies to the 2007 Mustang V6, Mustang GT, Shelby GT, and Shelby GT500. Lately, the only promos we've been seeing on TV, etc. focus on deals related to the V6es with the Pony Package, etc. The 0% deal that's been available since June 28 was completely off our radar screens until now.

If you're in the market and can swing a 3-year deal, this might be worth looking into, particularly if you're shopping for a V8 Mustang. Don't expect any favors from dealers when it comes to Shelby pricing, though.

RetroVette: Castagna Aznom unveiled

One of the most exciting recent developments in the industry, by this writer's account at least, is the re-emergence of the coachbuilding industry. Cars like the Fisker Latigo and Zagato Ferrari 575 GTZ have heralded a revival of the long-lost segment that inherently gives birth to some of the most unique automobiles on the road. It was only a matter of time until the Italians picked up where they left off by crafting unique Corvette-based sportscars.

Italian coachbuilder Castagna Milano, originally founded way back in the 1850s and revived in the 1990s, has created a number of bespoke models, including the Imperial Landaulet concept and a slew of custom Minis. The carrozzeria's latest offering, the Castagna Aznom, was previewed in skeletal form back in April at Monaco's Top Marques show, and the firm has now released further details and images.

Based on the Corvette Z06, the Aznom also draws on retro Corvette styling elements, blended with thoroughly modern design features to create a heart-stopping supercar. The egg-crate grille is drawn from the original '53 Vette, slab-sided flanks from the '58 Stingray and fenders from the '56 SR-2 Sebring race car. On the contemporary side of things, LED rear lights, retracting rear wing, three-section rear diffuser and F1-style fender-mounted carbon-fiber wing mirrors round out the design. Those sharp five-spoke wheels measure 20 inches, shod in 285/30 and 335/30 Pirelli PZero rubber front and rear respectively, housing 356mm cross-drilled discs with six-pot calipers fore and 340mm discs with 4-pot calipers aft. The cockpit even features a Google Earth-powered sat-nav system.

Whether you love or hate the unique styling, the Aznom has the "go" to back up the "show". Castagna has thoroughly massaged the Z06's 7-liter V8 from 500 horsepower to a whopping 750, and with the use of carbon fiber, aluminum and magnesium bodywork, has trimmed the weight down to 1,400 kg. With that magical formula of more power and less weight, the carrozzeria puts the performance figures at 0-60 in a scant 3.4 seconds on its way to a claimed top speed of 217 mph.

Latest: Alfa Romeo to produce 8C Spider in 2008

Following the initial confirmation from Alfa Romeo that the drop-dead-sell-my-soul-and-both-kidneys-gorgeous 8C Competizione was going into production, however limited, the temporarily satiated hearts and minds of Italian sportscar fans (and really, who isn't a fan of Italian sportscars?) turned to the next obvious question: what about its equally jaw-dropping open-aired sister, the 8C Spider? We've been patiently awaiting any indication from the Milanese automaker, and the latest reports suggest that Alfa will indeed produce a limited run of the rolling piece of alfresco art.

Italian automotive publication Quattroroute claims that the 8C Spider will begin rolling out of the factory at the end of next year. Like the instantly sold-out fixed-roof version, only 500 examples will be produced, with a corresponding price increase to €180,000.

So, seriously...anyone interested in buying a kidney?

eBay Find of the Day: Corvette supercar prototype

What you see above is the original 1992 Marocco II Corvette Prototype Supercar. What is that? We're not exactly sure. Even though the eBay seller has plenty of magazine articles pictured, information is thin on the ground for this car. It apparently went for $156,564 in 1992, which is about $123,000 above the purchase price of a Corvette at the time. What you got for your money (and still will) is an optioned up C4 with a Superblock 350 CI engine that puts out 500 hp and 500 ft-lbs. Not only does the seller claim the car does 0-60 in 3.9 seconds, it does the quarter in 11.6 seconds, tops 200 mph, gets 29 mpg on the highway, and has near zero emissions. That's right, near zero -- at least, according to the hydrocarbon test it took in New Jersey in 1993. And then there's the bodywork, which, well, doesn't suit us, but it is original. And it is one of a kind. $250,000 gets you into the action.
