Not long after we learned that the famous Top Gear trio was in the U.S., a fan managed to snap some shots of Clarkson, Hammond and Mays testing their favorite examples of American muscle at the Bonneville Salt Flats in Utah. The hosts made their way to salt flats by way of Reno, Nevada where they had a few modifications done to each vehicle in the name of high speed safety, namely driveshaft loops and fire extinguishers. If you saw our previous post on the subject, you already know that Clarkson is driving a Corvette ZR1, Hamster a Challenger SRT8 and May the super-fast but still luxurious Cadillac CTS-V, a car that shares much of its supercharged V8 architecture with the new force-fed mill in the ‘Vette. We can already surmise that the ZR1 easily took top honors at Bonneville thanks to its slippery shape and abundance of power. Now, which car wins the comparison test? We look forward to next season to find out. Check out the gallery below for more pics of the action going down, or click here and follow the photostream.

More news on the 2010 Chevy Camaro has been revealed after the Camaro SS made its live debut at Indy Bash 2008. According to this thread on the Camaro5.com forums, dealers will begin taking orders for Chevy’s new sportscar on October 13th, though pricing may still not be available at that time. Also revealed are a list of performance and appearance accessories that includes a rear spoiler, rear diffuser, ground effects package, many different kinds of stripes, different engines covers for both the V6 and V8 models and performance parts like a cold air intake, catback exhaust, shorty headers and Hurst short throw shifter. Interior accessories include the obligatory carbon trim kit, a body-colored lighted trim kit, floormats and a nostalgic looking subwoofer, while a selection of chrome and painted wheels will also be offered. Check the link below for more images that reveal exactly how fast and furious you can make the new Camaro look.

Live images of the Chevy Orlando, possibly shot during GM’s own photo session, have surfaced online, showing the seven-seat crossover in all its conceptual glory ahead of its unveiling at the Paris Motor Show next week.

The Orlando shares the same Delta II platform as the Chevy Cruze, with power provide by a 2.0-liter turbodiesel, and blends some traditional Chevy styling cues with a blocky, upright silhouette and show-friendly lighting tricks. Unlike other pie-in-the-sky concepts, the Orlando’s interior looks downright drivable, with two-tone leather seats, a traditional steering wheel and a center stack that wouldn’t shouldn’t look out of place on anything rolling off the General’s assembly line.

All the details and plenty of live images from the show floor are coming in just over a week.

It always happens this way. Shortly after a new performance car is released to the public, it will find its way to a dyno shortly thereafter. When that new vehicle is the new performance king of the automotive world, aka the 2009 Corvette ZR1, our collective interest is piqued. So, how does it fare on the rollers? Two separate ‘Vettes were tested, and the average output was about 535 horsepower at the rear wheels. After factoring in the normal 15-percent drivetrain losses for a rear-wheel drive car, that’s pretty darn close to the claimed 638. After a bit of tinkering the team got that number up near 570, saying it’s running a bit rich from the factory. Click here for the full graph.

Until the V-Spec GT-R is unveiled the ZR1’s most natural competitor might be the normal Nissan GT-R; despite the pricing disparity between the two, they are the two most amazing performance bargains currently on the market. For what it’s worth, the GT-R seems to be averaging about 420 horsepower at the wheels. Apples to oranges? Sure, but it’s always fun to throw a little more fuel on the fire. If we didn’t do it, you know it would come up in the comments. And so it will, have fun.

GM is not going to let the Volt or its E-Flex powertrain get lonely. The first Volt — the one due in late 2010 — hasn’t been finished yet, yet is so popular that GM is publicly theorizing about how far it can spread the technology through the empire. Ideas include a smaller car with a smaller battery pack that could go 20 miles on pure electric, and be much cheaper. A proper wagon, just “a little bit bigger,” could also make the cut.

And those variants don’t all need to be Chevrolets. Other GM brands will certainly be blessed with Volt technology, if not an outright case of brand engineering. Cadillac is one of the wolves thought to be circling the Volt’s henhouse, and using Volt systems in a Caddy might allow GM to make a profit on such a car without tax breaks. If there were a more economical Volt with a shorter electric range, Saturn would seem to be a prime candidate.

It looks like the sole E-Flex powertrain option not planned is an electric-only car, one without a range-extending gasoline engine. GM feels that people would find it too risky to have no backup. But back to that first car, the plain vanilla Chevy Volt that’s still two years away from showrooms – a Volt team member doesn’t appear to have forgotten the prime directive: “You always have to do the first car right and well.” Amen.

When GM and the UAW agreed to a new contract in 2007, several new models and the plants in which they would be built were agreed on. Drastic shifts in customer tastes are changing those plans rapidly, and the General is scrambling to deliver. GM was planning to build a seven-seat crossover based off its global Delta small car platform at the Detroit Hamtramck plant next year, but the Wall Street Journal is now reporting that the vehicle will no longer be produced for the US market.

The small MPV, which is being unveiled at the Paris Motor Show in concept form as the Chevy Orlando, will still be available in Europe where small seven-seaters are much more popular than here in the States. The small crossover will instead be replaced by a compact vehicle from Asia, possibly the Chevy Beat. However, GM never designed the Beat to meet U.S. crash-test standards, but hopefully the extra resources freed up by nixing the Orlando’s U.S. launch could make that happen in quick order.

The crew from Camaro5 were on hand to capture the first live unveiling of the Chevrolet Camaro SS at Indy Bash 2008, and although we’ve seen the silver-hued coupe on numerous occasions, this is the first time we’ve gotten a glimpse inside.

As you’re undoubtedly already aware, the Camaro SS is powered by a 6.2-liter LS3 V8 putting out 422 hp and 408 lb.-ft. of torque, and in this case power is sent to the rear wheels through a six-speed automatic gearbox.

The most striking element of the SS’ interior is the shiny plastic door panels and dash trim that matches the two-tone black and leather seats, with contrast stitching. It’s very racy, and should tie in nicely with the SS badges fore and aft.

We’ll be able to see the Camaro SS up close at the Paris Motor Show next month, so stay tuned for our impressions from the floor.

Reports are coming in that the General is considering selling its medium truck operations to Isuzu. This news is totally unconfirmed by both parties, though Isuzu says it would be more than willing to listen if GM felt the desire to talk.

All of this comes shortly after Navistar chose not to follow through on its non-binding agreement to purchase the commercial truck unit from General Motors after seeing what’s been happening with the U.S. economy and gas prices. After that deal went sour, GM said that it would continue looking for options, so this particular piece of the rumormill pie is anything but surprising. We contacted GM to see if the automaker had anything to say regarding the hubbub, and, as expected, it’s staying tight-lipped for the time being. An Isuzu tie-up makes some sense, as the two truck makers have had dealings together in the past, most notably in the design of GM’s current mid-sized trucks, the Chevy Colorado and GMC Canyon.

General Motors car czar Bob Lutz hopped online yesterday after the official unveiling of the 2011 Chevy Volt to address criticism of the car’s design that began to surface after images of the series hybrid were leaked online last week. Most complainers have decried the fact that the production Volt looks little like the Volt Concept that debuted at the 2007 Detroit Auto Show. This is certainly true, but Lutz points out on GM’s Fastlane Blog that while automakers often use design to make an emotional connection with customers, the Volt will instead use the technology beneath its skin to make that same connection. What it looks like on the outside has been largely shaped by the “Form follows Function” rule, with designers given as much leeway as possible to add some style as long as it doesn’t violate the Volt’s prime directive of fuel efficiency.

We also went back to our coverage of the 2007 Detroit Auto Show and looked at comments left on our post covering the reveal of the Volt Concept and, as we thought, not many people were talking about its design at the time. We’re not sure where all these fans of the concept’s design have come from all of a sudden, but they certainly weren’t around when it was debuted. Perhaps we couldn’t hear them over all the talk about its technology.

Video clips of the Corvette ZR1 strutting its stuff on track can be found virtually anywhere on the internet. But that doesn’t mean we’re tired of seeing the beast in action, particularly if the video happens to feature another new staple of GM’s sporty lineup. The latest internet discovery is a grainy, sometimes barely audible, clip of the Chevrolet Camaro SS tackling the twisties with a guest appearance by a jet black ZR1. The video begins with the new muscle making a go on the course all alone. Then later, it appears trailing behind the infamous supercharged ‘Vette.

From what we can see, the Camaro’s chassis seems to be nicely tuned. The body roll is not substantial and the pony car takes a seat quickly when entering a turn with no floaty oscillations. Hopefully the short but sweet video tease is a direct indication of the production setup. Follow the jump to view things for yourself. Thanks for the tip, Xeyad!
