At last week's tony Design Miami reveal of the 2011 A8 luxury cruiser, we were able to corner Johan de Nysschen, Audi's executive vice president in North America, and ask him for some tasty tibits on the brand's upcoming products, including the A8's sexier derivative, the A7.

In addition to giving us the first official confirmation of the A7's existence, de Nysschen revealed that the four-door coupe model will slot in "a little bit below" the new A8 in terms of pricing, just as we expected. Of course, it's worth noting that the 2011 A8 faces a price bump due to substantial increases in content and technology, so when the A7 finally comes to the States, the average model is likely to sticker at around $82,000-$83,000, which de Nysschen says is about the price for a typically equipped 2010 A8 (pricing starts at $74,550 plus delivery).

Based on Audi's new longitudinal modular platform technology, the A7 will be clearly related to the A8 (and the A6 replacement that will follow it), and de Nysschen says that the 2009 Detroit Auto Show Sportback concept car serves as a "very reliable indicator" of what the production model will look like. Judging by recent spy shots from our friends at KGP, that very much appears to be the case. While parts commonality will be "substantial," de Nysschen says that the A7 will not use the full aluminum spaceframe design of the A8, although it will have aluminum elements.

As expected, the A8 will launch Stateside in both standard and long-wheelbase formats, with the latter predicted to make up the lion's share of the volume (the A8L presently accounts for about 80 percent of the model's sales).

We asked De Nysschen about how the two models will interact in the full-size luxury sedan segment, and he noted that:

"This top end segment is characterized by more conservative people, and we need to clearly take lower levels of risk with a flagship model [the A8]. But we recognize too that there is a sizable enough cluster of customers in that same segment who are ready for a more avant-garde design [the A7]. So we will essentially be positioning two cars into the same segment, which means that independently, the volume each attains is not that significant, but when you put them together, it will mean that our share of that segment will grow quite dramatically."

All-in De Nysschen thinks that the A8 will account for about 4,000 to 5,000 sales per year in the U.S., and the less costly A7 could clear 7,000-8,000 additional units.

And what of a high-performance S8 to take on Mercedes-Benz's AMG lineup, or the A5 Sportback? Click through to the jump for more details.

1962 Corvette C1-RS is a worthy Goodguys Street Machine of the Year

1962 Chevrolet Corvette C1-RS - Click above for a high-res image gallery

It takes a lot to win the the Goodguys Street Machine of the Year award, but this custom 1962 Corvette convertible you see here easily deserves the honor. The car not only looks incredible, but it posted the fastest time at the Goodguys autocross track as well! Every single one of the body panels on the car has been modified, and the majority of the components are constructed either of aluminum or carbon fiber.

Powering the C1-RS is an LS7 V8 putting out more than 600 horsepower, but we were most impressed with the eight carbon fiber intake trumpets on either side of the engine that bring air into the intake manifold. The interior was beautifully crafted as well, with a custom fabricated aluminum dash and console and Alcantara and leather seats. Check out the high-res gallery below to see all the details yourself, or follow the jump to read more about the car.

ABC News caught up with Toyota Vice President Yukitoshi Fun

Remember Toyota's massive 3.8 million unit unintended acceleration recall that was attributed to pesky floor mats? It appears defective floor mats doesn't tell the whole story, as the Department of Transportation and the National Highway Traffic Safety Administration declared in a statement that "this (unintended acceleration) matter is not closed," adding "removal of the floor mats is simply an interim measure, not a remedy of the underlying defect in the vehicles."

Up to 2,000 Toyota customers claim to have experienced a sudden surge of acceleration, and some reportedly told ABC News that they didn't even have the recalled floor mats in their vehicles. Even more disturbing are the results of an ABC News investigation that reportedly found "hundreds" of accidents and up to 16 deaths as a result of unintended acceleration.

Four of those deaths occurred in August when an off-duty California Highway Patrol Officer, traveling with his wife, daughter and brother in-law, were killed after their Lexus accelerated uncontrollably. The driver's brother in-law called 911 and said that the brakes didn't work before the vehicle reached an intersection, struck another car, went into a ditch and caught fire. Some Toyota owners feel there is an electronic glitch in the system that controls the throttle and the ABC report shows that there is some anecdotal evidence which illustrates that incidents rose after the system was put into place in 2002, but so far, NHTSA has found no evidence to support those claims after six investigations.

ABC News caught up with Toyota Vice President Yukitoshi Funo (pictured second from left) and asked him if Toyota was covering anything up. Funo replied "It is not part of the Toyota culture and Toyota way to cover up anything," adding that the Japanese automaker is working with NHTSA to come up with an agreement on how to proceed going forward.

If you own a Toyota or Lexus and you are concerned about this issue, it appears that there is little that will be done in the short term other than tie down or remove the floor mats. If you do experience the acceleration issue, Consumer Reports suggests shifting your vehicle into neutral, pressing the brake and holding it down in an effort to bring your vehicle to a stop. This post and video from CR demonstrates how to effectively resolve the situation, and the risks of pumping the brakes. Turning off your vehicle could be a bad idea, as turning off the engine will also result in the loss of power steering and power brakes.

Grunewald Racing Camaro sets its sights on 2010 Formula Drift season

Conrad Grusewald has been an occasional participant in the Formula Drift series for the past several years with a supercharged C5 Corvette as his vehicle of choice for piloting around clipping points and narrowly missing concrete barriers while in opposite lock. For the 2010 season, however, he plans to step up the efforts with an all new 2010 Camaro built specifically as a drift car with Hankook Tire as the lead sponsor.

In addition to providing the Camaro for Grusewald, Chevrolet also pitched in an LS-A crate motor from GM Performance Parts that should produce more than 600 horsepower at the wheels. The car also features an Eibach suspension, carbon fiber body panels from Seibon, Forgeline aluminum wheels and more. Expect to see more of this car when the Formula Drift season starts in April, but until then you'll have to settle for our gallery of high-res photos below.

Renault board considering following Toyota out of F1

Things have never been this bad for the Renault F1 team. Their performance is light-years behind where it used to be, their star driver is bolting once again, their top management has been thrown out of the sport in disgrace, and its biggest sponsors are leaving en masse. And now, following months if not years of speculation, the French automaker could be preparing to cut its losses and shut down its racing team altogether.

Reports indicate that Renault's board of directors is currently weighing its options, with possibilities including maintaining its full participation in the series, reverting to acting as an engine supplier for other teams (like Red Bull), or following Toyota and BMW out of the sport before next season. However reports that the FIA is considering taking legal action against Toyota for breach of contract which locked the company into the series through 2012 could make the decision a little more difficult.

The anticipation must be especially gut-wrenching for Robert Kubica, who just signed with Renault for next season after BMW Sauber exited the series. One way or another, the company is expected to announce its decision in the coming days.

Introduction to Karting - Part 2 2009

Welcome to the second installment of our Introduction to Karting series. Hopefully the first piece piqued your interest with tales of tiny machines pulling 3 g in the corners then hitting 60 in under three seconds on their way up to over 140 MPH. (Well over, as it turns out; one commenter indicated he hit an indicated 156 this season.) That kind of performance is unequaled outside of top-level formula motorsport, yet is available to anyone with some disposable income and a passion for going quick.

However, karting isn't for everyone so suitably endowed. The physical demands placed on a kart racer are hard to comprehend until you're in a fast turn, holding your breath because you can't inhale, feeling like your head is going to fly off and land somewhere in the pits. Chances are it won't, but whether or not you can withstand that while maintaining a good racing line and keeping an eye on a swarm of opponents is an important thing to find out before breaking out the charge card. The best way is, of course, to try it, and given the big up-front cost to buy a kart, a rental is the way to go.

To get our first real experience we signed up for an afternoon's racing school. We walked the track, worked with multiple instructors, got a lot of advice, had an impromptu race, and stuck it out for way more seat time than was probably advisable for a newbie. How'd we do? Read on to find out, and see some videos of our on (and, occasionally, off) track antics.

GM marketing boss Mark LaNeve apparently unaware that diesel is now cheaper than gas 2009

Over the last several years, we've heard a lot of excuses from many auto executives as to why their companies aren't offering diesel engines in their American market cars. Yesterday, General Motors' Mark LaNeve, the company's vice president of sales and marketing, made an appearance on C-SPAN's Washington Journal. The final question of the segment came from a viewer wondering why GM has failed to offer U.S. consumers the chance to buy some of the high-mileage diesel cars it offers in Europe.

It would appear that LaNeve might have done better to take a pass on the question. Instead of talking about the cost of making those diesels meet U.S. emissions regulations or the difficulty in helping Americans overcome the misconceptions about the fuel, he claimed that no one has successfully cracked the diesel passenger nut in the U.S. (which based on VW's May sales appears to be wrong). More startlingly, LaNeve went on to claim that diesel is $1.25 a gallon more expensive than gasoline. According to the Energy Information Agency, the national average for diesel this week is $2.35 / gallon while regular gas is $2.52 or $0.17 more than diesel. Admittedly, the fact that diesel is now cheaper than 87 octane gas is a recent development (a trend that nobody is sure how long it will last), but – going on national television and quoting outdated fuel prices as a reason for your bankrupt company's business decisions... well, that doesn't strike us as a terribly hot idea.

You can hear the question and response at 20:30 into the video replay over at C-SPAN.
