We obsessively cover the auto industry…

With more victories under its belt than any other manufacturer, you could say, in a figurative sense at least, that Porsche owns countless numbers of race tracks around the world. But here we're not talking about figuratively owning a track – we're talking about literally buying one. And Porsche has just bought Kyalami.

Kylamai, for those unfamiliar, is a grand prix circuit near Johannesburg in South Africa. Between 1967 and 1985, and again in '92 and '93, it was home to the South African Grand Prix, and has since hosted a variety of local and lower-level international races, but apparently fell on hard times. As a result, the track's owners – listed as Universal Property Professionals – put it up for auction. Bidders had to deposit four million Rand (about $380k) to participate, but after just 50 seconds, the auction was over.

The winning bid was placed – via telephone from the local press launch for the Macan – by Porsche South Africa CEO Toby Venter, who bid a reported 205 million rand (about $19.5 million) to take over the complex. The German automaker's South African division reportedly intends to keep the track open for racing, but could also be expected to use the facility for testing, customer track days and such moving forward.

It would not be the only track, after all, owned by a Porsche – even if the South African option is owned and operated independently of the German automaker and its holding company. The factory at Leipzig has its own test track on premises, there's another one in the works for the company's new US headquarters in Atlanta, Porsche Engineering owns the Nardo high-speed test track in Germany and there's probably a few more we're forgetting about, not to mention facilities like Ehra-Lessien which Porsche effectively owns through its 50+ percent stake in the Volkswagen Group.

Porsche also has a number of customer experience centers opening at tracks around the world – including LA, Atlanta, Silverstone and Le Mans – and given the new acquisition, we wouldn't be surprised to see it set one up at Kyalami as well.

Automakers conduct driver training programs on racing circuits around the world for a variety of participants: journalists, customers, even celebrities. And at a recent session of the Jaguar Performance Driving Academy at the Circuit of the Americas in Austin, Texas, the Leaping Cat marque had a couple of the Hollywood types in the paddock.

In addition to the various (evidently well-heeled) members of the public, learning how to pilot the new F-Type Coupe R on the track this time around were actors Sebastian Stan and Mena Suvari. You might recognize Stan from his roll as Bucky Barnes in the Captain America movies and Suvari from such red, white and blue favorites as American Beauty and the American Pie franchise, but both got a first-hand taste of one of Britain's finest courtesy of Jaguar.

So how did it go? Well, as one of the less-famous participants put it, it was #awesomesauce." We couldn't possibly reproduce in words her enthusiasm in person and on camera, so you'll just have to watch the video below to see for yourself.

Want to get your hands on a new 2015 Dodge Challenger SRT Hellcat, and can't wait to be the first to get one? Las Vegas will be the place to be on September 27. That's where Barrett-Jackson will auction off the very first example. And you'd better bring your checkbook, because the bidding is sure to be fierce with all the proceeds going to charity.

The supercharged Challenger with VIN 0001 has been hand-painted in Stryker Red (usually reserved for the Viper) and features special badging, documentation and accompanying memorabilia – not to mention, of course, that 707-horsepower, 6.2-liter supercharged Hemi V8. The car will be on display this weekend as well at Barrett-Jackson's Hot August Nights auction in Reno.

Not only is Dodge donating the vehicle, but Barrett-Jackson is waiving all its consignment fees and commissions so that 100 percent of the winning bid – which is sure to be mega – will go directly towards Opportunity Village, a non-profit that works to serve the needs of the mentally handicapped and their families. Check out the press release below for all the details.

Rimac Automobili is no stranger to our pages, but it's usually for the Concept_One supercar or its sleek spinoffs. Today, though, the company is talking up a feel-good alternative use for the electric vehicle's batteries: powering a wheelchair for a young fan, Rolly Bugnar, who suffers from a serious and legitimate case of range anxiety.

"We were confident that we could relatively quickly adapt our battery for a wheelchair." – Mate Rimac

So Bugnar contacted Rimac to see if the company could repurpose its batteries for his daily conveyance. Mate Rimac, the company founder and CEO, said, "Since we have already used the technology originally developed for the Concept_One supercar in other products like the high-performance Greyp Bikes, we were confident that we could relatively quickly adapt our battery for a wheelchair. ... It still took us months of development and adaptation, but we are all very satisfied with the performance and reliability of the prototype system."

What did Rimac do? It took the li-ion battery system from that Greyp G12 bike as well as the company's battery management system, vehicle control unit and human machine interface. As you might suspect, the wheelchair now has better range (37 miles vs. just six with the old lead acid batteries) and weighs less. The new batteries went from 70 pounds down to 47, and the EV has more consistent power, too. You can tell Bugnar is a true EV fan, since he likes to keep close tabs on the individual cells and he wishes his wheelchair could go faster.

Sadly, Rimac Automobili doesn't have a plan to sell any wheelchairs like this, but we expect a lot of wheelchair users would enjoy a new ride like Bugnar's. See what we mean in the video below. It might be the most heartwarming seven minutes you'll spend online today.

American fans of Formula One racing have a new team to root for as the Marussia F1 Team has named Alexander Rossi as its official reserve driver for the remainder of the season.

The 22-year-old native of Auburn, California, has advanced through the single-seater ranks since winning the Skip Barber Western Regional championship and placing third nationally in 2006. He won the Formula BMW Americas title in 2008 and proceeded to Formula Renault 3.5 and GP2 where he competes currently, winning races in both series. For the past three seasons he's driven for Caterham, racing for its GP2 team and acting as test driver for its F1 team. Once the team was sold, however, Rossi jumped ship. He's driving for the championship-winning Campos Racing team in GP2 and just announced his signing with Marussia on Thursday.

The move is only a minor step up for Rossi as the Marussia team is only two points ahead of Caterham this season, but will hopefully lead to the young Californian getting some seat time in an official test session or two – if not being called up to replace Max Chilton or Jules Bianchi in the race seat at some point before the end of the season or maybe getting promoted to a full-time drive for next year's championship.

Rossi is the first American to break into F1 racing since Scott Speed, who left the series in 2007. The last American driver to win a grand prix was Mario Andretti back in 1978.

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.

In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.

Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

According to Autocar, the sophisticated system is powered by its own, separate 48-volt electrical system that drives a 7-kilowatt (9.4 horsepower) motor to spin the supercharger. When the internal combustion engine is at low revs, it provides the needed boost but shuts off as engine revs rise to let the turbos take over.

"Right now, there are so many structurally deficient bridges in America that, if you lined them up end-to-end, they'd stretch from Boston to Miami."

Secretary of Transportation Anthony Foxx (pictured above) has banded together with 11 of his predecessors to issue a stark declaration to the US Congress – our infrastructure is crumbling, and the proposed bill to keep the Highway Trust Fund going until 2015 is simply not a suitable long-term solution.

Saying that the bill "will not 'fix' America's transportation system" and that "America's transportation system [has never] been on a more unsustainable course," Secretaries of Transportation for the past 35 years and seven presidents laid out some truly troubling stats.

In the past five years, Congress has passed a total of 27 short-term funding measures, whereas the norm used to be six-year plans. The country's infrastructure has suffered due to this kick-the-can-down-the-road mentality.

"Right now, there are so many structurally deficient bridges in America that, if you lined them up end-to-end, they'd stretch from Boston to Miami," the letter reads. For those wondering, that's a distance of over 1,250 miles, as the crow flies.

Citing the American Society of Civil Engineers, it's estimated that the US would need to invest $1.8 trillion by the end of this decade to bring roads up to what the ASCE calls "adequate levels." Of course, what constitutes "adequate levels" is open to debate, but it's clear that there needs to be an enormous investment to sort out America's deteriorating highways and byways.

Those troubling stats are simply near-term issues, though. A lack of highway funding and infrastructure repair in the present could be even more troubling in the more distant future. Pointing out that the US population will increase by 100 million come 2050, Foxx and Co., claim that an additional 14 billion tons of freight will need to get from A to B to support that population. Now, how is that going to be possible on derelict infrastructure? Secondary to that, how much more wear and tear will those systems suffer with all the additional freight haulers moving about?

The note ends with the Secretaries of Transportation calling on Congress to follow in the footsteps of their predecessors, something we sincerely hope happens:

"Until recently, Congress understood that, as America grows, so must our investments in transportation. And for more than half a century, they voted for that principle – and increased funding – with broad, bipartisan majorities in both houses.

We believe they can, and should, do so again."

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.

According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower – very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.

None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.

Big plans are afoot at Bentley. The quintessentially British automaker has just about signed off on the final version of its new SUV, and will surely roll out more versions of the Continental in the coming years, but that's not all. It's said to be considering a new sports coupe smaller than the Continental GT, but the latest reports coming in from the UK suggest that it also has plans for the Mulsanne's platform.

Currently, the Mulsanne is only available in one configuration, but Bentley is widely expected to be bringing a new, more powerful Mulsanne Speed to the Paris Motor Show this fall with around 550 horsepower. That's not all, however, as word comes in that the Flying B marque is planning to re-introduce both the Azure and the Brooklands as competitors to the Rolls-Royce Phantom DHC and Phantom Coupe, respectively.

For those who don't remember, the Azure and Brooklands were a pair of two-doors based on the Arnage that preceded the Mulsanne at the top of Bentley's range. The Azure was a convertible and the Brooklands a fixed-roof coupe, both of them larger than the Continental GT and powered by the company's evergreen (yet decidedly un-green) 6.75-liter V8.

Both were phased out, however, along with the Arnage before the current Mulsanne was introduced in 2010. And ever since then, Bentley has been rumored to replace the duo with new versions based on the Mulsanne. But despite having shown the Mulsanne Vision convertible concept to a select group of customers at Pebble Beach a couple of years ago, the project was shelved.

So what's changed, you ask? The guard, that's what. When Bentley unveiled the Mulsanne Vision concept, Wolfgang Dürheimer was the CEO. Then he was relieved of his duties, and Wolfgang Schreiber, who replaced him, nixed the project's development. Now that Dürheimer is back in charge at Crewe, it seems like the convertible is back on the table. "And if we do the Azure," Dürheimer told Auto Express, "the Brooklands just comes automatically." That is, of course, unless Bentley decides to do something out of the ordinary and make a four-door convertible "parade car" instead.

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.

It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.

We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.

There are some things in this industry that we're perplexed by, like the infotainment system on our long-term Subaru WRX or why the Mitsubishi Mirage is allowed to exist, among other things. Let's add one more to that group, with the Lexus GX. It's not a particularly bad vehicle for a big, body-on-frame brute, remaining one of the only true SUVs in the mid-size luxury class, alongside the equally old fashioned Land Rover LR4.

Considering these things, then, what we're about to tell you makes very little sense – sales are up 135 percent through last month. The Japanese luxury marque has moved over 5,300 during the first six months of 2014, owing in no small part to a significant price drop over the 2013 model. Today, a GX starts at $49,085, while a year ago, it was $53,445.

Don't mistake this price decrease for charity, though. Lexus specifically built a lower-cost GX to lure in customers. According to WardsAuto, faux leather covers the cabin rather than the real stuff, while the overall package is decontented relative to what you might find in a typical Lexus.

"That was our target in terms of positioning, to bring a true SUV down to a (CUV) price point," Brian Smith, VP of marketing for the brand, told Wards.

While the price cut has helped drive customers into showrooms, Lexus isn't selling many sub-$50,000 GXs.

"We've been successful with that [base grade], however it's not the biggest chunk of our volume," Smith said.

Base sales only constitute a fifth of the GX's totals, with customers generally flocking to the better outfitted GX Premium, which coincidentally starts at just a few hundred dollars more than last year's base model.

Despite this big increase in sales, the GX's future is far from certain, Smith said. Lexus is allegedly, according to AN, looking at swapping the GX from its truck-based roots to a proper unibody platform, in order to better compete dynamically with CUVs like the Acura MDX. Smith doesn't want that, though, citing the SUV's 6,500-pound towing capacity.

"I think there's a need for towing capability, without having to go all the way to an LX," Smith said. "So we're doing everything we can to continue to keep Toyota focused on the need for GX."

What are your thoughts? Should Lexus retain the GX as a body-on-frame vehicle, or should it just leave towing duties to American brands? Are you surprised to hear the GX still exists? Let us know in Comments.

It may not be a flying car, and it may not even be a Hoverboard. But we don't care. A hoverbike is still incredibly awesome, and there's now a chance to bring just such a device to the real world thanks to Kickstarter.

Designed by an Kiwi bloke in London named Chris Malloy and seen on these very pages three years ago in prototype form, the would-be hoverbike is a sort of combination between a motorcycle and a helicopter, relying on spinning rotors front and rear to generate lift. Past versions of the machine used two rotors, powered by a a 1,170cc boxer engine from BMW, but what you're helping build is rather different entirely.

Since we last featured that Hoverbike prototype, Malloy has further refined the design, changing from two rotors to four, but it's still far from being ready for production. That's the bad news. The good news is that small-scale testing has proven this new design, and third-scale models, powered by electric motors and controlled remotely, are now ready for those with a bit of expendable income to get their grubby mitts on.

As much as we'd love to see a Kickstarter campaign for the fullsize Hoverbike, we think these radio-controlled, unmanned drones are pretty darn cool in their own right, and Malloy says this project will help fund the real thing in true human-scale. Check out the Kickstarter campaign here, and scroll down below for some video.

Ford is back at the Experimental Aircraft Association AirVenture air show in Oshkosh, WI, on July 31 auctioning off its seventh Mustang for charity, and this is one seriously mean looking 2015 'Stang. All of the money from the sale goes to give free introductory flights to young people to get them interested in aviation.

We recently saw this latest EAA Mustang as a sketch. However, it looks a whole lot more menacing in person. Dubbed the Ford F-35 Lightning II Edition Mustang, it takes liberal inspiration from Lockheed Martin's latest fighter jet, and the customization makes the pony car look ready for a role in Top Gun.

On the outside, the special Mustang wears titanium-color paint that's offset by a black and yellow stripe running from hood to rear. Out back things get really wild with a mix of bright yellow and black that flows diagonally all the way to the rear spoiler. The design is based on the livery of early production F-35s. If the rousing color scheme isn't enough to get you interested, the car also gets a carbon fiber front splitter and rear diffuser, lowered suspension and a set of custom 21-inch wheels with yellow brake calipers.

Inside, the design continues to take inspiration from the fighter with gold-tinted windows to match the radar shielding from the plane's cockpit. To keep the driver and co-pilot planted, there are two big Recaro sport seats with more yellow accents, and in case you forget what's influencing the car, the door panels and floor mats show the F-35.

Ford's work with the EAA has raised over $2.5 million for charity, and last year's Air Force Thunderbirds-inspired car brought in nearly $400,000. With the 2015 Mustang being so highly desired, you might need some deep pockets to put this one in your garage. Scroll down to read more about this fighter-inspired coupe.

Both of America's domestic luxury brands seem to be stuck in neutral.

It's ironic that Cadillac and Lincoln got new bosses within days of each other this month. It's also a commentary on the fact both of America's domestic luxury brands seem to be stuck in neutral.

Cadillac has received barrels of good ink in recent years, thanks to its sporty, fun-to-drive cars with gaudy horsepower figures and eye-catching designs. The problem is sales have been uneven, and this year they've fallen 1.9 percent to 82,117 vehicles.

Enter Johan de Nysschen. You know him from such roles as the head of Audi in the United States and more recently, as the global boss of Infiniti. Both brands have somewhat underdog status compared with segment leaders Mercedes-Benz, BMW and Lexus, and de Nysschen was lauded for his work at his previous stops, overseeing sales and product successes.

Cadillac went out and got a "name" with a proven track record. The 54-year-old South African brings strong leadership and industry credibility to a brand that needs both. He'll be tested right away, as 554,328 Cadillac CTS and SRX models were recalled in June in the United States for ignition switch problems. More recalls involving Cadillacs and other General Motors vehicles for a welding problem was also announced in July.

He's taking over for Bob Ferguson, who had been dividing his time between Cadillac and handling GM recall response on Capital Hill. Ferguson moved to a full-time role as GM's top public policy and government relations executive in July.

Meanwhile, Ford tapped a relatively obscure engineer, Kumar Galhotra, to lead Lincoln. He's replacing an industry star, Jim Farley, who's giving up the reins at Lincoln to focus on his other job – overseeing Ford's global marketing efforts.

Galhotra doesn't have as much name recognition as Farley or de Nysschen, but that means nothing. Lincoln needs momentum, and the only way Galhotra will ultimately be measured is through increasing sales and strengthening the product portfolio.
