The good news is that the men in white coats have figured out why washboard roads develop on sand, gravel or any other loosely-surfaced roads. Above a certain speed, any linear force interacting with the surface causes the force to skip over the surface like a rock skipping over the water. The ripples are caused by the force alternately being "thrown off the surface" and then touching down again.
The issue isn't about oscillating car wheels, nor wheels at all for that matter. The scientists performed their experiments with a flat, inclined un-suspended plow blade; when it got above a certain speed the plow blade created ripples just like a wheel does.
The bad news is that it will be long time before the phenomenon can be stopped: "Just about any time a malleable surface is acted upon by a sideways force, you will get ripples." Since it doesn't look like ripples are going away, scientists could turn their attention to suspension systems that will "eliminate the bumpy ride." Hat tip to Michael S
Any infotainment system worth its own salt has iPod integration, but we're pretty sure there aren't many vehicles with sprinkler systems in the event said iPod catches fire. One undoubtedly unhappy owner of a 2007 Saab 9-3 Combi in Sweden apparently found out first hand that leaving your iPod on your front seat is a bad idea, as investigators believe the musical bauble is the reason the wagon caught fire, turning its interior into a prop for Backdraft II.
There has been no definitive word that the iPod was the cause for the fire, and we don't know at this point whether the popular music player was charging at the time of the incident. We do know, though that there were apparently no underlying problems with the vehicle, and the fire started on the seats, where the iPod was resting.
Since iPods are still a very hot item (no pun intended), we're guessing that you shouldn't leave them sitting inside the car. Now that there is a chance the little battery-powered devices can spontaneously combust, we're not so sure they should be in your pocket, either. Hat tip to 13enS!
Most of the world has been knee deep in a wicked recession for quite a while, and auto sales have been hit especially hard. Here in the U.S., the numbers have been abysmal, as the first half of the year saw only 4.8 million sales through June. China, on the other hand, is running away with the overall sales lead, as the emergingemerged market has added 6.1 million cars and trucks to its still developing roadways. According to The Associated Press, June sales were up 36% over the same period in 2008, and they're up 17% on the year.
The big winner in the market so far this year appears to be General Motors. The struggling Detroit, MI-based automaker has seen its China sales jump by 38% this year; while its U.S. sales have tanked. Industry analysts are predicting that the overall market for passenger cars in China will be between 10 and 11 million units.
Most experts weren't expecting China to pass the U.S. in overall sales for another decade, but the crumbling American auto industry has expedited the power shift, at least for the short term. With 1.3 billion people and a healthy economy, this day was destined to come.
Navigation systems have quickly gone from being an interactive way to direct one from Point A to Point B to massive infotainment centerpieces capable of MP3 player integration, web browsing and wifi. Auto Express is reporting that GPS units could go 3D as soon as next year, because advancements in hardware could make the technology feasible with already available dual image LCD screens (like the one in the 2010 Jaguar XJ).
If you're thinking that you're going to have to wear those goofy paper 3D glasses to find the nearest McDonalds, that's not the case. Faster processors and increased memory will enable the LCD to oscillate between two images fast enough to give the illusion of depth. The incorporation of important landmarks embedded within the 3D image ought to go leaps and bounds towards finding your destination easier.
In the near term, it's likely that the functionality will first be available in aftermarket systems, with OEM models becoming available after the tech becomes a bit more mainstream. Actually, Clarion has been selling a 3D nav system in the UK for over a year and Sony and Panasonic have had the tech available in Japan, so it's more a matter of when, not if, the tech will be available in North America.
Vauxhall is rolling out the retro cool by holding an invitation-only roller skating event in North London on July 29. As part of the festivities, the General Motors division has reportedly commissioned bespoke sets of Vauxhall Corsa roller boots (seriously), and the event will even feature a "pit-stop themed hair salone with free styling from a 'huge name' in celebrity hairdressing." The secret party doesn't look to have a name, but it's got the kind of vibe that doesn't need one: "'70s disco meets Knight Rider on roller skates." If only the Knight Rider show had thought of that, perhaps it would still be on the air.

2010 Jaguar XJ - Click above for high-res image gallery
For a long time, worrying about Jaguar was the only sensible thing to do. While it was never exactly clear if the marque had (ever) achieved profitability, we enthusiasts were only too happy to give them the benefit of the doubt. After all, the English automaker serially gifted us with watershed designs. Sublime mechanical creatures like the E- and D-Type sports cars, as well as the curvacious Mark II and original XJ. How could we not be totally and utterly smitten? Yet somehow, the once proud automaker eventually found itself adrift in mediocrity, turning out maligned and slow-selling products with an unpleasant odor of unreliability as the money began to run dry. When the then Ford-owned brand launched headlong into its "democratization of luxury" strategy that resulted in the lamentable 2001 X-Type and serious talk of an SUV, well, we couldn't help but grow gravely concerned.
After all, how could a company like Jaguar - a firm that prided itself not only on voluptuous design and sporty handling but also sybaritic appointments and a refined, aristocratic manor speak with a straight face about "the democratization of luxury?"
Not only does the XJ appear to be the measure of its German competitors, it may play a strong foil for the Maserati Quattroporte and Porsche Panamera.
The very concept was oxymoronic to the point of absurdity: when a given commodity is within easy reach of the masses, it ceases to be a luxury good. Simple as that. Predictably, it didn't take long for consumers to cotton on to this revelation, and the savior X-Type was broadly lambasted and narrowly purchased.
Thankfully, the lanky Leaping Cat is at last in proud form once again, and under the new leadership of India's Tata Motors, they are building on the success of the massively impressive Jaguar XF of 2008. By our reckoning, that car was the first clear indication from chief designer Ian Callum and Company that not only did Jaguar understand that it had a past - it might have the blueprint for a bright future as well. As it reasserts its claim to the flagship slot in Coventry's lineup, the new XJ finds itself with big shoes to fill. Is it up to the task? Follow the jump to learn more.
2010 Kia Forte Koup - Click above for high-res image gallery
After strapping ourselves behind the wheel of Kia's new Forte sedan for our initial drive, we came away thinking that the new Korean was a stylish, reasonable alternative to the scads of Honda Civics and Toyota Corollas populating America's roadways. Now it's time for Kia to follow the handsome sedan up with its first-ever two-door coupe Koup, which the automaker has now confirmed is slated to hit a dealership near you later this summer.
Underneath the attractive (if derivative) sheetmetal will be seating for five thanks in part to the same 104.3-inch wheelbase that underpins the sedan. The Koup does sit lower than the four-door, though, and Kia says the ride and handling has been retuned for a sportier feel and features beefier L-shaped lower arms propping up the expected McPherson struts in front. Sixteen-inch alloy wheels and speed-sensitive power steering come standard and an uplevel SX trim stiffens things up even further.
Powering the Koup is the same set of engine options as the sedan, meaning that the base and LX models get a 2.0-liter with 156 horsepower and 144 lb-ft of torque mated up with either a five-speed manual or a four-speed automatic, while the top-level SX gets a 2.4-liter mill with 173 horsepower and 168 lb-ft torque that can be ordered with either a five-speed automatic or six-speed manual. EPA fuel mileage estimates range from 25/34 with the base engine to 23/31 with the larger engine and automatic transmission.
All Koup models include all the expected safety gear plus standard Bluetooth connectivity with steering wheel-mounted controls, a six-speaker AM/FM/CD/MP3 audio system with Sirius, air conditioning, power windows, power door locks with remote keyless entry, cruise control with steering wheel-mounted controls, a driver's seat height adjuster and tilt steering. Options include a sunroof and heated leather seats. Want to know more? Click past the break for the full press release.
Yesterday, not long after we posted a story about a gay-centered General Motors marketing video for Chevrolet's new Camaro, the video was mysteriously pulled from YouTube. As it turns out, GM itself has copped to the disappearing act, as it reportedly ordered the popular video hosting site to yank the footage.
According to a USA Today article, GM spokesman Dave Barthmuss felt that the video - which featured a pair of so-called 'go go boys in Camaro-branded underwear washing a new 2010 model - was "not appropriate and not in good taste." The footage was filmed as part of a Transformers 2: Revenge of the Fallen gay day promotion at a Hollywood movie theater.
Despite pulling the video, GM has reportedly launched a more concerted campaign to broaden the scope of its marketing efforts as it applies to the Camaro, with more overt efforts to target gays, bisexuals and the transgendered. It is not immediately clear what (if any) effect pulling the footage will have on the rest of the automaker's p.r. efforts.
General Motors has finally added the 2-Mode Hybrid powertrain to its top-level GMC Yukon Denali. There aren't any mechanical changes to the gas-electric drivetrain that's been available since 2008 in the standard-grade Yukon and its platform mates, the Chevrolet Tahoe and Cadillac Escalade. All of which means we'll see a 6.0-liter Vortec V8 engine with 332 horsepower and 367 lb-ft of torque and up to a 6,200-pound towing capacity.
According to GM, the hybrid hardware is mostly contained in the 2-Mode Electrically Variable Transmission, which features twin electric motors powered by a 300-volt nickel metal hydride battery pack. Expect EPA fuel economy ratings of 21 city, 22 highway for two-wheel drive models and 20/20 when equipped with four-wheel drive.
As far as mechanical changes go, the Denali Hybrid will bring the first application of GM's MagnaRide suspension system to the Yukon. As you'd expect in a top-level SUV, the Denali Hybrid will come fully loaded straight from the factory - the only three options will be a sunroof, rear-seat entertainment DVD system and side blind spot alert mirrors.

Enthusiasts who had hoped for an M-worthy performance upgrade may be disappointed by the largely cosmetic M Sport Package recently announced for the flagship 7 Series. But while purists have balked at the idea of a full-on X6 M (pictured above), buyers looking for a little extra oomph from their sports-activity-whatsit were undoubtedly satisfied. So it may come as a little surprise that BMW is reportedly preparing to launch an M Sport package for the X6 that also includes some power upgrades.
According to reports, the oil-burning X6 xDrive35d with the M Sport package will get a boost of 20 horsepower to 306 courtesy of the recently launched 740d's powerplant, while the twin-turbo xDrive50i will increase output by 42 horsepower over stock. Of course, there will also be a special body kit and bigger 20-inch wheels along with the requisite badging of the X6 M Sport package, all of which gives those who want a little extra sport in their ute but aren't interested in the full-on X6 M a solid choice in between. Expect the package to hit the market later this year.
