We're not saying it doesn't happen, but it's not that often you see a door coming off a car during a race without the vehicle coming in contact with another racer.

One such incident took place at last weekend's Losail International Race Days in Doha, which is Qatar's largest city, when race driver Rob Frijns bid farewell to the door of his Porsche 911 GT3 RS.

It looks amusing until the video switches to the dash-cam view of the driver following behind. As you can see, this could have easily turned very ugly…

Wouldn't it be great if your regular Honda Civic hatch would look, sound and go like the new Civic Next Generation Touring Car (NGTC)? We mean, sure it would pose some problems in everyday use, but something tells us that those pesky morning rides to work would become far more entertaining...

However, back to reality, we found the first video footage of Honda UK's new BTCC racing model filmed during its shakedown at the Brands Hatch racing circuit in England, which you can watch right after the break.

Just be warned to turn down a notch the volume on your speakers cause thing is loud, really loud…

On October 23, 2010, professional racing drivers and sisters Angela and Amber Cope made history by being the first twins to compete in one of the top three series in NASCAR.

The two sisters made their debut at the Camping World Truck Series race with Amber finishing 26th and Angela 30th.

Now, the 28-year old twins are following in the footsteps of NASCAR driver Danica Patrick by posing in the March issue of the men's magazine Maxim with a hot photo-shoot, a taste of which you can get in the video after the break.

Almost immediately after the debut of the production 2013 Fusion sedan at last month's Detroit Motor Show, Ford lifted the wraps off the NASCAR version that will compete in the next season starting from the Daytona 500 in February 2013.

Like all NASCAR racers, the resemblance between the production 2013 Fusion and its competition sibling is only skin deep as the two models are worlds apart when it comes to the inner workings.

If you follow the break, you'll find a fresh set of photos of Ford's new and old Fusion NASCAR race cars, some of which were shot during the presentation at the Daytona International Speedway.

When you have something special in your arsenal as Lexus does with its limited production LFA supercar, it's only reasonable that you'll want to show it off as much as possible.

In its newest video, the Japanese company summoned the help of former F1 driver and double Le Mans winner, Alex Wurz, who sat behind the steering wheel of the $375,000 carbon-fiber LFA and took it for a ride around the Autódromo do Estoril circuit in Portugal.

Follow the jump to find out how it went down.

The SL63 AMG may have been a nice surprise, but the real reason why the press was gathered today at the Circuit de Catalunya track in Spain was the launch of Mercedes’ brand-new fighter for the 2012 Formula 1 championship.

Mercedes GP chose the first day of FIA’s second official pre-season test in Barcelona to unveil the W03. Admittedly, it has come late to the party, as the company's F1 racer was launched later than most of its competitors, but the team reckons that this was a good thing, since it gave them more time to hone the car.

Subaru's motorsports division has been busily working on its new BRZ GT300 racecar, which made its world premiere alongside the regular BRZ sports coupe at the 2011 Tokyo Motor Show in December.

The Japanese automaker put the BRZ GT300 through its paces this past weekend at the Fuji Speedway in Japan as it prepares for the 2012 Super GT championship, which starts at the end of March.

In its two last generations, the European market Honda Civic hatchback has followed a different path from its sedan siblings in other markets; however, the admittedly impressive looking Civic you see pictured here isn't the regular model but the Japanese firm's new contender in British Touring Car Championship (BTCC).

Revealed without its racing colors, the new Civic Next Generation Touring Car (NGTC) made its first public test outing today at the Brands Hatch motor racing circuit in England.

A tenth of a second is an eternity in Formula 1. In qualifying runs, it can mean the difference between the pole position and third place or even worse at the starting grid. During a pit stop, it can make or break your entire race.

Moreover, if you multiply that tenth by 50 times or more, i.e. the number of laps in a Grand Prix, it is the difference between spraying the champagne on the podium and heading to the pits with your head down in disappointment.

That valuable split-second is what hundreds of people strive for months each year. Shortly after the new season starts, the designers back at the factory start working on next year’s car.

Any new Ferrari model is fast, but in today's world, the Prancing Horse brand is not the only automaker building rockets on wheels.

Of course, there are various definitions of fast (top speed, acceleration, circuit laps etc) but in this video we have a stock Ferrari 458 Italia with 570-ponies under its mid-mounted bonnet taking on three tuned models, including a 750HP Audi RS6 Evotech, a 600HP Nissan GT-R AMS and a 750HP Corvette ZR1 C6 Lingenfelter, on a 1 mile (1.6 kilometers) run.

See how it went down in the video that follows after the break.

We're always up for some video footage of sports cars running a hot lap around a track, even if said sports car is one we've shown more times that we can remember before and after its official presentation

Those of you tempted may follow the break to watch the new Subaru BRZ rear-wheel drive coupe being driven around the Fuji Speedway in Japan.

Dumps trucks ain't our cup of tea but there's always an exception to the rule, and this is it: a Kenworth T800 with a turbo setup that's good for more than 1,000 horses at the tires!

According to the folks over at Bangshift, who uploaded the following video on their YouTube channel, the Kenworth dump truck runs the quarter mile in 14.1 seconds.

Agreed; that's not something to brag about at a local supercar meet, but keep in mind that we're talking about a dump truck here… Just to get an idea of how fast that is for a vehicle of this type and weight, a few months back, British magazine Autoexpress clocked the BMW 1 Series M Coupe running the 1/4 mile in 13.9 seconds.

Just because you can go faster than other participants at some point in a race, doesn't necessarily mean that you should (at least not always) because you might be in for a very nasty surprise as Matt Messer and his co-driver found out during the 2012 King Of The Hammers UTV race last week.

The second round of the 2012 World Rally Championship after the opening race at Monte Carlo is the only event held on snow, which means that making predictions about the outcome of Rally Sweden is almost impossible.

In tests carried out before the race, some teams experienced freezing temperatures and most expected heavy snowfall during the event. However, during the race, there was much less snow than initially anticipated – and that was a game changer for most teams.

Walter Röhrl is 65 years old but he is not a pensioner yet. The famous German driver began racing when he was 16 years old and won two world rally championships during the most dangerous era of the sport: the 1980s.

One of his most memorable quotes is about the extremely high-powered cars, like the 600HP Audi Quattro S1 that he and his colleagues were driving under minimal safety regulations: “WRC is for boys – Group B was for men”.

More and more automakers are looking to promote their vehicles to a younger and typically affluent crowd through popular racing games.

Today we learn that GM's Team Cadillac Racing has collaborated with iRacing.com, which is one of the most popular online motorsports games, offering players the chance to drive a virtual version of the CTS-V Coupe racer.

Before you go all Newt Gingrich on us, allow us to explain that NASA is an acronym for the National Auto Sport Association. With that of the way, we can now tell you that Nissan and NASA have just announced the creation of an all-new Spec Z racing series for all trim variants of the 350Z from the 2003-2008 model years.

The single make series has the support of Nissan's Motorsports division, which will offer a contingency prize program that rewards the top three finishers at each regional competition weekend with up to $850. The top finishers of the season will also be eligible for a prize of up to $6,500 in cash support.

The bad weather that is currently torturing much of Europe has forced Ferrari to make a last-minute change of plans for its 2012 Formula 1 car launch.

While it was initially scheduled to be revealed at Maranello, and then make its maiden test at the Fiorano circuit, the heavy snow that was more suited to the Ferrari-special Grand Cherokee than an F1 car resulted in the new F2012 to be launched via an online presentation.

Compared to last year’s F150o, which celebrated the 150th anniversary of the Italian Republic, Ferrari's new Formula 1 car has a very unimaginative designation. But names don’t matter that much; after all, the 2011 car had only one win to its credit.

Honda is getting ready to put on its racing suit for the FIA World Touring Car Championship (WTCC), in which it will participate with the new European Civic hatchback.

“We have made a decision to enter into the WTCC with the European Civic," said Honda CEO, Takanobu Ito, on the announcement. "We will develop a totally new engine for this project and we are all excited about starting this new challenge."

The Japanese automaker revealed that its Research and Development division will design a bespoke 1.6-liter turbocharged four-cylinder racing engine with direct-injection in accordance with FIA’s Super 2000 regulations.

Draining all the publicity it can get from the Juke-R's appearance in Dubai where it competed against the Lamborghini Gallardo, Mercedes-Benz SLS AMG and Ferrari 458 Italia supercars on a makeshift track, Nissan has now released official footage from the race.

This is the third video we've seen of Juke-R's win in the past two weeks, so we won't blame you if you've had enough of…Nissan's Groundhog Day. The rest of you can watch the new clip right after the break.
