From the beginning, the Nissan GT-R's performance figures seemed too good to be true. Weighing in at over 3,800 pounds and packing a claimed 480 hp, the 3.5-second sprint to 60 and 11.8-second quarter-mile time just didn't add up. And then the tests began...

Buff books and online outlets began publishing 0-60 runs between 3.2 and 3.4 seconds, and quarter-mile times began dropping quicker than a co-ed's IQ on a nitrous binge. CARandDRIVER.com discovered a similar discrepancy between five different GT-Rs and finally decided to get some time on the dyno to get some real-world numbers.

Click above to view video of the AeroMotrions wing in action

Earlier this week we introduced you to the AeroMotions downforce splitting rear spoiler, a wing that's split in two and uses an onboard computer to selectively adjust the pitch of each wing section to provide the maximum amount of traction for any given situation. At the time all we had was a single picture from the spoiler's debut at an autocrossing event in California, but the company has since released video of said autocrossing showing the wing in action. Watching the video after the jump, you can clearly see how this thing works. Turn left and the driver-side part of the wing flips up to increase downforce and keep the inside rear wheel planted. Turn right and the opposite happens. Floor the car in a straight line and both halves of the wing level out. The amazing thing is how fast each section of the wing reacts, as its constantly adjusting the angles in real time. Follow the jump to check it out for yourself. Thanks for the tip, Vince!

Alex Roy, currently locked in an M5 with our own Damon Lavric, recently got a video tour of a rather nifty Audi R8 owned by someone who insists he remain nameless. Codenamed Blackbird, the coupe is stuffed with enough gadgets to be a testbed for NASA's shuttle replacement, but don't for a second think the interior resembles a jungle of wires, screens and antennae: all the electronic gear is seamlessly integrated in a most impressive way. A sample of the wares in the blacked out supercar with the gunmetal gray blade include four GPS units, two radar detectors, police scanner, CB radio, kill switch for all rear lights, high-speed broadband Internet with Wi-Fi running on a tablet PC, power ports, takedown lights, a remote-controlled exhaust bypass valve, and -- get this -- a liquid-cooled infrasonic wave pulse generator. Apparently, you don't want to stand by that last item if you wish to have children. Follow the jump for the whole story in moving pictures. Thanks for the tip, Mike!

Since the Mazda3 hit the streets in 2004, it's proven to be a very strong contender in the small car segment. The compact sedan and hatch has been winning customers over with great styling, athletic ride characteristics, and equipment that typically isn't found in small cars. Its rich mix of standard features and options has helped keep transaction prices high, which will be very important as the self-proclaimed Zoom-Zoom automaker looks to downsize its lineup and make as much money as possible from every sale.

Mazda will now execute the Mazda3 strategy across its entire line to boost profits while giving customers the standard features they crave. For example, the all-new 2009 Mazda6 will be equipped with disc brakes at all four corners in every trim level while some of the competition continues to use rear drum brakes on their base models. Mazda has already proven that adding standard content can raise transaction prices while at the same time increasing sales, now the Ford-controlled automaker needs to prove that it can accomplish the same feat across its lineup. If Mazda makes all of its vehicles as competent as the Mazda3, that shouldn't be a problem.

The faster a car goes, the more downforce its various wings, spoilers and splitters can produce. There's always a trade-off though, as the byproduct of downforce is more drag, which reduces a car's top speed. Supercars like the Bugatti Veyron use active aerodynamics to produce the right amount of downforce for a specific situation like twisty road courses or high-speed runs, but cars like the Veyron are out of reach for most. Enter AeroMotions, a company that promises its rear wing assembly will provide the perfect amount of downforce at all times. The carbon fiber wing is split into two sections, each one moving independently of one another to offer just the right amount of traction. An on-board computer constantly monitors acceleration, braking and lateral acceleration so it can actively change the pitch of the wing's sections in real-time as the car is being driven, effectively giving more or less downforce to whichever side of the car needs it most. AeroMotions' wing is currently undergoing testing, and one of our readers happened to witness it in action in California and was impressed. If anyone's got video of the wing in action, we've got popcorn and are waiting. Thanks for the tip, Vince!

FasTrak is an "electronic toll collection system" used in California. Once you set up an account, you get a transponder that simply debits your account balance whenever you pass through a toll booth. The system uses RFID technology to broadcast your account information to the toll booth receivers. According to Hack A Day, the system is anything but secure.

Among other problems, an attendee at the Black Hat 2008 conference in Las Vegas found that because the in-car transponders don't require any authentication, anyone with an RFID reader can get the unique ID from any car and then use that in their own transponder. Not only that, but you could also force any other transponder to take on a new ID because of the system's open over-the-air upgrading system.

To change the system would require legislative action since it's all defined by California laws, so Californians shouldn't expect a quick fix. Until -- and if -- a fix comes, we suppose the best that can be done is to make sure you scrutinize your FasTrak bill. And keep an eye out for guys kitted out like Star Trek yeomen wandering the park-and-ride commuter lots... Thanks for the tip, fabienne!

Click above for high-res gallery of the AMG S63

There was a time when what we might call super-sedans were largely the province of a dedicated cadre of aftermarket tuners. Companies like Brabus, Alpina and, of course, AMG would generally start with mid-sized German sedans and transform them into something truly special. AMG in particular came to the forefront in 1987 after two decades of building special Mercs when they unleashed the Hammer. They had been building cars for two decades already, but the Hammer took things to a new level by installing a 5.6L V8 from the 560SEC coupe modified with twin-cam four valve heads into the mid-size 300E sedan. With that car, AMG set off an arms race that continues to this day. The tuners are still out there but AMG was eventually brought in from the cold when it was bought by Mercedes-Benz. Today AMG produces high performance versions of almost all Mercedes models and standing near the pinnacle of the lineup is the S63 sedan. Find out what the AMG S63 is like to live with after the jump.

When a BMW 335i owner in Munich became bored with his black coupe, he hired a team to wrap it in white tape. Two days later, he drove home in his refreshed "Alpine White" coupe (with an M3-appearing black roof). No, it's not normal tape. It's a special 3M wrap, and the process is known as "foiling." Apparently, the German military has been using the process (with an olive drab tape) for some time now. Likewise, the process is popular with race teams and taxi companies. Available in countless colors, the tape itself is thick enough to protect the paint from minor chips and nicks, and it can be left adhered to the surface for 3-4 years without damage (!). Adhesion isn't a problem either, as the tape can even withstand an automatic car wash without peeling off. Thanks for the tip Frank.

Remember in the first Crocodile Dundee movie when he gets mugged in New York City and Sue says "He's got a knife," and Dundee says, "That's not a knife, this is a knife," and then he pulls out a beast-killing monstrosity of a blade? Well, that's what the folks at Titan Tire are saying right now about every other -- smaller -- tire in the world.

Titan has made a 63-inch rubber behemoth for use on trucks in Canada's oil sands. The stats on these rubber donuts is impressive: the 59/80R63 is the biggest production tire in the world, standing over fourteen feet tall and weighing 12,500 pounds with a load rating of 101 metric tons. It makes Titan a very appropriate name for the company, as we learned from another movie, Remember the Titans, that in Greek mythology the Titans were greater even than the gods. Now we can only hope this development will make the price of oil drop another ten dollars...

One day after spotting the "inexpensive" auto performance measurement tool Dynolicious for the iPhone, we've found another, and it's much cheaper. Liberty For One has released its own automotive measurement tool called g-tac, and its going for just $4.99. For less than half the cost of the Dynolicious tool, you get times and trap speed for the quarter mile, as well as times for 0-60 and 60-0. The g-tac utilizes the iPhone's (and iPod Touch's) accelerometer to determine velocity, so the phone doesn't have to be plugged into the car. The tool also graphs out your last three runs so you can hone your launch technique over time.

g-tac's feature list doesn't appear to have the robustness of the Dynolicious app, which also features metrics for Lateral Gs and horsepower, and there isn't much documentation to detail what g-tac can actually do. The early reviews aren't so hot either, as the first seven purchasers have averaged a rating of just 2.5 stars compared to the four star rating for the Dyonlicious app. Since cheaper doesn't typically mean better, we intend to test both apps against an even more expensive hardware unit, and we'll let you know if either iPhone app is worth your hard earned digital dollars.
