Like children anticipating Christmas morning, we awaited February 19 with hope and trepidation. We had put the 2007 Ford Shelby GT500 on our wish list, and it was scheduled to arrive that day. But we've had more than one hotly anticipated car pulled from our schedule at the last moment, so we made offerings to whatever gods we could find on Wikipedia (sorry for the burnt calf smell in the office, co-workers) and waited for the day. Apparently our karma was in good shape, as a bright red-and-white Shelby GT500 arrived at our offices that day.
With the exceptions of the 2006 BMW M5 and the 2006 BMW M6 in lunatic mode, the 2007 Shelby GT500 is the most powerful car to ever cross the hallowed threshold of the CNET Car Tech garage. The Shelby GT500 is not only a frighteningly potent car (the 500 horsepower from its supercharged V-8 engine was enough to whiten our knuckles even on legal roads), it also is a bookend to a generation of muscle cars starting with its namesake, the GT500 that made its debut 40 years ago.
Sporting the signature Le Mans stripes down the center of its body and a rash of SVT logos denoting its heritage in Ford's Special Vehicle Team, our test car arrived to much fanfare. Despite its obvious DNA, the 2007 incarnation of the GT500 does not want to be known as a Mustang: nowhere on its body is there any reference to Ford's iconic pony car. Neither is it classified as a Cobra, despite the presence of plenty of Shelby-inspired Cobra logos on its steering wheel, seats, and exterior panels. All the same, after a week of driving it, we can confirm without reservation that this car is definitely some kind of animal.
Test the tech: Engine versus stereo
Our usual focus when conducting our tech tests of a review car is to think of an entertaining real-world application for one of its onboard gadgets. With the Shelby GT500 we were somewhat confined in our choice. The car's cabin technology is limited to its standard 500-watt (peak) Shaker 500 stereo (a 1,000-watt upgrade is an available option) and a couple of instrument-cluster gimmicks (see the In the cabin section below for details). The other main technology feature of the Shelby is its engine: a 500-horsepower 5.4-liter V-8 block with four-valve cylinder heads sourced from the Ford GT supercar assisted by a Roots type Eaton supercharger.
For our tech test we decided to pit the stereo against the engine in a sound test. Which would be louder, the 500-watt stereo or the 500-horspower engine? Armed with a sound meter, we took the Shelby GT500 to an unused wharf in San Francisco to find out. The stereo was first up, and we feared for our eardrums as we killed the engine and slotted a CD into the Shelby's six-disc in-dash changer. Having selected JXL's remix of Elvis Presley's "A Little Less Conversation" as our test tune, we cranked up the volume to "max." After a couple of minutes of cacophonous discomfort holding the sound meter in the center of the cabin, we got a maximum reading of 103 dB. If you're wondering how loud that is, then we can assure you, IT'S PRETTY DARN LOUD!
Next, it was the V-8 engine's turn to make some noise. As to not to break the Shelby without actually driving it, we decided that we would take the volume reading with the engine turning at 5,000rpm. Wayne selflessly volunteered to sit in the driver's seat stamping on the gas pedal with the car in neutral, while I held the sound meter under the hood to take a sound reading. As the engine speed rose through 3,000 and 4,000 rpm, it was clear the sound competition was going to be a close contest. With the engine at 5,000rpm and our ears ringing, we ceased the revving. The sound meter was reading 108dB--5dB more than the stereo. We had our winner.
In keeping with the whole character of the 2007 Shelby GT500, the engine had trumped the onboard tech. Mustang fans wouldn't have had it any other way.
In the cabin
Those looking for comfort and luxury in a sports car should stop reading now, as the interior of the 2007 Shelby GT500 is a mobile version of old Mother Hubbard's cupboard. Aside from the prominent Cobra logo in the center of the steering wheel, the view from the driver's seat is a dreary one. A sea of dull black-and-gray plastic surrounds the front occupants on all sides, the most noteworthy features being two gaping cup holders and a large, black plastic parking brake in the center console. The central stack is hardly more inspiring: indifferently fitted gray panels do a poor job of representing carbon fiber, and the black plastic stereo head unit with its single-line monochrome LCD is a relic of the predigital age. Bulky black plastic surrounds for the speakers complete the Spartan interior ensemble.
Despite the car's primitive interior appointments, the cabin does offer some surprising tech features. The Shelby's Shaker 500 stereo is more sophisticated than its 1980s appearance suggests. It features a six-disc in-dash changer with the ability to play MP3 discs and portable MP3 players via a generic auxiliary-input jack in the center console. Our test car also was equipped with the option of Sirius Satellite Radio. For MP3 discs, the stereo's LCD displays ID3 tag information for song, artist, and album, which can be cycled through by pressing the TXT button. While the display only shows 12 characters at a time, longer tags can be read in full by pressing the seek button. Similar to the stereo in the 2007 Ford Expedition, the Shelby's stereo enables drivers to choose between folder and track mode when playing MP3 discs.
