We can't recall ever hearing this V10 being opened up.
Back in 2004, Ford revealed a retro-themed Cobra Concept car, powered by a 6.4-liter V10 engine. The creation never went into production, with Ford instead opting to announce a modern version of the GT40, followed by the Mustang Shelby GT500. Though it was never put into production, the one and only example of the Cobra Concept still exists, and is currently owned by the engineer who helped built it along with the Dodge Viper and Ford GT.
Being the only one in the world, there are not many videos of the 2004 Cobra Concept on the internet. But YouTuber DtRockstar1 just received a rare ride-along in the car around the M1 Concourse race track outside of Detroit, Michigan. Although the lap is far from race pace, the video gives us an amazing opportunity to hear the car's incredible V10 engine.
The naturally aspirated double-overhead-camshaft V10 produces a whopping 605 horsepower and 501 lb-ft of torque, all going out to the rear wheels through a six-speed transaxle. Based on the insane 7,500 rpm redline and the car's drive ratios, it could theoretically hit 260 mph, breaking 130 mph in third gear! Sadly, the video shows much slower speeds, and the car is reportedly limited electronically to 100 mph anyway.
Even in the short bursts of acceleration on the track, we hear the intoxicating wail of the car's V10. It sounds different than almost every other muscle car we've ever heard. It has a bit of the classic muscle car rumble and exhibits the characteristic shriek of a European V10 like the Lamborghini Gallardo.
It is great to see the owner, Chris Theodore, actually using his Cobra out on a race track and letting someone film the experience. Theodore recently wrote a book about the car, his relationship with Carroll Shelby, and the development process for vehicles like the Viper, Ford GT, Shelby Cobra Concept, Shelby GR1, Shelby GT500. The book, titled 'The Last Shelby Cobra: My times with Carroll Shelby,' is available on Amazon.
