In a dazzling on-screen debut, Collecting Cars’ latest film offers an inside look at the concept, creation, and electrifying performance of the sensational Tuthill Porsche 911K.
From the first sketches to the final roar of the engine, viewers are treated to a behind-the-scenes journey that reveals just what makes this bespoke sports car so special.
At the heart of the Tuthill 911K is a relentless focus on lightness. Engineers have harnessed the strength and featherweight properties of carbon fibre throughout the car’s construction, trimming every possible gram to achieve a remarkably low curb weight. The result is a vehicle that feels almost alive in its agility and responsiveness, offering a purity of driving experience rarely found in modern sports cars.
Power comes from a specially tuned 3.1-litre flat-six engine, engineered to deliver its best at stratospheric revs—up to a dizzying 11,000 rpm. This high-strung powerplant churns out approximately 350bhp, which, when paired with the car’s minimal mass, creates an astonishing power-to-weight ratio. The effect is immediate: blistering acceleration, razor-sharp handling, and a driving sensation that’s as close to telepathic as it gets.
The soundtrack alone is enough to quicken the pulse, with the engine’s wail building to a crescendo as the tachometer needle swings towards its lofty redline. Richard Tuthill, the mastermind behind the project, describes the 911K’s character as akin to “a four-wheeled motorbike”—a machine that demands engagement and rewards skill with pure, unadulterated thrills.
While recent iterations of the Porsche 911 have grown heavier, with some models now weighing in at 1,700kg, the Tuthill 911K tips the scales at just 846kg—less than half the weight of its modern counterparts. This dramatic reduction is a testament to Tuthill’s obsessive attention to detail and commitment to the ethos of lightweight performance.
But the story doesn’t end there. Richard Tuthill has hinted that, with even more extreme weight-saving measures, the 911K could potentially dip below the 800kg mark. This tantalising prospect suggests that the boundaries of what’s possible in a lightweight Porsche are still being pushed, promising an exciting future for enthusiasts who crave the ultimate in driving purity.
With its combination of cutting-edge materials, race-bred engineering, and a driving experience that harks back to the golden age of sports cars, the Tuthill 911K is more than just a car—it’s a statement. A statement that, in the right hands, less really can be more. For those who live for the thrill of the drive, this is one Porsche that’s impossible to ignore.
