If you haven't heard of Tuthill Porsche yet, don't feel like a bad 911 enthusiast. The British company typically focuses on rally-specific upgrades, so it's not always talked about in the mainstream media. However, this niche outfit knows its stuff and has assisted on Ken Block's race car and even Singer's All-Terrain Competition Study (ACS). But now it's come to take a slice of the pie that it helped bake.

At Monterey Car Week last weekend, Tuthill rocked up with a new restomod based on the 930-generation Porsche 911 Carrera. Surely that particular pie has too many people with their fingers in it already, right? Well, Tuthill is doing things differently with a new series of vehicles that starts here: the 911K.

For a start, its car is astonishingly light at just 1,874 pounds - with fluids! If that's not enough, it has a 3.1-liter engine that revs all the way to 11,000 rpm. Sumptuous!

Tuthill Porsche has not revealed how much power the engine produces but has said that the short-stroke four-valve engine has a carbon fiber intake plenum and is connected to a magnesium six-speed 915 K gearbox as found on the later 964 and 993 iterations of the 911.

For stiffness, the gearbox has a cross-member made of carbon, too, while a titanium roll cage in the rear barely adds to the weight and comprehensively enhances safety and rigidity. Other titanium parts include the torsion bars and anti-roll bars.

The company has also revealed that the car features a proprietary competition pedal box and wiring harness, as well as a bespoke oil tank and a cooling system with an electric fan that is mounted under the front of the car.

Sticking with technical details, the Fuchs-style wheels are made of carbon fiber and measure 15x7 inches in front with the same diameter and nine inches of width for the rear rollers. These conceal carbon-ceramic discs while bespoke calipers and two-way rally dampers contribute to road-holding proficiency. Sure, bigger wheels and bigger brakes would have been possible, but do you need ridiculous stopping power (and outrageous horsepower) in a car this light? No, and they'd look worse anyway.

To achieve that astonishing wet weight, the roof, doors, rear quarter panels, front wings, bumpers, hood, engine lid, rear bulkhead, and even seat wells are constructed of carbon fiber. The engine lid badge is even made of titanium, and the Porsche crest is hand-painted.

Inside, more carbon can be found in the bespoke seats, the RS steering wheel, the hydraulic e-brake, the dash panel, and the door cards. The gear knob is made of titanium, and the upholstery is made from Ultra Fabric and Ventile, both of which are resilient yet sustainable materials.

The company's director, Richard Tuthill, says that this was a passion project: "There are so many great people in the world building amazing Porsche 911s, it's sometimes quite daunting to roll your sleeves up and get stuck in. That said, my experience over the last few years, when combined with an extremely enthusiastic and supportive friend and client, was enough."

We don't know what the 911K costs or how many will be made, but a full carbon body, an ear-splitting atmospheric engine, and classic 911 looks that have not been altered much sounds like a recipe for greatness. This car was built for drivers and looks the part, and based on how it sounded at The Quail, we think it's already destined for success.
