##2017 Eau Rouge prototype
After the overwhelming success with the Diabolica. Which actually meant that the only car in existence was not crashed during it’s public appearances, Kraft Haus has received a number of offers on the one-off. Refusing to even name the price, let alone sell the car has made the ultimate KHT to be very desired, but more importantly is has clearly marked a target niche that could have been filled. Not backing out of the idea of the Diabolica being the one off not for sale, Kraft Haus has started work on a car that would take it’s place.
The need for a new chassis did not arise, since Diabolica used a slightly modified Sepang chassis. A well tested and proven carbon fiber tub covered with a carbon fiber body. Most of the Diabolica’s aero research has been put to good use, as well as information gained while developing the super lightweight Mistral and Augusta. Resulting in a car in sync with the KHT design philosophy while bringing some new ideas to the table.
The main focus of the car was it’s weight, with battle for each kilogram resulting in an extremely spartan interior, lacking any form of in car entertainment, it included basic controls and basic safety features, and the weight saving did not stop there. The brakes, the chassis, gearbox, and even the engine were built shedding every extra kilogram off the final weight.
The engine however was a challenge, but thankfully, it was in development for a few years, as the contract with Karion for the 6.3 liter v8’s has expired and was not renewed. A new partnership has been established with the automotive giant Saminda, who helped develop the DOHC heads along with VVT, Engine control unit and the direct injection system. VVL idea was actually mid development, but scrapped due to weight saving ideas. The engine block was now a custom order magnesium unit, outsourced to JSC. The result was a 7 liter magnesium v8, DOHC with VVT and direct injection, helped with a pair of custom turbochargers and a lightweight titanium alloy exhaust system, which also has shed 11kg from prototype to production version. The power output of the initial engine version reached 1000hp, and 1022 nm, with only 0.7 bar of boost, very much eliminating turbo lag.
A new custom gearbox has been developed, being an H pattern 6 speed, also, for reasons of it being lighter than a sequential 7 speed. The car used the same electronic rear differential as the Diabolica, and the same pushrod suspension setup. All this weighing in at 1135kg, running on racing slicks the car managed 0-100 in 2.5 seconds flat, and topped out at 403kph, while the aero provided downforce to be able to take corners at 1.54g and braking at 26.64m.
The quality of the car required serious precission work, meaning the building process was to be painfully slow. KHT predicts it can build up to 4 cars per year at a price of about $500,000
First appearance of the car is scheduled at a hypercar hype 2017 showdown, running against numerous opponents, including Gryphon Gear, who helped develop the car Eau Rouge was based on, where KHT had to prove they can stand in the hypercar market on their own.
