Leblanc Mirabeau: world's quickest production car

A novel and vital part of the CCR engine is the minimum drag Koenigsegg DFCC-system (Dynamic Flow Catalytic Converter), nicknamed the “Rocket Cat”, which ensures minimal exhaust back pressure despite allowing for a highly efficient filtering of emission gases. This technological feat cannot be overstated; no competitor has come close of creating an engine with a power output of over 800 horsepower (apart from the Bugatti), and keep exhaust gas emissions below certifiable levels.

Similarly, Leblanc only states that the Mirabeau has a six speed sequential gearbox, so we’re presuming it is the same Cima transaxle gearbox specially designed for Koenigsegg. This 6-speed manual/sequential gearbox is probably the strongest and most reliable transaxle gearbox ever built for a mid-engine car. Italian manufacturer Cima has utilised its vast experience in building custom racing gearboxes in the construction of Koenigsegg's transmission system. It is equipped with an internal oil pump for reliable lubrication and a large external Setrab air-to-oil cooler, which is necessary due to the immense force of the engine. It also features an advanced torque sensitive limited slip differential. The default set final gear ratio is calculated to propel the CCR close to 400 km/h at 7300 rpm.

The gearbox is operated manually via the Koenigsegg developed shift mechanism, a clockwork piece of fine mechanics, which allows the gear lever to be mounted on a ball in a socket. This practical and aesthetically attractive device provides accurate feedback to the operator and also alleviates the otherwise necessary gate solution. The mechanism is designed for compactness and low weight, and it is easily adjustable to driver preferences. It also incorporates an electronic anti-theft device. The dual plate clutch is oil-cooled and electronically operated on the Koenigsegg though there’s obviously more of the story to come as the Mirabeau is offered with Semiautomatic Gear Shifting as a 52,000 Euro optional extra.

That’s on top of the 478,000 euro (plus value added tax) price of the Mirabeau.

Now here’s the cruncher – the total car weighs in at just 812 kg. That might not mean much if you’re not unhealthily familiar with supercar specifications, so we’ll help with some perspective. That’s less than two thirds of the weight of a Porsche Carrera GT or Saleen S7.

It’s a whopping 570kg lighter than a Ferrari Enzo and half the weight of the Bugatti Veyron.

No doubt if you want to have a CCR motor fitted to your Mirabeau it can be accomplished with the right exchange of currency, the only thing you’re not likely to get is a certificate that says it’s standard, something that will be no doubt jealously guarded by Koenigsegg until the Bugatti arrives at which point they might give the car its pedigree in writing.

This is all speculation mind you, as Wysstec are not exactly being very forthcoming about the Mirabeau. With their elite clientele, they don’t need to be.
