Have a Peek At the Bugatti Chiron's Development Photos

It takes a lot to develop a supercar.

Bugatti will only build 500 Chirons. To get it ready for production, the company put 500,000 kilometers into their prototypes to make sure they'll work at 262 mph in return for your $2.7 million.

All 500 Chirons will be coupés. Bugatti also says that currently, there are no plans for a version with more power. If you're saving up for a Chiron Super Sport, maybe it would be better to settle for 1500 horsepower.

The Chiron has spent more than 300 hours in the wind tunnel. The full scale models go there to ratify those decisions made during the computer simulation. The wind tunnel testing helps to optimize invisible areas in terms of air flow and underbody construction.

With Dallara's driving simulator, the Chiron's parameters could be changed on the fly. This way, Bugatti gains valuable data free of noise in the signal and errors during tool calibration, something that can be an issue with a real car on a track.

To feed those 1500 horses, the Chiron's engine sucks in more than 15,850 gallons of air per minute. The Chiron's powertrain weighs approximately 1388 lbs. The engine itself is almost 970 lbs, despite having its intake tube, the charge air system and the chain housing all made of carbon fiber.

The W16 now employs two-stage turbocharging, meaning that the Chiron moves off the line with only two turbochargers in operation. The other two are only activated at about 3,800 rpm to ensure a linear power delivery.

The hot gases leave the car through a titanium exhaust system ending in six tailpipes, with four routed to the rear and two pointing downwards. The system is equipped with four pre-converters and two main catalytic converters. The total active surface of the six converters is about 230,266 m², otherwise known as more than 30 soccer fields.

Bugatti uses carbon ceramic brake discs made from carbon silicon carbide (CSiC) and says that they'll survive a full stop from 262mph, although they have no idea about the braking distance yet. All they know is that from 186 mph, it's 902 feet (275 m).

Michelin's mission was to make tires that can transfer a maximum torque of up to 3687 ft.-lb. per wheel safely to the road. Above 250mph, each single gram of rubber is exposed to a centrifugal force of 3800 G. Michelin and Bugatti had to go through more than 200 sets of tires during development.

The Chiron has a double-wishbone suspension with electronically controlled shock absorbers that can raise or drop the ride height as well as the compression in five stages. In the standard setting, the Chiron stands just 47.7 inches tall.

Bugatti's carbon fiber tub was engineered with Dallara, who are now also manufacturing it using a sandwich procedure. The production of a monocoque takes four weeks. With this, the Chiron reaches a torsional rigidity of 50,000 Nm per degree and a flexural rigidity of about 0.25 mm per tonne.

What isn't made of titanium, magnesium or aluminum on the Chiron has to be carbon fiber in order to keep its dry weight at 4398 pounds. For the first time, the rear end of the car is also made from carbon fiber, saving 17.6 lbs. right where it matters the most.

In the "Handling" mode, all systems are set for maximum agility, performance and controlled drift moments. The latter function is thanks to the permanent all-wheel drive's electronically controlled rear axle diff lock and the traction control allowing more oversteer, controlled by the ESC.

While the windows roll up automatically at 92mph, if the Chiron is driven faster than 110 mph, the car also switches to "Autobahn" mode. In this case, the chassis is lowered and the steering and shock absorber settings are automatically adjusted for stable handling at higher speeds on the highway.

When a speed of 50 kph is reached, the vehicle automatically switches to the base "EB" mode for comfortable everyday use. There's also "Lift" for when you need maximum clearance.

For those "I wanna go fast" moments, the Chiron does not switch off climate control or any other systems. The driver only gets to see information on the displays that are relevant, navigation or infotainment will fade out. The steering and dampers are adjusted to maximum stability, the chassis height and aerodynamics to maximum speed and that's it. Next stop is at 262 mph, or more if you're a Bugatti test driver. Remember: you only have nine minutes worth of gas. Maybe less.

Bugatti says that the traction control can be switched off completely without making the Chiron undriveable, but if you go there, "you should be an excellent driver."

No doubt.
