WHERE IT’S BUILT Bugatti Chiron

Only in a jaw-dropping facility can you build the world’s most incredible car. And whatever you do, keep it down

O N AVERAGE, Toyota churns out a Corolla every 23 seconds. An 86? Every seven-and-ahalf minutes. Raise the stakes with Honda’s NSX, capable of a hybrid-power assisted 308km/h, and you’re looking at a car rolling off the assembly line once every three hours.

So what about the car that could shortly become, offi cially, the world’s fastest production car?

Should the newly released Bugatti Chiron, the sequel to the groundbreaking Veyron, smash the top-speed record, the real achievement is that it will still boast luxury to attract the fussiest of Sultans – 500 of them, hopes Bugatti.

As the fi rst of these cruise missiles are bolted together, Bugatti’s opened the doors to its ovalshaped building in Molsheim, France, where each Chiron will be delicately and precisely crafted. It’s also where the Veyron was once made – and is the complete opposite of a mega factory. For a car so fast, assembly is oh-so-slow, 70 rolling out the factory each year without a single robot in sight. Just a McDonald’s. Directly over the road.

Instead, while 20 people populate the Chiron assembly line, it doesn’t really follow a line at all. The space within Molsheim’s walls presents itself more like a Formula One workshop in both layout and organisation. Giving staff space to assemble a Chiron from a total of 1800 parts.

With Molsheim’s fl oorspace measuring slightly more than 1000 square metres, or fi ve tennis courts, it’s a bit cramped for manufacturing. Instead, much of the Chiron arrives from elsewhere. Items like the engine (VW), gearbox (Ricardo), chassis (Dallara), brakes (AP), tyres (Michelin), all arrive in fi nished states, while the interior and body panels are only ordered once a customer secures their production slot with a whopping AUD$300K deposit.

However, no-one opens a box until one man gives the nod. Each project waits on Christophe Piochon, Bugatti’s production and logistics boss, before getting the go-ahead. He’s also the watchful eye that ensures the process runs cylinder smooth for the customers who’ll eventually fork out 2.4 million euro (AUD$3.61m) for the fi nished product.

Appropriately for an 1103kW car, assembly starts with the engine. It’s the fi rst component workers prepare, but each quad-turbo 8.0-litre W16 is hand built in a VW engine plant in Salzgitter, Germany, over six days. After, it’s sent 560km to the Molsheim facility, where it’ll be mated to a Ricardo seven-speed dual clutch ’box able to handle the huge 1600Nm.

The engine’s construction, however, can’t compare

There’s no robot in sight. Just a McDonald’s, over the road

With beefed up electricity cables,

to the sheer manpower involved in making the carbon-fi bre chassis. Italian company Dallara has 50 people make a monocoque by hand, layering 150 carbon-fi bre sheets onto a mould, before baking and milling the unit into its ready state. This takes four weeks but saves on shipping costs. Once fi nished the entire monocoque weighs as much as a four-cylinder engine. Or less than some humans.

Back at Molsheim, the Chiron physically starts to take shape as these two parts are married together.

Three people climb over the chassis and engine, bolting them together with precision. And they take their time, about a week, because a loose bolt here might mean a big wobble on the autobahn. During this process each bolt is, of course, carefully and individually torqued.

Workers will use the precise torque wrench 1068 times all up, and while more than 1800 bolts are involved in making each car, only 14 titanium items aerodynamics, power, or grip. Because even though it produces 1103kW, enough to break the fi rst dyno it used during development, it’s actually shedding twice as much energy in heat – enough to power an average home for eight weeks. And Bugatti would know as, with so much grunt fl owing, the in-house dyno was connected to the local electricity grid where it feeds in excess electricity. For real.

The real reason each freshly-minted Chiron is plonked on the dyno, however, is to crank up to 200km/h for the fi rst time. But don’t think this is the same roller you’ll fi nd at your monthly car show.

Special adapters that look like robot arms hold the Chiron down on its rollers, keeping the chassis from lunging off as it fl exes its 1600Nm. A series of system checks are then run over a simulated 60km.

But while this sort of pilot run would be enough for some manufacturers, Bugatti wouldn’t dream of signing off the drivetrain at this point. No, a blast clamp the driver’s monocoque to the drivetrain assembly, each a featherweight 34 grams. They’re up to the task, though, as proven by the Chiron’s otherworldly torsional stiffness, its body rigidity matching a Porsche Le Mans prototype. Two tonnes on the Chiron’s right front wheel would jack its left rear wheel by only a single degree.

While all this is going on, huge cooling hoses run to and from the front radiators, down the car’s sides.

Some are as big as a fi re brigade’s hose. In total there are 10 radiators hidden in the Chiron’s curves, powered by three water pumps.

Filling them is the next step after the chassis and engine marriage. And requires fi tting wheels before rolling a Chiron over to the dyno. Once full of coolant – 37L of it – the team can fi nally fi re up the engine.

Cooling’s a hot issue for engineers, just as much as across an airport and the autobahn are in order to prove each car can handle its grunt in the real world.

And still, there’s more. Before venturing out the gates, it needs to be armed with its outer shell and resulting downforce. Almost a whole working week is taken to fi t the carbon-fi bre body panels, but Bugatti still doesn’t want to leave much to chance. Each example has to also survive 30 minutes in monsoon rain conditions before fi tting the interior pieces. If it remains water tight, the cabin bits are then green lighted for fi tting. Which takes almost another week.

Of course, sending the Chiron out on public roads with only a prayer would be madness. With a threeweek painting process already invested into the body panels (they’re pre-fi tted, painted, and inspected off site before arrival) a day is set aside to wrap each car with a thick clear fi lm. Its undertray and wheels, too,

Not So Fast

500km/h? We don’t know yet

YOU WOULD have noticed we didn’t call the Bugatti the world’s fastest production car. That’s because it isn’t... yet. The Chiron’s been limited to 420km/h for road use, lower than the Veyron Super Sport’s 431km/h, but company CEO Wolfgang Durheimer’s adamant it can travel much faster. How fast? Well that’s the next mystery because Durheimer revealed the official test with the Guinness Book of World Records won’t be conducted until 2018.

He promises it will beat the Super Sport, though, and there is the slight fact the Chiron’s speedo winds out to 500km/h. Of course, however fast it goes, you can bet it’ll eventually go even faster. It’s understood we’ll see variants equivalent to the Vitesse and Super Sport in its lifetime. We doubt many owners will ever see such speeds, however, lower volume rivals like Hennessey with its Venom GT will be tapping their feet for Bugatti to back up its claims.

are swapped for damageable test-run items.

Now it’s up to a test driver, He Who Shall Never Complain About Anything, to see if each Chiron drives as it should. They start off for an airport 30 minutes south of Molsheim, trying their best to obey the speed limit until they can unleash the Chiron at speeds in excess of 250km/h. Monk-like restraint is again exercised for the trip back on the autobahn, the return leg of which is designed to make sure the car can cool itself back down.

Should the hypercar fulfi l its performance brief, the original wheels and under tray are installed. Bugs are then wiped off and two days is spent cleaning the car.

After that, it’s a date with a keen eye in the facility’s light tunnel. Here a white-gloved worker inspects the Chiron in infi nite detail, looking for any and every imperfection. Some things are fi xed in a day, others take a month if a replacement item needs to be ordered in. And once the inspector is happy, the big guns are called in.

Christophe Piochon invites the company’s head of sales and they begin an extensive look over. After all, they’re the ones handing the keys to customers like, reportedly, Floyd Mayweather. And you don’t want to get on the wrong side of a fi ve-division world champion boxer.

Some also elect to personally visit their car during production. Apparently Cristiano Ronaldo, of soccer (or football) fame, and one of the fi rst deliveries, lent a hand during his car’s assembly. Customers are freely invited to help build their own car if they wish. Under presumably very close supervision...

Got more cash than you know what to do with, and Bugatti will gladly take it off you by way of customising your Chiron – provided any changes meet standards and won’t affect the car’s performance. And when carbon-fi bre tint (where you can basically see the carbon weave through the paint) costs more than AUD$350K, you can imagine most Chirons will end up tallying a whole lot more than the base 2.4m euro.

By the time a car’s completed, anywhere between six to nine months has passed since it was fi rst ordered, with a more concrete timeline depending on how tick-happy the customer is with options. Overall two months are spent building a car in Molsheim, revealing how much longer goes into sourcing and preparing its many ingredients.

Of course, if it wanted to save time, VW could cut its reliance on suppliers by bringing production in-house and bump up the volume. But such an investment wouldn’t be justifi ed by the Chiron’s small run, and customers are paying for exclusivity. And with half of its allocation already accounted for, that’s exactly how it’s stacking up.

What’s obvious, though, is Bugatti allows itself time to get things right. Yet with as many as 12 Chirons being built at Molsheim at a time, it still needs to apply Germanic levels of planning and detail. We’re sure a lot of customers aren’t used to waiting for things they’ve paid for. But if we were inching towards 400km/h on the autobahn, we’d want to know Bugatti didn’t rush a thing when building its Chiron. And, thankfully, now we do. M
