Bugatti walks us through the Chiron Pur Sport's testing process

Bugatti is emerging from weeks of lockdown loudly, and sometimes sideways. Its engineers have started testing the Chiron Pur Sport unveiled in March 2020 on the Blister Berg track nestled in Germany's Teutoberg forest. Blister Berg is a private track, so the team only has three days to fine-tune the Pur Sport's chassis, steering, suspension, and gearbox — the latter isn't the same unit that's found in the Chiron because its gear ratios are shorter in order to deliver quicker acceleration. Engineers are also monitoring wear-and-tear items, like the tires, and keeping an eye on the model-specific engine components. That's a lot to cram into three days, especially since Bugatti had to reduce the size of the team it sent to the track in order to comply with the social-distancing measures that remain in effect throughout much of the world. Germany's dense, fairytale-like forest is no exception. Luckily, sensors aren't affected by health-related restrictions, and there's no limit to the number Bugatti can stuff into the two pre-production prototypes tirelessly lapping the Blister Berg track. They're monitoring a variety of parameters, including the exhaust temperature. They're also helping engineers set up the new Sport+ driving mode that relies on gyro-based technology to make the Chiron more eager to drift. Creating this profile requires a tremendous amount of calibration work. Testers download data after each run, analyze it, and make changes if needed. Bugatti told Autoblog the Chiron can already drift, but the new mode makes it a little bit easier.

It wants to show a lesser-known side of its personality. "Bugatti has always proven it can build fast cars in terms of top speed," the company told Autoblog, pointing to cars like the Chiron Super Sport 300+. "However, we also have a history of building cars devoted to agility. This is often forgotten or overshadowed by the incredible top speed feats. We, as did some of our valued customers we talked to about this, felt we should complete the spectrum of performance of the Chiron lineup." Validation testing will continue in the coming months; Bugatti will notably take the Pur Sport to the Nurburgring.

How an 18-cylinder engine and the Porsche 917 shaped the Bugatti Veyron

On the surface, Volkswagen's resurrection of Bugatti looks like one of the many chess-like moves made in its bold quest to expand its portfolio of brands during the late 1990s. In a way, it was; branching out into new segments motivated executives to buy a once-venerated French brand that hadn't made a car in years. On a secondary level, the acquisition allowed one man to fulfill his dream of developing the world's most prestigious car. Bugatti opened its archives to tell the story of how its first 21st-century car, the Veyron, was born.  Ferdinand Karl Piech (1937-2019), a brilliant engineer who rose to the top of the Volkswagen Group during a long and illustrious career, sketched out an 18-cylinder engine in 1997, on the back of an envelope, while riding the bullet train between Tokyo and Nagoya. It consisted of three VR6 cylinder banks separated by 60 degrees and tuned to deliver 555 horsepower. The 6.25-liter engine was naturally aspirated and envisioned for high-end luxury cars -- the kind that would make Mercedes-Benz (who also experimented with an 18-cylinder engine) blush. There was one big problem: Volkswagen Group didn't have a suitable car to put it in. Rolls-Royce would have been an option, but BMW unexpectedly ended up with the name (though not the factory nor the Spirit of Ecstasy) after a bitter bidding war. Although Volkswagen had bagged Bentley, Piech set his mind to buying the dormant Bugatti brand, which belonged to Italian entrepreneur Romano Artioli, after Piech's son gave him a model of a Type 57 SC Atlantic while vacationing in Majorca. He talked Volkswagen's financial department into clearing the funds needed to buy the brand right after he returned to Germany, and the transaction was completed in 1998. With an engine and a name, Piech set the ball rolling. Italidesign's Giorgetto Giugiaro designed the EB118 concept in a matter of months and presented it to the public at the 1998 edition of the Paris Auto Show. It arrived as a front-engined coupe powered by the Austrian engineer's 18-cylinder engine. Several concepts followed: the EB218 shown at the 1999 Geneva Motor Show explored what a Bugatti sedan could look like, the EB18/3 Chiron introduced that same year moved the brand in a sportier direction, and the EB18/4 Veyron brought the idea of a modern-day hypercar much closer to production. It's this design study that received the green light for production.

Bugatti Chiron piloted by Juan Pablo Montoya sets 0-249-0 speed record

Bugatti has a penchant for recalibrating our notion of speed. Quickest, fastest, most powerful, world record — just words. Mere descriptors. To really get a sense of how quick a car like the Chiron is, you need to witness its ferocity in person. Since that's not possible for most of us, seeing it on video is the next best thing. So here's a quick video of a Bugatti Chiron, driven by Indy 500 winner Juan Pablo Montoya, accelerating from 0 to 249 miles per hour (400 kilometers per hour) in just 32.6 seconds. But Bugatti wasn't done. Equally as impressive, Montoya stomped the brakes at 249 mph hard enough to bring the Chiron back down to a halt in just 9.3 additional seconds, aided by the rear spoiler's airbrake functionality. Yep, that's 0-249-0 in 41.96 seconds. From start to finish, Montoya covered 1.93 miles in the Chiron, and it apparently didn't take much effort from the driver. "You didn't need the complex preparations we have to make in racing for the 0-400-0 drive," said Montoya. "With the Chiron, it was all quite easy. Just get in and drive off. Incredible." Incredible is a good word for it. But Bugatti isn't finished setting records with the Chiron. The company has stated its goal of proving the Chiron is the fastest production vehicle ever by beating the Veyron's top-speed record of 267.855 mph. That's planned for 2018, so there's plenty more time for records to fall and would-be challengers to arise. Stay tuned.
