2017 Bugatti Chiron:
The $2.6-Million, 1500-hp, 261-mph Image Booster
With the Bugatti Veyron’s top-speed records, a price tag over $1 million, and distinctive melted-scoop-of-ice-cream styling, it was an instant rolling superlative when it debuted in 2005. Its successor, the new Chiron, is even more of a record- and headline-grabbing show pony. Is it faster? A 310-mph (500 km/h) speedometer and Bugatti’s claim that it’ll do 261 mph say it is.

Between Bugatti’s braggadocio and posturing, there are real improvements to the Veyron’s formula. Does it matter that, if every strand of carbon fiber in its new central tub were laid end to end, they’d “stretch nine times the distance between the earth and the moon”? No, and we pity the Bugatti employee charged with checking the arithmetic on that factoid. But it is indicative of a real effort to reduce—or at least hold the line on—the Chiron’s weight relative to that of the somewhat pudgy Veyron. All of that carbon fiber—the body panels also are made of the stuff—helps keep the Chiron right around the same weight as the 4486-pound Veyron, despite being 3.2 inches longer, 1.6 inches wider, and 0.3 inch taller. Bugatti further claims that the Chiron’s structure is as stiff as those underpinning LMP1 racing prototypes.
At the risk of sounding beguiled, the styling of the Chiron is notably more fetching than that of the Veyron. The C-shaped curve carved into each side of the body recalls Bugatti’s 1930s-era art-deco masterpieces, the Type 57 Atlantic and Atalante, as does the spear running down the car’s spine. The all-mesh tail appears to belong to a different car, but the surfaces bending and flowing beyond it are nearly beautiful. Up front, Bugatti’s horseshoe-shaped grille remains—stamped with a badge rendered from five ounces of silver—and is flanked by quad-LED headlights. Moving aerodynamic elements range from a hydraulically operated diffuser, front splitters, and a four-position rear spoiler/wing that can sit flush with the rear bodywork, extend slightly (the setting for top-speed runs), fully extend, or fully extend and tilt in its air-brake setting. The underbody is totally smooth save for NACA ducts that gulp air for cooling the engine, the transaxle, and the rear brakes.
Exhaust is routed from the turbos to a new titanium exhaust that Bugatti claims weighs 44 pounds, which is “extremely light compared with similar [16-cylinder] units.” Perhaps the automaker is referring to the chrome stacks on semi trucks, because it also proudly describes two of the catalytic converters as being “six times as large as [those] fitted to a medium-sized car” and boasts that the total exhaust-scrubbing area of all six catalytic converters is greater than that of 30 soccer fields. This should give you some idea of the level of emissions produced by an 8.0-liter 16-cylinder engine.
As in the Veyron, torque is routed to all four wheels via a seven-speed dual-clutch automatic transmission. Bugatti claims the clutches are the “largest, highest-performing” such components ever fitted to a car. They’d better be if they’re going to stand up to the 8.0-liter’s 1180 lb-ft of torque during sub-2.5-second rips to 62 mph. Also like the Veyron, the Chiron is a rolling heat-exchanger farm, with more than 13 gallons of coolant circulating through two separate cooling loops. The first loop holds 3.2 gallons of liquid and cools the turbochargers’ intercoolers; the larger loop services the engine and pumps 9.8 gallons of coolant through its veins into three radiators. There also are heat exchangers for the engine, transmission, rear-differential, and hydraulic oils, as well as those needed for cabin heat and air conditioning.
Bugatti claims the Chiron can pull 1.50 g’s in lateral acceleration; this probably has more to do with the car’s massive 20-inch 285/30 front and 21-inch 355/25 rear bespoke Michelin tires than outstanding chassis tuning or light weight. Those tires, by the way, also are said to boast a larger contact patch than the Veyron’s and will apparently be “easier to install and allow lower operating expenses.” Considering how the Veyron Super Sport’s tires cost $42,000 per set and required the replacement of all four wheels after three tire swaps ($69K), the change is welcome. Because the rear air brake alone won’t quickly shave big speed, the Chiron uses carbon-ceramic brake rotors that are all 0.8-inch larger in diameter and 0.1-inch thicker; the front rotors are 16.5 inches across and the rears are 15.7. The front brake calipers employ eight pistons, while the rears have six.
The Chiron’s interior has been completely redesigned and seems to have been given nearly as much thought as figuring out how to make a 4400-pound chunk of carbon fiber and metal hurtle through the atmosphere at more than 200 mph. The aesthetic is spare yet clearly upscale. A glowing rib echoing the external “spine” sweeps down the middle of the cabin and is said to be “the longest light conductor used in the automobile industry.” A waterfall of simple aluminum dials for the climate system pours down a gleaming aluminum strip supported by carbon-fiber ribbing, while infotainment and navigation duties are handled by a pair of screens flanking the analog speedometer. The entire gauge pod, in fact, is an incredible piece of sculpture that is milled from billet aluminum.

Awestruck yet? There’s little doubt that the Chiron trumps even the mighty Veyron in the jaw-slackening department. The Chiron is undoubtedly an engineering triumph and the pinnacle of immoderation; the masses should be properly enthralled. Most critically, so should those with the considerable means to purchase one.
