Bugatti Hypercar Timeline: From Veyron and Chiron to the Tourbillon V16

The W16 is arguably the most famous engine badge in modern automotive history: eight cylinders on each bank arranged in a “W” shape, four turbochargers, and displacement that stayed at 8.0 litres from the 2005 Veyron all the way through the final Chiron Super Sport variants nearly twenty years later. Bugatti kept extracting more from it — 1,001 PS, then 1,200 PS, then 1,500 PS — but that same longevity is part of why it eventually had to go.

Emissions and efficiency regulation tightened steadily across every major market Bugatti sells into, and a naturally aspirated, electrically assisted engine is a more credible path to compliance over the coming decade than a fifth or sixth generation of an already highly stressed quad-turbo W16. Electrification also isn’t just a compliance box for Bugatti’s new ownership structure: Bugatti Rimac exists specifically because Rimac Group’s hybrid and EV powertrain expertise was judged more valuable to Bugatti’s future than another round of turbocharger development.

There were engineering limits too. The W16’s packaging — sixteen cylinders, four turbos, and the plumbing and cooling that extreme boost requires — had been optimized about as far as it could go without a clean-sheet redesign. Weight, throttle response and the character of a highly boosted engine at that scale were all constraints a completely different architecture could address more directly than another evolution of the same block.

W16 era → V16 hybrid era. The Tourbillon is not simply a Chiron with more horsepower bolted on. It represents a different engineering philosophy: instead of forcing more air into an already maximized turbocharged engine, Bugatti went naturally aspirated for throttle response and character, then used electric motors to supply the low-end torque and all-wheel-drive traction that turbochargers used to provide. That is a deliberate architectural choice, not just a bigger number on a spec sheet.

Bugatti’s modern era began with the Veyron 16.4, which entered production in September 2005 at Molsheim, France, after a development program under the Volkswagen Group that had run for most of the preceding decade. Its 8.0-litre, quad-turbocharged W16 engine produced 1,001 PS (987 hp; 736 kW) and 1,250 Nm of torque, delivered through all-wheel drive. Months before deliveries began, a pre-production Veyron reached a verified 407.5 km/h (253 mph) at Volkswagen’s Ehra-Lessien test track in Germany — the first time a production-intent car had been documented above 400 km/h.

The Veyron’s real achievement was not the top-speed number by itself. Any number of experimental or track-only cars could claim extreme speed. Bugatti’s challenge was making a car that could approach 400 km/h-plus territory while still functioning as a road-going luxury automobile — with all-wheel-drive stability, a cabin trimmed to the standard of a grand tourer, and the thermal management to survive sustained high-speed running without melting itself. Ten radiators, a raft of cooling circuits, and an aerodynamics package that had to work at both city speeds and near 400 km/h were the less glamorous engineering problems the Veyron actually had to solve.

Over its decade-long production run, Bugatti progressively developed the Veyron platform rather than replacing it outright. The Veyron 16.4 Grand Sport (2009) introduced a removable targa roof without compromising structural rigidity. The Veyron Super Sport (2010, covered in detail below) pushed output to 1,200 PS and set a new production-car speed record. The Grand Sport Vitesse (2012) combined the open-top Grand Sport body with Super Sport-derived power, and a Vitesse-based World Record Edition later set a separate open-top speed record. Each derivative increased power, cooling capacity and aerodynamic refinement incrementally — a pattern of continuous evolution, rather than a wholesale redesign, that would define the Veyron’s entire production life.

Bugatti’s response to competitors closing in on the Veyron’s speed claims was the Veyron Super Sport, with output raised to 1,200 PS and a revised aerodynamic body. On June 26, 2010, at Ehra-Lessien, Bugatti test driver Pierre-Henri Raphanel piloted a Super Sport to an average 431.072 km/h (267.856 mph), calculated from two runs in opposite directions per Guinness World Records protocol. Guinness ratified it as the world’s fastest production car.

Context matters here. The record-setting car and the customer-specification Super Sport were not identical: production versions were electronically limited to 415 km/h (258 mph) specifically to protect the tyres at sustained high speed, a limitation Bugatti stated plainly rather than implying every customer car could replicate the record run.

Bugatti unveiled the Chiron at the Geneva Motor Show in March 2016 as the Veyron’s direct successor. It retained the 8.0-litre quad-turbo W16 layout but reworked it extensively — staged turbocharging that brought the second pair of turbos online progressively to reduce lag, larger intercoolers, and a new carbon-fibre monocoque. Output rose to 1,500 PS (1,479 hp; 1,103 kW) with 1,600 Nm of torque, and the car was electronically limited to 420 km/h (261 mph) in standard form. Production was capped at 500 units.

More power was only part of the story. The harder problem was making 1,500 PS controllable and repeatable — strong enough brakes to shed speed from beyond 400 km/h, a chassis and aerodynamics package that stayed stable across that entire range, and cooling capable of sustaining full power for longer than a single run. The Chiron’s real advance was in torque delivery, high-speed stability and everyday usability at a power level the Veyron never attempted.

Like the Veyron before it, the Chiron spawned a series of derivatives, each built to prove something specific rather than simply add trim.

Chiron Sport (2018)

What changed: Retuned suspension, a stiffer chassis and sharper steering, with the same 1,500 PS output. Why Bugatti built it: to answer criticism that the standard Chiron prioritized comfort over agility. What it proved: the platform had handling range beyond straight-line speed.

Chiron Pur Sport (2020)

What changed: Shorter gearing, a higher 9.0-second redline shift point, wider track and reduced weight, at the cost of a lower top speed. Why Bugatti built it: to create a track-focused Chiron for drivers who valued response over outright velocity. What it proved: the W16 architecture could be reconfigured for agility, not just top-end power.

Chiron Super Sport (2021)

What changed: A longer, lower “longtail” body derived from the 300+ program, refined aerodynamics and improved high-speed stability, replacing the standard Chiron in the lineup. Why Bugatti built it: to bring the engineering lessons from the 300+ record run into a broader production model. What it proved: the aerodynamic work behind the 300 mph run had road-car value beyond a single record attempt.

Chiron Super Sport 300+ (2021, customer cars)

Covered in full detail in the next section — the derivative built to commemorate the 2019 speed milestone, limited to 30 customer units.

On August 2, 2019, at Ehra-Lessien, Bugatti works driver Andy Wallace drove a modified Chiron Super Sport 300+ prototype — 250mm longer and lower than a standard Chiron, with reworked aerodynamics — to an uncharted 304.773 mph (490.484 km/h). It was the first time any road-legal-derived car had been documented past the 300 mph mark.

The distinction that matters: this was a single-direction test run, not a two-way average under Guinness protocol, and Bugatti has been explicit that it chose not to pursue official Guinness record status for it — consistent with the Volkswagen Group’s broader decision around that time to step back from the top-speed arms race among hypercar makers. Following the run, Bugatti built 30 customer Chiron Super Sport 300+ cars, each carrying a road-friendly, slightly higher ride height than the record prototype and an electronic limiter set to roughly 440 km/h (273 mph) — well below the prototype’s test speed. The last of the 30 was delivered in 2022, according to Bugatti’s own newsroom.

Through the early 2020s, Bugatti’s W16-era output narrowed toward increasingly specialized, lower-volume derivatives — the Chiron Super Sport, limited coachbuilt models like the Centodieci and Mistral, and the final Chiron Super Sport 300+ deliveries — rather than another jump in raw output. By the time the last W16-powered Chiron variants left Molsheim, the architecture had been in continuous production for nearly two decades.

After that long, the question stopped being how much more power Bugatti could extract from the W16. It became a question of what should replace it — and that answer arrived in June 2024.

Bugatti unveiled the Tourbillon on June 20, 2024, at its historic headquarters in Molsheim, France, as the Chiron’s successor and the first entirely new Bugatti model developed under the Bugatti Rimac ownership structure. It replaces the W16 with an 8.3-litre naturally aspirated V16, adds a three-motor hybrid system and a 24.8 kWh battery, sits on a new carbon-fibre monocoque, and carries a redesigned exterior and interior. Bugatti states a combined output of 1,800 PS (1,775 hp; 1,324 kW).

It is not, as some early coverage framed it, “an electric Bugatti.” The Tourbillon remains a combustion-engine hypercar at its core — the V16 alone still outproduces most flagship supercars — with hybrid assistance layered on for torque, traction and efficiency, not a switch to electric propulsion.

The Tourbillon’s engine displaces 8,355 cc (8.3 litres) across sixteen cylinders in a V configuration — a clean-sheet design, not a bored-out W16. Engineered in partnership with the British powertrain specialist Cosworth, it is naturally aspirated: no turbochargers, no forced induction of any kind. On its own, before any electric assistance, the engine produces 1,000 PS (986 hp; 735 kW) at 9,000 rpm, with a redline around 9,500 rpm — a rev range no previous Bugatti W16 came close to and one only possible because there are no turbochargers’ spool characteristics to work around.

Veyron/Chiron: 8.0-litre quad-turbo W16.
Tourbillon: 8.3-litre naturally aspirated V16 plus a three-motor hybrid system.

The comparison is conceptual, not a simple “better than” statement — both architectures were built to solve different problems for their era. The W16’s turbocharging delivered massive low-end torque for a straightforward, if extreme, power figure. The V16’s naturally aspirated design trades some of that low-end torque for throttle response and revving character, then relies on electric motors to fill the gap turbochargers used to cover.

Three electric motors do work the W16’s turbochargers used to do, plus more. Two motors sit on the front axle, giving the Tourbillon all-wheel drive without a mechanical driveshaft running the length of the car, and supplying instant torque at low RPM where a naturally aspirated V16 is comparatively weaker. A third motor is integrated into the rear-mounted eight-speed dual-clutch transmission, adding traction and torque-fill at the rear axle. Together they contribute roughly 800 PS (789 hp; 588 kW) to the combined total.

The 24.8 kWh battery also gives the Tourbillon something no Veyron or Chiron ever had: a genuine electric-only mode, with Bugatti citing roughly 60 km (about 37 miles) of EV-only range — useful for low-speed city driving and a meaningful step toward the efficiency requirements shaping every corner of the car industry, not just Bugatti’s segment of it.

It’s a common shorthand to say “the Tourbillon has an 1,800 PS engine,” and it’s inaccurate. The engine alone produces 1,000 PS; the remaining roughly 800 PS comes from the three electric motors, combined with the engine’s output under Bugatti’s stated system total of 1,800 PS (1,775 hp; 1,324 kW). Attributing the full figure to the V16 misstates where the performance actually comes from — a bit more than half from combustion, the rest from electrification.

Bugatti has stated performance figures of roughly 2.0 seconds to 100 km/h, and a top speed target of 445 km/h (276 mph), electronically limited. As of the car’s unveiling, that top-speed figure was a stated engineering target rather than an independently verified, ratified production-car speed record in the way the Veyron Super Sport’s 431.072 km/h run was.

Almost every modern hypercar rival uses forced induction somewhere in its powertrain, which makes the Tourbillon’s naturally aspirated V16 a deliberate outlier, not a step backward. Bugatti’s stated reasoning centers on throttle response — a naturally aspirated engine reacts to the accelerator without the lag inherent to spooling a turbocharger — and on character: a 9,000 rpm-plus V16 has a sound and revving sensation no turbocharged engine, however powerful, replicates. It’s also a matter of driver engagement and Bugatti’s own engineering identity, distinguishing the Tourbillon from the sea of turbocharged and fully electric hypercars around it.

This is a subjective, character-driven decision, not an objective performance argument — naturally aspirated engines are not inherently superior to turbocharged ones for outright output, and Bugatti’s own hybrid system exists precisely to supply the low-end torque a turbo would otherwise provide. It should be read as Bugatti choosing a specific emotional and engineering identity for its next two decades, the same way the W16 defined the previous two.

The V16 was engineered in partnership with Cosworth, the British powertrain specialist best known for Formula 1 and motorsport engine work, rather than by Bugatti alone or by Cosworth alone. Bugatti’s own engineers in Molsheim led the concept and integration into the car; Cosworth’s Powertrain division in the UK handled significant detailed engineering and manufacturing execution, including solving the packaging and vibration challenges of an exceptionally long crankshaft and camshaft assembly at that cylinder count. Describing Cosworth as having “developed the entire Tourbillon” overstates the relationship; describing it as a manufacturing subcontractor with no design input understates it. The accurate framing is a genuine joint engineering effort on the engine specifically, not the whole vehicle.

The Tourbillon’s exterior keeps Bugatti’s signature horseshoe grille and central spine but wraps them around a more sculpted, aerodynamically driven body than the Chiron’s, with active aero elements and a rear treatment shaped around cooling and downforce needs rather than styling alone. Inside, Bugatti deliberately pulled back from the large-touchscreen approach common across the rest of the hypercar and luxury-car industry, emphasizing exposed mechanical craftsmanship — titanium structural elements, machined switchgear and an instrument cluster built like fine watchmaking — over a cabin dominated by a central display.

The Tourbillon’s instrument cluster is built from titanium components with sapphire-crystal elements, styled and engineered like a mechanical wristwatch — the source of the car’s name, itself a reference to a watchmaking mechanism prized for precision. Physical, machined controls replace many of the touch-sensitive surfaces found elsewhere in the segment. A secondary display for infotainment functions is designed to remain hidden by default and rotate into view only when needed, rather than dominating the dashboard as a permanently visible screen. Bugatti has not stated the cabin is entirely screen-free, and this page does not make that claim — the emphasis is on minimizing, not eliminating, digital displays.

Bugatti will hand-build 250 Tourbillon units at a newly constructed Atelier adjacent to its Molsheim headquarters, at a pace of roughly 80 cars per year once full production ramps up. This figure refers to total planned production, not an initial batch or a special edition within a larger run. Multiple reports since the reveal indicate the full 250-unit allocation was reserved by customers well before deliveries began.

Bugatti’s announced starting price is €3.8 million, net of taxes. That figure excludes the taxes, import duties, options and the extensive bespoke customization Bugatti buyers typically add, which routinely push a final car’s price well above the base figure. In dollar terms, reporting at the time of the reveal put this at roughly $4 million, though that conversion moves with the euro-dollar exchange rate on any given day and should not be read as a fixed number.

Following the June 2024 unveiling, Bugatti moved through structural validation, powertrain testing and prototype development, with test cars appearing on public roads through 2025 and into 2026 as part of that program. Production readiness at the new Molsheim Atelier and the start of customer deliveries have been targeted for late 2026 across Bugatti’s own communications and independent reporting through the year. As of this page’s publication, that remains the current, publicly stated delivery target — not yet a completed milestone, and this page will be updated if Bugatti confirms deliveries have begun.

Not in any way that can currently be verified. “Fastest” gets used loosely across several distinct claims that shouldn’t be mixed together: acceleration (0-100 km/h or 0-60 mph time), claimed top speed (a manufacturer’s stated figure or electronic limiter), a verified production-car speed record (an independently ratified, two-direction run, like the Veyron Super Sport’s), a prototype speed (like the Chiron Super Sport 300+’s 2019 run, not ratified as a two-way record), and a limited-production or one-off car’s speed, which is a different category from a car built in the hundreds. The Tourbillon’s 445 km/h figure is a stated target and electronic limit; it has not, as of publication, been run and independently ratified as a production-car speed record. Until that happens, “fastest car in the world” is not an accurate description of the Tourbillon, however credible Bugatti’s engineering track record makes the claim sound.

The Veyron made the impossible seem production-ready. The Chiron refined that formula, taking the same basic architecture to 1,500 PS while making it more controllable. The Tourbillon changes it. Bugatti’s move from a quad-turbo W16 to a naturally aspirated V16 hybrid is more consequential than another horsepower increase — it marks the end of one of the most recognizable engine eras in modern automotive history, and the start of a new approach to what a hypercar should be.

The Veyron asked how fast a road car could go. The Chiron asked how far the formula could be pushed. The Tourbillon asks what a hypercar should become next.
