Compare the2024 Porsche 911VS 2024 Bugatti Chiron

The 911 (except GT3) has standard Warn and Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Chiron doesn't offer collision warning or crash mitigation brakes.

A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Chiron doesn’t offer a night vision system.

The 911’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Chiron doesn’t offer a lane departure warning system.

To help make backing out of a parking space safer, the 911’s optional Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The Chiron doesn’t offer a rear cross-path warning system.

The 911 has standard Porsche Connect, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Chiron doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the 911 and the Chiron have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems and around view monitors.

There are almost 18 times as many Porsche dealers as there are Bugatti dealers, which makes it much easier should you ever need service under the 911’s warranty.

J.D. Power and Associates rated the 911 second among premium sporty cars in their 2023 Initial Quality Study. The Chiron isn’t in the top three in its category.

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The Chiron doesn’t offer a boxer engine configuration.

On the EPA test cycle the 911 Coupe gets better mileage than the Chiron:

In heavy traffic or at stoplights the 911’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Chiron doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Porsche 911 higher (3 to 5 out of 10) than the Bugatti Chiron (1). This means the 911 produces up to 39 pounds less smog-producing pollutants than the Chiron every 15,000 miles.

An eight-speed automatic (SMG) is standard on the Porsche 911, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Chiron.

The 911 stops much shorter than the Chiron:

The 911 (except Base/GT3) offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Chiron doesn’t offer an active sway bar system.

The 911 GT3 handles at 1.17 G’s, while the Chiron Sport pulls only 1.06 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 911 GT3’s turning circle is 15.7 feet tighter than the Chiron’s (34.1 feet vs. 49.8 feet). The 911’s turning circle is 13 feet tighter than the Chiron’s (36.8 feet vs. 49.8 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs about 600 to 1000 pounds less than the Bugatti Chiron.

The 911 is 6.6 inches narrower on average than the Chiron, making the 911 easier to handle and maneuver in traffic.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Chiron doesn’t offer active grille shutters.

The 911 has standard seating for 4 passengers; the Chiron can only carry 2.

The 911 has 19 cubic feet more passenger volume than the Chiron (73 vs. 54).

The 911 Coupe has a much larger trunk with its rear seat up than the Chiron (4.6 vs. 2 cubic feet).

The 911’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Chiron’s

While driving with high beams on, sensitive light sensors available for the 911 detect other vehicles which could be blinded and automatically switch to low beams. The Chiron doesn’t offer automatic dimming high beams.

Optional air-conditioned seats in the 911 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Chiron doesn’t offer air-conditioned seats.

On extremely cold winter days, the 911’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Chiron doesn’t offer a heated steering wheel.

The 911’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Chiron doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the 911 (except Manual) offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Chiron doesn’t offer an adaptive cruise control.

The 911’s standard separate stalk mounted cruise control is close at hand. The Chiron’s standard cruise control is on an over-crowded turn signal stalk.

Standard Connect Plus for the 911 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, finding fuel prices at nearby service stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The Chiron doesn’t offer factory integrated smartphone program access.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Garage Pilot will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Chiron doesn’t offer an automated parking system.

The Porsche 911 comes in coupe and convertible bodystyles; the Bugatti Chiron isn’t available as a convertible.

The 911 is available in both rear-wheel drive and all-wheel drive configurations. The Chiron doesn’t offer a two-wheel drive configuration.

J.D. Power and Associates rated the 911 first among premium sporty cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Chiron isn’t in the top three.
