How Many Cylinders Can a Car Have at Most?

Currently, the engine with the most cylinders used in cars is an 18-cylinder engine, found in the Bugatti concept sports car. Common cylinder counts for car engines include 3, 4, 5, 6, 8, 10, and 12 cylinders. Engines with displacements of 1 liter to 1.5 liters typically use 3 cylinders, 2.0-liter engines are generally 4-cylinder, 2.5-liter engines are usually 5-cylinder, and engines around 3 liters are typically 6-cylinder. Early models like the Xiali, Alto, Chery QQ, and BYD F0 all used 3-cylinder engines. To save on manufacturing costs, automakers have once again adopted 3-cylinder engines, as seen in models like the BMW 1 Series, Honda Lingpai, Geely Binyue, and Buick Excelle. The most commonly used engine in cars is the 4-cylinder engine. The reason is that the inline-four configuration currently offers the highest stability and NVH (Noise, Vibration, and Harshness) levels closest to those of multi-cylinder, large-displacement engines. Its symmetrical structure, synchronized operation, 180-degree firing interval, and the application of balance shaft technology achieve a sufficiently high level of performance. Inline-five-cylinder engines also exist. Audi once used this type of engine extensively, and currently, the Ford Ranger (a pickup truck) still employs a 5-cylinder diesel engine. These engines offer smoother performance than 4-cylinder engines, with a firing interval of just 144 degrees. Large-displacement engines often use 6/8/12-cylinder "V-type" or "W-type" internal combustion engines. These engines are primarily found in ultra-high-performance sports cars from brands like McLaren, Ferrari, Lamborghini, Aston Martin, Rolls-Royce, and Maybach.
As a car enthusiast, I once saw a Bugatti Veyron at an auto show. It has 16 cylinders, and the exhaust roar is as loud as thunder, with acceleration so fast it feels like flying. Why so many cylinders? Just to unleash 1600 horsepower and give you an exhilarating experience on the track. But the downsides are obvious: fuel consumption is extremely high, requiring refueling after just a few hundred kilometers per tank, making city driving a pure waste of money. Ordinary cars like my Civic with 4 cylinders are sufficient, and even 6-cylinder SUVs like the Highlander handle hills without issue. More cylinders mean a smoother and quieter engine, especially in luxury cars with 12 or more cylinders, which drive as smoothly as silk. However, maintenance costs are sky-high—replacing a single part could cost as much as a new car. The current trend is reducing cylinders while adding turbochargers or electric motors to improve efficiency, and electrification may eventually make such engines history. In short, 16 cylinders represent the extreme, suitable only for wealthy enthusiasts, while ordinary folks are better off opting for smaller-displacement engines.
Thinking back to the old Ford Mustang V8 I drove in my youth, those 8 cylinders felt incredibly powerful. Nowadays, cars can have up to 16 cylinders, reserved for hypercars like Bugatti. Why such a big change? The muscle car craze of the 1960s and 70s pushed cylinder counts higher, but as technology advanced, manufacturers found turbocharging could compensate for smaller engines. Coupled with tightening environmental regulations, high-cylinder cars gradually became rarer. Models with up to 16 cylinders are extremely few, exorbitantly priced, and a hassle to maintain. In contrast, modern SUVs like the Cayenne perform perfectly well with just 6 cylinders for daily commuting. While more cylinders mean better acceleration and lower noise, their emissions fall far short of green standards. It's recommended to opt for 4-6 cylinder cars or hybrid versions—saving money while reducing carbon footprint.
From a technical perspective, the maximum number of cylinders in a car is typically 16, such as the W16 layout in Bugatti. This design aims to enhance power and smoothness: more cylinders distribute ignition vibrations, resulting in smaller shocks and more linear acceleration. However, each additional cylinder increases weight and friction, leading to a significant rise in fuel consumption, along with greater cooling challenges and higher maintenance costs. Regular cars with 4-6 cylinders strike a balance between performance and economy, while engines with 8 or more cylinders cater primarily to performance enthusiasts. With modern turbocharging and electric assistance, smaller engines can now deliver substantial power, reducing the importance of cylinder count. Don’t blindly chase more cylinders—choosing what suits your needs is key.
