These legendary four-cylinder engines proved that outstanding performance never depended on having six or eight cylinders.
Four-cylinder engines are often seen as practical powerplants built for everyday transportation. Many people assume that true performance cars must rely on large, multi-cylinder engines. History, however, tells a different story. Over the past three decades, several four-cylinder engines have earned legendary status thanks to their performance, durability, and tuning potential.
Few four-cylinder engines have built a reputation quite like Mitsubishi's 4G63. The original G63 debuted in 1980 as a fuel-injected 2.0-liter engine producing around 170 horsepower. While it delivered solid performance, its single-overhead-cam cylinder head limited its potential.
That changed in 1987, when Mitsubishi introduced a dual-overhead-cam, 16-valve cylinder head along with turbocharging. The result was the now-famous 4G63T.
The turbocharged engine first appeared in the Mitsubishi Galant VR-4, where it helped turn the all-wheel-drive sedan into a serious rally contender. It later became the heart of numerous Mitsubishi performance models, most notably the legendary Lancer Evolution.
The 4G63 quickly became a favorite among enthusiasts. With relatively modest upgrades, 500 horsepower was well within reach, while heavily modified builds have exceeded 1,000 horsepower. Just as important, the engine earned a reputation for exceptional reliability and straightforward serviceability.
Another Japanese icon on this list is Honda's F20C, the naturally aspirated engine that powered the Honda S2000 from 1999 through 2009.
Displacing just 2.0 liters, the F20C produced an impressive 250 horsepower in Japanese-market specification, delivering an astonishing 125 horsepower per liter without forced induction. At the time, it set a benchmark for naturally aspirated production engines, a record that stood until Ferrari surpassed it roughly a decade later.
Its remarkable output wasn't the only reason enthusiasts admired it. Thanks to Honda's VTEC variable valve timing system and lightweight internal components, the engine loved high rpm, with a factory redline of 8,900 rpm.
The F20C became a favorite in both motorsports and the tuning community, and it was named International Engine of the Year in its class for five consecutive years.
Toyota's 3S engine family ranks among the company's most successful, but the naturally aspirated 3S-GE and its turbocharged sibling, the 3S-GTE, stand out as the stars of the lineup.
Developed with assistance from Yamaha, the 3S-GE first appeared in the 1984 Toyota Vista. Its design successfully balanced strong performance with outstanding reliability. Over the years, Toyota continuously refined the engine, increasing output from approximately 160 horsepower to as much as 210 horsepower.
The fifth and final evolution arrived in 1998 under the hood of the Japanese-market Toyota Altezza RS200. Nicknamed the "Black Top" because of its black valve cover, it featured a higher compression ratio, dual VVT-i variable valve timing, electronic throttle control, and titanium valves on manual-transmission models. In this configuration, the engine produced 210 horsepower at 7,600 rpm.
For many enthusiasts, the 3S-GE represents Toyota's last truly old-school high-performance four-cylinder—powerful, durable, and built to last.
Japan wasn't the only country producing exceptional four-cylinder engines. In 1990, Saab introduced the outstanding B234 for the Saab 9000.
The 2.3-liter, 16-valve engine produced between 150 and 170 horsepower in naturally aspirated form, while turbocharged versions delivered anywhere from 194 to 225 horsepower, depending on model year. More importantly, it earned a reputation for remarkable durability.
Comparing the later B235 to the earlier B234 reveals just how robust the original design was. The B234 featured a massive cast-iron engine block along with stronger pistons and connecting rods, making it far more desirable for high-horsepower builds. It's no surprise that enthusiasts routinely push these engines to around 500 horsepower, while the newer B235 rarely receives the same attention.
At one point, internet rumors claimed Russia's ZMZ-406 engine was copied from the Saab B234, but there's no evidence to support that theory.
Including Volkswagen's EA888 on a list like this may spark debate. Early versions earned criticism for several well-known reliability issues, and some of that criticism was justified. Still, the complete story is far more nuanced.
Introduced in 2006, the EA888 was installed in a wide variety of Volkswagen Group vehicles. Built around a cast-iron block with a 16-valve cylinder head, it was offered in both 1.8-liter and 2.0-liter configurations. First-generation engines produced between 120 and 200 horsepower but suffered from excessive oil consumption, timing chain problems, and oil pump failures.
Volkswagen addressed most of those issues with the second generation, significantly improving long-term reliability.
The EA888 also became one of the most tuner-friendly turbocharged four-cylinders on the market. A simple ECU calibration could raise a 180-horsepower 1.8-liter engine to roughly 200 to 230 horsepower. With upgraded hardware, output of 350 horsepower or more became entirely achievable.
Despite the criticism that has followed parts of its history, the EA888 remains one of the defining modern four-cylinder engines and deserves to be mentioned alongside the other legendary powerplants on this list.
