7 4-Cylinder Cars With More Horsepower Than A Ford Mustang EcoBoost

Key Points:

• The 2026 Ford Mustang EcoBoost features a 2.3-liter turbocharged four-cylinder engine producing 315 horsepower, matching the power of the 2010 V8 Mustang GT and surpassing many earlier V8 models from the '90s and 2000s.
• Several four-cylinder vehicles outperform or match the Mustang EcoBoost in horsepower, including the Acura Integra Type S (320 hp), Cadillac CT4-V (325 hp), Volkswagen Golf R and Audi S3 (both 328 hp), and Porsche 718 Cayman S/Boxster S (350 hp).
• The Acura Integra Type S and Honda Civic Type R share a 2.0-liter turbo engine, with the Integra producing slightly more power, while GM's 2.7-liter turbocharged four-cylinder engine in the Cadillac CT4-V offers more horsepower but will lose prominence as the CT4 is discontinued after 2026.
• The Volkswagen Golf R and Audi S3 provide advanced all-wheel-drive systems and high horsepower (328 hp), making them among the quickest four-cylinder performance vehicles on the market, with the Golf R updated for 2025 to enhance power.
• The 2026 Toyota RAV4 Plug-In Hybrid uniquely delivers 324 combined horsepower through a naturally aspirated 2.5-liter four-cylinder engine paired with electric motors, demonstrating hybrid technology's potential to boost performance and fuel efficiency beyond traditional turbocharged engines.
