Sedans Performance
From daily commuters to super saloons. Analyze the performance of 4-door vehicles.
The Sleeper Factor
Sedans often hide serious performance under a practical exterior. Modern "Super Saloons" can rival dedicated sports cars in a straight line, thanks to massive engines and advanced all-wheel-drive systems.
However, the extra weight of rear doors, soundproofing, and luxury features means they need significantly more horsepower to achieve the same Power-to-Weight ratio as a coupe.
Sedan Tiers
- Economy (e.g., Civic) ~90 hp/ton
- Sport Sedan (e.g., 3 Series) ~180 hp/ton
- Super Saloon (e.g., M5, E63) ~300+ hp/ton
Practicality vs Physics
The challenge for sedans is maintaining comfort without sacrificing agility.
Aero
Longer wheelbases often provide better high-speed stability.
Weight
Average sedan is 200-300kg heavier than a comparable coupe.
AWD
Common in fast sedans to manage high torque figures.
