Audi S3 and RS3 differences: 1. Different engines: The S3 is powered by a 2.0L inline 4-cylinder turbocharged engine; the RS3 is powered by a 2.5L inline 5-cylinder turbocharged engine. 2. Different horsepower: The S3's 2.0L turbocharged engine delivers a maximum power and torque of 210KW and 380NM; the RS3's 2.5L turbocharged engine delivers a maximum power and torque of 270KW and 465NM. The Audi S3 is a model under the Audi brand, with body dimensions of 4474mm in length, 1796mm in width, 1392mm in height, and a wheelbase of 2628mm; paired with a bold continuous waistline, the body proportions appear very refined and dynamic.

As someone who frequently researches performance cars, I'm very familiar with the differences between the Audi S3 and RS3. The S3 is equipped with a 2.0T four-cylinder engine producing around 300 horsepower, which is more than sufficient for daily driving. In contrast, the RS3 features a unique 2.5T five-cylinder powerplant starting at 400 horsepower, delivering a completely different level of acceleration thrust. The chassis tuning also differs significantly between the two - the S3 leans more towards comfort with less harshness over speed bumps, while the RS3 has stiffer, more direct suspension that provides noticeably better road-holding on mountain passes. Externally, the RS3 boasts exclusive designs for its grille, wheels, and mirror housings, along with upgraded six-piston brake calipers. Price-wise, the RS3 costs over 100,000 RMB more than the S3, but actually holds its value better in the used car market thanks to the distinctive five-cylinder engine note and its relative rarity.

I was torn between these two models when choosing a car, and found that the S3 and RS3 have different positioning. The S3 is the cost-effective choice, priced at just over 400,000 yuan, with a daily commute fuel consumption of around 8-9 liters, and sufficient rear space for picking up kids. The RS3 leans more towards the enthusiast crowd, priced at over 500,000 yuan, with fuel consumption often exceeding 12 liters. The rear space remains the same, but the chassis is noticeably stiffer. Performance-wise, the RS3's five-cylinder engine has greater tuning potential, easily surpassing 500 horsepower with a simple ECU tune, while the S3's four-cylinder engine tops out at around 400 horsepower. In terms of details, the RS3 features carbon fiber trim and Alcantara seats, but the infotainment system is identical. Maintenance costs are worth noting, as replacing brake discs on the RS3 costs twice as much as on the S3.

The core difference between these two cars lies under the hood. The S3's 2.0T four-cylinder engine handles city driving with ease, paired with a smooth-shifting 7-speed dual-clutch transmission. The RS3's unique 2.5T five-cylinder engine is Audi's signature masterpiece - its distinctive "boiling water" startup sound alone wins hearts. The 100-horsepower gap translates to a 1-second difference in 0-100km/h acceleration (4.8s for S3 vs 3.8s for RS3). On track, the RS3 shows superior stability with its quattro system featuring torque vectoring. However, the S3 offers lighter steering for daily driving and more fuel-efficient performance. Don't just compare specs - take test drives to experience their engine notes firsthand to truly understand the difference.
