The differences between the Focus RS and ST are: 1. Different engines: The Focus RS is equipped with a 2.3-liter turbocharged direct-injection engine; the Focus ST is equipped with a 2.0-liter four-cylinder gasoline engine. 2. Different top speeds: The Focus RS has a top speed of 266 km/h; the Focus ST has a top speed of 248 km/h. Both models are classified as compact cars, both use a 6-speed manual transmission, and both feature MacPherson strut independent front suspension and multi-link independent rear suspension. The body dimensions are basically the same, with the Focus RS being 28mm longer than the Focus ST.

I've personally driven the Focus ST and RS several times, and the difference is huge. The ST is easy and comfortable to drive, with around 280 horsepower, front-wheel drive that's agile in corners, and better daily comfort with a suspension that's not too bumpy. But the RS is a beast, with all-wheel drive and over 350 horsepower, delivering an intense push-back feeling at launch. Its drift mode makes it excel on the track, though the hardcore suspension can make it bounce on city roads. The RS leans more towards extreme driving, while the ST is the top choice for daily fun. If you love racing or hitting the track, the RS is absolutely thrilling, but for daily commuting, the ST is more worry-free, fuel-efficient, and less demanding.

The engines and drivetrains of the Focus RS and ST are the key differentiators. The ST uses a 2.0 or 2.3-liter turbocharged engine with around 280 horsepower, primarily front-wheel drive, balancing sportiness and practicality, with fuel consumption ranging from 9-10L/100km. The RS upgrades to a high-boost 2.3-liter version, exceeding 350 horsepower, paired with an all-wheel-drive system for more direct power delivery and even a drift mode. The RS also features stiffer suspension and superior braking performance. On the road, the RS feels like a rocket hugging the track, while the ST is more like a lively performer on regular streets. Maintenance costs differ as well, with the RS potentially requiring more upkeep investment.

If you're considering budget, the ST is much more affordable than the RS. The price difference for new cars is tens of thousands, and in the used car market, the RS is twice as expensive with significantly higher insurance costs. The RS has explosive power but fuel consumption exceeds 12L/100km, while the ST is more fuel-efficient and comfortable for daily driving. I recommend test driving first: the ST is easy to handle on city roads with softer seats that don't strain your back; the RS is cool but has a strong bumpy feel, which family members might complain about. From an economic perspective, the ST is a wise choice, leaving the RS for true enthusiasts. In the long run, the RS may hold its value better, but daily expenses are higher.
