What Is the Main Difference Between WRX and STI?

The main difference between WRX and STI is in their power and performance, as the STI model has a stronger engine, more powerful brakes, stiffer springs and thicker tires than the WRX. While both are high-performance cars, the Subaru STI has more power than the Subaru WRX.

On the Subaru WRX STI, you get 305 horsepower and 290 pound-feet of torque, which is way more than the 271 horsepower and 258 pound-feet of torque offered by the WRX model. It should not be confused with the Subaru Impreza WRX.
Aside from that, they have other differences in their styling, trim levels, brakes, and suspensions. Here are the various ways both car models differ.

– Engine Power and Performance

The most obvious comparative difference between the two models is their engine power. The Subaru WRX STI is powered by the EJ25 engine, which is a 2.5-liter turbocharged flat-four engine with 305 horsepower. As for the WRX, it uses a newer motor called the FA20. This is a 2.4-liter turbocharged flat-four engine with 271 horsepower.

Their driving performances are also different, as you can accelerate from 0 to 60 in 4.8 seconds when using the STI, but it takes 5.4 seconds with the WRX model. If you’re choosing your car based on speed, you should consider this.

– Transmission

Even if both cars come with a six-speed manual transmission, they are not exactly the same. The WRX also has a simulated 7-speed continuous variable transmission gearbox, which is powerful. On the WRX STI, you get a TY85 transmission, which is a fully synchronized close-ratio system for more power.

– Suspension

In terms of the suspension, the Subaru models have different setups and ride heights. While both cars are designed with independent suspension in all corners, the STI has a high-performance tuned suspension, while the WRX features a sport-tuned suspension.

The WRX suspension is designed to take some abuse for off-road driving, but it would also run smoothly on a city road. As for the STI suspension, it takes even more punishment, but this makes it a bit uncomfortable and stiff for riding in the city.

– Brakes

Another difference between both models is their brakes. Both cars are designed with brake discs all around, but while the WRX features standard solid disc brakes, the STI has something more powerful. The Subaru STI is equipped with Brembo brakes, which are designed with 2 piston calipers in the back, six in the front, and ventilated discs.

– Trim Levels

Both car models have different trim levels that you should keep in mind. With the WRX, you can choose between WRX Base, WRX Premium and WRX Limited, which cost between $29,000 and $33,000. As for the WRX STI, it comes with two trim levels, as STI Limited is divided into two. The other level is Base. The cars cost between $38,000 and $43,000.

While the STI has limited options in terms of its trims, they are more expensive. You can consider the price if you are working with a tight budget. The cars are also different in the types of upgrades that you can get. From the base WRX, you can upgrade to an exhaust system and shift mode from the STI model. You can also upgrade some parts of the WRX Premium.

Another aspect to consider when looking at the trims is the standard equipment they come with. The base models of both cars are designed with different features, but the STI offers more. It comes with a 7.0-inch multimedia system, which is an upgrade of the 6.5-inch screen on the WRX model. Keep in mind that the 2023 WRX has a 7.0-inch screen.

The STI Base also comes with heated front seats, keyless access, a dual-zone climate control system, a steering responsive headlights system, automatic headlights, and leather-trimmed upholstery. As for the WRX Base, they come with some features like keyless entry, electronic cruise control, and a rear vision camera.

– Style

Both cars look the same when you consider their style, and most car owners can only differentiate them based on the fact that the STI has a wing at the back of the exterior. But you can also notice that the STI has a rear diffuser, bigger breaks and wheels, and badges on the grill and back. The WRX does not have these features.

You might also notice some differences in their interior design. The interior features a DCCD selector behind the stick of the STI, as it has a regular handbrake. This is unlike the electronic handbrake on the WRX. You will also notice STI badges on the wheel, gauges and dash. It features a red shift knob too.

One way to differentiate the cars is if you see an automatic transmission. This is only found on WRX models, as WRX STI only comes with a manual. This makes it a fantastic choice for drivers who prefer manual driving.

– Speed

The STI is faster than the WRX by about 0.6 seconds. While the STI can reach 0-60 in 4.8 seconds with a top speed of around 155 mph, the WRX will reach the same in 5.4 seconds while the top speed is 145 mph.

You should buy an STI over a WRX if you are looking for more speed and performance, especially on the track. The STI comes with a stronger engine and brake system, bold styling and design, smooth handling on the manual transmission, and higher horsepower and torque.
