What is the fastest Subaru STI car?
The history of Subaru’s STI brand is long, but few road-ready cars have been built. The current range of production cars includes only one STI model. The United States has known only three other cars developed by Subaru Tecnica International.
Each brought their own talents, looks, and personalities. But, when horsepower is the name of the game for STI sports cars, it begs the question: which STI is faster? The Subaru S209, the WRX STI, the Series.White or the BRZ tS?
The 2020 Subaru S209 goes from 0 to 60 in 4.7 seconds
This sports car was the first Subaru STI S model to land on American shores. Critics and fans alike applauded the S209 as the most powerful car the brand had ever created. It was built on the bones of the classic Subaru WRX STI.
By far, the S209 is the fastest Subaru STI car in the lineup. The S209 offered an upgraded SUBARU BOXER engine with a larger turbocharger, which delivered 341 horsepower and an incredible sprint time of less than five seconds from zero to sixty.
The 2021 Subaru WRX STI goes from 0 to 60 in 5.3 seconds
The proven STI is the fastest production Subaru WRX you can buy. Car & Driver released the results of its testing of the 2021 model, and the WRX STI sprinted from zero to sixty mph in just over five seconds.
The WRX STI comes standard with a 305 horsepower engine mated to a six-speed manual transmission. This model is also the only Subaru STI sports car available for purchase – all other models have been retired. The WRX model could also be the last STI car to run on an internal combustion engine. This can mark the end of a legacy.

The 2020 Subaru WRX STI series. White goes from 0 to 60 in 6 seconds
This fleeting beauty was not as spectacular as critics had hoped. MotorTrend reported on this model a few years ago, noting some disappointments. The STI Series.White offered the same 2.5-liter turbo engine as the regular WRX STI. Specs remained the same at 310 hp and 290 lb-ft of torque. The main differences between the WRX STI and the STI Series.White were mostly cosmetic. The paint, wheels and seat upholstery were the main differentiators.
A big surprise? The most powerful 310 horsepower STI series. White was actually slower in testing than the 268-hp WRX STI. The Series.White went from zero to sixty in six seconds. Its less powerful sibling did it in 5.6 seconds.

The 2020 Subaru BRZ tS goes from 0 to 60 in just over 6 seconds
The Subaru BRZ tS, which stands for “tuned by STI,” was a brief bright spot in the STI lineup. It came standard with a sports suspension developed by STI and a stiffer chassis than the conventional BRZ model. Its 4.0-cylinder engine was good for 205 horsepower and 156 lb-ft of torque, and it offered a spicy ride.
Finding precise numbers for the 2020 BRZ tS can get tricky, with little clear agreement among reviewers. However, Car & Driver reported that the 2018 Subaru BRZ tS went from zero to sixty in about 6.3 seconds. Since there were no significant powertrain changes in the 2018 BRZ tS compared to 2020, we can assume that the 0-60 times were about the same.
