Filed under: Coupe , Performance , Scion , Subaru , Toyota , Rumormill Teaser images of a purported Subaru BRZ STI were uncovered last night and sent the internet into a collective state of hysterics. That’s not hugely surprising, though, considering the reverence that the BRZ, along with its fraternal twins, the Scion FR-S and Toyota GT86, have garnered from the automotive media. The sole sticking point, really, has been its mere 200 horsepower. People have been chomping at the bit over a higher output version of the sublime rear driver. Those same people may be in for a disappointment, though. See, the BRZ STI that was teased last night might not be a real STI. Instead, it’s looking like it might be a BRZ tS. According to 7Tune.com , the timing of the photos posted on Subaru’s website lined up with Subaru’s 86 Festival at Fuji Speedway , where the Subaru BRZ tS debuted. Despite wearing STI badges, the tS isn’t the full-tilt STI model we’ve been hoping for. Instead, you can think of the relationship between tS models and STI models as sort of like the difference between a BMW 3 Series M Sport and a BMW M3.
