Subaru BRZ STI tS Teased

Subaru's STI tuning arm has released teaser images of a new enhanced BRZ model on its Japanese website today, kicking the rumour-mill into overdrive. 

Exactly what the images promise is unclear, although there has been no shortage of reports over the past year pointing to a top-shelf turbocharged version of the BRZ. 

The website has revealed little, showing only a pair of images cropped tightly on the familiar STI logo, followed by the slogan 'Purity of Handling'. 

The company has inadvertently given away one key detail, however: the file names for the teaser images are appended with the letters 'tS' - which stands for 'tuned by STI'.
