Subaru, together with its Subaru Tecnica International (STI) tuning arm, will be displaying two production-derived concept cars at the upcoming Tokyo Auto Salon this January.
The first will be the Subaru BRZ STI Concept. Though the Japanese carmaker didn't say if this is the same vehicle as the Subaru BRZ Concept-STI it unveiled at the LA Auto Show November, it did reveal that the car received some STI tuning and original parts, which include carbon-fiber bonnet and roof, to not only reduce its weight but to also enhance its stable straight-driving and cornering performance.
Other add-ons to the BRZ STI Concept are the under spoiler, boot spoiler, sport muffler, flexible tower bar, low down spring, 18-inch aluminum wheels, Brembo brakes and rotors and Bilstein dampers.
The second concept car Subaru will put on display is the Impreza G4 STI Concept. Based on the production Japanese market-model G4 2.0i-S, which was launched only in November, Subaru claims it has the same acceleration performance as the previous 2.5-liter models.
According to Subaru, by adopting special tuning in pursuit of STI's "strength and nimbleness driving" vehicle development theme, the G4 STI Concept "offers excellent controllability and maneuverability to any driver who loves driving pleasure."
The STI-developed equipment the G4 STI Concept received are the front and side under spoilers, a boot spoiler, a skirt lip, sport muffler, flexible tower bar, low down spring, stainless steel mesh brake hose and 18-inch aluminum wheels.
