Tetsuya Tada, Toyota’s chief engineer on the Scion FR-S, has said that the FR-S and the Subaru BRZ will definitely get an engine performance upgrade when the cars are refreshed in 2015.
“We [have] already tried all possibilities and there are several types of 86 prototypes at the Toyota proving ground now; one is a turbocharger, one is bigger displacement and [the other is a] special hybrid system,” Tada told the Sydney Morning Herald. “All possibilities are being considered.”
Tada wouldn’t go on record about which performance upgrade the FR-S and BRZ will get, but the SMH claims inside sources are telling them the Scibaru twins will get a bigger 2.5-liter engine. The Scion FR-S and Subaru BRZ 2.5 engine will supposedly have 255-horsepower, a 25% bump over the stock 200-hp to go with the 25% displacement bump and almost as much horsepower as the Subaru WRX.
Using a 2.5-liter engine in the FR-S and BRZ is preferable to a turbocharger because it is believed the forced induction route would result in too much extra stress on the drivetrain, according to the inside sources. The hybrid idea was scrapped because of the added weight and complexity that would take the cars away from their core purpose.
No word on whether the 2.5-liter will be standard or available only in special editions like the BRZ STI, but as it stands the Japanese-only BRZ tS by STI has no engine upgrades.
