After it was confirmed that the turbocharged Subaru BRZ won’t arrive in the foreseeable future, we now get some idea of what type of power the model will later offer. The first turbocharged variant of Subaru’s 2.0-liter, FA-series flat-four engine – the naturally aspirated version that powers the BRZ and its Toyota/Scion brethren – has been tested on the renewed Japanese-market Legacy sedan and wagon.
The turbo FA20 generates 296 hp and 295 lb-ft of torque. When used in the JDM Legacy, the engine is bolted to Subaru’s CVT, probably for better fuel-economy. It’s expected that a turbo BRZ will be equipped with a proper manual transmission and an auto that’s comparable to what it presently uses.
The new turbo FA comes with Subaru’s own direct-injection setup. This is very different from the BRZ’s Toyota-derived direct- and port-injection heads.
2013 BRZ is already impressive with its rear wheels offering 200hp but with 300hp, the fun factor just got higher. If we put aside the uncertainty with the Turbo BRZ, it’s likely that this engine will be available within one or two years inside the next-generation WRX and STI.
It has been announced previously that the sporty models will be powered by a turbocharged iteration of the 2.0-liter FA motor and also that the STI’s engine will offer higher than 300hp. The 2.5-liter turbo in the current 265-hp WRX and 305-hp STI will be replaced by the new 2.0-liter turbo four.
However, the idea of a 296hp WRX and a more powerful STI seems outstanding. The chances are that the WRX will produce somewhat less while the STI generates slightly more. The obvious reason for Subaru’s decision for the smaller 2.0-liter turbo to power the WRX and STI is fuel economy. The 2.5-liter being used now is not quite frugal enough.
Body performance and chassis have been tremendously modified so that drivers can better handle the total speed of combining a turbo Boxer engine and Symmetrical AWD.
Attempting to harden both body and suspension while enhancing suspension geometry has both sped up vehicle reaction to driver steering input and set higher the performance limit for cornering. Furthermore, Multi-mode Vehicle Dynamics Control (VDC) and Active Torque Vectoring have been included for a more controllable and fun driving experience.
A lot of hours of in-depth suspension tuning have ended in a comfortable and flat ride.
Engaged with a firmer steering gearbox, the electric power steering mounts for a more direct steering feel and improved fuel efficiency.
This is the first instance that a manual transmission vehicle has been partnered with the DIT Boxer engine. Another noticeable feature is that the new optional Sport Lineartronic offers a superb shift response for a ride that is sportier compared to the previous Lineartronic applied for higher torque. This means that more drivers can get outstanding environmental confidence that goes with an actual sports driving experience.
Six-Speed Manual Transmission
The gear stick ratio and gear ratio have both been enhanced from the five-speed transmission to get a better driving feel and smoother gear shifting to partner the sporty characteristics of the WRX.
By making the gear ratios wider than the previous five-speed manual transmission model to make engine speeds at bay, it has improved fuel economy and has limited vehicle noise while driving at high speeds.
