First the WRX. It has the biggest

introduction of an all-new, twin-scroll,
turbocharged 2.0L 4-cylinder BOXER
engine that boasts improved acceleration,
better fuel efficiency and lower
emissions. It generates an impressive
268 horsepower and 258 lb.-ft. of torque.
The new WRX STI keeps the 2.5L
turbocharged BOXER engine that makes
it so popular, but it has been retuned
for 2015 to deliver even better throttle
response. Horsepower is a chest-pounding
305 while torque peaks at 290 lb.-ft.
And where there are engine
improvements you can also expect to
find changes to transmissions as well.
That’s because it’s the transmission’s job
to manage all the power that these two
formidable power plants produce. Both
cars come with 6-speed transmissions
-- all new on the WRX and refined on
the STI. The WRX model is linked to
a viscous-coupling centre differential
that delivers more uniform power
distribution for better traction and
sportier handling. The WRX STI version
