After 13 years of using the Impreza sedan platform for the WRX/STI, Subaru change direction and released the MY08 "Ugly Betty" hatchback Impreza.

Some say they have SOLD OUT and gone mainstream, softened the WRX image to sell to the masses, especially those in the USA.

But how soft in Performance terms have they actually evolved the Impreza WRX/STI into over the years...lets see:

so am i right in thinking 206kw is 280bhp??

i am trying to work out kw and bhp differnaces thats all

0.746 Kw = 1 Bhp

206kw = 276 Bhp

cheers thats what i though i just said 280 refering to std power i meant 276

so the 08 is only just catching the MY99 in 1/4 mile times? shows the old power to weight ratio coming into play.tis a pity there is no accurate test of each yera in lap times, the chassis differences are pretty huge

be a nicer comparison with the JDM 2.0L's though

are they really that underpowered oz official cars???

compared to there jdm cousins....

aus cars are offseting the torque with a 2.5 litre.

hp per litre, the non-jdm cars are down.

Seems Subaru have finally woken up to themselves with the release of the 09 WRX Sedan.
Its interesting to note that the 09 WRX now has identical power and torque figures to that of the EJ207 02-->05 STi but carries 75 Kg less weight and has dual AVCS for a better torque spread.

09 WRX will be good Bang for the Buck again me-thinks!!!!
