WRX and WRX STi

[InfestedShadow]

what's the difference between both cars ?

[freakray]

WRX - 2.0 turbo 227 hp
STI - 2.5 turbo 300 hp

There are differences in the exterior and interior trims between the cars too.

Those are the figures for the North American models, the WRX and STI available in other countries have different figures.

[InfestedShadow]

ah cool, and the Sti have 6 speed instead of 5 right ?

[Right_LiRrr]

Yes. All new STi's come with 6-speed and WRX's with 5-speed (apparently too much torque to need a 6th gear ...however, I wouldn't mind a 6th for cruising in on the highways)

No offence, but as freakray suggested in the other thread, try looking at the manufacturer's website first since they offer answers to all your basic questions.

Plus the STi has a *much* better suspension package, a Driver Controlled Center Differential option, front limited-slip, rear-wheel bias AWD, better wheels, better tires, a better aero package, etc. STi = WRX, but with everything better.

I thought all AWD Subarus were RWD-biased. Even if only nominally...

Other way around.

They're FWD biased, the auto is more biased than the manual.

Excepting, of course, the STi

That could be explained by the fact that the driver controls the bias, not the car's computer.

[SabreKhan]

Even on "auto", it's still rear-biased in the STi.

The STi is 35/65 on auto, and can be adjusted all the way to 50/50. I have no clue about the WRX.

[SteveK2003]

I just got the Impreza book a few weeks ago (Counting the days......), I will look and see if it has any specifics.

[SabreKhan]

It's all on Subaru's website (or it was when I was buying one...)

this figures is only for North America version. The other version is:
WRX - 2.0 turbo 250 hp
WRX STI - 2.0 turbo 280 hp <--much lower than the North American one....
and i think the australia version's WRX STI only got 250hp (i heard it from somewhere else) correct me if i am wrong

Basically, the WRX STi is faster, more powerful and has better traction ability than the original WRX. It has a front mount intercooler (instead of the puny top mount one in the WRX), a bigger turbo system and boasts about 224 KW of power compared to only 169 KW with the WRX (Australian figures). In terms of appearance, it has a larger rear wing, larger roof scoop, STi fog lamp covers and bodykit.
