what is the difference between a subaru wrx and a sti

My Son just bought one of those cars. It is a WRX STI, it has a super fast engine with a bubble hood, and whale tail in the back on the trunk. Assuming there is just a WRX also made by Subaru, l guess that is what makes it a STI, The extras.

The ST l is faster/quicker than the WRX it has some engine modifications from subaru.

A turbo engine of 225 horsepower vs 300 (STI). Pricier too, plus they do not make it automatic, and larger tires.

even though the cars r related there r really too many differences to list.

the major changes are: the STi has more horsepower from the factory (and can handle more horsepower through modification), the drivetrain is different (sti has 6speed with limited slip front & rear differentials & driver controlled center differential, versus the 5spd open front differential & viscous center differential on the wrx) , suspension is different (inverted design dampers on the sti, different springs & stabilizer bars)

other key changes r HID headlights & expensive front seats in the STi, & a very large wing on the trunk

and there is about a $7000 difference in MSRP

The STi is a great car, u should buy it over the regular WRX if u can afford it

The WRX is a sporty family car, where the STi is a racecar that seats 5 people.

The STi has much stiffer suspension, a revised motor (or even a different motor in some years), a different transmission, better handling, more power, different/sportier interior, and a fairly different exterior (meaner looking, big wing, big hood scoop, etc).

Tough question here lol. The WRX is a 2.0L & the ST l is a 2.5L. The wrx runs a smaller turbo the the ST l is infamoust VF39 turbocharger. The ST l has a 6 speed transmision which is alot stronger then the 5 speed in the WRX. The ST l also has a bit more race car type look with the ''bookshelf type'' wing/spoiler on the rear, & a slightly sportier front end with a bigger hood scoop & HID light kit. There r alot of difference is between the two but if ur looking to buy there is one main point to look at; do u want a racecar or a fast 4 door sedan??

ST l is the name of the factory tuning devision of subaru
it is the fix up and fast version of the WRX.
lots of small things are different, all things that make the car go faster, stop faster, corner faster, ect.
