whats the point of the 2.5ltr engine?
looking at the new stats for the car the WRX's have identical 0-60's (5.9 / 6.1 wagon), the top speed has dropped by 1mph for the saloon & remained the same for the wagon (143mph), yet the fuel consumption is even worse at 27.4 (was 30.7). now just 14.4mpg around town!

The amount of people who have fitted 2.5 to there car and got good bhp and torque figures means that it would be a great car to modify as it has the 2.5 already fitted and thats one less thing to have fitted, if your like me and spend every penny on the car.

Figures don't mean much though. I'd expect the 2.5 to be alot more tractable around town without the need of making sure the revs are past 3000rpm ...something figures will never show.
Subaru's mpg has always been over optomistic...I'd guess this time round they might being more honest/realistic Then aginan it maybe a load aof crap (which IMO all Subarus are anyway )

In my dealer the other day the lad I was speaking to reckoned it was more to do with Subaru standardising production. America needs 2.5l because of bad fuel apparently. They had a new WRX in and he reckoned it drove like an 03 WRX without PPP.
On a side note, the rear lights were awful!

I have an STi4 with a 2.5 fitted to it. It is my eighth Impreza, and quickest.
The 2.5 is a completely different beast- I rarely feel the need to use any more than about 6000 rpm, so much so that when Bob mapped it he asked if I wanted a WRX redline or an STi 8250. I went for the WRX, although its an STi engine I wanted the safety margin.
Before Bob mapped it the car was quite smooth and, although rather flat, quite quick- about as quick as my mate TKH's STi5 RA. I had no confidence in the map as it had been done by someone that I have no confidence in- many of you will know who I am talking about.
Now Bob has mapped it, she is bloody phenominal, very quick on track and quite smooth around town- big power, but the low down torque makes a major difference.

Emissions are something that will be affecting us more in the coming years, and will no doubt incur extra expense to many of us anyway.

Emissions is the name of the game. Every car has to satisfy emissions regulations. Ultimately it does not matter how efficient the engine is, so long as the emissions standards are satisfied. It is easier to meet both high power outputs and stricter emissions regulations with large engine displacements. That's why there is a move from 2.0 to 2.5 litre engines.

no no no subaru have made the new cars 2.5L so we all jump out of our 2.0L sti's an wrx's coz they aint cool no more much in the same way we all did with our sti 7's got an ugly bug eye dont worry this one's nicer an better and so on an so forth want shafting every 2 years to make it look like uve got an old model thats only a few months old buy a subaru they know how to shaft folk

The car is a better car, Subaru have made a commitment to enhancing the Impreza and have made radical (in some people's eyes) changes, not because they want to shaft you - because it works!

The fact is as most people have stated.
The 2.5 engine was released due to emissions! Its nothing to do with being a better car.
The 2.0 litre flat 4 is awesome, always has been and always will be. Its just easier for Subaru to make a bigger engine with the same power that produces less emissions than it is for a smaller engine.
As far as I know, there is some sort of new "emissions bill" or something coming out in January 2006 that forces cars made after a certain date to conform to these new limits.
I might just be talking b0ll0cx but thats what i've read and have been told

Ok, I agree with that.
All im saying is that, they wouldn't of used th 2.5 unless it worked out cheaper to get the right standard of emissions due to new standards shortly to be released.
BTW, anyone watching the boxing on sky sports 1 now? im not usually much of a boxing fan but this fight (hunter vs pickering) is bl00dy awesome!
