I am trying to decide which car to buy. It's between the new Crosstrek and Impreza. I've driven both of those as well as the Forester. All of them apparently have the same 2.0 motor. So my question is, why is the Crosstrek noticeably lacking in torque from a stoplight? I would like to buy the Crosstrek, but with the lack of power I'm strongly considering the Impreza (especially considering the better gas mileage rating).

 

Any insights? Thank you!

If all those has the Same 2.0L FB engine, the difference should be due to Different Body Weight.

 

 

 

Kind Regards.

Tire size, vehicle weight, and final drive ratio all play a part in the way the car accelerates. The Crosstrek has bigger tires, and more weight, which will slow it down off the line. Final drive ratio in the CVT may be the same, but in the manual trans they had to go from a 4.11 in the Impreza, to a 4.44 in the Crosstrek to help counter the affect of the weight and tires.

The Forester comes with the FB25 (I guess that's the correct engine code?). The Imprezas are smaller and come with the 2.0. I'm not sure about the final drive on the CVT either but I would guess they would have given it a lower final drive for the bigger tires. I wouldn't see weight being an issue, I believe it's within 50lbs of the stock Impreza. Maybe it was just that particular car? Impreza had more miles, maybe the engine was better broken in? I would have thought they would have given it a different cam too for more low end torque considering what market it's aimed at but I doubt they'd bother with that.
