Honda civic SI vs Lancer Evo?

Pros and cons. Which is ultimately better. Also HP difference.

The stock Civic Si is a much less powerful vehicle than an Evo of any year.

The Evo for this year has about 50% more HP than the Si (approx. 290 vs. 200 respectively).

Lancer Evo

Model year?

Depends on your needs/desires, really. An Evo will beat an Si in virtually all performance aspects except maybe for auto-crossing purposes.

Personally, I think AWD is simply extra weight and gives a false sense of security in winter driving, but I'd still rather have that over a FWD platform when it comes to street performance.

If you have the budget for either, I'd go with the Evo. It has all wheel drive, and likely ~ 100 more horsepower.
