Just a few thoughts to add to this conversation. We recently purchased a 2015 Crosstrek Premium with EyeSight and had the dealer add after-market leather. Our runner up was the HR-V. The Subie AWD pushed us toward the Crosstrek. We love to hike, camp, and ski. Here are my comments about both in different areas:
Exterior Appearance:
Both look good. I think the HR-V looks much better than the CR-V, and i think the Crosstrek looks better than its Impreza siblings. I appreciate the roof racks being standard on the Subie. Tie.
Interior Appearance:
I think I expected less from the Subie and more from the V, so I was disappointed with the V's interior. It's weird things, like the door panels in the V seemed like something from a 70's budget car. But the plastic in the Subie didn't bug me. The Subie also seemed more open inside, I think due to more consistent headroom throughout the cabin. The V had "cut-outs" in the ceiling to add headroom, which is fine, but that left other parts of the ceiling a bit lower. That design, coupled with the straight-drop door panels, made me feel like I was in a cave in the V. Slight win for the Subie.
Comfort:
Both have fairly basic seating. The Subie does not have a power seat option or lumbar adjustment. Win for the V.
Interior Function:
The magic seats for the V are wonderful. More vehicles should do that. The rear hatch seat releases were also a nice touch. Everything works nicely in the Crosstrek, but nothing stands out like it does in the V. Solid win for the V.
Interior Space:
In terms of seating space, the usable headroom, legroom, and kneeroom is significantly better in the Subie. Our son is 6'6" and fits easily in the front or back seat of the Subie with room for another adult either in front of him or behind him. That is not the case in the V. Moreover, those ceiling cut-outs in the V really make it so he feels like his head has to be in a certain spot in the vehicle for it to work for him. In terms of storage space, both are good. I think the V has slightly more cargo room, but not enough to make a functional difference. Solid win for the Crosstrek.
Electronics:
We got the upgraded 7" infotainment system in the Crosstrek. In my eyes, it was nicer and more user-friendly than the system in the V that we tested. The backup camera was also bigger and nicer than in the V. I liked the blind-spot warning in the V but also appreciate the lane departure warning and adaptive cruise on the Crosstrek. Slight win for the Crosstrek.
Gas Mileage:
I get 36mpg on the highway with the Subie and 27mpg in city, with moderate driving. With "hard" driving, I get 25mpg in the city and 33mpg on the highway. I think the V probably beats it, but not by much. I'm averaging 29mph overall in the 3 weeks I've had it (mostly city driving so far). I've been pleased (last vehicle was a 4Runner; so this is a major step up in gas mileage). Based on reports, slight win for the V.
Acceleration:
Ouch. Neither one is particularly impressive. However, both have enough zip to get to highway speed and merge/pass safely. I saw a number of reviews that criticized the Crosstrek for being under-powered but then praised other vehicles that had even worse acceleration. I'm here to tell you, I'd like more oomph, but it really isn't bad at all. Tie.
Driving Quality:
Both my wife and I preferred the feel of the Crosstrek. Both are very competent drivers. I felt like I had better visibility in the Crosstrek. Slight edge to Crosstrek, but YMMV
Ride Quality:
Both were actually pretty good. I think the V is even a little smoother than the Crosstrek, but but are comfortable and composed when on pavement. Maybe a slight edge to the V.
Reliability:
Subie has overtaken Honda in Consumer Reports, despite some fears I saw earlier about oil consumption. FWIW, our Odyssey has an ongoing oil consumption issue that the dealership has been unable to resolve, but I still think the Odyssey is the best minivan on the road. The Subie has been out for three model years. This is the first year for the V. I have slightly more trust in the Crosstrek, but both should be good. Tie.
Safety:
With EyeSight, the Crosstrek is a Top Safety Pick Plus and has a 5-star crash rating. The V also gets a 5-star rating and is a Top Safety Pick. Maybe a very slight win for the Crosstrek.
Other:
As noted initially the Subie AWD was a nice plus for us.
And that's what I've got. I think both are nice vehicles in the segment. I enjoy my Crosstrek, although the HR-V was tempting. I think the V is better-suited for some folks and the Crosstrek is better suited for others.
