As mentioned if the climbs are really steep you can use Mountain Mode or just put it in HOLD. That reserves sufficient power, allowing the battery to work with the engine, which provides more peak power for climbs. Usually don't need it for most climbs. Would be unusual to need it on major roads because the grades are usually lower. Again, it's peak not average power. Keep in mind that the 1.5L engine in the current generation Volt can most likely provide most of the power you need. The first generation Volt had a 1.4L engine, so the shortfall was greater.
Noise is interesting. At higher speeds there is more road and wind noise than engine noise, so the difference between an ICE and an electric vehicle is pretty minimal. You'd see a bigger difference at lower speeds. Passengers in the Volt can't tell when you switch from the battery to the engine. You may be able to tell because you get a bit of engine vibration through the steering wheel.
I believe you're mistaken about the size of the cargo area. It's double what you're looking at. Plenty of space for most things. With the seats down, if you can get something through the opening you shouldn't have any issues.
Legroom for the front is luxurious and there is more than ample headroom. I'd be surprised if you have a problem. It's the back which might be challenging. I couldn't sit back there, but I can't sit in the back of a Model S either (different problem same result). The only way to see how this works for you is to go in person and test it out.
