Were looking at buying this vehicle early next year, after my second child arrives. This would replace a sedan, and needs good space for a family of four. The Prius v looks better than most midsize SUVs, and my Focus 3-door got me addicted to the utility of hatches. However, I find the listed horsepower numbers worrying. We would regularly be moving 400lbs of adults, plus two children, plus all the required kids stuff. I plan on keeping the car 7-10 years, so this means kids up to 13 and 10 years old, so mid-size kids and all their sports+school stuff. I know people are going to say you can get by with 20hp and smart driving, but I dont feel that is the case where im at. In the chicago suburbs, people regularly do 80-90 on the expressway, and I need to haul this family from a 25mph ramp to merge into 80mph just about every day. Then maintain that speed, and the ability to quickly slow and speed up without getting rearended or merged into. So, does the Prius v have the power to back up the space? I also looked into the Mazda5 and Elantra Touring, and again the low power numbers worried me.
