⑥ Tesla Concept S (teslamotors.com)
Though it may not look like it, the Tesla is designed for families. Thanks to its hatchback design, it boasts seating for up to five adults and two small children in a small rear seat. But best of all, the battery on the Tesla S, which is expected to hit car lots sometime this year, can get you up to 300 miles on a single charge and you can swap out battery packs for longer trips or recharge one in about 45 minutes. It also comes equipped with touch screen controls and Web connectivity inside. Um, remember when this was the only means of transportation for a family vacation?
