An energy efficient Ford F-150
certainly sounds like an oxymoron, but the folks at Protean Electric have proven that even this gas guzzler can go green. So how'd they do it? Well, with in-wheel motors
of course. This isn't the first time we've seen this technology put to use
, but if things go according to plan, Protean's version of the in-wheel motor could be road ready as soon as next year. The things weigh 68 pounds (31 kilograms) a piece and offer 110 horsepower per wheel. When pared with this F-150 -- rocking a custom battery -- they offered up 100 mile-per-hour speeds and a range of 100 miles. That might not be enough to take you across the great state of Texas, but it's certainly sufficient for tooting around the ranch.
