飞行汽车可能比公路汽车更有效率，这似乎有些疯狂，尤其是在传统飞机以耗油著称的情况下。一辆小型四人座汽车不是波音737，其油耗会低很多。

让一辆汽车飞起来的方法有很多，但大多数都太麻烦而无法快速起飞。根据垂直起降(VTOL)飞机的物理特性，这项研究可能是最有希望的选择。这些节能创新使巡航变得轻而易举，但它们对起飞、盘旋或着陆没有多大帮助，而这些东西本质上仍然效率低下。

因此，尽管VTOL飞行器仍可用于城市内短途旅行和送披萨，但它们无法解决能源危机。最后,天气很重要。35英里/小时的顺风会减少15%的电力消耗和排放，而35英里/小时的逆风则会增加25%。在遇到合适的着陆地点之前，必须携带额外的重型电池，以避免电池耗尽的潜在灾难，这可以抵消排放节约。

Flying cars may be more efficient than road cars, which seems crazy, especially when traditional aircraft are known for their fuel consumption. A small four-seater car is not a Boeing 737, and its fuel consumption will be much lower.

There are many ways to get a car to fly, but most of them are too troublesome to take off quickly. Based on the physical characteristics of vertical takeoff and landing (VTOL) aircraft, this study may be the most promising option. These energy-saving innovations make cruising easy, but they don't help much with take-off, hover or landing, which are still inherently inefficient.

Therefore, although VTOL aircraft can still be used for short-distance urban travel and pizza delivery, they cannot solve the energy crisis. Finally, the weather is very important. A 35-mile/hour downwind reduces power consumption and emissions by 15%, while a 35-mile/hour upwind increases by 25%. Additional heavy batteries must be carried before a suitable landing site is encountered to avoid potential catastrophes of battery depletion, which can offset emission savings.（文编译/飞行汽车 www.feiauto.com）
