不会啊~我看了下,灰常结实·····不信你谷歌一下~~~~绝对吓着你~
没错.
Can a car this narrow really be safe?
Looks are deceiving, because the Tango may actually be the safest car on the road!
The most important safety feature of a car is its ability to avoid an accident in the first place. With 2,000 lbs of weight under the floor (achieving a 5-star NHTSA-calculated rollover threshold) the Tango was able to negotiate the emergency lane change maneuver—(Moose Test)—conducted by Consumer Reports at the Automotive X-Prize competition in 2010, at a higher speed than any other car or motorcycle tested. What this means to you, is that you can get out of trouble, or avoid an accident better than any other car. Barely over half as wide as a typical car, the likelihood of a head-on is reduced dramatically. If, for example, you're next to a semi truck that moves into your lane, with all of the extra room to move over, and the extra acceleration, you can get out of the way better than any other car in existence. Furthermore, the extreme weight to size ratio, as compared with other vehicles, makes it less affected by wind, or turbulence created by semis.
The Tango's race car roll cage was designed by Prodrive, famous for their management of the BAR Formula One team, and multiple world rally championships in the Subaru WRX which they designed.
The Tango cage design was submitted to FIA (Federation Internationale de L'Automobile) for certification, which it passed. Consequently, the Tango cage is precisely the structure required for racecars exceeding 200 mph. Sports Car Club of America (SCCA) requires a single removable door bar to be held by 3/8" pins in double shear. The Tango has double this requirement, with two additional horizontal bars, with specially-designed hinges machined from billet stainless steel. In addition to those there are four vertical bar segments forming a structure that ties the single factory bar to the 2 additional horizontal bars. There are literally over four times more side door protection bars than found in the largest SUVs.
Doors are also thicker than on a typical car because of the added roll cage protection. Having windows on both sides, making both sides the driver's side, increases visibility and reduces blind spots.
How fast can the Tango maneuver?
In terms of maneuverability, the Tango has the ability to quickly move out of the way in case of emergency, even fitting between other cars and lanes. It also has an instantaneous and powerful acceleration, better than almost any other car. It brakes quickly, so the maneuverability to avoid a collision is probably better than any other car as well. Even though a motorcycle has an equally small footprint, it cannot be maneuvered as quickly if an unexpected object comes into its path. This is because a motorcycle has to countersteer in order to react to an emergency, which costs valuable reaction time. Motorcycles do extremely well racing on road courses where they can plan ahead, but that is far different from reacting to an emergency situation.
What about rollover potential?
Rollover is a great danger for many vehicles and the Tango, being so narrow, might appear to be unstable. However, because of the batteries and additional ballast just 4" off of the ground, the Tango has achieved a NHTSA 5-star equivalent static rollover threshold rating. This is approximately 56%—or as an example, about the same as a 911 Porsche. In fact, the Tango has stability that exceeds that of most sports cars.
