I saw this vehicle on my way to school this morning and stopped to ask the driver about it. He didn't speak much English, but I took notes and then found more information on the Internet.
This car is made by Ligier Automobiles, a French company. Guy Ligier was a Formula One racer and later Formula One team owner. He started the company, which is now owned by Piaggio. This particular model is in their "Fun Range" line, and is called the "Be Two." Is not considered a car, but is a "quadricycle." According to the owner, drivers do not need a drivers' license to operate the vehicle. However, according to the website, the driver needs to be at least 16 years old and have a class B1 license (I don't know what that is).
The driver also told me that the vehicle is powered by a two-cycle engine made by Lamborghini, however the website does not verify this. The maximum allowable speed is 45 mph, although the driver informs me that it will go faster than that. It weighs 340 kg, which is 748 lbs. It gets 45 mpg.
Also, I updated the post titled "How's this for sporty?" because I got more information about the little gray car.
