At Frankfurt, the car being shown by Mercedes- Benz was the F 125. This car is the future because it runs on hydrogen (compressed gas) ,so its not bad on the environment! It only gives off water vapors and oxygen so there is no bad pollution! The car is also a plug-in, so you can just plug it right at home or even at a plug-in station! To the company, the mercedes is more like a "research vehicle" because it will help them work on a future where there is absoloutly no gasoline in any vehicles. Inside the car there you have controll like voice activate and even a touch pad in your controll. This car is just a prototype and probably wont be in production for like another 15 years. So be patient, the car will be here in the near future.
