The 2018 model year Prius Eco ranks as the second most fuel efficient gasoline-powered car available in the US without plug-in capability, following the Hyundai Ioniq Blue. The Prius first went on sale in Japan in 1997, and was available at all four Toyota Japan dealerships, making it the first mass-produced hybrid vehicle. It was subsequently introduced worldwide in 2000. The Prius is sold in over 90 markets, with Japan and the United States being its largest markets. Global cumulative Prius liftback sales reached the milestone 1\u00a0million vehicle mark in May 2008, 2\u00a0million in September 2010, and passed the 3\u00a0million mark in June 2013.

This saves you from having to waste time charging your car in the future."}, {"role": "user", "content": "Interesting, I didn't know that.  I have never driven and electric car, have you?"}, {"role": "assistant", "content": "I test drove one when I was looking for a new car, but didn't buy it. The government will give tax exemptions for HEVs, so I wish I had bought the other one. "}, {"role": "user", "content": "I want to test drive one too, maybe a Tesla that is a car that I like.  Do you think you can save money driving an electrical car?"}, {"role": "assistant", "content": "Teslas are great. The Model S has a combined feul economy of 104 miles/gallon equivalent, which will save a lot of money in the long run. "}, {"role": "user", "content": "Great, but I think I will go with a model 3 that is smaller and cheaper,  I believe the model S is too big for me.  Would you consider buying an electric car in the future?"}, {"role": "assistant", "content": "It depends. I like the idea of saving money and helping the environment, but the car I tested felt clunky to drive.  Maybe if I tried a Tesla, I'd be more likely to purchase"}]
