I drive a Prius and save a ton on gas, do you have a Prius?
Exactly, I also drive one. It's an extremely efficient car, though I forget the exact MPG it gets.
I think it is 51 mpg, is that correct? 
It sounds about right. What's the performance for the new Hyundai Hybrid?
I think it is the Hyundai Sonta, right? 
I'm not sure, but it could be. The Sonata is fairly similar in size to the Prius.
I think the Sonata gets 54 miles per gallon. 
Wow, that's impressive. I might need to trade up! What's the lowest gas mileage car out there?
I'm not sure, I think Hyundai has a lot of them, right? 
It's possible, as Hyundai keeps upping their game. I'm not really into the whole electric car trend, as I think they're not reliable enough.
