    Your next car could have two seats, three wheels — two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car{#blank#}1{#/blank#} (name) the Elio. Its two seats sit front and back instead of side {#blank#}2{#/blank#} side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car {#blank#}3{#/blank#}  (be) just $6,800. It has only one door, on the left side, {#blank#}4{#/blank#} cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it {#blank#}5{#/blank#}  (cheap). It has air conditioning, power windows and door locks and {#blank#}6{#/blank#} AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

"Whatever matters to you, this can make a {#blank#}10{#/blank#}  (different) to it," he said.
