The Elantra is rated at 29 miles per gallon city, 40 highway and 33 m.p.g. combined. Mr. Gordon said he and his wife were lucky to get 22 m.p.g. over all.

When he called Hyundai to complain, “They told me I didn’t know how to drive. They were obviously working from a script because I got many e-mails from people all across the country saying they were also getting 22 m.p.g. And they would go to the dealer, and they were told they don’t know how to drive.”

Because of complaints, he said Hyundai took him for a ride with an engineer. “They told me I drove too fast and that you could not let the r.p.m.’s go over 2,000. He never went into the fast lane, he always drove at 50, but when you are doing this at 2,000 r.p.m.’s, it takes you a half an hour to get up to 50 and it was an extremely unsafe way to drive.”

They were able to get it to 35 m.p.g. he said and every time it went over 35 they took a picture of the fuel economy read-out on the dashboard, making him feel like a liar, he said.
