When it comes to auto insurance, speed costs.

The most expensive 2015 model vehicle to insure in the U.S. is Nissan Motor Co.'s 600-horsepower, $150,000 GT-R Nismo, at an average $3,574 a year, Insure.com said Tuesday in a statement. The 621-horsepower Mercedes-Benz SL65 AMG convertible and the 645-horsepower Dodge SRT Viper held the next two spots.

Expensive vehicles cost more to repair and "the people who buy the cars that are made for speed are going to want to try them out sometime," Penny Gusner, an analyst at the information website, said in an interview. "The likelihood of them having a more severe crash compared to the soccer mom driving 35 miles an hour (56 kph) in the neighborhood is a lot higher."
