Nissan bills its GT-R as a “multi performance supercar” that delivers fantasy driving.

It's also something else: the most expensive vehicle to insure of 300 considered in a study by It's average annual premiums were $2,533.

The GT-R's supercharged engine helped drive it to the top. It's a 3.8-liter twin-turbocharged 24-valve V-6 with 485 hp. Compare that with the 71-hp Smart Fortwo, the smallest car available in the U.S. and one of the least expensive to insure

Owners of the GT-R buy it for power and speed, and their driving habits will be reflected in frequent and expensive insurance claims, says

GT-R owners who are young with less-than-spotless driving records could easily see their annual car insurance premiums zoom to several thousand dollars.

Sports cars, including the Dodge Viper and BMW M6, dominate the “most expensive” roster, along with theft favorites such as the Cadillac Escalade.

If vehicle shoppers are looking to lower premium costs, the “least expensive” list contains a good selection of SUVs, minivans and passenger cars. Low insurance rates tend to reflect a vehicle's safety because drivers of those models have submitted fewer and less-expensive insurance claims.

Enjoying the bottom spot, with the lowest average car insurance rate, is the '09 Hyundai Santa Fe, an SUV, costing $832 a year.

It's followed by the Kia Sportage SUV and Hyundai Entourage minivan.
