Land Rover’s improvements to its latest Range Rover and Range Rover Sport are impressive, to say the least, and this is reverberating in the marketplace where the vehicles are generating waiting lists up to four months long. The information was revealed to Edmunds by Land Rover vice president Kim McCullough.

"Depending on where you are in the country, I would say the average is about a four-month wait right now for those products," she is reported to have said.

Such lengthy waiting lists are usually associated with niche sports cars but for a brand selling luxury SUVs it shows how powerful good design and engineering can be for an automaker when it comes to influencing the popularity of its models—the Solihull plant in the U.K. where the vehicles are built is currently running 24 hours a day, five days a week to keep up with demand.

Sales of the Range Rover in the U.S. increased 56 percent last year, to 12,221 units. Worldwide, the Land Rover brand's total sales numbered 348,338 units in 2013, up 15 percent.

To keep the momentum going, Land Rover will introduce a new long-wheelbase Range Rover variant later in the year, and further down the track we may see new hybrid versions of the Range Rover and Range Rover Sport as well as a high-performance Range Rover Sport R-S.
