If bigger is better, and Range Rover is the best of the best of SUVs, then the best is yet to come. We got these spy shots of a minimally cladded long-wheelbase Range Rover testing, which looks like it's probably mere months away from the showroom. Expected to be offered worldwide, the long-wheelbase Range Rover is expected to be most popular in Russia and China, where many are chauffeur-driven and where second-row comfort is a top priority.

The wheelbase stretch is expected to be approximately 6 inches, bringing the total wheelbase to 121 inches, or slightly longer than the standard-wheelbase Cadillac Escalade, and almost identical to the Mercedes-Benz GL . Despite the added length, which would seem like it would facilitate a third row, it's unknown if the long-wheelbase model will be a two- or three-row model.

Powertrain options are expected to remain the same as for the standard-wheelbase Range Rover, including the 510-hp supercharged 5.0-liter V-8. Although the 2013 Range Rover is still offered with JLR's 5.0-liter naturally aspirated V-8, it is expected to adopt the supercharged 3.0-liter V-6 as the base engine for 2014. The LWB model may or may not be offered with the V-6 in the U.S. market.

This is the first long-wheelbase Range Rover variant since the County LWB version of the first-generation Range Rover went out of production in 1996. It was briefly sold alongside the newer second-generation Range Rover, which went on sale in 1994. The fourth-generation Range Rover is comparatively enormous compared with the petite first-generation model, which rode on just a 100-inch wheelbase with an overall length of 176 inches. The current standard-wheelbase Range Rover rides on a 115-inch wheelbase with an overall length of 196.8 inches.
