( http://www.TFLcar.com ) The brand new 2013 Range Rover is 700 pounds lighter than the out-going model. In a world where cars get heavier that's very unusual and that's because Range Rover used lots of aluminum in the construction premium British SUV. The 4th generation of the iconic off-road vehicle is also more posh, more dirty worthy and of course more expensive. In this exclusive TFLcar first drive review we test the new 2013 Range Rover both on and off-road to see how it drives near the Grand Canyon in Utah and Arizona. We also test the Range Rover Performance from 0-60 MPH, and we get the SUV muddy and vertical on some very challenging off-road terrain.
