( http://www.TFLcar.com ) Let's face it the 2013 Audi Allroad and the  Lexus RX 350 will spend more time traversing American shopping mall parking lots than bouncing over boulders in the great outdoors. But the Audi is called an Allroad and the Lexus has a locking differential so perhaps these vehicles can venture off-road. we decided to find out in this TFLcar Off-Road Mashup Drive & Review. Which of the two is the most off-road worthy and which of the two should you buy if you happen to cross shop the two modern vehicles.
