The Touareg SUV was originally launched back in 2003 and then significantly updated in 2010. It majors on luxury, although it also has the capability to tackle more extreme conditions than most drivers will ever experience. The latest version is much lighter than the original, despite being bigger. That weight reduction means a notable improvement in fuel economy across the range. The Touareg Hybrid is new, although the TDI diesel engines still offer the best blend of economy and performance.
