Currently in its second incarnation, the massive Volkswagen Touareg SUV shares its roots with the Audi Q7 and the Porsche Cayenne. Under its hood, there's a 3.6-litre 280-horsepower V6 or an optional 3.0-litre turbodiesel with an impressive 406 lb.-ft. of torque. It can tow up to 3,500 kilos (7,716 pounds). Regardless of the version you choose, the 8-speed automatic transmission and all-wheel drive come factory standard.
