Half SUV and half wagon, the Toyota Venza is crossover in the purest sense, and it's known nothing but success since it launched in 2010. The 2.7-litre 4-cylinder engine is good enough for most jobs, but it may leave you wanting if you need to hitch a trailer. For more power, opt for the 3.5-litre V6 that can tow up to 1.587 kilos (3,500 lbs.).
