The latest generation of the Sienna minivan ditched the V6 and went hybrid only. The system combines a 2.5-litre four-cylinder engine with one or two electric motors depending on your choice of FWD or AWD. Total output is rated at 245 horsepower. Despite weighing more than two tons, the Sienna achieves a remarkable 6.6 L/100 km. Need to tow a trailer? That’s still possible up to 3,500 lbs. Like any Toyota product, safety and reliability are part of the package, too.
