Toyota is attempting to keep the minivan segment alive with its Sienna, which is on its third version since it first appeared on the market. It comes equipped with a 187-hp 2.7L 4-cylinder engine, but there’s also a 3.5L V6 available that produces 266 horsepower and 245 lbs.-ft. of torque. All versions have a 6-speed automatic transmission. An all-wheel drive version is also available with the V6.
