For 2015, the Toyota Sienna gets a refresh. It doesn't look much different on the outside (updated grille and taillights), but under the skin there's a revised suspension, a stronger body structure and welcome improvements to the interior's design and materials quality. Toyota Sienna comes with a 3.5-liter V6 engine that delivers 266 horsepower and 245 pound-feet of torque and drives the front wheels through a six-speed automatic transmission. Antilock disc brakes, stability and traction control, front-seat side airbags, full-length side curtain airbags, a driver-side knee airbag, a front passenger seat cushion airbag, active front head restraints and a rearview camera are standard on all 2015 Toyota Sienna models. We've long been impressed by the Sienna's V6 engine and how it delivers lively acceleration whether you're bopping around town running errands or getting up to cruising speed on the freeway. The six-speed automatic transmission does a great job of keeping the engine's thrust on tap, yet the Sienna still manages to provide respectable fuel economy, provided you're not too aggressive with the gas pedal. The SE's recalibrated suspension and steering give it even more agility around turns. This is seven-passenger Sienna.
