The 2014 Toyota Sienna is part of the model's third generation. This front-wheel-drive minivan offers optional all-wheel drive across its five trims: L, LE, SE, XLE, and Limited. The Sienna is powered by a 3.5-liter V6 engine that delivers 266 horsepower and is paired with a 6-speed automatic transmission. The optional AWD is a rare feat among minivans, setting the Sienna apart. Key safety features include antilock disc brakes, stability and traction control, front-seat side airbags, full-length side curtain airbags, a driver-side knee airbag and active front head restraints. Infotainment options include up to a 10-speaker JBL Synthesis sound system, 7-inch touchscreen, navigation, and a rear-seat DVD entertainment system. For 2014, a Tow Prep Package became standard across all trims, increasing the Sienna's towing capacity to 3,500 pounds.
