The 2013 Toyota Sienna will add new standard amenities to its lineup, doing away with its four-cylinder engine, making the 3.5-liter V6 with 266 hp standard on all models.

For the 2013 model year, the Japanese automaker has equipped the Sienna LE with standard three-zone automatic climate control system, a cabin air filter, individual temperature settings for the driver, front passenger, and rear passengers, along with a separate digital control panel for the rear. The Sienna Limited and XLE model gets a standard Blind Spot Monitor, and is also available as an option on the LE model. Lastly, a standard acoustic windshield is also new on the Limited and XLE models.

The 3.5-liter V6 has an EPA-estimated rating of 18-mpg in the city and 25-mpg on the highway. The Sienna is rated to tow a trailer up to 3,500 lbs.

Available in five trims (Sienna grade, LE, SE, XLE, and Limited), all-wheel drive is now available on the LE, XLE, and Limited models. The sporty SE model features a more aggressive front end, lower side skirts, and 19-inch wheels as standard. Smoked taillights offer a cosmetic upgrade on the SE, while it sits lower to the ground thanks to its sport-tuned suspension. New for the 2013 model year, the SE gets chrome-accented door handles on the outside.

Standard on the top-of-the-line Limited model is second-row lounge seating, power 60/40 Split & Stow third-row seat, front and rear parking sonar, smart key, safety connect, and independently-powered slide opening dual moonroofs.

All Sienna trims will have the Toyota Entune system available as an option.
