Vehicle Overview
Toyota is back in the minivan race with an updated 268-horsepower V-6 powering the 2007 Sienna. That leapfrogs other minivans like the Honda Odyssey and Kia Sedona, who trumped last year’s Sienna with engines pushing 250 hp.
Toyota introduced the current, second-generation Sienna minivan for 2004. Optional all-wheel drive and a refined, upscale interior are among its traits.
Siennas are available in four trim levels: CE, LE, XLE and top-of-the-line XLE Limited. All-wheel drive is available on the three upper-end models. CE and LE minivans come in seven- or eight-passenger configurations. Toyota extensively refreshed the Sienna’s front end for 2006, so changes other than the upgraded engine are minor.
Exterior
Similar in appearance to prior models, the current Sienna rides a 119.3-inch wheelbase, measures 200 inches long overall and stands 68.9 inches tall. Standard wheels measure 16 inches in diameter, but the XLE Limited and models equipped with all-wheel drive have 17-inch tires.
Upscale features include puddle lamps and power-folding side mirrors on XLE Limited models. Power sliding doors and a power liftgate are available on uplevel trims.
Interior
Two second-row seating choices are available. The seven-passenger configuration features second-row captain’s chairs; the passenger-side chair can be moved side to side, permitting either a bench or bucket seat arrangement. For eight-passenger seating, CE and LE models can be equipped with a three-way split-folding bench seat in the second row. In eight-passenger Siennas, a “Front and Center” middle seat can move nearly 13 inches closer to the front seats, making infants in child-safety seats more accessible. Cargo volume totals 148.9 cubic feet behind the front seats and 94.5 cubic feet behind the second row.
A standard 60/40 “Split & Stow” third-row bench seat folds flat into the floor. Either side of the seat can be stowed separately. Available equipment includes laser cruise control, a navigation system with a rearview camera, and sonar-based front and rear parking assistance.
Under the Hood
Toyota’s new 3.5-liter V-6, which now sees duty across a number of vehicles, replaces the 3.3-liter V-6 in last year’s Sienna. Power is up substantially, to 268 hp and 248 pounds-feet of torque. Last year’s engine made just 215 hp and 222 pounds-feet of torque — near the bottom of the pack for today’s minivans.
A five-speed automatic transmission is standard.
Safety
Antilock brakes are standard, and Vehicle Stability Control with traction control is available. Side-impact airbags for the front seats and side curtain airbags that cover all three rows of seats are standard.
