The 2007 Toyota is Sienna is the most powerful minivan in production, and it is also the only one available with all wheel drive.  The Sienna gets a more powerful engine this year, and some interior amenities have also been added.
The LE represents the second tier in the Sienna lineup, with respect to both price and features.  LE models offer an in-dash CD changer, heated mirrors, full power accessories, cruise control, and keyless entry, all as standard equipment.  The exterior is differentiated from the base CE by the addition of a roof rack and privacy glass.  Popular options are the rear seat DVD entertainment system, power doors, and a JBL audio system with an in-dash CD changer.  All options are grouped into numbered packages, so it is not possible to pick and choose individual desired features.
The Sienna is now equipped with a 3.5 liter DOHC V-6, which provides 266 horsepower and 245 pound-feet of torque.  The new engine is supported by Toyota's Variable Valve Timing + intelligence technology, and mated to a five speed electronically controlled automatic transmission.  The addition of AWD pulls fuel efficiency down from 19/25 to 18/23 mpg.  The AWD package also includes run-flat tires, 17 inch wheels, and a windshield wiper de-icer.
