The Toyota Sienna is the only 2007 minivan to offer AWD and a 250+ horsepower engine.  Along with being the most powerful and perhaps the most capable vehicle in its class, the right trim package will also make it one of the most luxurious.  Lately, more Lexus technology and features has started to appear in the upscale Toyota models.  The family-friendly Sienna exemplifies these additions with the XLE Limited.
The Sienna price spectrum varies by about $10,000 from end to end, beginning with the base CE and ending with the XLE Limited.  Even the CE is well-equipped, with standard features like power windows, front and rear air conditioning, power mirrors and locks, a CD changer, and keyless entry.  The Limited will add xenon  headlights, 17 inch wheels, a ten speaker JBL audio system, moon roof, leather seats with heated fronts, a wiper de-icer, and adaptive cruise control.  The Limited is one of two models eligible for the DVD-based navigation system.  This includes Bluetooth and rear backup camera.  The Limited is the only model with front and rear parking sensors.
Both seven and eight passenger seating configurations are available, as is 2WD or AWD.  All Sienna models use the same 3.5 liter V-6, which is new this year.  The V-6 provides 266 horsepower and 245 pound-feet of torque, and is teamed with a five speed electronically controlled automatic transmission.  Toyota's VVT-i system, found in all their vehicles, also draws additional power from the engine, while minimizing emissions and improving fuel efficiency.  The 2WD Sienna has an EPA rating of 19/25 mpg.
