Materials used inside the xD are generally good for a car in this price range.   The expansive plastic that covers the dash and door panels has a woven-grain, matte finish, and it's more appealing than the glossy hard stuff in some inexpensive cars.   The shiny black plastic trim pieces look like piano lacquer, and better than fake wood or metal.  

The seats are covered in dark charcoal fabric and are quite handsome, especially when compared to the cloth that comes with some other cars in this class.   The upholstery isn't plush, but it feels sturdy.   The front seats are firm but not too firm, and provide decent bolstering, which is good because some xD owners might be ripping around corners after they add Toyota Racing Development suspension components.  

Switches are well placed, with the audio system above the air conditioning controls in the center stack.   All the knobs are big and easy to find, though those for the climate controls have a slightly loose, jerky feel.  

The gauges are a mixed bag.   The primary display, which Scion calls a concentric combination meter, is a speedometer and tachometer in one package, centered over the adjustable steering column.   It's designed to be different, but in this case it's not better.   With the tachometer and speedometer needles moving in opposite directions around a circle, it's hard to process the information at a glance.   The gas gauge is a bright, easy-to-read LED to the left of the steering column, and the xD comes standard with a multi-information display that allows the driver to toggle between the odometer, trip meters, instant fuel economy, average fuel economy, distance-to-empty and average vehicle speed.  

The 160-watt Pioneer sound system with six speakers is loud and clear, and plenty for a car this size.   Dealer-installed upgrades are available for buyers who want more.   The standard system is wired for iPod, MP3/WMA, and satellite, and includes an auxiliary input jack.   Like the trip computer, the redundant audio controls on the steering wheel spoke are the exception in this class.  

The rear seat is quite roomy when rear-passenger space is maximized.   The rear seat easily slides forward or backward six inches, adding space for either cargo behind the seatback or passengers in front of it.   With the rear seat moved full forward, there's enough legroom for a 12-year old; with the rear seat moved back, there's room for medium-sized adults.   Head room is expansive, and with the front seat set for a 5-foot, 10-inch driver, there was enough rear legroom for a 5-foot, 9-inch rear passenger.   Moreover, the rear seatback reclines 10 degrees, which remains a rarity in all cars.   The rear-seat headrests rise a long way from the seatback, allowing more comfort for passengers when the seat is occupied, and better rearward visibility for the driver when the seat is empty.  

Cargo volume is good, which is important if it's stuff you carry more than passengers.   The rear seat folds totally flat, opening 35.7 cubic feet of space behind the front seats.   That's substantially less than in either the Honda Fit (57.3 cubic feet) or the Nissan Versa hatchback (50.4).   Small compartments under the xD's cargo floor hold the jack tools and leave some extra room, though not enough to hold and hide a laptop.   A cargo blind to cover whatever is behind the seats is available from Scion dealers.  

Small storage areas are plentiful in the xD, or at least in the forward half of the interior.   There's a 5.3-liter upper glovebox and 5.7-liter lower glove box.   There's a box in the center console between the seats, a small compartment for change, a small storage tray that slides out of the dash, and five cupholders, including two molded into the hard bins at the bottoms of the doors.   There are no pockets on the seatbacks, so it's a different story for rear passengers.   They get a cupholder molded into each door and a third at the rear of the center console.  

We found the air conditioning works well.   The interior is airtight.   With just the driver's window slightly open, there's a thump in your ears, so you have to crack a second window to let the air out, common in many cars nowadays.   Much sound-deadening material has been used in many places.   The xD is not the quietest small car around, and it's one of the noisier Toyota products we've tested.   But with that excellent Pioneer stereo blaring, you may not notice.
