In its sixth year, the 2012 Suzuki SX4 is falling a little behind the pack in refinement, but it continues to deliver accommodating seats in a well-configured cabin.
The front seats are nicely bolstered, and the driving position is upright. The seat upholstery in base models is nylong, and while it's hardly luxurious, it's surprisingly comfortable. In the rear, elevated "theater-style" seating avoids the knees-under-chin position found in many small cars and offers lots of legroom and an open, airy feel. Two adults can be accommodated, but you won't want to try three in back. The interior is largely composed of hard plastics, but at least they're good-looking hard plastics.
The trunk of the SX4 Sedan holds 15.5 cubic feet, decent for the compact class, but the bobbed tail of the five-door hatchback models (Crossover and SportBack) offers a measly 10 cubic feet with the rear seat up. They offer 54 cubic feet of load space if you put the split rear seat-back down and fill every last space, but you'll trade people carrying for cargo space.
For such a small car, the Suzuki SX4 rides well, with good damping despite its short wheelbase. Interior noise isn't too bad until you press the engine, when the car becomes positively raucous and coarse--even just in the middle of its rev range. Travel above 70 mph is uniformly loud, making long trips more tiring than they should be.
