2007 Hyundai Sonata Midsize Car Reviews & Ratings

The interior of this newest Hyundai Sonata marks a major step up the quality ladder. The overall look is clearly competitive with most in the class and better than some. Some rough edges on a few plastic molds and a less-than-lustrous finish on some dash panels are the only shortcomings we noticed.

A polished, hard-surfaced applique capped with a thin slice of chrome divides the upper and lower halves of the dash. The upper is a glare-absorbing dark color, the lower a space-enhancing light tone. The passenger airbag enclosure is seamless, mimicking the trend in higher-end midsize sedans.

As with many modern cars, the stereo head is fully integrated into the dash, making difficult any aftermarket customizing of the sound system but adding an upscale touch. Air conditioner controls are mounted beneath the stereo, within the accent trim centered in the lower portion of the center stack. Stereo and air conditioner controls are substantial, finger-friendly, intuitive knobs and buttons, with status and selections clearly displayed in their respective LCDs.

Three round dials in the hooded instrument cluster communicate the bare necessities of operational data to the driver. The largest is the speedometer, nestled inside a polished circle. To its left is the tachometer, to its right conjoined water temperature and fuel gauges. In the lower dash to the left of the steering column is a bank of five switch plugs, only two of which are employed in the U.S. version, one as an on/off for the ESC, the other the dash-light rheostat. Beyond that is a flip-down storage bin. The ignition key slides into a slot placed where it should be, in the dash to the right of the steering column instead of on the steering column itself. Easier and more elegant when starting or shutting off the car.

All models get a leather-wrapped steering wheel. Redundant controls for the audio (optional on GLS, standard on SE and Limited) are appended to the lower left-side of the hub. They are arrayed somewhat oddly, with the mode selector on top and the volume controlled by the lower two, versus the more common approach of sandwiching the mode button between the volume controls. On the other side of the hub are the standard cruise controls, with a helpful Cancel function. Hyundai says the audio controls will be improved by the end of the model year.

Outward visibility is good, although the wide C-pillars constrict quick, over-the-shoulder traffic checks for lane changing. Rear side windows roll all the way down, thanks to small, fixed, rear quarter windows that move the windows' rear tracks forward in the door, ahead of the wheel well. There's a roof-mounted, hinged assist handle inside every door.

Seats are comfortable, with adequate bolstering for the style of driving to which the Sonata aspires. The standard cloth upholstery looks and feels durable; while the Limited's leather adds a touch of class without pretending to be luxurious. The height adjustment on the driver's seat, both manual and power, pivots on the seat's front mounts, which effectively moves the seat forward as it rises. This compels taller drivers to choose between rearward seat travel and forward sightline, not always a happy compromise. On the upside, this adds inches to rear-seat legroom behind the driver, one of the multitude of measures in which the '06 Sonata bests the competition. Among the primary competitors, the new Sonata comes in second only to the Honda Accord in front and rear headroom, and to the Toyota Camry in rear-seat headroom, and by a mere one- to three-tenths of an inch. And of the second-tier competitors, the Kia Optima alone betters the new Sonata and then only by three-tenths of an inch in front seat hip room.

Rear seats are accommodating, with the bottom cushion in the center position only minimally higher than and nearly as well padded as the outboard positions. Both rear outboard seating positions have adjustable head restraints, as do the front seats. The rear seatback is split 60/40 and folds to allow the transport of long objects, such as skis and snowboards or gardening tools, depending on the weekend and season.

Storage bins and cubbies are about average for the class. Only the front doors have map pockets, and there's no compartment in the rear of the center console, which is, however, bi-level and fitted with a sliding top cover. The center console and the rear-seat center armrest provide two cupholders each. A small bin in the forward part of the center console is convenient for coins and keys, while a fuzzy-finished cubby with a flip-down cover occupies the space in the center stack below the climate control panel. A thoughtful addition is a flip-out hook in the footwell on the passenger side of the center stack to restrain handbags and the like.

The trunk is the second most capacious in the class, losing out to the Toyota Camry by less than half a cubic foot. Despite the use of gas-pressure struts (which the hood has, too, an upscale touch not all of the competition offer) and articulated linkage on the trunk lid, the Sonata's stubby back end constrains the opening; in other words, it holds a lot, just not big lots.

Korea's car makers have been unabashedly frank about their lack of sophistication in engine technology and metallurgy. They've acknowledged they have some distance to make up to compete in both regards with the best of Japan and, of late, the U.S. and Europe. This latest Hyundai Sonata marks a major step forward in the engine department and more than a couple steps forward in weight reduction.

Both of the 2007 Sonata's engines incorporate some of the latest developments in variable timing of intake valves, achieving the dual benefits of lower emissions and higher fuel efficiency. Both engines are rated LEVII ULEV (Ultra Low Emissions Vehicle) by the Environmental Protection Agency. Additionally, the V6 uses a variable-length intake manifold to fatten the torque curve and make more zip available over a broader range of engine speeds.

Fuel economy for the four-cylinder GLS with manual transmission, as estimated by the EPA, is 24 miles per gallon in the city and 34 mpg on the highway. The V6-powered SE and Limited are rated 20/30 mpg.

Acceleration is brisk in the four-cylinder and brings a grin to the face in the V6. Hyundai officials say the V6 will turn 0-60 miles per hour times of about 7.5 seconds, with a top speed of 130 mph. Shifts are executed easily with the five-speed manual, and chirping the front tires is even easier. The Shiftronic automatic transmission moves between gears smoothly, kicking down for passing with minimal hesitation. The automatic offered responsive performance while tackling the hills of San Francisco. In manual mode, the Shiftronic will upshift automatically when the engine bumps up against redline, and it declines to downshift at all, leaving that to the driver's preferences.

Steering is light and direct, with good on-center feel and directional stability. Brakes are mostly linear, and equipped with Electronic Brake-force Distribution, which improves stability and reduces stopping distances by balancing brake force between the front and rear tires; while ABS allows the driver to maintain steering control under hard braking. Yet we noticed little of the interference we've found with some more complex EBD-equipped systems, and then only in the final stages of a stop. The 17-inch wheel/tire combination makes its presence known on rough pavement, where the shorter sidewalls transmit more of the road's imperfections into the cabin. Wind and road noise is decently muted.

The suspension layout looks good on paper, with double wishbones in front, multiple control links in back, and twin-tube gas-pressure shocks and stabilizer bars all 'round. The V6 boasts a larger front bar to handle the larger engine's extra weight. But how it all works together still needs, well, work. Against the competition, which has been refining its suspension technology for much longer than Hyundai, the Sonata feels less polished, less of a whole. Not that there's anything wrong or necessarily lacking in the ride and handling. It's just that some of the transitions, in direction and between types and qualities of pavement, aren't as smooth as the look and feel of the Sonata promises. The front end tucks in nicely as steering is cranked in, but the car doesn't track as surely as expected. There's also the impression of poorly managed unsprung mass when the rear suspension crosses rough or broken pavement, which suggests the hard parts are a generation or two behind in the alloys used and how they're formed. Still, interstate-intensive travel, even at socially irresponsible speeds, is smooth and unruffled, which is no small achievement.

The 2007 Hyundai Sonata comes in three trim levels, GLS, SE, and Limited. The base engine is a 162-hp four-cylinder. The uplevel engine is a 234-hp V6. The four-cylinder is available with either a five-speed manual or a four-speed Shiftronic automatic. The V6 comes with the five-speed Shiftronic automatic introduced for 2006. Gone is last year's base-level Sonata GL.

The GLS ($17,195) comes with the four-cylinder engine and manual transmission or four-speed automatic ($18,295). Air conditioning; cruise control; power outside mirrors; power windows; central locking with keyless remote; AM/FM/CD/MP3 stereo with six speakers; a leather-wrapped, tilt steering wheel; and 16-inch wheels come standard. XM Satellite Radio will be standard later in the model year. Option packages for the GLS add 17-inch tires with five-spoke aluminum wheels, fog lamps, and luxury features.

The SE ($20,995) comes with the 3.3-liter V6 (with dual, chrome-tipped exhausts), five-speed Shiftronic automatic transmission, larger disc brakes, 17-inch alloy wheels fitted with lower-profile tires, solar-control glass, fog lights, chrome window belt moldings, driver's-seat lumbar support, steering wheel-mounted audio controls and a trip computer. Options include a power/tilt sunroof ($900), eight-way power driver's seat with electrochromic auto-dimming rearview mirror, HomeLink and compass ($550); or all of the above plus CD changer, MP3 player, subwoofer and amplifier ($1,950).

The Limited ($22,995) is a fully equipped luxury model featuring leather seating surfaces, eight-way power driver's seat, heated front seats, automatic climate control with automatic Air Quality System (AQS), electrochromic auto-dimming rear view mirror with HomeLink and compass, telescoping steering wheel, and a sliding center armrest. A new chrome center-bar grille and chrome-accented exterior door handles identify Limited from the outside. The only option is an Ultimate Package ($1750) consisting of a power/tilt sunroof and an Infinity AM/FM/MP3/6-CD changer with six speakers, subwoofer and component amplifier.

Safety features on all Sonatas include the mandatory dual-stage front-seat airbags; front-seat side-impact airbags for torso protection; and full-coverage side curtain airbags designed to provide head protection. Antilock brakes (ABS) with electronic brake-force distribution (EBD) and electronic stability control (ESC) with traction control come standard.
