The Sonata Limited/Sport 2.0T offers an optional collision warning system, which detects an impending crash through forward mounted sensors and flashes a bright light and sounds a loud, distinctive tone to warn the driver to brake or maneuver immediately to avoid a collision. The Impala Limited doesn't offer a collision warning system.

The Sonata (except SE)’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Impala Limited doesn’t offer a lane departure warning system.

The Sonata Limited/Sport 2.0T offers optional Rear Parking Assistance System to help warn drivers about vehicles, pedestrians or other obstacles behind their vehicle. The Sonata also offers an optional backup monitor to help drivers see any and all obstacles behind their vehicle. The Impala Limited doesn’t offer any parking assist system.

The Sonata (except SE)’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Impala Limited doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the Sonata’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Impala Limited doesn’t offer a cross-path warning system.

Both the Sonata and the Impala Limited have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, height-adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

The Insurance Institute for Highway Safety ( IIHS) performs roof strength tests. In that test the Sonata earned the top rating of “Good” because its roof supported over four times the Sonata’s weight before being crushed five inches. The Impala Limited was rated lower at “Acceptable.”

The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the Sonata is safer then the Impala Limited:

For its top level performance in the IIHS moderate overlap frontal impact, side impact, rear impact, roof-crush crash tests, an “Acceptable” rating in the newer small overlap frontal crash test, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Sonata its highest rating: “Top Pick Plus” for 2014, a rating granted to only 52 vehicles tested by the IIHS. The Impala Limited is not even a standard “Top Pick.”

The Hyundai Sonata may be more efficient, handle and accelerate better because it weighs about 50 to 300 pounds less than the Chevrolet Impala Limited.

The Sonata is 9.3 inches shorter than the Impala Limited, making the Sonata easier to handle, maneuver and park in tight spaces.

The design of the Hyundai Sonata amounts to more than styling. The Sonata has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the Impala Limited (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Sonata get better fuel mileage.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Sonata offers cargo security. The Impala Limited’s non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Sonata. The Impala Limited doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the Sonata’s available trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Impala Limited doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

To help each driver find a more comfortable driving position, the Sonata has a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The Impala Limited doesn’t offer a telescoping steering wheel.

When different drivers share the Sonata Limited/Sport 2.0T, the optional memory seats and mirrors make it convenient. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Impala Limited doesn’t offer a memory system.

The Sonata Limited/Sport 2.0T’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Impala Limited doesn’t offer an easy entry system.

The Sonata’s standard driver’s power window opens or closes with one touch of the switch, making it more convenient at drive-up windows and toll booths. The Impala Limited’s power window switch has to be held the entire time to close it fully. The Sonata’s optional front power windows open fully with one touch of the switches, and its driver’s window also automatically closes.

Proximity entry with push-button start optional on the Sonata allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Chevrolet Impala Limited doesn’t offer an advanced key system.

The Sonata has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Impala Limited doesn’t offer a locking fuel door.

While driving with high beams on, sensitive light sensors available for the Sonata Limited/Sport 2.0T detect other vehicles which could be blinded and automatically switch to low beams. The Impala Limited doesn’t offer automatic dimming high beams.

The Sonata’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Heated mirrors cost extra on the Impala Limited and aren’t offered on the Impala Limited LS.

When the Sonata is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Impala Limited’s mirrors don’t automatically adjust for backing.

Both the Sonata and the Impala Limited offer available heated front seats. The Sonata also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Impala Limited.

The Sonata Limited/Sport 2.0T’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The Impala Limited doesn’t offer air conditioned front seats.

On extremely cold Winter days, the Sonata Limited’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Impala Limited doesn’t offer a heated steering wheel.

The Sonata’s optional automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The Impala Limited doesn’t offer automatic air conditioning.

For greater rear passenger comfort, the Sonata has standard rear a/c vents to keep rear occupants more comfortable. The Impala Limited doesn’t offer rear vents.

To keep a safe, consistent following distance, the Sonata Limited/Sport 2.0T offers an optional Smart Cruise Control with Full Stop, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Impala Limited doesn’t offer an adaptive cruise control.

Optional Blue Link for the Sonata allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The Impala Limited doesn’t offer factory integrated smartphone program access.

The Sonata Eco/Sport/Limited’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Impala Limited’s available navigation system doesn’t offer real-time traffic updates.

With optional voice command, the Sonata offers the driver hands free control of the radio, cell phone and the navigation computer by simply speaking. The Impala Limited doesn’t offer a voice control system.
