For enhanced safety, the front and rear seat shoulder belts of the Lexus ES have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia K5 doesn’t offer pretensioners for its rear seat belts.

The Lexus ES has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The K5 doesn’t offer a front passenger side knee airbag.

The ES has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The K5 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Both the ES and the K5 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus ES is safer than the Kia K5:

	ES	K5
	Driver
STARS	5 Stars	5 Stars
HIC	120	295
	Passenger
STARS	4 Stars	4 Stars
HIC	319	373
Neck Injury Risk	33%	50%

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Lexus ES is safer than the Kia K5:

	ES	K5
	Front Seat

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the ES the rating of “Top Safety Pick” for 2023, a rating granted to only 54 vehicles tested by the IIHS. The K5 has not been fully tested, yet.

Warranty

The ES’ corrosion warranty is 1 year and unlimited miles longer than the K5’s (6/unlimited vs. 5/100,000).

Reliability

J.D. Power and Associates rated the ES third among midsize premium cars in their 2023 Initial Quality Study. The K5 isn’t in the top three in its category.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lexus vehicles are more reliable than Kia vehicles. Consumer Reports ranks Lexus second in overall reliability. Kia is ranked 9th.

Engine

The ES has more powerful engines than the K5:

	Horsepower
ES 250 AWD 2.5 DOHC 4-cylinder	203 HP
ES 300h 2.5 DOHC 4-cylinder hybrid	215 HP
ES 350 3.5 DOHC V6	302 HP
K5 1.6T 1.6 turbo 4-cylinder	180 HP
K5 GT 2.5T 2.5 turbo 4-cylinder	290 HP

As tested in Consumer Reports the ES 350 3.5 DOHC V6 is faster than the K5 1.6T 1.6 turbo 4-cylinder:

	ES	K5
Zero to 30 MPH	3 sec	3.1 sec
Zero to 60 MPH	6.9 sec	7.7 sec
45 to 65 MPH Passing	4.2 sec	4.8 sec
Quarter Mile	15.4 sec	16 sec
Speed in 1/4 Mile	97 MPH	92 MPH

Fuel Economy and Range

On the EPA test cycle the ES gets better mileage than the K5:

			MPG
ES
	FWD	2.5 4-cyl. Hybrid	43 city/44 hwy
	AWD	2.5 DOHC 4-cyl.	25 city/34 hwy
K5
	FWD	1.6 turbo 4-cyl.	27 city/37 hwy
		2.5 turbo 4-cyl.	24 city/32 hwy
	AWD	1.6 turbo 4-cyl.	25 city/33 hwy

The ES can travel with zero emissions on a full charge for 1.6 miles. The K5 can’t move without running its internal combustion engine.

Regenerative brakes improve the ES Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The K5 doesn’t offer a regenerative braking system.

Transmission

The ES 300h has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The K5 doesn’t offer a CVT.

Brakes and Stopping

The ES stops shorter than the K5:

	ES	K5
60 to 0 MPH (Wet)	139 feet	140 feet	Consumer Reports

Tires and Wheels

For better traction, the ES has larger standard tires than the K5 (215/55R17 vs. 205/65R16).

The ES’ standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the K5 LXS’ standard 65 series tires.

For better ride, handling and brake cooling the ES has standard 17-inch wheels. Smaller 16-inch wheels are standard on the K5 LXS.

Suspension and Handling

The ES offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The K5’s suspension doesn’t offer adjustable shock absorbers.

Chassis

The ES F Sport uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The K5 doesn’t offer active noise cancellation.

Cargo Capacity

A low lift-over trunk design makes loading and unloading the ES easier. The ES’ trunk lift-over height is 27.4 inches, while the K5’s liftover is 28.6 inches.

With its sedan body style, valet key and remote trunk release lockout, the ES offers cargo security. The K5’s non-lockable remote release defeats cargo security.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the ES. The K5 doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier, especially for short adults, the ES offers an optional power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The K5 doesn’t offer a power trunk, so its trunk has to be closed manually.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Kia. J.D. Power ranks Lexus first in service department satisfaction. With a 63% lower rating, Kia is ranked 26th.

Ergonomics

The ES offers an optional heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The K5 doesn’t offer a heads-up display.

The ES’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The K5’s standard passenger windows don’t open or close automatically.

If the windows are left open on the ES the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the K5 can only operate the windows from inside the vehicle, with the ignition on.

The ES’ optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The K5’s manually variable intermittent wipers have to be constantly adjusted.

To help drivers see further while navigating curves, the ES offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The K5 doesn’t offer cornering lights.

A power rear sunshade is optional in the ES and manual rear side window sunshades are standard in the ES Ultra Luxury to help block heat and glare for the rear passengers. The K5 doesn’t offer a rear or rear side window sunshades.

When the ES with available tilt-down mirrors 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 K5’s mirrors don’t automatically adjust for backing.

The ES’ standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The K5 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the ES and the K5 offer rear vents. For greater rear passenger comfort, the ES has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The K5 doesn’t offer rear air conditioning vents, only heat vents.
