Compare the2024 Lexus ESVS 2024 Cadillac CT5

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 Cadillac CT5 doesn’t offer pretensioners for its rear seat belts.

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 CT5 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 CT5 have rear cross-traffic warning, but the ES offers optional Rear Cross-Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The CT5’s Rear Cross Traffic Alert doesn’t automatically brake.

The ES’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CT5 doesn’t offer a driver alert monitor.

Both the ES and the CT5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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 and available around view monitors.

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 Cadillac CT5:

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 98 vehicles tested by the IIHS. The CT5 has not been tested, yet.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Lexus ES Hybrid’s reliability 28 points higher than the CT5 and the Lexus ES is rated 30 points higher than the CT5.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Lexus above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, Cadillac is rated lower.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Lexus vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Lexus first in overall reliability. Cadillac is ranked 16th.

As tested in Consumer Reports the ES 350 3.5 DOHC V6 is faster than the Cadillac CT5 turbo 4 cyl.:

On the EPA test cycle the ES gets better mileage than the CT5:

The ES can travel with zero emissions on a full charge for 1.6 miles. The CT5 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 CT5 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lexus ES uses regular unleaded gasoline. The CT5 with the 3.0 turbo V6 engine requires premium, which can cost on average about 82.8 cents more per gallon.

The ES has a standard locking fuel door with a power remote release convenient to the driver. The fuel filler door is not lockable on the CT5. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

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 CT5 doesn’t offer a CVT.

The ES has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the CT5; it requires you to depend on its optional run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

For better maneuverability, the ES’ turning circle is 1 foot tighter than the CT5’s (38 feet vs. 39 feet). The ES’ turning circle is 2.7 feet tighter than the CT5 AWD’s (38 feet vs. 40.7 feet).

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 CT5 doesn’t offer active noise cancellation.

The ES has 1.3 inches more front hip room, 1.2 inches more rear headroom, 1.3 inches more rear legroom and .6 inches more rear hip room than the CT5.

The front step up height for the ES is 1.8 inches lower than the CT5 (14.8” vs. 16.6”). The ES’ rear step up height is 2.7 inches lower than the CT5’s (15” vs. 17.7”).

The ES has a much larger trunk than the CT5 (13.9 vs. 11.9 cubic feet).

With its sedan body style, valet key and remote trunk release lockout, the ES offers cargo security. The CT5’s non-lockable folding seat defeats cargo security.

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 CT5 doesn’t offer a power trunk, so its trunk has to be closed manually.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Cadillac. J.D. Power ranks Lexus first in service department satisfaction. With a 17% lower rating, Cadillac is ranked second.

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 CT5 can only close the windows from inside the vehicle, with the ignition on.

The CT5 Premium Luxury/Sport’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The ES’ optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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 CT5 doesn’t offer a rear or rear side window sunshades.

The ES will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the ES will retain 52.03% to 57.94% of its original price after five years, while the CT5 only retains 49.33% to 50.43%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Lexus ES will be $1292 to $4838 less than for the Cadillac CT5.

Consumer Reports® recommends both the Lexus ES and the Cadillac CT5, based on reliability, safety and performance.

J.D. Power and Associates rated the ES third among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The CT5 isn’t in the top three.

The Lexus ES outsold the Cadillac CT5 by over two to one during 2023.
