For enhanced safety, the front and rear seat shoulder belts of the Acura TLX 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-V doesn’t offer pretensioners for its rear seat belts.

The TLX’s 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-V doesn’t offer a driver alert monitor.

Both the TLX and the CT5-V 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, rearview cameras, available all wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Acura TLX is safer than the Cadillac CT5-V:

	TLX	CT5-V
	Driver
STARS	5 Stars	5 Stars
HIC	143	155
Neck Injury Risk	20%	24%
Neck Stress	175 lbs.	217 lbs.
Leg Forces (l/r)	258/267 lbs.	408/341 lbs.

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 Acura TLX is safer than the Cadillac CT5-V:

	TLX	CT5-V
	Front Seat
STARS	5 Stars	5 Stars
HIC	128	129
Chest Movement	.8 inches	.9 inches
Abdominal Force	188 lbs.	209 lbs.

Spine Acceleration	33 G’s	35 G’s
Hip Force	484 lbs.	558 lbs.

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

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the TLX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 112 vehicles tested by the IIHS. The CT5-V has not been tested, yet.

Warranty

Acura pays for scheduled maintenance on the TLX for 2 years and 24,000 miles. Acura will pay for oil changes, lubrication and any other required maintenance. Cadillac only pays for the first scheduled maintenance visit on the CT5-V.

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the TLX have an overhead cam design, rather than the old pushrod design of the 6.2 supercharged V8 in the CT5-V.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Acura vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Acura 9 places higher in reliability than Cadillac.

Fuel Economy and Range

On the EPA test cycle the TLX gets better mileage than the CT5-V:

			MPG
TLX
FWD	Auto	2.0 turbo 4-cyl.	22 city/31 hwy
		A-Spec 2.0 turbo 4-cyl.	22 city/30 hwy
AWD	Auto	2.0 turbo 4-cyl.	21 city/29 hwy
CT5-V
RWD	Manual	6.2 supercharged V8	13 city/21 hwy
	Auto	6.2 supercharged V8	13 city/21 hwy
		3.0 turbo V6	18 city/27 hwy
AWD	Auto	3.0 turbo V6	18 city/26 hwy

Regardless of its engine, the TLX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CT5-V Blackwing doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Acura TLX uses regular unleaded gasoline (premium recommended for maximum performance). The CT5-V requires premium, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Acura TLX higher (5 to 7 out of 10) than the Cadillac CT5-V (3 to 5). This means the TLX produces up to 24.5 pounds less smog-producing pollutants than the CT5-V every 15,000 miles.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the TLX is 1 inch wider in the front and 1.5 inches wider in the rear than the average track on the CT5-V.

The TLX Type S handles at .97 G’s, while the CT5-V pulls only .96 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the TLX’s turning circle is 2.5 feet tighter than the CT5-V Blackwing’s (40.1 feet vs. 42.6 feet).

Chassis

The Acura TLX may be more efficient, handle and accelerate better because it weighs up to about 250 pounds less than the Cadillac CT5-V.

The TLX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The CT5-V doesn’t offer active noise cancellation.

As tested by Car and Driver while cruising at 70 MPH, the interior of the TLX Type S is quieter than the CT5-V Blackwing (71 vs. 74 dB).

Passenger Space

The TLX has .1 inches more front legroom, 2.1 inches more front hip room, 1.5 inches more front shoulder room and .9 inches more rear hip room than the CT5-V.

Cargo Capacity

The TLX has a much larger trunk than the CT5-V (13.5 vs. 11.9 cubic feet).

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

Ergonomics

If the windows are left open on the TLX 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. The driver of the CT5-V can only close the windows from inside the vehicle, with the ignition on.

The TLX has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. A locking fuel door is only offered on the CT5-V Blackwing.

The TLX has standard heated front seats. Heated front seats cost extra on the CT5-V. The TLX Advance also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the CT5-V.
