Compare the2023 Lexus LCVS 2023 Porsche 911

For enhanced safety, the front and rear seat shoulder belts of the Lexus LC 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 Porsche 911 doesn’t offer pretensioners for its rear seat belts.

The Lexus LC 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 911 doesn’t offer knee airbags.

The LC has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 911 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.

The LC’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 911.

The LC has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 911’s blind spot costs extra.

To help make backing out of a parking space safer, the LC’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 911 doesn’t offer a rear cross-path warning system.

The LC’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 911 doesn’t offer a driver alert monitor.

Both the LC and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available rear parking sensors.

The Lexus LC weighs 550 to 1414 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Lexus’ powertrain warranty covers the LC 2 years and 20,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

There are over 25 percent more Lexus dealers than there are Porsche dealers, which makes it easier should you ever need service under the LC’s warranty.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Lexus above average in initial quality. With 43 more problems per 100 vehicles, Porsche is rated below average.

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 Porsche 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, Porsche is rated lower.

On the EPA test cycle the LC Coupe gets better mileage than the 911 Coupe:

The LC can travel with zero emissions on a full charge for .6 miles. The 911 can’t move without running its internal combustion engine.

The LC can travel with zero emissions on a full charge for .6 miles. The 911 can’t move without running its internal combustion engine.

Regenerative brakes improve the LC Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The 911 doesn’t offer a regenerative braking system.

The LC’s standard fuel tank has 4.8 gallons more fuel capacity than the 911’s standard fuel tank (21.7 vs. 16.9 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus LC higher (5 to 7 out of 10) than the Porsche 911 (3 to 5). This means the LC produces up to 24.5 pounds less smog-producing pollutants than the 911 every 15,000 miles.

A 10-speed automatic is standard on the Lexus LC, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the 911.

The LC 500h 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 911 doesn’t offer a CVT.

For better stopping power the LC’s standard brake rotors are larger than those on the 911:

For better traction, the LC has larger front tires than the 911 (245/45R20 vs. 235/40R19).

For better ride, handling and brake cooling the LC has standard 20-inch wheels. Smaller 19-inch front wheels are standard on the 911. The LC’s optional 21-inch wheels are larger than the 20-inch front wheels and 21-inch rear wheels optional on the 911.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LC can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The 911 doesn’t offer run-flat tires.

For a smoother ride and more stable handling, the LC’s wheelbase is 16.5 inches longer than on the 911 (113 inches vs. 96.5 inches). The LC’s wheelbase is 16.3 inches longer than on the 911 GT3 (113 inches vs. 96.7 inches).

For better handling and stability, the track (width between the wheels) on the LC is 1.6 inches wider in the front and 2.8 inches wider in the rear than the average track on the 911.

The LC’s front to rear weight distribution is more even (52% to 48%) than the 911’s (39.5% to 60.5%). This gives the LC more stable handling and braking.

The LC Convertible uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 911 doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the LC 500h is quieter than the 911 Turbo S Coupe:

The LC has 12.9 cubic feet more passenger volume than the 911 (85.9 vs. 73).

The LC has 3.9 inches more front shoulder room, 5.3 inches more rear legroom and 1 inch more rear shoulder room than the 911 Coupe.

The LC has a larger trunk than the 911 Coupe with its rear seat up (5.4 vs. 4.6 cubic feet).

With its coupe body style, valet key and remote trunk release lockout, the LC offers cargo security. The 911’s non-lockable folding seat defeats cargo security.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Porsche. J.D. Power ranks Lexus first in service department satisfaction. With a 18% lower rating, Porsche is ranked third.

The LC has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 911 doesn’t offer a remote starting system.

The LC’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the 911.

The LC offers an optional heads-up display that projects speed, tachometer 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 911 doesn’t offer a heads-up display.

The LC’s standard power windows have a locking feature to keep children from operating them, but the driver can still raise and lower both of them with the lock engaged. Porsche does not offer a locking feature on the 911’s standard power windows.

If the front windows are left open on the LC the driver can close them 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 911 can only operate the windows from inside the vehicle, with the ignition on.
