Safety

For enhanced safety, the front and rear seat shoulder belts of the Lexus LC Series 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 the rear seat belts.

The LC Series’ 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. The 911 doesn’t offer a lane departure warning system.

To help make backing safer, the LC Series’ 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 911 doesn’t offer a cross-path warning system.

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

The Lexus LC Series weighs 598 to 1319 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

Lexus’ powertrain warranty covers the LC Series 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 26 percent more Lexus dealers than there are Porsche dealers, which makes it easier should you ever need service under the LC Series’ warranty.

Reliability

J.D. Power and Associates’ 2016 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 first in reliability, above the industry average. With 2 more problems per 100 vehicles, Porsche is ranked second.

From surveys of all its subscribers, Consumer Reports’ April 2017 Auto Issue reports that Lexus vehicles are more reliable than Porsche vehicles. Consumer Reports ranks Lexus first in reliability. Porsche is ranked 16th.

Fuel Economy and Range

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

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus LC Series higher (5 to 7 out of 10) than the Porsche 911 (1). This means the LC Series produces up to 47 pounds less smog-producing pollutants than the 911 every 15,000 miles.

Transmission

The Lexus LC Series comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the 911.

A ten-speed automatic is standard on the Lexus LC Series, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the 911.

Brakes and Stopping

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

Tires and Wheels

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

For better ride, handling and brake cooling the LC Series has standard 20-inch wheels. Smaller 19-inch wheels are standard on the 911. The LC Series’ optional 21-inch wheels are larger than the 20-inch front wheels and 21-inch rear wheels on the 911 GT2 RS Coupe.

Suspension and Handling

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

For better handling and stability, the track (width between the wheels) on the LC Series is 3.4 inches wider in the front and 3.2 inches wider in the rear than the average track on the 911.

The LC Series’ front to rear weight distribution is more even (52% to 48%) than the 911’s (39.3% to 60.7%). This gives the LC Series more stable handling and braking.

Passenger Space

Because it has more passenger and cargo room, the LC Series is rated a Subcompact car by the EPA, while the 911 Coupe is rated a Minicompact.

The LC Series has 15.9 cubic feet more passenger volume than the 911 Coupe (85.9 vs. 70).

The LC Series has 5.7 inches more front shoulder room, 1.2 inches more rear headroom, 7.5 inches more rear legroom and .6 inches more rear shoulder room than the 911 Coupe.

Cargo Capacity

The LC Series has a larger trunk than the 911 Coupe with its rear seat up (5.4 vs. 5.1 cubic feet).

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

Ergonomics

The LC Series 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 Series’ 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 Series offers an optional heads-up display that projects speed and other key instrumentation 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 Series has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The 911 doesn’t offer a rear seat center armrest.
