For enhanced safety, the front and rear seat shoulder belts of the Lexus RC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Porsche 911 doesn’t offer pretensioners for the rear seat belts.

The RC’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 911 doesn’t offer pre-crash pretensioners.

The RC’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The 911 doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the RC’s 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.

The RC’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 RC and the 911 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive and rear parking sensors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the RC the rating of “Top Pick” for 2017, a rating granted to only 180 vehicles tested by the IIHS. The 911 has not been tested, yet.

Lexus’ powertrain warranty covers the RC 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 RC’s warranty.

The RC 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 911; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For a smoother ride and more stable handling, the RC’s wheelbase is 11 inches longer than on the 911 (107.5 inches vs. 96.5 inches).

For better handling and stability, the average track (width between the wheels) on the RC is 1.2 inches wider in the rear than the average track on the 911.

The RC’s front to rear weight distribution is more even (54% to 46%) than the 911’s (36.4% to 63.6%). This gives the RC more stable handling and braking.

For better maneuverability, the RC’s turning circle is 1.6 feet tighter than the 911 w/Rear Wheel Steering’s (34.2 feet vs. 35.8 feet). The RC AWD’s turning circle is 2 feet tighter than the 911’s (34.8 feet vs. 36.8 feet).

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

The RC has 10.8 cubic feet more passenger volume than the 911 (83.8 vs. 73).

The RC has 1.1 inches more front headroom, 3.2 inches more front legroom, 2.1 inches more front shoulder room, 2.3 inches more rear headroom, .1 inches more rear legroom and 2.9 inches more rear shoulder room than the 911.

The RC has a much larger trunk than the 911 Coupe with its rear seat up (10.4 vs. 4.6 cubic feet).

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

The RC 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 RC’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 RC 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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RC offers available headlight washers to keep headlight output high. The 911 doesn’t offer headlight washers.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the RC has standard extendable sun visors. The 911 doesn’t offer extendable visors.
