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

There are over 23 percent more Lexus dealers than there are Porsche dealers, which makes it easier should you ever need service under the LS’ warranty.

On the EPA test cycle the LS gets better mileage than the Panamera running its gasoline engine:

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

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

The LS 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 Panamera doesn’t offer a CVT.

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

The LS F-Sport offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Panamera doesn’t offer an active sway bar system.

For a smoother ride and more stable handling, the LS’ wheelbase is 6.9 inches longer than on the Panamera (123 inches vs. 116.1 inches).

For better maneuverability, the LS’ turning circle is 2.2 feet tighter than the Panamera’s (36.8 feet vs. 39 feet).

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

With its sedan body style, valet key and remote trunk release lockout, the LS offers cargo security. The Panamera’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat 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 3% lower rating, Porsche is ranked second.

The LS 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 Panamera doesn’t offer a remote starting system.

If the windows are left open on the LS 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 Panamera can only operate the windows from inside the vehicle, with the ignition on.

The LS’ power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Panamera’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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

The LS offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Panamera doesn’t offer a house-current electrical outlet.
