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 Infiniti Q60 doesn’t offer pretensioners for the rear seat belts.

The LC Series 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 Q60 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.

Both the LC Series and the Q60 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, daytime running lights, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Warranty

There are over 12 percent more Lexus dealers than there are Infiniti dealers, which makes it easier should you ever need service under the LC Series’ warranty.

Reliability

The battery on the LC Series is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the LC Series’ battery 20 to 30 degrees cooler, its life is increased by years. The Q60’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Lexus 8th in initial quality, above the industry average. With 8 more problems per 100 vehicles, Infiniti is ranked 14th.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 21 more problems per 100 vehicles, Infiniti is ranked fourth.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Infiniti vehicles. Consumer Reports ranks Lexus first in reliability. Infiniti is ranked 6th.

Engine

The LC 500h’s standard 3.5 DOHC V6 hybrid produces 54 more horsepower (354 vs. 300) than the Q60 3.0t’s standard 3.0 turbo V6. The LC 500’s standard 5.0 DOHC V8 produces 71 more horsepower (471 vs. 400) and 48 lbs.-ft. more torque (398 vs. 350) than the Q60 Red Sport 400’s standard 3.0 turbo V6.

As tested in Motor Trend the LC 500h is faster than the Q60 3.0t:

Fuel Economy and Range

On the EPA test cycle the LC 500h gets better fuel mileage than the Q60 Red Sport 400 RWD (26 city/35 hwy vs. 20 city/27 hwy).

Regenerative brakes improve the LC Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Q60 doesn’t offer a regenerative braking system.

The LC Series’ standard fuel tank has 1.7 gallons more fuel capacity than the Q60 (21.7 vs. 20 gallons), for longer range between fill-ups. The LC Series Hybrid’s standard fuel tank has 2.2 gallons more fuel capacity than the Q60 (22.2 vs. 20 gallons).

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 Infiniti Q60 (3). This means the LC Series produces up to 24.5 pounds less smog-producing pollutants than the Q60 every 15,000 miles.

Transmission

A 10-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 Q60.

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 Q60 doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the LC Series’ brake rotors are larger than those on the Q60:

Tires and Wheels

For better traction and acceleration, the LC Series has larger rear tires than the Q60 (275/40R20 vs. 255/40R19).

For better ride, handling and brake cooling the LC Series has standard 20-inch wheels. Smaller 19-inch wheels are standard on the Q60. The LC Series’ optional 21-inch wheels are larger than the 20-inch wheels on the Q60 Red Sport 400.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the LC Series is 2.9 inches wider in the front and 2.2 inches wider in the rear than the average track on the Q60.

The LC 500 handles at .93 G’s, while the Q60 Red Sport 400 AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

The LC 500 executes Motor Trend’s “Figure Eight” maneuver quicker than the Q60 Red Sport 400 (24.6 seconds @ .79 average G’s vs. 25.5 seconds @ .76 average G’s).

For better maneuverability, the LC Series’ turning circle is 1.3 feet tighter than the Q60’s (35.4 feet vs. 36.7 feet). The LC Series’ turning circle is 2.7 feet tighter than the Q60 AWD’s (35.4 feet vs. 38.1 feet).

Passenger Space

The LC Series has .2 inches more front hip room, 1.9 inches more front shoulder room and .1 inches more rear legroom than the Q60.

Servicing Ease

The LC Series has a maintenance free battery for long life without checking the battery’s water level. The Q60 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

Ergonomics

The LC Series’ standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Q60 doesn’t offer an easy entry system.

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 Q60 doesn’t offer a heads-up display.

The power windows standard on both the LC Series and the Q60 have locks to prevent small children from operating them. When the lock on the LC Series is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Q60 prevents the driver from operating the other windows just as it does the other passengers.

Smart Access standard on the LC Series allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Infiniti Q60’s Infiniti Intelligent Key doesn’t unlock the trunk.

The LC Series’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Q60’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Optional air-conditioned seats in the LC Series keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Q60 doesn’t offer air-conditioned seats.

The LC Series has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The Q60 doesn’t offer a rear seat center armrest.

Recommendations

The LC Series was chosen as one of Automobile Magazine’s “All Stars” in 2018. The Q60 has never been an “All Star.”
