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 Aston Martin DB11 doesn’t offer pretensioners for the rear seat belts.
The LC Series has a standard Pre-Collision System, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The DB11 doesn't offer collision warning or crash mitigation brakes.
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 DB11 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 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 DB11 doesn’t offer a lane departure warning system.
To help make backing safer, the LC Series’ 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 DB11 doesn’t offer a cross-path warning system.
The LC Series’ 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 DB11 doesn’t offer a driver alert monitor.
The LC Series has standard Safety Connect®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The DB11 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the LC Series and the DB11 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available rear parking sensors.
The LC Series comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The DB11’s 3-year basic warranty expires 1 year sooner.
Lexus’ powertrain warranty covers the LC Series 3 years longer than Aston Martin covers the DB11. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the DB11 ends after only 3 years.
There are almost 7 times as many Lexus dealers as there are Aston Martin dealers, which makes it much easier should you ever need service under the LC Series’ warranty.
On the EPA test cycle the LC 500h Auto gets better fuel mileage than the DB11 V8 (26 city/34 hwy vs. 18 city/24 hwy).
On the EPA test cycle the LC 500 Convertible gets better fuel mileage than the DB11 AMR V12 (15 city/25 hwy vs. 15 city/22 hwy).
Regenerative brakes improve the LC Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The DB11 doesn’t offer a regenerative braking system.
The LC Series Hybrid’s standard fuel tank has 1.1 gallons more fuel capacity than the DB11 (22.2 vs. 21.1 gallons).
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 Aston Martin DB11 (3). This means the LC Series produces up to 24.5 pounds less smog-producing pollutants than the DB11 every 15,000 miles.
A 10-speed automatic is standard on the Lexus LC Series, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the DB11.
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 DB11 doesn’t offer a CVT.
The LC Series stops shorter than the DB11:
70 to 0 MPH
Car and Driver
For better ride, handling and brake cooling the LC Series offers optional 21-inch wheels. The DB11’s largest wheels are only 20-inches.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the LC Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The DB11 doesn’t offer run-flat tires.
For a smoother ride and more stable handling, the LC Series’ wheelbase is 2.6 inches longer than on the DB11 (113 inches vs. 110.4 inches).
For better maneuverability, the LC Series Active Rear Steering’s turning circle is 3.7 feet tighter than the DB11’s (34.8 feet vs. 38.5 feet). The LC Series’ turning circle is 3.1 feet tighter than the DB11’s (35.4 feet vs. 38.5 feet).
The LC Series Convertible uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The DB11 doesn’t offer active noise cancellation.
The LC Series has 9.9 cubic feet more passenger volume than the DB11 (85.9 vs. 76).
The LC Series has 2.2 inches more front shoulder room, 4.2 inches more rear legroom and .3 inches more rear shoulder room than the DB11.
With its coupe body style, valet key and remote trunk release lockout, the LC Series offers cargo security. The DB11’s non-lockable remote release defeats cargo security.
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the LC Series. The DB11 doesn’t offer locking storage for small valuables.
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 DB11 doesn’t offer a remote starting 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 DB11 doesn’t offer a heads-up display.
The LC Series’ 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. Aston Martin does not offer a locking feature on the DB11’s standard power windows.
The LC Series’ 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 DB11’s cruise control switches are unlit, making them difficult to find at night and operate safely.
While driving with high beams on, sensitive light sensors standard on the LC Series detect other vehicles which could be blinded and automatically switch to low beams. The DB11 doesn’t offer automatic dimming high beams.
The LC Series’ sun-visors swivel front-to-side to block glare from the side windows. The DB11’s visors are fixed into the windshield header.
The LC Series’ standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The DB11 has an automatic rear view mirror, but its side mirrors don’t dim.
To keep a safe, consistent following distance, the LC Series has a standard Dynamic Radar Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The DB11 doesn’t offer an adaptive cruise control.
Motor Trend performed a comparison test in its November 2017 issue and they ranked the Lexus LC 500 four places higher than the Aston Martin DB11.
The LC Series was chosen as one of Automobile Magazine’s “All Stars” in 2018. The DB11 has never been an “All Star.”
