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 Vantage 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 Vantage 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 Vantage 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 Vantage 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 Vantage 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 Vantage 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 Vantage have standard driver and passenger frontal airbags, front side-impact airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and available rear parking sensors.
The Lexus LC Series weighs 614 to 1023 pounds more than the Aston Martin Vantage. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
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 Vantage’s 3-year basic warranty expires 1 year sooner.
Lexus’ powertrain warranty covers the LC Series 3 years longer than Aston Martin covers the Vantage. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Vantage 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 Vantage Auto (26 city/34 hwy vs. 18 city/24 hwy).
Regenerative brakes improve the LC Series Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The Vantage doesn’t offer a regenerative braking system.
The LC Series’ standard fuel tank has 2.4 gallons more fuel capacity than the Vantage’s standard fuel tank (21.7 vs. 19.3 gallons), for longer range between fill-ups. The LC Series Hybrid’s standard fuel tank has 1.6 gallons more fuel capacity than the Vantage AMR’s standard fuel tank (22.2 vs. 20.6 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 Vantage (3). This means the LC Series produces up to 24.5 pounds less smog-producing pollutants than the Vantage 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 Vantage.
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 Vantage doesn’t offer a CVT.
For better ride, handling and brake cooling the LC Series offers optional 21-inch wheels. The Vantage’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 Vantage doesn’t offer run-flat tires.
For a smoother ride and more stable handling, the LC Series’ wheelbase is 6.5 inches longer than on the Vantage (113 inches vs. 106.5 inches).
For better maneuverability, the LC Series Active Rear Steering’s turning circle is 3.9 feet tighter than the Vantage’s (34.8 feet vs. 38.7 feet). The LC Series’ turning circle is 3.3 feet tighter than the Vantage’s (35.4 feet vs. 38.7 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 Vantage doesn’t offer active noise cancellation.
As tested by Car and Driver, the interior of the LC 500h is quieter than the Vantage Coupe:
70 MPH Cruising
The LC Series has standard seating for 4 passengers; the Vantage can only carry 2.
The LC Series has 38.9 cubic feet more passenger volume than the Vantage (85.9 vs. 47).
The LC Series has 1 inch more front headroom and 3.5 inches more front shoulder room than the Vantage Coupe.
With its coupe body style, valet key and remote trunk release lockout, the LC Series offers cargo security. The Vantage’s hatchback body style and non-lockable remote release defeat 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 Vantage 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 Vantage 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 Vantage 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 Vantage’s standard power windows.
The LC Series’ front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Vantage’s power windows’ switches have to be held the entire time to close them fully.
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 Vantage doesn’t offer automatic dimming high beams.
To help drivers avoid possible obstacles, the LC Series has standard cornering lights to illuminate around corners when the turn signals are activated. The Vantage doesn’t offer cornering lights.
The LC Series’ sun-visors swivel front-to-side to block glare from the side windows. The Vantage’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 Vantage has an automatic rear view mirror, but its side mirrors don’t dim.
On extremely cold winter days, the LC Series’ optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Vantage doesn’t offer a heated steering wheel.
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 Vantage doesn’t offer an adaptive cruise control.
The Lexus LC Series comes in coupe and convertible bodystyles; the Aston Martin Vantage isn’t available as a convertible.
The LC Series was chosen as one of Automobile Magazine’s “All Stars” in 2018. The Vantage has never been an “All Star.”
