The Dawn’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Vanquish doesn’t offer pre-crash pretensioners.
The Dawn has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Vanquish doesn’t offer a whiplash protection system.
The Dawn has standard PostCrash, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Vanquish 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 Rolls-Royce Dawn has Daytime Running Lights to help keep it more visible under all conditions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The Vanquish doesn’t offer Daytime Running Lights.
An active infrared night vision system optional on the Dawn helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The Vanquish doesn’t offer a night vision system.
The Dawn’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Vanquish doesn’t offer a lane departure warning system.
The Dawn has a standard Top-View Camera to allow the driver to see objects all around the vehicle on a screen. The Vanquish only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Dawn’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 Vanquish doesn’t offer a driver alert monitor.
The Dawn has standard Rolls Royce Assist, 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 Vanquish 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 Dawn and the Vanquish 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 and front and rear parking sensors.
The Rolls-Royce Dawn weighs 1127 to 1369 pounds more than the Aston Martin Vanquish. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
The Dawn comes with a full 4-year/unlimited-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Vanquish’s 3-year/unlimited-mile basic warranty expires 1 year sooner.
Rolls-Royce pays for scheduled maintenance on the Dawn for 4 years and unlimited miles. Rolls-Royce will pay for oil changes, lubrication and any other required maintenance. Aston Martin doesn’t pay scheduled maintenance for the Vanquish.
To reliably power the ignition and other systems and to recharge the battery, the Dawn has a standard 220-amp alternator. The Vanquish’s 200-amp alternator isn’t as powerful.
The Dawn’s standard 6.6 turbo V12 produces 140 lbs.-ft. more torque (605 vs. 465) than the Vanquish’s 5.9 DOHC V12. The Dawn Black Label’s standard 6.6 turbo V12 produces 13 more horsepower (593 vs. 580) and 155 lbs.-ft. more torque (620 vs. 465) than the Vanquish’s 5.9 DOHC V12.
The Dawn has 1.4 gallons more fuel capacity than the Vanquish (21.9 vs. 20.5 gallons), for longer range between fill-ups.
For better ride, handling and brake cooling the Dawn offers optional 21-inch wheels. The Vanquish’s largest wheels are only 20-inches.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Dawn can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Vanquish doesn’t offer run-flat tires.
The Dawn has 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 Vanquish doesn’t offer an active sway bar system.
The front and rear suspension of the Dawn uses air springs for a smoother, controlled ride than the Vanquish, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
The Dawn offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Aston Martin doesn’t offer an active suspension on the Vanquish.
The Dawn has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Vanquish doesn’t offer a load leveling suspension.
For a smoother ride and more stable handling, the Dawn’s wheelbase is 14.6 inches longer than on the Vanquish (122.5 inches vs. 107.9 inches).
For better handling and stability, the track (width between the wheels) on the Dawn is 2.6 inches wider in the front and 2.4 inches wider in the rear than on the Vanquish.
Because it has more passenger and cargo room, the EPA rates the Dawn a Compact car, while the Vanquish Volante is rated a Minicompact.
The Dawn has 22 cubic feet more passenger volume than the Vanquish (100 vs. 78).
The Dawn has a larger trunk with its top down the Vanquish Volante (8.6 vs. 8.2 cubic feet).
With its convertible body style, valet key and remote trunk release lockout, the Dawn offers cargo security. The Vanquish’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 Dawn. The Vanquish doesn’t offer locking storage for small valuables.
To make loading and unloading groceries and cargo easier when your hands are full, the Dawn’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The Vanquish doesn’t offer a power or hands-free opening trunk.
The Dawn’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Vanquish doesn’t offer an easy entry system.
The Dawn 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 Vanquish doesn’t offer a heads-up display.
The Dawn’s standard power windows have a locking feature to keep children in the rear seat from operating them. Aston Martin does not offer a locking feature on the Vanquish’s standard power windows.
The Dawn’s 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 Vanquish’s power windows’ switches have to be held the entire time to close them fully.
If the windows are left open on the Dawn the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Vanquish can only operate the windows from inside the vehicle, with the ignition on.
In case of a sudden change of weather, the Dawn has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. The Vanquish doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.
Comfort Entry System standard on the Dawn 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 Aston Martin Vanquish doesn’t offer an advanced key system.
Heated windshield washer nozzles are standard on the Dawn to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Vanquish doesn’t offer heated windshield washer nozzles.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Dawn has standard headlight washers to keep headlight output high. The Vanquish doesn’t offer headlight washers.
While driving with high beams on, sensitive light sensors available for the Dawn detect other vehicles which could be blinded and automatically switch to low beams. The Vanquish doesn’t offer automatic dimming high beams.
To help drivers avoid possible obstacles, the Dawn has standard cornering lights to illuminate around corners when the turn signals are activated. The Vanquish doesn’t offer cornering lights. The Dawn also has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.
The Dawn’s sun-visors swivel front-to-side to block glare from the side windows. The Vanquish’s visors are fixed into the windshield header.
The Dawn has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Vanquish offers an automatic rear view mirror, but its side mirrors don’t dim.
Both the Dawn and the Vanquish have standard heated front seats. The Dawn also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Vanquish.
The Dawn’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Vanquish doesn’t offer dual zone air conditioning.
For greater rear passenger comfort, the Dawn has standard rear a/c vents to keep rear occupants more comfortable. The Vanquish doesn’t offer rear vents.
To keep a safe, consistent following distance, the Dawn offers an optional Active 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 Vanquish doesn’t offer an adaptive cruise control.
With standard voice command, the Dawn offers the driver hands free control of the radio and the navigation computer by simply speaking. The Vanquish doesn’t offer a voice control system.
