A vehicle accessory attached to the back of a vehicle’s liftgate or trunk lid used to add a stylish aesthetic or improve its aerodynamics. Spoilers are usually comprised of at least one airfoil supported by an upright on either side to allow airflow both under and over it. This disrupts the air as a vehicle moves to decrease its lift and increase its stability. These devices are regularly used in sports cars and professional auto racing for added stability at high speeds.
An incentive cash repayment provided by automotive manufacturers to consumers which lowers the net price of a vehicle purchase. Cash amounts will vary based on the exact rebate offered by manufacturers. Limited time offers can provide an added incentive for consumers to buy within a given period, and they can be used to amplify sales or reach target goals.
A process where owners of particular vehicle years, makes, and models are notified by their respective manufacturers of a serious defect in the construction, operation, engine, or other component. These serious defects may have a direct impact on the safety of a vehicle and should be repaired immediately by the manufacturer or an authorized service department. The repairs must be completed with no charge to the consumer for the service. Independent safety testing is conducted by the National Highway Traffic Safety Administration for all new vehicles produced. When safety defects are detected, the agency issues a notice to the manufacturer that a recall is necessary. Once the manufacturer begins the process, the NHTSA also monitors the manufacturer’s progress and effectiveness at issuing the notice and completing the required vehicle service. Usually, recalls will not affect an entire line of models produced in a given year and only experience problems with specific makes and model types. Vehicle owners can review current and past recalls on either their manufacturer’s or the NHTSA website. This safety information should be regularly reviewed as recalls may occur several years after a specific make or model is released.
An announcement by a manufacturer sent to vehicle owners, lessees, and dealerships which notifies them of unsafe defects for specific vehicular years, makes, and models. The notice informs them of the specific defect, the potentially unsafe effects, and where to go to receive free repairs to correct the issue.
Recommended Fuel Type
A vehicle’s optimum type of fuel recommended by the manufacturer for the most efficient operation. Each type is distinguished by its octane rating such as 87, 89, and 93. The ideal fuel type provides the best engine performance.
Braking method which aids in the deceleration of an electric or hybrid vehicle while adding energy to the battery. The vehicle’s electric motor switches modes from drive or output to generator mode while braking is engaged. This process transfers a portion of the kinetic energy produced by the vehicle into electrical energy which provides some recharge power to the battery. This process captures energy which would have otherwise been lost to improve the efficiency of vehicle operation.
A vehicle feature which allows a driver’s electronic key fob to remotely control an engine startup. This is often an aftermarket feature installed on vehicles after the initial manufacturing.
Remote Trunk Release
A vehicle feature which controls the power-activated release of a trunk using an electronic key fob, mobile-synced smart key, or other remote control option. This option is frequently included as a standard feature on several vehicle models.
Remote Window Operation
Remote operated control for a vehicle’s windows by use of a portable key fob, mobile-synced smart key, or other device. This option is frequently available as an aftermarket installation or an additional feature not included in the initial manufacturing.
A range of natural energy sources which can be naturally replenished without the need for fossil fuel or other resource consumption. Common options include wind power, solar power, bio-fuels, and hydrogen. Use of renewable energy can help reduce the environmental impact of combustion engines and decrease the reliance on fossil fuel sources within the automotive industry.
A set of tools and equipment that most commonly refers to tire repair. Tire repair kits are comprised of an emergency sealant, a disposable tire refilling agent, a pump in cases where there is no other refilling method, and a gauge to read current tire pressure.
A valuation of property within claims that determines the worth of insured property by only referring to current prices for a similar replacement. This amount does not factor in any additional factors such as the current condition of the property, its depreciation, and the mileage or service record when referring to vehicles. This method differs from Actual Cash Value which also incorporates additional factors to determine its current worth. Refer to “Actual Cash Value” for more information.
Required Fuel Type
The minimum threshold of acceptable fuel types which are outlined by a vehicle’s manufacturer. This minimum is determined based on a fuel’s octane rating to set a floor on acceptable fuel quality for optimal vehicle performance.
A leasing company’s assessment of the projected value of a vehicle at the end of a leasing term. The value itself is determined based on factors such as consumer demand, model popularity, and reliability. The amount also helps to determine the monthly lease payment alongside interest and other fees. The higher the residual value after a leasing period, the lower the monthly payment will be for the lessee. This is because a leased vehicle which holds its value longer can continue to earn more money in its lifespan after a lease and when it is resold in the used car or auction marketplace.
Retained Accessory Power
A vehicle-equipped feature which continues to provide power to various mechanisms and accessories after the vehicle has stopped and the key has been removed from the ignition. Power remains supplied to these components – such as windows or the entertainment system – until a door is opened or after a set period of time has passed. For example, an occupant can roll an electric window up after the key has been removed without having to replace it in the ignition to activate the power.
Side view mirrors which can be folded inward or moved closer to the chassis of a vehicle to prevent accidental damage or while moving in extremely tight spaces. It is commonly used while parking in small spaces, in automatic car washes, or to fit a vehicle in an extremely narrow garage.
Reverse Tilt Mirrors
Electric-powered side view mirrors which automatically tilt downward while a vehicle is placed in reverse gear. The downward tilt provides greater visibility toward the rear chassis while parallel parking. It enhances the overall safety potential while reducing the chances of a reverse collision.
A service which provides assistance to a driver when a vehicle is disabled or inoperable. The services are provided by particular manufacturers and may vary based on the make or model.
A series of vehicle devices which all work in unison to prevent or reduce the damage caused during a rollover accident. These devices may also improve the safety of occupants in these accidents.
