40-640: The Envision was first introduced in 2011 as a design concept. It was a small crossover with two large scissor doors opening upward. The concept was a plug-in hybrid with advanced technology such as a solar roof and head-up display. The waterfall grille made it to the production version of the Envision. The Envision was first introduced in China in August 2014, also known by its Chinese name, “Ang Ke Wei” (昂科威). It went on sale in China on October 20. The Envision debuted in

80-422: A vehicle . Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle. Car doors may be manually operated or with power assist supplied by the vehicle. Powered doors or power doors may be found on minivans , luxury vehicles , or modified cars . Car doors are designed to facilitate ingress and egress by car passengers. Unlike other types of doors ,

120-422: A design, is intended to match with the rest of the vehicle's exterior, the central purpose being to add to the overall aesthetic appeal of the vehicle exterior. A vehicle typically has two types of doors: front doors and rear doors. Loosely related are: vehicle hoods and vehicle trunk lids . There are also doors known as a " hatch " (see " door categorization " below). Most vehicle doors are secured closed to

160-457: A driver suddenly opens his or her door immediately in front of the cyclist without first looking to see if it is safe to do so. There are many different types of vehicle doors, including the following: A conventional door, also known as a regular door is hinged at the front-facing edge of the door, and so allows the door to swing outward from the body of the car. These doors are relatively safe, in that if they are opened during forward motion of

200-656: A folded lever mechanism to push and hold the window out from its closed position. Vehicle doors often include brakes , or 'stays', that slow the door down just before it closes, and also prevent the door from opening further than its design specification. The current trend is to have a three-stage door brake. Door brakes exist because the doors on the first vehicles were heavy, so they had to be pushed hard to make them close. Soon after, automotive manufacturers managed to construct lighter doors, but users were used to closing doors with significant force; therefore doors could become damaged. Door brakes were then introduced to slow down

240-471: A manual crank, or switchable electrical motor (electric car windows other than the driver's window can usually be controlled at both the door itself and centrally by an additional control at the driver's position). In the past, certain retracting windows were operated by direct (up or down) pressure, and were held in the up position by friction instead of by an internal lift mechanism. Other cars, particularly older US-manufactured vans , have hinged windows with

280-428: A station wagon or SUV can have four-doors since the opening to the cargo area via the rear tailgate or a hatch is not counted as a door. Passenger cars will typically have two-doors (such as coupes) or four-doors (such as sedans). Some cyclists refer to colliding with an open car door as being " doored " or "door checked". This usually happens when the cyclist is riding alongside a row of parallel-parked cars, and

320-576: A threshold to step over to get in and out. Also called the Jatech rotary drop door, or disappearing car door. One example of a car with disappearing doors is the Lincoln Mark VIII concept car. Various countries have their own regulations for vehicle doors. Global Technical Regulation No. 1, Door locks, is one of the few global regulations. Various countries are members of these regulations, for instance, Australia, Canada, European Union, Japan, Russia, and

360-447: A track. They are commonly used on the sides of minivans , leisure activity vehicles , light commercial vehicles , minibuses , and some buses as this allows a large opening for equipment to be loaded and unloaded without obstructing access. A canopy door sits on top of a car and lifts up in some way, to provide access for passengers. It is similar to an aircraft canopy . There are no set standards to canopies, so they can be hinged at

400-413: A vehicle looks standard from the outside, when the doors are closed. There are different types of scissor doors. The conventional type rotates to 90 degrees. Scissor doors can be powered and they usually are. Vertical lift system (VLS) doors have a scissor door configuration. The biggest difference is that they are designed to initially open slightly outward before opening upward to allow the top edge of

440-403: Is best suited to the situation. Scissor doors are widely noted as a status symbol in popular culture. In 2012, Migos released a track called " Lambo Doors ," in the first line referring to an observer who has never seen such high-status doors. In 2017, Rick Ross released a track called " Lamborghini Doors ", in which he notes a number of objects that are rising up like the titular doors. In

480-466: The Supreme Court of California merged strict product liability with comparative fault . The court affirmed the right of General Motors to introduce evidence that decedent Kirk Daly flew out of his Opel not only because the door popped open, but because he was intoxicated and not wearing a seat belt—but in the same opinion, reversed and remanded for retrial because the jury had not been instructed on

520-537: The 1970s, some vehicles used exposed push buttons to operate the door latch, such as certain Opel models. The unfortunate side effect of this design was that external objects which touched a vehicle during a high-speed spinout could trigger the latch; the door would pop open and centrifugal force would eject any unrestrained vehicle occupants. A death that occurred exactly that way led to the landmark legal case of Daly v. General Motors Corp. , 20 Cal. 3d 725 (1978), in which

560-485: The 2.0L turbo engine, seven active safety technologies, and OnStar/Intellilink connectivity. The trim levels expanded to five for the 2017 model year. In addition to the larger engines offered in North America, Chinese buyers also have the option of a turbocharged 1.5-liter unit. Trim levels for the first generation Envision were known as the 20T and 28T. The 2019 Envision debuted in late 2017 in China, and in 2018 for

600-518: The American-style labeling is occasionally used. Doors that are for passenger egress are counted in North American markets. The openings used for cargo access are generally described by their function - such as hatch, tailgate, or liftgate - depending on the vehicle design. For example, a "two-door hatchback" will have two side doors for passengers and a rear opening to the cargo area. Similarly,

640-513: The Buick Envision Plus is a stretched version of the Envision that serves as a three-row crossover SUV variant of the regular Buick Envision S in China. The wheelbase has been extended to 2,833 mm (111.5 in), resulting in a length of 4,845 mm (190.7 in). The Envision received a facelift for the 2024 model year. It adds new dashboard-mounted digital displays and GM's Super Cruise advanced driver-assistance system , making it

680-499: The Envision features two powertrains: a 2.5-liter four-cylinder with 197 hp (147 kW) and 192 lb⋅ft (260 N⋅m) torque, and a turbo-charged 2-liter four-cylinder engine SAE certified at 252 hp (188 kW) and 260 lb⋅ft (353 N⋅m) torque. Both were initially paired with a third-generation six-speed transmission. For the 2016 model year, the Envision was only available in Premium I and Premium II trim levels, with

720-437: The North American market. It features revised rear styling and tail lights, stop/start calibration, and new seating design. The transmission for the 2.0-litre turbo engine was upgraded to a 9-speed automatic. The 2020 Envision facelift debuted in early 2020 in China, and would be sold alongside the second generation models called the Envision S in China. It features revised front and rear end styling. In May 2020, GM introduced

760-576: The TV series Silicon Valley , the character Russ Hanneman remarks that he feels poor when he has regular car doors, rather than doors that go "like this" (gesturing as if his arms were gull-wing doors) or "like this" (gesturing as if his arms were scissor doors), leading to other commentators referring to scissor doors as "billionaire doors". Car door A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting

It went on sale in the United States in the summer of 2016, making it the first Chinese-built GM vehicle to be sold in America. It was initially offered with all-wheel drive, and subsequently with optional front-wheel drive for model year 2017. The North American version of

840-466: The United States and Canada markets due to the President Donald Trump's tariffs on Chinese goods should its request to seek a tariff waiver for the vehicles be denied. The automaker saw the exemption as "the only way" to continue offering the vehicle to U.S. consumers, according to GM President Dan Ammann . The exemption was denied on May 29, 2019, but GM opted to pay the tariffs without raising

880-515: The door just before the door closed to prevent damage; these soon became standard. Hatchback and estate or station wagon vehicles are typically described as 'three-door' or 'five-door' models in Europe and some other parts of the world. In the case of saloons or sedans and coupés , the boot/trunk lid is not counted as a door by definition because it is for a separate storage compartment - these cars are marketed as 'two-door' or 'four-door'. In Europe,

920-423: The door to clear the door frame and A-pillar . Although butterfly doors also move upwards and outwards, VLS doors are not the same as butterfly doors as VLS doors move outward only a small degree compared to butterfly doors. Although conventional scissor doors rotate to 90 degrees, some can rotate up to 130 degrees; these are commonly used for modified cars. Such scissor doors have the benefit of not obstructing

960-528: The doors was a Lamborghini , Gandini's Countach ; the sports car's wide chassis created similar problems to those found on the Carabo, calling for the unusual door configuration. This sports car was quite impractical for real life, as due to unusual design it was impossible to backup without doors open wide. So, such doors were originally offered as a practical measure that helped the driver. Besides, traditional swing-open doors would make it more difficult to get out of

1000-415: The driver when the door is not closed. The door light is standard equipment on all cars. In American cars from the 1950s-1990s, they had buzzers or "door dingers" that sounded, along with the check light, whenever any door is open. Most vehicle doors have windows , and most of these may be opened to various extents. Most car door windows retract downwards into the body of the doors and are opened either with

1040-406: The entrance or exit to the car as much as conventional scissor doors. VLS doors also can be made to rotate to 130 degrees. Some aftermarket example scissor doors are also designed so they can open either vertically (scissor door) or horizontally (conventional door), as the user chooses. Such doors allow the user to gain the benefits of both types of door, choosing to open the doors in whichever style

1080-557: The exterior side of the vehicle door contrasts in its design and finish from its interior side (the interior part is typically equipped with a door card (in British English) or a door panel (in American English) that has decorative and functional features. The exterior side of the door is designed of steel or other material like the rest of the vehicle's exterior. In addition, its decorative appearance, typically colored with

1120-403: The first Buick available with the technology. In 2017, the Envision was Buick's third bestselling model in the U.S. with sales of just over 41,000 units. Sales in the U.S. dropped 27% in 2018 but rebounded slightly in 2019. In 2020, Envision was the only Buick model in the U.S. to see a sales increase over 2019. On August 6, 2018, General Motors announced that it might withdraw the Envision from

The second generation Envision now shares the E2XX platform with the Cadillac XT4. Launched during the 2021 Shanghai Auto Show,

1200-402: The front, side or back - although hinging at the front is most common. Canopy doors are rarely used on production cars , but are frequently used on the 'closed' variants of Le Mans Prototype endurance race cars. They are also sometimes used on concept cars . A disappearing door slides down and under the vehicle. This type makes the whole side of the passenger compartment open, and only leaves

1240-556: The implementation of scissor doors, which are sometimes colloquially referred to as "Lambo doors". Today many aftermarket companies are specialized in production of scissor door conversion kits for regular production cars that originally come with regular doors. A common scissor door conversion kit (also known as a "Lambo-door" kit) includes model specific redesigned door hinges and gas filled shocks. Such kits are usually bolt-on or weld on and require some modifications to front bumpers and door panels. Original door panels are not replaced, so

1280-427: The price on the vehicle. Scissor doors Scissor doors (also called flap doors , wing doors , beetle-wing doors , turtle doors , switchblade doors , swing-up doors , upswing doors , Lamborghini doors , and Lambo doors ) are automobile doors that rotate vertically at a fixed hinge at the front of the door, rather than outward as with a conventional door. The first vehicle to feature scissor doors

1440-510: The vehicle body with latches that may be locked to prevent unauthorized access from the exterior. There are a variety of car door locking systems. Door locks may be manually, or automatically operated, and may be centrally or individually operated. Also, they may be operated by remote control, with the transmitter often integrated into the main vehicle access and a key for the ignition. Additionally, rear passenger doors are frequently fitted with child safety locks to prevent children from exiting

1480-724: The vehicle due to high door sills. The doors were used on the Countach's successor, the Diablo , on its replacement, the Murciélago , and on a low-production run derivative of the Murciélago called the Reventón . The Revuelto is the latest Lamborghini car to feature these doors. They are trademarked. Having used the exotic door style for several of its cars, the Italian manufacturer has become synonymous with

1520-415: The vehicle unless the door is opened from the exterior. These are also frequently used on police cars, to prevent suspect criminals from escaping whilst in police custody. Vehicle door latches on practically all vehicles today are usually operated by use of a handle which requires the user to pull , lift , or tug —with some force towards themselves—rather than push . There is a reason for this. As late as

1560-734: The vehicle, the wind resistance will work against the opening door, and will effectively force its closure. A suicide door is hinged on its trailing edge. The term "suicide door" was coined due to the potential for the door to fly open when the latch was released while the car was in motion. Scissor doors rotate vertically upward and are hinged at or near the end of the windshield. They are used in Lamborghinis, Alfa Romeos, and other brands. Butterfly doors are similar to scissor doors, but while scissor doors move up, butterfly doors also move outwards, which makes for easier entry/exit, and saves space. Gull-wing doors are hinged on their uppermost edge, at

1600-409: Was the 1968 Alfa Romeo Carabo concept car, designed by Bertone 's Marcello Gandini . The door style was dictated by Gandini's desire for an innovative design, and by his concern over the car's extremely poor rear visibility. In order to reverse the car, the driver would be able to lift the door and lean his upper body out of the hatch in order to see behind the car. The first production car to feature
