General Motors Ultralite
The General Motors Ultralite was a 1992 low emission vehicle concept car intended to demonstrate the benefits of advanced materials and low fuel consumption. It was rated at by the EPA, but could achieve at a steady state cruising speed of 50 mph. The carbon fiber shell was fabricated by Scaled Composites and it weighed only 420 pounds (191 kg). The total weight of the car was 1,400 pounds (635 kg). The car had gull-wing doors and no B-pillar. The drag coefficient, Cd, was 0.19, significantly lower than that of production cars of the decade. Its three-cylinder 1.5 L two-stroke engine could produce 111 hp (83 kW), which made a speed of 135 mph (217 km/h) possible. The car could accelerate from 0 to 60 mph (97 km/h) in less than eight seconds. The shape was reminiscent of the Ford Probe concept, and the Ultralite presaged the production General Motors EV1 electric vehicle and other production models. In popular culture Due to t ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

Electric Vehicle
An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). EVs include, but are not limited to, road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft. For road vehicles, together with other emerging automotive technologies such as autonomous driving, connected vehicles and shared mobility, EVs form a future mobility vision called Connected, Autonomous, Shared and Electric (CASE) Mobility. EVs first came into existence in the late 19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time.

General Motors EV1
The General Motors EV1 was an electric car produced and leased by General Motors from 1996 to 1999. It was the first mass-produced and purpose-designed electric vehicle of the modern era from a major automaker and the first GM car designed to be an electric vehicle from the outset. The decision to mass-produce an electric car came after GM received a favorable reception for its 1990 Impact electric concept car, upon which the design of the EV1 drew heavily. Inspired partly by the Impact's perceived potential for success, the California Air Resources Board (CARB) subsequently passed a mandate that made the production and sale of zero-emissions vehicles (ZEV) a requirement for the seven major automakers selling cars in the United States to continue to market their vehicles in California. The EV1 was made available through limited lease-only agreements, initially to residents of the cities of Los Angeles, California, and Phoenix and Tucson, Arizona. EV1 lessees were officially part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Probe
The Ford Probe is a liftback coupé produced by Ford, introduced in 1988 and produced until 1997. The Probe was the result of Ford's collaboration with its longtime Japanese partner Mazda, and both generations of Probe were derived from the front-wheel drive Mazda G platform that underpinned the Mazda Capella. The Probe succeeded the Ford EXP, and the instrument cluster of the first-generation Probe and pop-up headlight mechanisms were borrowed from the FC Series RX-7. Based on the Mazda MX-6 as a sport compact coupe, the Probe was intended to fill the market niche formerly occupied by the Capri in Europe, and it was originally intended to be the fourth generation Ford Mustang in the North American market as a direct competitor with the Acura Integra, Isuzu Piazza, Nissan 200SX, and the Toyota Celica. During that time, Ford's marketing team had deemed that a front-wheel drive platform (borrowed Mazda GD and GE platforms) would have lower costs for production, and also because t ...

Automobile Drag Coefficient
The drag coefficient is a common measure in automotive design as it pertains to aerodynamics. Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics. Aerodynamic drag increases with the square of speed; therefore it becomes critically important at higher speeds. Reducing the drag coefficient in an automobile improves the performance of the vehicle as it pertains to speed and fuel efficiency. There are many different ways to reduce the drag of a vehicle. A common way to measure the drag of the vehicle is through the drag area. Reducing drag The reduction of drag in road vehicles has led to increases in the top speed of the vehicle and the vehicle's fuel efficiency, as well as many other perfor ...

Pillar (car)
The pillars on a car with permanent roof body style (such as four-door sedans) are the vertical or nearly vertical supports of its window area or greenhouse—designated respectively as the ''A, B, C'' and (in larger cars such as 4-door station wagons and sport utility vehicles) ''D-pillar,'' moving from front to rear, in profile view. Nomenclature Car pillars are components that support the structure of an enclosed automobile body. This is similar to that of a house with pillars supporting the roof over the floor. Car pillars are designed to stand in near vertical or inclined positions to support the roof. The consistent alphabetical designation of a car's pillars provides a common reference for design discussion and critical communication. This is used by insurance companies to identify damaged components and rescue teams employ pillar nomenclature to facilitate communication when cutting wrecked vehicles, as when using the jaws of life. The A-pillars on each side of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gull-wing Door
In the automotive industry, a gull-wing door, also known as a falcon-wing door or an up-door, is a car door that is hinged at the roof rather than the side, as pioneered by Mercedes-Benz 300 SL, first as a race car in 1952 ( W194), and then as a production sports car in 1954. Opening upwards, the doors evoke the image of a seagull's wings. In French, they are (butterfly doors). The papillon door was designed by Jean Bugatti for the 1939 Type 64, 14 years before Mercedes-Benz produced its similar, famous 300 SL gullwing door. The papillon door is a precursor to the gullwing door, and is slightly different in its architecture, but is often overlooked when discussing gull-wing design. Conventional car doors are typically hinged at the front-facing edge of the door, with the door swinging outward horizontally. Apart from the Mercedes-Benz 300 SL of the mid-1950s, Mercedes-Benz SLS and the experimental Mercedes-Benz C111 of the early 1970s, the best-known examples of road-cars w ...
