Lotus Esprit
The Lotus Esprit is a British sports car that was built by Lotus Cars at their Hethel factory in England between 1976 and 2004. It was among the first of designer Giorgetto Giugiaro's polygonal "folded paper" designs. Background In 1970 Tony Rudd, who had arrived at Lotus the previous year, proposed two new model development projects. The first, Project M50, resulted in the 1974 Elite. The second, Project M70, meant to develop a successor to the Europa which, like the Europa, was to be a two-door fixed-head mid-engine coupé. A meeting between Colin Chapman and Giugiaro was arranged in 1971 by designer Oliver Winterbottom, who also suggested that Giugiaro use his Maserati Boomerang concept as the inspiration for the new Lotus. Work began on the new car in mid-1971 with production of a 1:4 scale model. According to Italdesign, Chapman was disappointed with the wind-tunnel test results with the model and halted the project, but the Italian coachbuilder pressed on and built a f ...

Lotus 900 Series
The Lotus 900 series is a family of internal combustion engines designed and built by Lotus Cars of United Kingdom. Successor to the Lotus-Ford Twin Cam, the 900 was the first complete engine developed by Lotus. The engine was built from 1972 to 1999. Background As early as 1964, Lotus recognized the need to find a replacement for the Lotus Twin Cam engine. Colin Chapman issued a brief that listed the features to be required in a new engine, including 'high efficiency, flexibility, torque and smoothness which was suitable for hand assembly'. Unable to find this combination in any existing engine, the company used outside consultants and internal resources to define the characteristics of the next Lotus engine. After having rejected a 120° V6 due to being too wide for Lotus' chassis and a 60° V6 as too tall for the intended bodywork, the engineers determined that a 2-litre inline-four engine was the optimal choice. This future engine would have four valves per cylinder (16 val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concept Car
A concept car (also known as a concept vehicle, show vehicle or prototype) is a car made to showcase new styling and/or new technology. They are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be mass-produced. General Motors designer Harley Earl is generally credited with inventing the concept car, and did much to popularize it through its traveling Motorama shows of the 1950s. Concept cars never go into production directly. In modern times all would have to undergo many changes before the design is finalized for the sake of practicality, safety, regulatory compliance, and cost. A " production-intent" prototype, as opposed to a concept vehicle, serves this purpose. Design Concept cars are often radical in engine or design. Some use non-traditional, exotic, or expensive materials, ranging from paper to carbon fiber to refined alloys. Others have unique layouts, such as gullwing doors, 3 or 5 (or more) wheels, or spe ...

Fiat X1/9
The Fiat X1/9 is a two-seater mid-engined sports car designed by Bertone and manufactured by Fiat from 1972–1982 and subsequently by Gruppo Bertone from 1982–1989. With a transverse engine and gearbox in a mid-mounted, rear-wheel drive configuration, the X1/9 was noted for its balanced handling, retractable headlights, lightweight removable hardtop which could be stowed under the bonnet, front and rear storage compartments — and for being the first Fiat to have been designed from its conception to meet US safety regulations. History Design and development The X1/9 was developed from the 1969 Autobianchi A112 Runabout concept, with styling by Bertone under chief designer Marcello Gandini. Even though the Runabout was named for the Autobianchi A112, it was powered by a version of the brand new Fiat 128 SOHC engine. The Runabout featured a distinctive wedge shape and took many styling cues from contemporary power-boat design. Though the more extreme features of the R ...

Maserati Merak
The Maserati Merak (''Tipo AM122'') is a mid-engined 2+2 sports car produced by Maserati between 1972 and 1983. The Merak was closely related to the Maserati Bora, sharing part of its structure and body panels, but was powered by a 3.0 L V6 in place of the latter's 4.7 L V8. The extra cabin space gained by fitting a smaller and more compact powertrain was used to carve out a second row of seats—suitable for children or very small adults—making the Merak not just a less expensive alternative to the Bora but also a 2+2. History The Maserati Merak was introduced at the 1972 Paris Auto Show, over a year after the Bora. The model was named after Merak, a star in the constellation of Ursa Major. The Merak shares the front part of its bodyshell with the Bora up to the doors. The front ends differ, mainly by the use of dual chrome bumpers on the Merak, in place of twin trapezoidal grilles on the Bora, but the similarities end at the B-pillar. Giorgetto Giugiaro at Italdesign was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citroën SM
The Citroën SM is a high-performance coupé produced by the French manufacturer Citroën from 1970 to 1975. The SM placed third in the 1971 European Car of the Year contest, trailing its stablemate Citroën GS, and won the 1972 ''Motor Trend'' Car of the Year award in the U.S. History In 1961, Citroën began work on 'Project S' – a sports variant of the Citroën DS. As was customary for the firm, many running concept vehicles were developed, increasingly complex and upmarket from the DS. At some stage in the 9-year project, it evolved from developing a faster variant of the 1955 DS to developing an entirely new, thoroughly engineered car – in terms of engineering effort, a replacement for the high volume DS model. Citroën purchased Maserati in 1968 with the intention of harnessing Maserati's high-performance engine technology to produce a true Gran Tourer car, combining the sophisticated Citroën suspension with a Maserati V6. The result was the Citroën SM, first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backbone Chassis
Backbone tube chassis is a type of automobile construction chassis that is similar to the body-on-frame design. Instead of a two-dimensional ladder-type structure, it consists of a strong tubular backbone (usually rectangular in cross section) that connects the front and rear suspension attachment areas. A body is then placed on this structure. It was first used in the English Rover 8hp of 1904 and then the French Simplicia automobile in 1909. The backbone chassis was extensively developed by Hans Ledwinka who used it in greater numbers on the Tatra 11 and subsequent vehicles. Ledwinka later used backbone frame with central tube and axles with swinging driveshafts on Tatra trucks, became known as ''Tatra-concept''. Design The truck backbone chassis is a design feature of Czech Tatra heavy trucks (cross-country, military etc.). Hans Ledwinka used this style of chassis for the Tatra 11 car in 1923. He then developed the design on trucks with 6x4 model Tatra 26, which had ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Straight-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...
