Rear-engined
In automobile design, a rear-engine design layout places the engine at the rear of the vehicle. The center of gravity of the engine itself is behind the rear axle. This is not to be confused with the center of gravity of the whole vehicle, as an imbalance of such proportions would make it impossible to keep the front wheels on the ground. Rear-engined vehicles almost always have a rear-wheel drive car layout, but some are four wheel drive. This layout has the following features: *Packaging: since there is no need for a transmission tunnel, the floor can be flat. *Rear traction: having the engine located over the driven wheels increases downward pressure, which is helpful for grip on loose surfaces, although can be prone to oversteer. *Simplicity of manufacture: the engine is near the driven wheels, and the transmission can be merged with the differential to save space. This layout was once popular in small, inexpensive cars and light commercial vehicles. Today most car makers hav ...

Mitsubishi I
The is a kei car from automaker Mitsubishi Motors, first released in January 2006, twenty eight months after its debut at the 2003 Frankfurt Motor Show. It is the first four-door automobile since the 1960s to employ a " rear midship" setup with the engine behind the passengers, in an attempt to improve safety and interior space without enlarging the overall exterior. The innovative layout and styling of the i proved an immediate critical and commercial success, exceeding Mitsubishi's initial sales targets by 20 percent and winning thirteen awards in its first year. Although designed with the Japanese ''keijidōsha'' light automobile class in mind, the attention it generated led to its subsequent introduction in right hand drive markets in Asia, Oceania and Europe. It is also used as a basis of the 2009 i-MiEV battery electric vehicle. Concepts: i, Se-Ro Two prototypes were exhibited during the car's development. The first was the "i" Concept, which debuted at the 60th ...

Rear-engine Mercedes-Benz
From 1931 to 1939, Daimler-Benz AG produced three cars ( Mercedes-Benz 130, 150 and 170 H) with rear engine as well as a few prototypes. The production numbers remained quite low for each of these models, especially compared to the production of classical front-engine Mercedes cars. Development and prototypes (W17/W25D) At the beginning of the 1930s, inspired by modern streamlined shapes, there were attempts to move car engines from the forward compartment to the rear of the car. Such a move allows a reduction in the volume of the front compartment. At the same time, the voluminous rear provides a lot of space above and behind the rear axle. Moreover, when engines are rear mounted, the drive shaft is eliminated. The most famous such development was with the 1930s Tatra cars under the leadership of Hans Ledwinka. In 1930, Daimler-Benz entrusted Hans Nibel with the development of a small rear-engined car, starting from the same principles. In 1931, working with Max Wagner, the typ ...

Fiat 500
The Fiat 500 ( it, Cinquecento, ) is a rear-engined, four-seat, small city car that was manufactured and marketed by Fiat Automobiles from 1957 until 1975 over a single generation in two-door saloon and two-door station wagon bodystyles. Launched as the ''Nuova (new) 500'' in July 1957, as a successor to the 500 "Topolino", it was an inexpensive and practical small car. Measuring long, and originally powered by a 479 cc two-cylinder, air-cooled engine, the 500 was smaller than Fiat's 600, launched two years earlier, and is considered one of the first purpose-designed city cars. In 1959, Dante Giacosa received a Compasso d'Oro industrial design prize for the Fiat 500. It was the first time when it was awarded to an automotive industry. In 2007, the 50th anniversary of the Nuova 500's launch, Fiat launched another new 500, stylistically inspired by the 1957 Nuova 500, featuring a front-mounted engine and front-wheel drive. In 2017 Fiat celebrated the 60th anniver ...

Hillman Imp
The Hillman Imp is a small economy car that was made by the Rootes Group and its successor Chrysler Europe from 1963 until 1976. Revealed on 3 May 1963, after much advance publicity, it was the first British mass-produced car with the engine block and cylinder head cast in aluminium. Being a direct competitor to the BMC's Mini, it used a space-saving rear-engine, rear-wheel-drive layout to allow as much luggage and passenger capacity as possible in both the rear and the front of the car. It used a unique opening rear hatch to allow luggage to be put into the back seat rest. It was the first mass-produced British car with the engine in the back and the first to use a diaphragm spring clutch. The baulk-ring synchromesh unit for the transaxle compensated for the speeds of gear and shaft before engagement, from which the Mini had suffered during its early production years. It incorporated many design features which were uncommon. Among them were a folding rear bench seat, ...

Low-floor Bus
A low-floor bus is a bus or trolleybus that has no steps between the ground and the floor of the bus at one or more entrances, and low floor for part or all of the passenger cabin. A bus with a partial low floor may also be referred to as a low-entry bus or seldom a flat-floor bus in some locations. Low floor refers to a bus deck that is accessible from the sidewalk with only a single step with a small height difference, caused solely by the difference between the bus deck and sidewalk. This is distinct from high-floor, a bus deck design that requires climbing one or more steps (now known as step entrance) to access the interior floor that is placed at a higher height. Being low-floor improves the accessibility of the bus for the public, particularly the elderly and people with disabilities, including those using wheelchairs and walkers. Almost all are rear-engine, rear-wheel-drive layout with no drive shaft. Configuration Low-floor and low-entry buses Low-floor buses are ge ...

Fiat 126
The Fiat 126 (Type 126) is a four-passenger, rear-engine, city car manufactured and marketed by Fiat over a twenty-eight year production run from 1972 until 2000, over a single generation. Introduced by Fiat in October 1972 at the Turin Auto Show, the 126 replaced the Fiat 500, using major elements from its design. A subsequent iteration, marketed as the ''126 Bis'', used a horizontally oriented, water-cooled engine and featured a rear hatchback. The majority of 126s (some 3.3 million) were manufactured in the Tychy plant in Bielsko-Biała, Poland and were marketed as the Polski Fiat 126p in many markets. Fiat stopped marketing the 126 in 1993 in favor of its new front-engined Cinquecento. Total production reached approximately 4.7 million units. In Poland, the car became a people's car, and a cultural icon, earning the nickname ''Maluch'', meaning "The Little One" or "Toddler", a name that eventually became official in 1997, when 'Maluch' started appearing, badged on the rear of ...

Car Layout
The powertrain layout of a motorised vehicle such as a car is often defined by the location of the engine and drive wheels. Layouts can roughly be divided into three categories: front-wheel drive (FWD), rear-wheel drive (RWD) and four-wheel drive (4WD). Many different combinations of engine location and driven wheels are found in practice, and the location of each is dependent on the application for which the vehicle will be used. Front-wheel-drive layouts Front engine, front-wheel drive The ''front-engine, front-wheel-drive'' layout (abbreviated as FF layout) places both the internal combustion engine and driven wheels at the front of the vehicle. This is the most common layout for cars since the late 20th century. Mid-engine, front-wheel drive Some early front-wheel drive cars from the 1930s had the engine located in the middle of the car. Rear-engine, front-wheel-drive A rear-engine, front-wheel-drive layout is one in which the engine is between or behind the rear ...

Porsche 911
The Porsche 911 (pronounced ''Nine Eleven'' or in german: Neunelfer) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged.Corlett, p. 12 The engines were air-cooled until the introduction of the 996 series in 1998. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models. In a 1999 poll to determine the Car of the Century, the 911 was ...

DMC DeLorean
The DMC DeLorean is a rear-engine two-passenger sports car manufactured and marketed by John DeLorean's DeLorean Motor Company (DMC) for the American market from 1981 until 1983—ultimately the only car brought to market by the fledgling company. The DeLorean is sometimes referred to by its internal DMC pre-production designation, DMC-12. However, the DMC-12 name was never used in sales or marketing materials for the production model. Designed by Giorgetto Giugiaro and noted for its gull-wing doors and brushed stainless-steel outer body panels, the sports car was also noted for a lack of power and performance incongruous with its looks and price. Though its production was short-lived, the DeLorean became widely known after it was featured as the time machine in the ''Back to the Future'' films. With the first production car completed on January 21, 1981, the design incorporated numerous minor revisions to the hood, wheels and interior before production ended in late De ...

BMW 700
The BMW 700 is a small rear-engined car which was produced by BMW in various models from August 1959 to November 1965. It was the first BMW automobile with a monocoque structure. The 700 was a sales success at a time when BMW was close to financial ruin. The 700 was also successful in its class in motorsport, both in its stock form and as the basis of a racing special called the 700RS. More than 188,000 were sold before production ended in November 1965. Upon discontinuing the 700, BMW left the economy car market. Concept, design, and engineering Wolfgang Denzel, the distributor of BMW cars in Austria, commissioned Giovanni Michelotti to prepare concept sketches based on a lengthened BMW 600 chassis.''BMW - Bavaria's Driving Machines'', Norbye, pp. 124-125 In January 1958, Denzel was awarded a development contract for the 700. Denzel presented a prototype to BMW's management in July 1958. The concept, a two-door coupé with a slanted roof, was generally well received, ...

Fiat 600
The Fiat 600 ( it, Seicento, ) is a rear-engine, water-cooled city car, manufactured and marketed by Fiat from 1955 to 1969 — offered in two-door fastback sedan and four-door Multipla mini MPV body styles. Measuring only long, its all-new design was the first unibody and rear-engined Fiat, and was priced the equivalent of about €6,700 or US$7300 in today's money (590,000  lire then). The total number produced from 1955 to 1969 at the Mirafiori plant in Turin was 2,695,197. The 1955 Fiat 600 formed the blueprint for the 2nd generation "Nuova" (New) 500, launched two years later – which was even smaller, at and, although rounder, largely copied the 600s layout and shape. Later, the 600 also formed the platform for the larger 850 saloon, launched in 1964, which coexisted with the 600 in Fiats line-up for five years, until the 600 was cancelled. During the 1950s, '60s, '70s and '80s, many units were built in countries such as Spain (as SEAT 600), where it became th ...

Automobile Design
Automotive design is the process of developing the appearance (and to some extent the ergonomics) of motor vehicles - including automobiles, motorcycles, trucks, buses, coaches, and vans. The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines also included within automotive engineering, however, design roles are not associated with requirements for professional- or chartered-engineer qualifications. Automotive design in this context focuses primarily on developing the visual appearance or aesthetics of vehicles, while also becoming involved in the creation of product concepts. Automotive design as a professional vocation is practiced by designers who may have an art background and a degree in industrial design or in transportation design. For the terminology used in the field, see the glossary of automotive design. Design elements The task of the design team is usually split into three main ...
