Front-engine
Front-engine design is an automotive design where the engine is in the front side of the car, connected to the wheels via a drive shaft. The main types of Front engine design are: * Front-engine, rear-wheel-drive layout, the traditional automotive layout for most of the 20th century. * Front-engine, front-wheel-drive layout, which became dominant in passenger cars by the late 20th century. * Front-engine, four-wheel-drive layout. Advantage of front engine design is better cabin space for passengers, and also bigger boot space. Disadvantage is that more weight of the car goes on front wheels and less weight goes on the rear wheels, that causes understeer. https://www.hotcars.com/things-you-forgot-about-1983-toyota-supra/ See also *Mid-engine design *Rear-engine design In automobile design, a rear-engine design layout places the engine at the rear of the vehicle.

Mid-engine Design
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive com ...

Front-engine, Front-wheel-drive Layout
In automotive design, a front-engine, front-wheel-drive (FWD) layout, or FF layout, places both the internal combustion engine and driven roadwheels at the front of the vehicle. Usage implications Historically, this designation was used regardless of whether the entire engine was behind the front axle line. In recent times, the manufacturers of some cars have added to the designation with the term ''Front mid-engine, front-wheel-drive layout, front-mid'' which describes a car in which the engine is in front of the passenger compartment but behind the front axle. The engine positions of most pre–World War II, World-War-II cars are ''front-mid'' or on the front axle. This layout is the most traditional form and remains a popular, practical design. The engine, which takes up a great deal of space, is packaged in a location passengers and luggage typically would not use. The main deficit is weight distribution—the heaviest component is at one end of the vehicle. Car handling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front-engine, Four-wheel-drive Layout
In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This car layout, layout is typically chosen for better control on many surfaces, and is an important part of rallying, rally racing, as well as off-roading, off-road driving. In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain. The Weak architecture produces a vehicle with a large powersplit between the front and rear powertrains, while the Strong architecture recommends a vehicle with more similar power and torque requirements for the front and rear. Most four-wheel-drive layouts are front-engined and are derivatives of earlier Front-engine, rear-wheel-drive layout, front-engine, rear-wheel drive, or Fr ...

Front-engine, Rear-wheel-drive Layout
A front-engine, rear-wheel-drive layout (FR), also called Système Panhard is a powertrain layout with an engine in front and rear-wheel-drive, connected via a drive shaft. This arrangement, with the engine straddling the front axle, was the traditional automobile layout for most of the pre-1950s automotive mechanical projects. It is also used in trucks, pickups, and high-floor buses and school buses. Front mid-engine, rear-wheel-drive layout A front mid-engine, rear-wheel-drive layout (FMR) places the engine in the front half of the vehicle but ''behind'' the front axle, which likewise drives the rear wheels via a driveshaft. Shifting the engine's center of mass rearward aids in front/rear weight distribution and reduces the moment of inertia, both of which improve a vehicle's handling. FMR cars are often characterized by a long hood and front wheels that are pushed forward to the corners of the vehicle, close to the front bumper. 2+2-style grand tourers often have FMR l ...

Toyota Corolla (E210) Sedan IMG 4190
The is a series of compact cars (formerly subcompact) manufactured and marketed globally by the Japanese automaker Toyota Motor Corporation. Introduced in 1966, the Corolla was the best-selling car worldwide by 1974 and has been one of the best-selling cars in the world since then. In 1997, the Corolla became the best-selling nameplate in the world, surpassing the Volkswagen Beetle. Toyota reached the milestone of 50 million Corollas sold over twelve generations in 2021. The name '' Corolla'' is part of Toyota's naming tradition of using names derived from the Toyota Crown for sedans, with ''" corolla"'' Latin for "small crown". The Corolla has always been exclusive in Japan to '' Toyota Corolla Store'' locations, and manufactured in Japan with a twin, called the Toyota Sprinter until 2000. From 2006 to 2018 in Japan and much of the world, and from 2018 to 2020 in Taiwan, the hatchback companion had been called the Toyota Auris. Early models were mostly rear-wheel drive, whi ...

Automotive 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 a ...

Understeer
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of the vehicle to changes in steering angle associated with changes in lateral acceleration. This sensitivity is defined for a level road for a given steady state operating condition by the Society of Automotive Engineers (SAE) in document J670SAE International Surface Vehicle Recommended Practice, "Vehicle Dynamics Terminology", SAE Standard J670, Rev. 2008-01-24 and by the International Organization for Standardization The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries.

Rear-engine Design
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 have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
