Audi Q4 E-tron
The Audi Q4 e-tron is a battery electric compact luxury crossover SUV produced by Audi. It is based on Volkswagen Group's electric MEB platform and is the fourth fully-electric model in the Audi e-tron series after the Audi e-tron, e-tron GT and Q2L e-tron. Production began in March 2021, with the production version being unveiled in April 2021. Overview The Q4 e-tron was first shown as a near-series concept vehicle at Geneva Motor Show in 2019. Positioned in what Audi calls the "heart of the market", the compact SUV segment, its length of is slightly shorter than that of the Audi Q5, although Audi claims that the Q4 e-tron offers comparable interior space. With , the front overhangs are relatively short, allowing for a wheelbase of while maintaining more compact overall dimensions. Much of the exterior design such as the spoilers in front of the front wheel arches, the rear spoiler or the bars below the headlights was introduced with vehicle aerodynamics in mind. Th ...

Rear-engine, Rear-wheel Drive Layout
In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive shaft with low-floor buses, this layout has become increasingly rare in passenger cars. Overview Most of the traits of the RR configuration are shared with the mid-engine rear-wheel-drive, or MR. Placing the engine near the driven rear wheels allows for a physically smaller, lighter, less complex, and more efficient drivetrain, since there is no need for a driveshaft, and the differential can be integrated with the transmission, commonly referred to as a transaxle. The front-engine front-wheel-drive layout also has this advantage. Since the engine is typically the heaviest component of the car, putting it near the rear axle usually results in more ...

Audi Q5 E-tron
The Audi Q5 e-tron is a battery electric mid-size luxury crossover SUV with three-row seating produced by Audi through the SAIC-VW joint venture in China. Based on the MEB platform, it is the fifth battery electric model in the Audi e-tron series. Closely related to the Q4 e-tron, the model is regarded as the Audi equivalent of the similarly-sized Volkswagen ID.6, and not mechanically related to the Audi Q5 or the Q8 e-tron which use the MLB platform. Overview The Q5 e-tron was revealed at the 2021 Guangzhou Auto Show as the first three-row model of the e-tron series, and the ninth model that is based on the MEB platform. While sporting a separate exterior design, dashboard design is derived from the Q4 e-tron, with a 10.25-inch digital instrument cluster and an 11.6-inch infotainment touchscreen. Two variants are offered, which are the Q5 40 e-tron and Q5 50 e-tron quattro. The Q5 40 e-tron is powered by a single motor, while the flagship Q5 50 e-tron quattro features ...

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 ...

Spoiler (car)
A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Spoilers on the front of a vehicle are often called air dams. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse. The term "spoiler" is often mistakenly used interchangeably with "wing". An automotive wing is a device whose intended design is to generate downforce as air passes around it, not simply disrupt existing airflow patterns. As such, rather than decreasing drag, automotive wings actually increase drag. Operation Since spoiler is a term describing an application, the operation of a spoiler varies depending on the particular effect it is trying to spoil. M ...

Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...

Geneva Motor Show
The Geneva International Motor Show is an annual auto show held in March in the Swiss city of Geneva. The show is hosted at the Palexpo, a convention centre located next to the Geneva Cointrin International Airport. The Salon is organised by the Organisation Internationale des Constructeurs d'Automobiles, and is considered an important major international auto show. First held in 1905, the Salon has hosted almost all major internal combustion engined models in the history of the automobile, along with benzene- and steam-powered cars from the beginning of the century. Exotic supercars often steal the spotlight during their debuts at the show. Prototypes, new equipment, technical breakthroughs, international partnerships, as well as political and social debates, have been announced at the exhibition. The show is regarded as a level playing field for the world's automakers, aided by the fact Switzerland lacks an auto industry of its own. Sections Areas of the show: #Motor cars, ...

Crossover (automobile)
A crossover, crossover SUV, or crossover utility vehicle (CUV) is a type of automobile with an increased ride height that is built on unibody chassis construction shared with passenger cars, as opposed to traditional sport utility vehicles (SUV) which are built on a body-on-frame chassis construction similar to pickup trucks. A term that originated from North America, the term crossover was initially used for any vehicle that blends characteristics between two different kinds of vehicles while, over time, crossover mostly refers to unibody-based SUVs. Crossovers are also described as "car-like SUVs" or "car-based SUVs". The term SUV is often used as an umbrella term for both crossovers and traditional SUVs due to the similarities between them. Compared to traditional SUVs, crossovers are known to be less capable of use in off-road conditions or hauling heavy loads, while instead offering other advantages such as superior fuel economy and handling.
