๐ Cyclecar
A cyclecar was a type of small, lightweight and inexpensive car manufactured in Europe and the United States between 1910 and the early 1920s. The purpose of cyclecars was to fill a gap in the market between the motorcycle and the car.
The demise of cyclecars was due to larger cars โ such as the Citroรซn Type C, Austin 7 and Morris Cowley โ becoming more affordable. Small, inexpensive vehicles reappeared after World War II, and were known as microcars.

๐ Mercedes-Benz W125 Rekordwagen hit 268 MPH โ in 1938
The Mercedes-Benz W125 Rekordwagen was an experimental, high-speed automobile produced in the late 1930s. The streamlined car was derived from the 1937 open-wheel race car Mercedes-Benz W125 Formel-Rennwagen, of which also a streamlined version was raced at the non-championship Avusrennen in Berlin.
The main difference to the Grand Prix race car, which had to adhere to the 750ย kg (1,653ย lb) limit, was the engine. While the GP car had the 8-cylinder inline M125, which was rather tall, the record car was fitted with a V12 engine that was lower, which reduced drag.
The car is on display in the Mercedes-Benz Museum in Stuttgart.

๐ Sinclair C5 Electric Car (1985)
The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle". It was the culmination of Sir Clive Sinclair's long-running interest in electric vehicles. Although widely described as an "electric car", Sinclair characterised it as a "vehicle, not a car".
Sinclair had become one of the UK's best-known millionaires, and earned a knighthood, on the back of the highly successful Sinclair Research range of home computers in the early 1980s. He hoped to repeat his success in the electric vehicle market, which he saw as ripe for a new approach. The C5 emerged from an earlier project to produce a small electric car called the C1. After a change in the law, prompted by lobbying from bicycle manufacturers, Sinclair developed the C5 as an electrically powered tricycle with a polypropylene body and a chassis designed by Lotus Cars. It was intended to be the first in a series of increasingly ambitious electric vehicles, but the development of the follow-up C10 and C15 models never got further than the drawing board.
On 10 January 1985, the C5 was unveiled at a glitzy launch event but it received a less than enthusiastic reception from the British media. Its sales prospects were blighted by poor reviews and safety concerns expressed by consumer and motoring organisations. The vehicle's limitations โ a short range, a maximum speed of only 15 miles per hour (24ย km/h), a battery that ran down quickly and a lack of weatherproofing โ made it impractical for most people's needs. It was marketed as an alternative to cars and bicycles, but ended up appealing to neither group of owners, and it was not available in shops until several months after its launch. Within three months of the launch, production had been slashed by 90%. Sales never picked up despite Sinclair's optimistic forecasts and production ceased entirely by August 1985. Out of 14,000 C5s made, only 5,000 were sold before its manufacturer, Sinclair Vehicles, went into receivership.
The C5 became known as "one of the great marketing bombs of postwar British industry" and a "notoriousย ... example of failure". Despite its commercial failure, the C5 went on to become a cult item for collectors. Thousands of unsold C5s were purchased by investors and sold for hugely inflated prices โ as much as ยฃ5,000, compared to the original retail value of ยฃ399. Enthusiasts have established owners' clubs and some have modified their vehicles substantially, adding monster wheels, jet engines, and high-powered electric motors to propel their C5s at speeds of up to 150 miles per hour (240ย km/h).

๐ Elon Musk's Tesla Roadster
Elon Musk's Tesla Roadster is an electric sports car that served as the dummy payload for the February 2018 Falcon Heavy test flight and became an artificial satellite of the Sun. "Starman", a mannequin dressed in a spacesuit, occupies the driver's seat. The car and rocket are products of Tesla and SpaceX, respectively, both companies founded by Elon Musk. The 2008-model Roadster was previously used by Musk for commuting to work and is the only production car in space.
The car, mounted on the rocket's second stage, acquired enough velocity to escape Earth's gravity and enter an elliptical heliocentric orbit crossing the orbit of Mars. The orbit reaches a maximum distance from the Sun at aphelion of 1.66 astronomical units (au). During the early portion of the voyage outside the Earth's atmosphere, live video was transmitted back to the mission control center and live-streamed for slightly over four hours.
Advertising analysts noted Musk's sense of brand management and use of new media for his decision to launch a Tesla into space. While some commenters voiced concern that the car contributed to space debris, others saw it as a work of art. Musk explained he wanted to inspire the public about the "possibility of something new happening in space" as part of his larger vision for spreading humanity to other planets.

๐ List of Countries by Vehicles per Capita
This article is a list of countries by the number of road motor vehicles per 1,000 inhabitants. This includes cars, vans, buses, and freight and other trucks; but excludes motorcycles and other two-wheelers.
China has the largest fleet of motor vehicles in the world in 2021, with 292 million cars, and in 2009 became the world's largest new car market as well. In 2011, a total of 80 million cars and commercial vehicles were built, led by China, with 18.4 million motor vehicles manufactured.
๐ RenaultโNissanโMitsubishi Alliance
The RenaultโNissanโMitsubishi Alliance, originally known as the RenaultโNissan Alliance, is a French-Japanese strategic alliance between the automobile manufacturers Renault (based in Boulogne-Billancourt, France), Nissan (based in Yokohama, Japan) and Mitsubishi Motors (based in Tokyo, Japan), which together sell more than 1 in 9 vehicles worldwide. Renault and Nissan are strategic partners since 1999 and have nearly 450,000 employees and control eight major brands: Renault, Nissan, Mitsubishi, Infiniti, Renault Korea, Dacia, Alpine, and Venucia. The car group sold 10.6ย million vehicles worldwide in 2017, making it the leading light vehicle manufacturing group in the world. The Alliance adopted its current name in September 2017, one year after Nissan acquired a controlling interest in Mitsubishi and subsequently made Mitsubishi an equal partner in the Alliance.
As of Decemberย 2021, the Alliance is one of the world's leading electric vehicle manufacturing groups, with global sales of over 1ย million light-duty electric vehicles since 2009. The top selling vehicles of its EV line-up are the Nissan Leaf and the Renault Zoe all-electric cars.
The strategic partnership between Renault, Nissan and Mitsubishi is not a merger or an acquisition. The three companies are joined through a cross-sharing agreement. The structure was unique in the auto industry during the 1990s consolidation trend and later served as a model for General Motors and the PSA Group, and Mitsubishi, as well as the Volkswagen Group and Suzuki, though the latter combination failed. The Alliance itself has broadened its scope substantially, forming additional partnerships with automakers including Germany's Daimler and China's Dongfeng.
Following the November 2018 arrest and imprisonment of Alliance chairman and CEO Carlos Ghosn, accompanied by his dismissal from the alliance and its components, press analysts have questioned both the stability of the Alliance's shareholding agreement and its long-term existence. These analysts also note that, because the companies' recent business strategies are interdependent, attempts to restructure the Alliance could be counter-productive for all of the members.
In January 2023, Renault and Nissan moved to restructure their alliance in order to recover from Ghosn's arrest and manage through a post-Covid economy. The primary objective was to give both companies more autonomy.
