Emerging car technologies

Although intensive development of conventional battery electric vehicles is continuing into the 2020s, other car propulsion technologies that are under development include wireless charging, hydrogen cars, and hydrogen/electric hybrids.Research into alternative forms of power includes using ammonia instead of hydrogen in fuel cells.

New materials which may replace steel car bodies include aluminium,fiberglass, carbon fiber, biocomposites, and carbon nanotubes. Telematics technology is allowing more and more people to share cars, on a pay-as-you-go basis, through car share and carpool schemes. Communication is also evolving due to connected car systems. Open-source cars are not widespread.

Autonomous car



Fully autonomous vehicles, also known as driverless cars, already exist as robotaxis but have a long way to go before they are in general use.


Car sharing

Car-share arrangements and carpooling are also increasingly popular, in the US and Europe. For example, in the US, some car-sharing services have experienced double-digit growth in revenue and membership growth between 2006 and 2007. Services like car sharing offer residents to "share" a vehicle rather than own a car in already congested neighbourhoods.

  Ford Mustang (first generation) The first-generation  Ford Mustang  was manufactured by Ford from March 1964 until 1973. The introduction of the Mustang created a new class of automobiles known as pony cars. The Mustang's styling, with its long hood and short deck, proved wildly popular and inspired a host of competition. It was introduced on April 17, 1964, as a hardtop and convertible, with the fastback version following in August 1964. Upon introduction, the Mustang, sharing its platform with the Falcon, was slotted into the compact car segment. The first-generation Mustangs grew in overall dimensions and engine power with each revision. The 1971 model featured a drastic redesign. After an initial surge, sales steadily declined, and Ford began working on a new generation Mustang. With the onset of the 1973 oil crisis, Ford was prepared, having already designed the smaller Mustang II for the 1974 model year. ...

 Cars Generation R211 (New York City Subway car) The  R211  is a class of New Technology Train (NTT) subway cars built for the New York City Transit Authority. Being built by Kawasaki Railcar Manufacturing for the B Division of the New York City Subway and for the Staten Island Railway (SIR), they will replace two aging subway car models: all R44 cars on the SIR, plus all R46 and some R68 subway cars. The order is split into three parts:  R211A  and  R211T  cars for the subway and  R211S  cars for the SIR. The R211Ts employ open gangways between cars, allowing passengers to see and walk through the entire length of the train – a feature not present on the subway's other rolling stock. Planning for the R211 order started in 2011. The design process started in 2012, at which time the order was supposed to consist of 75-foot-long (23 m) cars....

  Mass production Propulsion and fuels Fossil fuels Most cars in use in the early 2020s run on petrol burnt in an internal combustion engine (ICE). Some cities ban older more polluting petrol-driven cars and some countries plan to ban sales in future. However, some environmental groups say this phase-out of fossil fuel vehicles must be brought forwards to limit climate change. Production of petrol-fuelled cars peaked in 2017. Other hydrocarbon fossil fuels also burnt by deflagration (rather than detonation) in ICE cars include diesel, autogas, and CNG. Removal of fossil fuel subsidies, concerns about oil dependence, tightening environmental laws and restrictions on greenhouse gas emissions are propelling work on alternative power systems for cars. This includes hybrid vehicles, plug-in electric vehicles and hydrogen vehicles. Out of all cars sold in 2021, nine per cent...
