Compressed air cars are emission free. They also do not require a connection to the electric grid. A wind turbine or other renewable energy source can directly drive an air compressor or hydraulic pump. Compressed air cars do not rely on petrol stations or an electric grid. While centralized infrastructure might not be needed, it is an option.
In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft).
The car, which was powered by two Rolls-Royce Spey jet engines that manufacture a combined 110,000 hp (82,000 kW) and 50,000 pounds (23,000 kg) of thrust, became the first vehicle to break the sound barrier on land. [31] [33] Jet-powered drag racing cars have also appeared in National Hot Rod Association (NHRA) events since the 1970s. [34]
This is a list of cars with non-standard door designs, sorted by door type.These car models use passenger door designs other than the standard design, which is hinged at the front edge of the door, and swings away from the car horizontally and towards the front of the car.
Slovak designer Professor Štefan Klein began working on flying cars in the late 1980s. Having developed the AeroMobil, he left the company to develop a new idea as the AirCar, and set up Klein Vision with colleague Anton Zajac. [2] [3] The main fuselage of the AirCar doubles as a two-seat road car with four large road wheels.

Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds.
