The Colomban Cri-Cri, also spelled Cricri, is the smallest twin-engined manned aircraft in the world, designed in the early 1970s by French aeronautical engineer Michel Colomban.
The aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but never widely adopted beyond this. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s.
The Diamond DA50 is a five-place, single-engine, composite aircraft designed and built by Diamond Aircraft Industries. First shown in 2006, it made its maiden flight on 4 April 2007. The project has been proposed to be powered by several different engines, but was certified on 9 September 2020 with the Continental CD-300 diesel.

The Electric Aircraft Corporation ElectraFlyer-X is an American kit and light-sport electric aircraft, designed by Randall Fishman and at one time under development by his company Electric Aircraft Corporation of Cliffside Park, New Jersey. The ElectraFlyer-X was introduced at AirVenture in 2009. The aircraft is intended to be supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.
The AeroMobil s.r.o. AeroMobil is a prototype roadable aircraft, designed by Štefan Klein and first flown in 2013. The aircraft will be produced by Slovak company AeroMobil s.r.o.
The Airbus E-Fan is a prototype two-seater electric aircraft that was under development by Airbus. It was flown in front of the world press at the Farnborough Airshow in the United Kingdom in July 2014. The target market was intended to be pilot training, but production of the aircraft was cancelled in April 2017.
The Mooney M10T is a light aircraft that was under development by Mooney Aircraft with an original proposed delivery date in 2017. The project was cancelled in April 2017.
The Bye Aerospace eFlyer 2 is a light electric aircraft designed and under development by Bye Aerospace of Denver, Colorado.
The Eviation Alice is a projected electric aircraft designed to accommodate nine passengers and two crew. Currently under development, its construction incorporates 95% composite material, is powered by two electric motors, and has a T-tail.
The Volocopter 2X is a German two-seat, optionally-piloted, multirotor electric helicopter. The personal air vehicle was designed and produced by Volocopter GmbH of Bruchsal, and first introduced at the AERO Friedrichshafen airshow in 2017. The aircraft is sold complete and ready-to-fly.

The VoltAero Cassio is a family of hybrid electric aircraft being developed by startup company VoltAero. The company plans to produce three configurations of the Cassio aircraft: the four-place Cassio 330, the six-place Cassio 480, and the ten-place Cassio 600.
A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032.
The Ampaire Electric EEL is a hybrid electric aircraft developed by U.S. startup Ampaire, established in Hawthorne, California. The forward piston engine of a Cessna 337 Skymaster is replaced by an electric motor powered by a battery, in a parallel hybrid configuration. The demonstrator first flew on 6 June 2019.
