Modern vehicles run most accessories on electrical power. Typically, only 2% of a vehicle's total power output has gone towards powering accessories. [1] Electrical and hybrid vehicles may use a larger proportion of energy for accessories, due to reduced inefficiencies in the drive train, especially the elimination of engine idling.
The whole of the top of the car is covered in solar panels, and the rear slopes down to create a teardrop shape to reduce air resistance. The car weighs only 388 kilograms (855 lb) thanks to being constructed largely out of carbon-fiber , reinforced by welded aluminium tubing.
A boattail can greatly reduce a vehicle's total drag. Boattails create a teardrop shape that will give the vehicle a more streamlined profile, reducing the occurrence of drag inducing flow separation. [17] A kammback is a truncated boattail. It is created as an extension of the rear of the vehicle, moving the rear backward at a slight angle ...
In 1905, the Electric Railway Test Commission started a series of test runs to develop a carbody design that would reduce wind resistance at high speeds. Vestibule sections of different shapes were suspended independent of the carbody, with a dynamometer to measure the resistance of each.
Integrating more functionality within the vehicle's main ECUs and increasing the intelligence of its satellite nodes (i.e. modules in doors or electric motors) can help reduce the number of ECUs ...
A Swiss project, called "Solartaxi", circumnavigated the world. This was the first time in history an electric vehicle (not self sufficient solar vehicle) had gone around the world, covering 50000 km in 18 months and crossing 40 countries. It was a road-worthy electric vehicle hauling a trailer with solar panels, carrying a 6 m 2 sized solar array.
Automotive engineering, along with aerospace engineering and naval architecture, is a branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software, and safety engineering as applied to the design, manufacture and operation of motorcycles, automobiles, and trucks and their respective engineering subsystems.
Automakers would need to meet a new test simulating a head-to-hood impact and reduce the risks of serious-to-fatal head injuries in impacts at vehicle speeds of up to 25 mph (40 km/h), which ...
