Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by ...
Fastest acceleration of an electric car, 0 to 100 km/h in 1.461 seconds by university students at the University of Stuttgart. [69] Electric Land Speed Record 353 mph (568 km/h). [70] Electric Car Distance Record 1,725 miles (2,776 km) in 24 hours by Bjørn Nyland. [71] Greatest distance by electric vehicle, single charge 999.5 miles (1,608.5 km).
Motor velocity constant, back EMF constant. is the motor velocity, or motor speed, [2] constant (not to be confused with kV, the symbol for kilovolt), measured in revolutions per minute (RPM) per volt or radians per volt second, rad/V·s: [3] The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM ...
A kinetic energy recovery system (KERS) is an automotive system for recovering a moving vehicle 's kinetic energy under braking. The recovered energy is stored in a reservoir (for example a flywheel or high voltage batteries) for later use under acceleration. Examples include complex high end systems such as the Zytek, Flybrid, [1] Torotrak [2 ...
Dynamometer. A chassis dynamometer. A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
In automobile engineering, electric vehicle conversion is the replacement of a car's combustion engine and connected components with an electric motor and batteries, to create a battery electric vehicle (BEV). There are two main aims for converting an internal combustion engine vehicle (aka combustion vehicle) to run as a battery-electric ...
Formula E cars are the fastest regulated electric road-course racing cars in the world. [7] Major changes made for the 2022–23 season in the development of the Gen3 car were delivered as software updates directly to the advanced operating system built into the car. [8] The estimated top speed is 322 km/h (200 mph).
During the early years of the motor car, each country developed its own system of road signs. ... Conversions between common units of speed; m/s km/h mph (mi/h) knot ...
