Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year.
Engine power is the power that an engine can develop. It can be expressed in power units, most commonly kilowatt, metric horsepower (often abbreviated PS), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ...
The summary chart includes the five largest worldwide automotive manufacturing groups as of 2017 by number of vehicles produced. Those same groups held the top 5 positions 2007 to 2019; Hyundai Motor Group had a lower rank until it took the fifth spot in 2007 from the at that time split German-American auto manufacturer DaimlerChrysler, while Ford became surpassed by Honda in 2020, and even ...
However, cars registered before this date are taxed based on engine displacement. Cars under 1549 cm 3 qualify for a lower tax rate. [3] In Japan, the engine displacement is one of the factors (along with overall vehicle size and power output) used to determine the vehicle size class and therefore the cost of road tax for the vehicle.
Power-to-weight ratios for vehicles are usually calculated using curb weight (for cars) or wet weight (for motorcycles), that is, excluding weight of the driver and any cargo. This could be slightly misleading, especially with regard to motorcycles, where the driver might weigh 1/3 to 1/2 as much as the vehicle itself.
The tax horsepower or taxable horsepower was an early system by which taxation rates for automobiles were reckoned in some European countries such as Britain, Belgium, Germany, France and Italy; some US states like Illinois charged license plate purchase and renewal fees for passenger automobiles based on taxable horsepower.
Automotive superlatives include attributes such as the smallest, largest, fastest, lightest, best-selling, and so on.. This list (except for the firsts section) is limited to automobiles built after World War II, and lists superlatives for earlier vehicles separately.
