Power-to-weight ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. 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.
Internal combustion engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (piston engine), turbine blades (gas turbine), a rotor (Wankel engine), or a nozzle (jet engine).
Radial engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful.
Panther tank
The Panther tank, officially Panzerkampfwagen V Panther (abbreviated PzKpfw V) with ordnance inventory designation: Sd.Kfz. 171, is a German medium tank of World War II. It was used on the Eastern and Western Fronts from mid-1943 to the end of the war in May 1945. On 27 February 1944 it was redesignated to just PzKpfw Panther, as Hitler ordered that the Roman numeral "V" be deleted. In contemporary English-language reports it is sometimes referred to as the "Mark V".
Maybach
Maybach (ˈmaɪbax, ) is a German luxury car brand owned by and a part of Mercedes-Benz AG. The original company was founded in 1909 by Wilhelm Maybach and his son Karl Maybach, originally as a subsidiary of Luftschiffbau Zeppelin GmbH, and it was known as Luftfahrzeug-Motorenbau GmbH until 1999. In 1960, Maybach was acquired by Daimler-Benz. The name returned as a standalone ultra-luxury car brand in 2002, sharing significant components with Mercedes-Benz cars.
Luxury car
A luxury car is a car that provides above-average to high-end levels of comfort, features, and equipment. Often more expensive materials and surface finishes are used, and buyers expect better build quality. The usually higher pricing and more upscale appearance is often associated with higher social status of the users, compared to low and mid-market segment cars. The term is relative and partially subjective, reflecting both objective qualities of a car, as well as the projected and perceived of the car marque.
