One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
Brake horsepower per cubic centimeter. Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the ' state of tune ' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
or 1.6/π = 0.51 times engine displacement in cc The limits between the horsepower denominations were drawn at either 0.49, 0.50, or 0.51 in different cantons. Thus, the eight horsepower category would cover cars of about 7.5–8.5 CV. In 1973 Berne switched to a taxation system based on vehicle weight, and a few other cantons followed.
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 ...
The engine is a 2.0 litres (1,950 cc) turbo-diesel cast aluminum block, inline four-cylinder with balancing shafts. [3] It has a single turbo and its cylinder walls are lined with slippery Nanoslide, an iron-carbon coating that cuts friction. In the 200-configuration it produces 110 kW (150 PS; 148 hp) at 4,500 rpm with peak torque of 320 N⋅m ...
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a ...
The M158 is a 6.0 L (5,980 cc) version based on the M275 AMG. The engine uses smaller twin scroll type turbos (for reduced turbo-lag), a bespoke Bosch ECU, a modified intercooler configuration, and dry sump lubrication. It produces 730 PS (537 kW; 720 hp) at 5800 rpm [8] and 1,000 N⋅m (738 lb⋅ft) of torque at 2250-4500 rpm. [8]
The Honda CR-Z is a sport compact hybrid electric car manufactured by Honda and marketed as a "sport hybrid coupe." [2] The CR-Z combines a hybrid gasoline-electric powertrain with traditional sports car [3] elements, including a 2+2 seating arrangement [4] (excluding North America, where offered as a two seater) [5] and a standard 6-speed manual transmission.
