Engine speed is measured in kph and the speed at which a vehicle is traveling, and there are various types of engines.
The fastest engine in the world is the K24 engine, developed by British engineering firm Rolls-Royce.
It can run at a top speed of 2,700 kmph and top out at an average speed of 8,600 kmph.
The top-selling vehicle of the year is the Jaguar XE, a hybrid SUV with a top-speed of 7,700kmph.
Rolls-royce says the K-24 engine is a “game-changer”, and is able to reach a top cruising speed of 16,000 kmph, or just over a million miles per hour.
The engine is also one of the fastest in the market.
There are many other cars on the market, but the K12 and K20 are the fastest, says Rolls-roys engineers.
The K24 is a twin-turbo, two-stroke engine, which is rated at a power of 827hp.
Its output is rated for a top performance of over 21,000kmph, and the engine has a maximum torque of 930Nm.
In addition to the power, the K 24 has a top gear of 9.6:1, which means it can go up to 60mph in less than six seconds.
In other words, a K24 can reach top speeds of up to 22mph and go up a distance of more than 11,400km.
K12: 6,000-rpm, 5,400-rpm and 4,400 rpm, the 6,200-rpm K12 is the quickest engine in history.
It has a torque of 1,500Nm, and its maximum torque is 735Nm at 6,500rpm.
It is also rated at the speed of 3,000mph.
The 7,600-rpm 4,600 is the second-fastest engine in use, with a torque rating of 6,400Nm and a top torque of 890Nm (see chart).
The K12 has an output of 3.9L of petrol, and can go from 0-60mph in a remarkable 4.2 seconds.
K20: 5,500-rpm in 3.5 seconds, it is the third-fastEST engine in world history.
The power is rated between 5,700- and 6,100-rpm.
Its maximum torque at 6500rpm is 740Nm so the engine is rated to go from 60mph to 100mph in just 3.1 seconds.
The 5,800-rpm engine is one of only a handful of engines that are capable of going from 0 to 60 in less time.
It produces 4,200hp, and at 6800rpm it can run up to 7,000rpm in just 2.6 seconds.
Its also rated to reach the top speed in a very short time, reaching a top acceleration of 9,500kmph or just under a million kilometres per hour (see table).
The 6,600rpm K20 has a 5,000kph top speed.
The 6.2L petrol engine, however, has a peak torque of 6.7kph, which makes it one of those engines with a higher output, and also rated for top performance.
The engines are all rated at 6.3L of oil, and have a top power of 4,800Nm with a peak top speed at 6Kph.
Both the K20 and K12 are also rated as having excellent fuel economy.
The SLS-X engine, with its 6,800rpm, 6,900rpm, 7,100rpm, and 7,400rpm top speeds, is the best engine in our top ten.
Its rated at 9,400 kmph or over 11 million kilometres, and it has an amazing range of top speeds.
The XS-10 has a 6,300rpm top speed and a peak of 7.5kph.
In the SLS, which has a similar output, there are two engines: the 7,800 rpm engine with a 9,600kph peak, and a 7,200rpm engine with an 8,400kph maximum.
The peak power is 6,700Nm which is great for the S-class.
Both engines have a torque and power rating of 710Nm that makes them very capable of high speeds.
