Engine hp rating is very important thing for car manufacturers and car owners alike. This continues to be the case despite the fact that the average car owner does not understand the implication of engine horsepower and torque or the difference between the same. Of course, it is not necessary to know these technical specifications by heart. It does not take long for the car owner to discover when the engine accelerates the fastest and when the engine continues to generate high power for the longest period of time.
Auto engines hp ratings had very humble beginnings. The Ford model T had a 20 hp engine and this was considered sufficient for the average car owner. Of course, racing cars needed higher power generation and they made use of bigger engines for the same.
During the 20's and the 30's, importance was given to improvement of efficiency of the car engine rather than increase in its size. Of course, auto engine hp continued to increase as roads became better and speeds improved.
The Second World War might have put the civilian automobile construction industry into hibernation but construction of cars, jeeps and other vehicles for the military and the war machine continued at full speed.
The benefit of research and development was seen in the 50's and the 60's when muscle cars made their entry. These cars were designed for one purpose - performance. This was achieved by increasing engine size and engine horsepower. This was a time when power generation exceeded 200 hp on a regular basis. Muscle cars still generate more power as compared to other vehicles on the road.
The late 60's and the early 70's saw engine horsepower specifications cool down. This was because the fuel crisis had begun and people realized that powerful engines consumed a lot of fuel. The average car engine operated well under 200 hp during the two decades. It was only in the mid eighties that the trend for bigger and better horsepower engines began again.
Today, cars are available in different sizes and for different purposes. Auto engine hp depends a lot on the purpose and the performance requirements of the owner. Of course, racing cars have enabled auto manufacturers to experiment to the very limits in terms of engine technology. These cars have a hp rating ranging from 800 hp to 1000 hp. Of course, the average individual, even those who love muscle cars, never need more than 300 hp engines in their automobiles.
Rather than ignoring the hp rating in the manual, one should try to understand what it means and find out how to make use of it to improve performance. If you need help, just check out World Wide Web and all its resources to understand engine performance and the role of engine hp in engine performance better. You can put this knowledge to good effect by buying good engines online as well.
