Why do American cars have big engines but low power?
American engines generally have lower compression ratios than their foreign counterparts. Increasing compression ratio is awesome, because it increases both horsepower and efficiency, as you may remember from our fuel octane article.
What’s the point of a bigger engine?
As a larger engine is usually able to burn more fuel and produce more power, a car with a larger, more powerful engine is likely to be able to accelerate faster and tow heavier loads than a car with a smaller engine can manage. This rule of thumb is less accurate today than in the past.
Why do so many Americans drive SUVs?
The reality is that Americans have good reasons to prefer SUVs over cars, and GM, Ford, and Chrysler are simply responding to market demand. … Again, because the vehicles are taller, drivers can see further down the road, plus they can often see over the tops of many cars.
Why do European cars have such small engines?
european engines tend to be more efficient and get more power out of smaller volumes.
Is a 1 Litre car any good?
You’ll get a good fuel economy out of them, as the smaller capacity means less fuel is used. This is great if you mainly do a lot of stop/start driving, such as in a city where there are lots of traffic lights, or if you usually make short journeys.
Do bigger engines last longer?
Larger engines will generate more torque. That allows the use of a transmission that lets the engine run slower for the same given car speed. So while a four-cylinder engine might turn at 2,500 rpm at 65 mph, an eight-cylinder engine might turn at 1,800. That could contribute to longer life.
What is a good engine size?
The optimal engine size depends on what kind of usage the car will see. Small engine cars (1L – 1.9L) tend to be the most economical and are typically best for city driving, while vehicles with large or turbocharged engines burn more fuel whilst boast higher specifications.
