Some manufacturers, including Ford and Volkswagen, even offer a 1. And the small 1. Engine size used to be the be-all-and-end-all indicator of a car's performance, but current technologies allow for increased fuel efficiency while returning better power and torque figures.
The downside of this is the loss of the unique characteristics of larger naturally aspirated engines that make them fun to drive. Can you have too much displacement? The short answer is no. The long answer is not that easy, of course. Larger displacement tends to mean bigger and heavier pistons that have to travel a farther distance.
This kills rotational inertia and will result in a lower revving, a less "spunky" or "eager" engine, which can also mean it is less responsive. Taken to an extreme, this can result in a slower engine, and over boring an engine can weaken the cylinder walls. There was an old saying in racing circles that "there's no replacement for displacement.
Advancing technologies have put modern small displacement engines in competition with older, larger displacement engines. The gears effect alot, cars weigt effects a lot. And the usable rpm range effects a lot and the driver effects a lot.
I was looking at crossovers and compact sedans, what I see tends to be in the range of around Torque and Horsepower OR Torque and Horsepower. The Dodge Challenger Hellcat has a 6. The Audi R8 has a 5.
I myself am a bit surprised at the power figures of the Audi R8, but you have to take in mind that the Audi R8 is only naturally-aspirated, meaning that it has no supercharger or turbocharger. The Dodge Challenger Hellcat, on the other hand, has a supercharger, allowing it make more horsepower and torque. The Hellcat also has more liters of displacement, allowing it to use more fuel. A car with high torque at low to middle engine speeds to RPM will produce more power in that engine speed range.
This is good for people who like their car to accelerate strongly without having to make the engine roar to get good acceleration. On the other hand, a smaller engine car even with the same peak horsepower as the high torque car, will need to brought up to high engine speed any time it needs decent acceleration.
Cars with low torque but high peak horsepower engines, need to downshift on even the slightest inclines and need to shift down 2 or more gear to pass another car. Such highly strung engines may be a fun novelty for a while for a 17 year old boy racer, but it gets old very fast.
I am old school. I have no clue as to what 2. I evaluate by 0 — 60 in how many seconds. To me a car that takes 14 seconds to do this is not fast as a matter of fact correct me if I am wrong you have to almost push it up to the top of a hill.
If a car does 0 — 60 in 8 sec it has some guts no speed demon, if you do it in 5 or under you have the need for speed. Now I am not up to date my current car is 18 years old tells you how much I love dealing with car sales people but why is there not an interpretation mandatory of dealerships that talk your language that you understand instead of talking a language you have no clue about what it is saying. Before purchasing a car, we should first keep some valuable things in our mind such as; features, engine capacity, design, performance and mileage.
But the most efficient part if engine section; we should go for efficient engine and its features which consist of turbochargers, good horsepower and many others. So that, we can get a good driving experience. Is there a simple formula for a rough educated guess? So then the question becomes how is displacement important?
