I am from India, here we have Ford Ecosport. Tt has different models, out of which one model with less cc produces more power than a higher cc model (999cc and 125ps) & (1497cc 123ps). How is this possible? What are the advantages and disadvantages of less cc more power vehicles?
I am guessing that the smaller engine has a turbocharger and the larger engine doesn’t. This would fit with the smaller engine having a lower compression ratio.
The turbo compresses the air entering the engine allowing more fuel to be added. The small engine will therefore in effect have a larger capacity and will therefore be more powerful.
The smaller engine will likely have a small amount of turbo lag, whereas the larger engine will likely be more responsive at lower revs.
Insurance may be more expensive on the more “sporty” turbo engine.
After doing a bit of research, it looks like the generation 1 of the 1.0 had a supercharger and the generation 2 has a turbo charger, while the 1.5 is a normally aspirated.
how is it possible?
Turbo/ Supercharging, higher tuning, there are a lot of possibilities to make more power out of an engine.
what are the advantages & disadvantages of less cc more power vehicles
Advantages of the "smaller" engine:
- Possibly less weight.
- Better fuel efficentcy
- Less material consumed in making it (but could be offset by added turbocharger)
- More power in high revs.
- More and complicated moving parts.
- Potentially less sturdy.
- Less torque in low revs.
