# Thread: Why does the mileage of bike is less than a car?

1. ## Why does the mileage of bike is less than a car?

Dear Friends;

I have a bit of confusion and need help to make it clear.
One of my colleague stated that the mileage of his 1300CC car is around 14km/l as he drives at 60km/h. I am astonished that the mileage of an 110cc bike is around 50km/l. The difference of both vehicles is as 1300/110 = 11.8. So car is almost 12times more powerful than bike. If mileage of an 110cc bike is 50km/l than the mileage of a 1300cc car should be 50/11.8 = 4.2km/l but result is not the same. Can anyone make me clear for this point?

Sorry if this is a stupid question.

Their engines don't last that long as well. Neither does other parts aka suspension etc.

3. Bro 4 wheel vehicle normally gives 8 to 10 km per ltr (1300)

Bro my father sold 1995 or 96 model cd 70 last year with no faults

And my friends CG-125 Euro II with only 9000km on odo, the clutch plates need changing. We can keep on going for days.
Lemme call my uncles and ask them what went wrong with their mode of transports, will let you know. I might as well write a book as well.

LOL. Naaaaaaaah!
The question was kind of academic and you really need a structured academic answer to help the fellow.
I was just trying to help

EXAMPLE:
How many horses a CG churns out??? Around 12BHP at the crank.
How much horses a 1.3L car churns out??? A 1.3L KIA Classic returns an impressive 16-18km/l and is rated at 60BHP...
See? CC for CC car engine is actually "WEAKER" then the CG!!! Now we're getting somewhere to the conclusion, aren't we? Read on...
If 1.3L engine was as powerful as the CG's engine, then it would be making close to 125BHP. Keep in mind that I've overlooked the fact that CG is a single cylinder and KIA is a 4 cylinder just to keep things simple for those EINSTEINS who are calling you STUPID...
Simple thing is, MORE BHP = MORE FUEL CONSUMPTION.
Second thing goes to rpms... KIA churns out all its horsepower at roughly 4,500rpm whereas on a CG you've to rev up to 9,000rpms to squeeze out all those 12 horses.
MORE RPMS = MORE BHP = MORE FUEL CONSUMPTION.
Sure, CG makes roughly twice more BHP when it comes to BHP per CC's but its also works twice as hard to squeeze all the juice (BHP)...
Hope you understand... Really Interesting question BTW. Feel free to ask any question here... The ones who are calling you stupid doesn't know the answer themselves...
One thing I liked about signode is that he compared two vehicles a 1300cc car and 110cc bike and both of which are are neither fanatic about fuel efficiency nor are focused completely on performance. Both have similar focus. FYI Corolla dishes out 84BHP whereas sprinter dishes out maybe 8 or 9 bhp...... cant find it engine specs.

However on the other hand you are comparing you very different vehicles k-four-nine the KIA classic which was the very beginner level 1300cc car with a very light body...therefore the engine was tuned to just 60BHP. Whereas on the other hand you talked about CG125....... a bike focused on performance....... 125cc benchmark Pakistan has and to what all bikes are gauged...... its 125cc engine dished out 11BHP (not 12 BHP).

Your point is not incorrect but your example is a bit exaggerating. Sprinter engine requires 13.75cc to produce 1 BHP whereas Corolla requires 15.47cc to produce 1 BHP. So you are right..... bike is producing 10% more power per cc than the car.

CG125 a performance oriented motorcycle??? You're kidding, right?
It was designed to be an economical and reliable commuter bike, period.
Secondly, about your claim that a bike produce just 10% more power per cc then a car. Show me some solid facts like I provided...
Peace.

Kindly check Atlas honda website...... CG125 is being advertised as "POWER MACHINE..... Maximum Power .......Maximum Performance"...... checkout this atlas honda link yourself: CG125 Brochure
Nobody buys cg125 for economy......... its selling proposition is its acceleration.......... PERIOD

Secondly About the per cc power statstistic are not my claim....... these are facts extracted out from the manufacturers website.
Goto indus motors website ........ its stated there that corolla 1300cc produces 84 BHP and for Sprinter I made a calculated guess about its power as nothing is stated on the website.....which I have already mentioned in the post.

After that all you have to do is divide the engine displacement with BHP is produces...... do the math..... it will come out exactly as I have mentioned. Then find the incremental percentage. Plain and pure maths....... These are facts dude.

Secondly I never stood against our post infact I proved it with factual data that a bike engine is producing more power per cc than a car engine. You just said it............ I proved it.... so chill dude....

13. Yes people buy cg for 'shashkay' not for economy. People here don't even consider cg as a economical bike they say 'Yay gari petrol buhat peeti hai' Lol

I've kept a CG for quite sometime before I bought a Chonda 78cc. I never measured the CG's fuel consumption but after I bought the Chonda I realized how much of a gas guzzler my CG was.

15. My CG Euro II gave me 28KM/l, it was 2000KM driven. Liqui Moly engine oil used. Speed was 70-80km/h and I used to accelerate quickly.
Now, my Swift gives me approx 16km/l with AC at that speed. I change gears at 2500 Rpm usually.

Riding style makes a lot of difference. Almost all CG owners go hard on their bikes..... and an interesting consumer behavior I have noticed in CG owners....is that they hardly ever complain about its poor fuel consumption......most of them never bother to measure its km per litre. CG was my first bike....... never measured the average..... as soon as I bought a Chonda...first thing I did after the breaking in period was over was to measure its mileage.

Im a madman on my chonda....manages 40kmpl...... and I drive my civic 5th gen at moderate speeds....... 9kmpl on petrol and 120km on full tank of CNG.

Thats the point nobody buys a bigger bike for fuel economy they only buy it because of its power.

Don't know if people are stupid or what when they refer to a bike as gari......lol
