I've heared that automatic cars use up 20% more fuel than a manual. Surely you would think that an automatic car would select the most appropriate gear for the road conditions vs say, in a manual car leaving it i
No longer a hard fast rule, but they have less parts and are cheaper to produce, lighter. Also less power loss than an auto.

also most classic automatic transmissions (we're not talking fancy dsg stuff here) are not able to anticipate what the driver is going to do. So it may change gear too late, which gives higher revs, and higher revs = more fuel consuption.

i dont think i know anyone that drives an automatic car,or ever have....

I coast a lot in my manuals. A real lot. As opposed to almost always having your foot on the gas in an auto right up until you need to brake.

as vdub points out, manual transmissions generally weigh less than automatics, although this isn't always the case with higher end engines. automatic transmissions also use gas to change gear, whereas manual uses just the power of your arm. a skilled driver can usually select the right gear at the right time but the higher end automatic models can also do this quite well now.

constantly variable transmission (CVT) is supposedly more efficient but rarely seen in cars but used quite often on motorbikes.

CVT's keep the engine on the rpm where the torque is maximum, so it always runs at the highest efficiency.
But it is pretty strange to see a car accelerating without the sound of the engine changing :smashed:

1)OK, imagine revving your engine, when you change gear, being you, as a person in all your amazing glory you are in charge of the gear changes.

2)Now imagine a machine, being a machine it is not aloud to make mistakes or else no one would buy it.

3)So being that you are in control of your car and a machine is only going to change gear when the revs are at boy racer high level. Why do you think an Auto uses more fuel?


P.s. Boy racers indeed use more fuel then Auto.:teeth:

Sorry bro, its a mad way to state it, but I hope you get the jest. Love.:tea:

Manual transmissions generally offer better fuel economy than automatic torque converter transmissions; however the disparity has been somewhat offset with the introduction of locking torque converters on automatic transmissions.

Increased fuel economy with a properly operated manual transmission vehicle versus an equivalent automatic transmission vehicle can range from 5% to about 15% depending on driving conditions and style of driving.

Manual transmissions do not require active cooling and generally weigh less than comparable automatics.

The manual transmission couples the engine to the transmission with a rigid clutch instead of a torque converter which slips by nature. Manual transmissions also lack the parasitic power consumption of the automatic transmission's hydraulic pump.

Additionally, they require less maintenance and are easier to repair due to the fact that they have fewer moving parts and are, mechanically, much simpler than automatic transmissions. When properly operated by an experienced driver, manual transmissions also tend to last longer than automatic transmissions.

What's the moral? Automatic cars are here to stay. That little extra fuel consumption and maintenance cost makes up for the ease of driving abeg. Moreover modern automatics use same fuel (if not less than) manuals so what are we talking?

Are u also going to ask people not to buy full sized luxury SUV's? Because they never come with manual.

Yes ooooo

But to be honest,I have been so used to manual & enjoy its drive,if u watch my feet on the manual pedals in a sound engine,you will think I'm driving an auto,I ve even had drivers asking if my car was auto or manual as they hardly see me make use of the clutch or change gears,I think I'm very good @ driving manuals and I love them.with a manual I fear not for weak battery,transmission failure or kick starter failure,if clutch pack up @ ibadan I can still drive D car to lagos wella,meanwhile my manual cars hardly have clutch probs except I give someone else to drive

You have masters this act..my clutch has failed once that was years ago..my gears are smooth ...but how did you masters this seamless transmissions

I am interested. I am a manual buff

It's bad for the manual transmission but very possible, I have driven from kaduna-lagos without a clutch, all I had to do was switch gears in a hard to explain sequence. Got to lagos, replaced the faulty upper clutch member and car runs fine till date.

Now all I can say is that you a master


How did you do that ?


Find way to let us know bro
