"V6" is an acronym for an engine with six (6) cylinders configured in a V-shaped vertical arrangement over the Main crankshaft (with 3 cylinders in each bank of the engine block). All internal combustion engines are configured with certain number of cylinders, it could be 1,2,4,6,8,10 or even 12 cylinders. All of these configurations are normal and actively used in engines all over the world!. Four (4) Cylinder engines (which I am sure you are referring to as normal) are however most commonly used in cars in many parts of the world (including Nigeria) because of its balance of decent  power, economy, smoothness and reliability. It must be noted that it is possible to have a six (6) cylinder configuration without neccesarily using a "V" arrangement - as a matter of fact, until the last decade the most common arrangement of 6 cylinder engines was the Straight-Six and not the V-6. Examples of cars that used straight-six engines in the last decade include; MB 260/300E V-boot (W124 series), Nissan Laurel, BMW 325/525 (up till date), Volvo 960, Toyota Cressida and Crown (up till 1992) and most trucks including Canter, Dyna, Coaster bus , etc. Whether an engine configuration is arranged as a V-6 or a straight-six has both merits and demerits, however, I will refrain from pushing too deep into such territories here as I do not want to digress!. In automobiles today, the most commonly used configurations are 4-Cylinders, 6-Cylinders and 8-Cylinders, with a popularity in that order. The obvious advantage of having extra cylinders is to give more Power, smoother performance and durability. The disadvantage on the other hand, is that of increased gas consumption and a slightly higher cost of maintenance and purchase. I hope this helps.

Good judgement "MIdas02". But I was expecting these from 'Inspired M" or "Viperman". May be Midas02, Viperman, InspiredM are three fingers of the same hand, ha, ha, ha, grin grin grin

As explained by Midas02, the V6 offers better performance than 4 cylinders. This is why most luxurious lines Lexus, Infiniti and Acura are V6. The gas consumption is higher too.

What makes a V6 engine different from normal car engines

The V6 is a normal car engine.

The rotary is something else.

i guess midas 02 said it all,
it depends on your area of interest to comprehend the terminologies he used.

still on that, i must point out that the v technology is an advancement in the combustion engine technology which the automobiles happens to be a member,
why its preffered is because in engineering, we believe that a v stroke produces almost double the torque produced from a straight stroke, sundry issues not withstanding

in Naija here, where petrol is cheap, the only problem u may encounter with the v tech. is the issue of complexity, most road side mechanics are still finding it very difficult to dismantle and couple v tech engines,

about the consumption, a 2001 ,2.2 litre toyota camry CE option straight 4 cylinders consumes 30mpg on highways while a 3.0 v6 XLE option consumes 27mpg
@ a torque of 136hp and 194hp respectively
now considering the fact dat the later has additional 2 cylinders more than the former, and also a larger cylinder volume.(3.0 as against 2.2)
now dont u see the v6 being more economical than the straight engine in the sense dat its only a diff of 3mpg.

to correct some anomalies here, the v6 was developed for the following reasons

1 for a higher peformance(ie full compression)

2 for a low consumption

3 to save engine space

@jp, you seem to be confusing some terms.

the V6 delivers 27mpg (miles per gallon), and the 4 cylinder delivers 30mpg which means that the 4 cyl will take you longer distance than the V6 with the same quantity of fuel. You were interpreting it as if those were consumptions. There is no way 194hp would consume less than a 136hp (excluding load factors).

I am not an auto expert but I am sure of the above.  grin wink

V6 is more smoother and has more power than a 4 cylinder considering the 4 cylinder does not use force induction, V6 consumes more gas than a 4cylinder. U got 2 extra mouths to feed in a V6, Inline 6 are more smoother than V6 but reqires a longer engine bay.

@ Kashif





the English was well articulated;
the rationale between the 4 cyl and the v6 is what i am tryin to explain, i aint confusing poo unless you dont understand,

look @ it this way (Though mathematically speaking);

4 is 66% of 6, if you agree, then you expect a six to cover just 33% of what the four will cover (in direct terms) but from what you saw above, 27 is 87%  of 30,

so it is far more economical in direct terms
if you are still confused, a mercedes 300e straight six cylinders consumes double of what a v6 of the same product will consume if you compare both in tandem.

so in practical terms, you cannot just begin to compare a four and a six cylinders of course 194hp consumes more dan a 136hp no doubt but with the V technology, the diff is negligible.

so 6v is mathching with a straight 4, thats' where the economy lies.
Re: What Makes A V6 Engine Different From Normal Car Engines by Kashif(m): 6:47pm On Aug 14, 2008
In simple terms:

V6 will take you 27 miles for every gallon of fuel (highway)
4cyl will take you 30 miles for every gallon of fuel (highway)

It is as simple as that. Your mathematical representation simply tries to prove that V6 will get you there faster with a little trade off on fuel. Sure, you should not expect fuel consumption of V6 to be 1.5 of 4cyl simply because it has two extra cylinders. Because of the increased power it delivers; it makes up for that (if you consider its torque).

We are looking at the bottom line friend. 27mpg VS 30mpg grin

Re: What Makes A V6 Engine Different From Normal Car Engines by icemann: 6:54pm On Aug 25, 2008
a straight 4 is more smoother running than a V6
when 2 pistons are up, the other two down balance the weights and reactions of the other pistons, in a straight 4
but in a V6, cause of the odd cylinder arrangement, it suffers vibrations
to check the rocking of the engine, counter weights and variations of the V angle has being used by Engine makers
Re: What Makes A V6 Engine Different From Normal Car Engines by sultaan(m): 7:07pm On Aug 25, 2008
Less work, which is why you may get to 70mph@2500rpm with a V6 but it will take around 3200rpm to maintain the same speed in the I4.Less rpm less vibration

u said less rpm less vibration?
odd piston arrangement gives more vibration
Loook at the engine seat of any v6, compare it to a l4(like a honda accord ex an a V6 of the same year)
u will notice the V6 seats are thicker copared to the l4
Re: What Makes A V6 Engine Different From Normal Car Engines by sultaan(m): 7:56pm On Aug 25, 2008
Since you'll probably pay more for luxury package you should get more in cushion comfort, anyway engine vibration shouldn't be felt if motor mounts are in good condition>smoother hsould be in terms of ease of acceleration. If you look at new er engines, you'll see that the compressor and alternator has been move to center of engine to reduce vibraton i.e 1995 cars to 2004
Re: What Makes A V6 Engine Different From Normal Car Engines by Siena(m): 8:02pm On Aug 25, 2008
Don't be deceived - a V6 may have odd piston arrangement, as opposed to an I4.
But, the V6 is always going to be smoother, harmonic distortion is less.

A V6 motor is more forgiving than an I4, in terms of balancing.
A slightly off-balance clutch / flywheel assembly will be less apparent on a V6, virtually undriveable on an I4.

With stricter rules on automobile company their is no much difference between a V6 engine and a 4 cylinder engine expect from its more economical to buy a 4 cylinder engine because its cheaper to maintain than V6.

The fuel consumption ratio can not be used as a solid point in any argument again because V6 engine now competes with 4 cylinder on fuel economy ratio due to hard works automobile company has put in to make their powerful and effective V6 engine meet the standard laid down by the regulatory body guiding them.

My V6 does 120Km/h @ 2100rpm. Now tell me that isn't fantastic! no noise, no vibrations nothing! The engine hasn't even started working sef...i hate I4s!
Re: What Makes A V6 Engine Different From Normal Car Engines by Jagermeister(m): 5:52pm On Oct 23, 2013
Come-on wiser folks knows dis,I4's are poo engines,my last two cars are 6-cylinders & my next will be a V6 too,except God blesses me some more then I'll buy a V8 SUV...Nigerians obviously have a lot of stuff going on in their heads about V6,I feel sorry for them,ignorance is not bliss!
