What makes a V6 engine different from normal car engines

"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,

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.

The V6 is a normal car engine.

The rotary is something else.

@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. 

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 shit 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.

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

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

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

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

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!

Is a V6 an abnormal car engine? Lol. Come-on, wise folks knows this, I4's are shit engines, my last two cars are 6-cylinders & my next will be a V6 too, except if 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 rackets,I feel sorry for them, ignorance is not bliss!

pls can someone help me with what a knock sensonr is...what is the implication on a vehicle.cos I wanna get a car from the united states nd I was told the rx300 needs knock sensors"..... nd like how much ..it will cost if it's really a big deal to be fix

I don't think i can own any I4 car again. I want to even upgrade to V8.

Nigerians still goes with that mentality of "e dey drink fuel" in this 21st century, which is what some pple are arguing up here.

Ofcourse you should expect a thicker engine seat for a bigger and heavier engine.

Naturally a big engine fan, give me a super charged V6 in a coupe and I will be grateful for a while, give me a super-charged v8 and I will love you forever

. . . what then happens if i give you a Mercedes M275 with a twin-turbocharged and intercooled, all-aluminum, 60° V12 engine?

he will worship you as his god! LOL

Gods knows you Don't want to find out

Old thread and I'm late to the party, but I'll contribute nonetheless.
Midas02 left out the 3 cylinder found in some mini Cooper models and 5 cylinder engines in some older Audis. Yes they're available but rare.
There are also VR6 engines in some older VWs, the engine was largely developed by VW. In this type of engine, the engine block is straight like that of a straight 6 engine but the cylinders are offset from one another such that if you plot out a profile for the offset cylinders, it'll show a 15° angle instead of a 60° or 90° angle like the traditional v6 engine. This engine has a single cylinder head not two like a traditional v6 has. The advantage of this is that it's not as wide as the v6, it has the narrowness of the I4 engine while being only a little bit longer than it. This allows it to be mounted transversely in the engine bay for FWD cars so they can have a more powerful engine than the I4 engines without a lot of compromise in packaging. So basically same packaging space and proportions but bigger engine and more power. This engines are not without its own problems though. Over heating is a major problem as the combustion chambers are tightly packed and there's more cylinder in little space compared to v6 engines. Excessive fuel consumption is also another notable problems amongst others. Turbo 4 engines can now produce matching power to the VR6 so it's being dropped in favor of the turbo 4 pot.
Edit.
A lot of kazeems don't know how to set the timing on v6 engines when replacing the timing belt or chain hence the engine gets damaged with out of whack timing by smashing the valves into the piston therefore ​bending the valve and cracking the Pistons plus other damages. They also can't properly rebuild such engines as the timing will be a challenge they can't resolve which was what caused the initial damage. You'll hear them tell you not to buy v6 engine car because they know they won't be able to handle that Challenge.
I've seen this happen to someone close.
