I6 (inline) has 6 cylinders in a line and a V6 has 2 banks of 3 cylinders in a V.

Yea i kno that is just i was reading some 1 said that the i4 shouldve been a v6 or I6 but is there real differenece other than how there place in the car???

Well you can place an engine inside the engine bay several ways.

Then there's also several engine bay standards. Front-engine, mid-engine and rear-engine.

Racecars often have mid-engine setups. The engine is right behind the driver in that kind of setup.

Then there's front-engine setups (95% of cars use this). The Camry has that.

Then there's rear-engine setups where the engine is in the trunk. The front hood is your real trunk. Cars like the Porsche 911 have this.

Keep in mind that while mid-engine and rear-engine setups may seem similar, the difference is that the mid-engine setup places the engine at, or ahead of the rear axle, while the rear-engine setup can never be ahead of the rear axle.

V-shaped engines (V6, V8, V10, V12, etc) are almost always mounted front-rear. Inline-6 engines can be mounted either left-right, or front-rear. However, most are mounted front-rear. Inline-4 engines can also be mounted either way, but most are mounted left-right.

There are also 5-cylinder engines (inline). Those can be mounted like an I4. For instance, VW's new Jetta and Rabbit models have a 2.5L I5 engine as standard.

Back in the day, you could also have an inline-8 engine, but nobody makes those anymore.

Generally speaking, only RWD cars use I6's, except for maybe some much older models. BMW uses I6's for their cars, but besides them the majority of 6 cylinder cars are V6's.

We had a BMW 330i back in the day with a 3L I6. Good horsepower, but I think I6s make less torque in general compared to V6s.

Like if you compare any two similar-sized I6 and V6 engines, the V6 will always have 10-20% more torque.

What a crap statement!! More uniformed forum BS!!

Have you even driven enough Inline-6 powered cars to argue against my statement? If my statement is so "uninformed", then why not take the time to prove yours in more imformed?

Here's one fair comparison. Take BMW's current 3.0L Inline-6. It makes 230hp and 200 torque in their 328i sedan. Compare this to Mercedes' 3.0L V6 making 228hp and 221 torque in their C280 sedan. Both eat premium gas.

That's a comparsion but it has nothing to do with engineering.

Engine cylinder configuration has nothing to do with respective torque.

I agree with njerald. Your basically making an observation by comparing the bmw to mercedes. You aren't proving anything. It all depends on the design and I'm not just talking about I6 vs V6.

[Toysrme]

It's not the torque. It's the inline 6's extremely lazyness to rev compaired to a similar sized / technology packed v6.

It's more of a combination of the relative ease for an OEM to make an itnake manifold that will tune in the neighboorhood of the entire powerband, VS an i6's mid-high power dominance. And the fact that there is just so much more damned reciprocating mass, they flat out respond slower.





At any rate... You can create the same powerband on any engine if you feel like it. Yazovets you're using a gloriously incorrect blanket statement, save face; stop talking about it.

Difference would be the engine design, the engine sizing, balance, simplicity, cost as well as platform. The Volvo S80 is one engine with a FWD layout with an inline 6. It was said to be impossible for an inline 6 to be on a FWD layout due to its sizing (long and narrow) but with the use of the world's shortest tranny, Volvo was able to be successful. I6 is more simpler and would generally mean more reliable since less moving parts are better vs thier v6 counterparts. The H6 is another different story.

[wilfredcruz]

Normally an I-6 is a bit more efficient than a V6, the V-6 you could fit in more places than a I-6. In a FWD you can't really fix a I-6, I'm sure it is possible but too hard. At some point some airplanes had inline 12!!!

BUT it all comes down to design, nowadays it could go either way.

Here's a comparison much more fair than yours since it uses the same manufacturer

1995 Toyota Camry 3.0 V6
188 HP
203 lb/ft Torque

1995 Toyota Supra 3.0 I6 (no turbo)
220 HP
210 lb/ft Torque

Even that isnt a fair comparison, but fairer then what he compared them to.
