Re: Three cylinders.

When we were planning to buy a new car earlier this year we had a look at VW Golfs. The smallest engine is 1.0 litre 3-cylinder, which has some excellent reviews. However, I somehow couldn't bring myself to like the idea so we went for the 1.6 litre 4-cylinder.

According to all the reviews I've seen, the 3-cylinder engine is perfectly smooth, although I don't understand why it is not possible to make a 1.0 litre engine with 4 cylinders.

What advantage would a 3-cylinder have over a 4-cylinder of the same capacity?

Well that makes sense.

I suppose it also saves money on buying spark plugs!

Re: Three cylinders.

All to do with ever decreasing emissions , losing a cylinder lowers the emissions and car manufacturers can meet their targets, adding a turbo increases the power and makes a smaller engine behave like a much bigger one

I can certainly appreciate the advantages of turbochargers, but whether three- or four-cylinder, I cannot see any difference in emissions if the total capacity is the same.

Which was why I was asking about the life of a 3 cylinder engine,surely its going to be working harder.

Well if it’s looked after, ie regular oil changes, not thrashed etc there’s no reason why it shouldn’t last

Re: Three cylinders.

I came across this. I like the quotes...

"...which is why they’re popular in cars designed for men who have had their wedding vegetables removed surgically, often by an ex-wife with a rusty teaspoon. "

and

"Which is why their natural habitat is the cheap, shitty econobox. Putting a three-cylinder engine in a car is a decision only an accountant could ever ratify. "

I can't say I know much about three v four cylinders but I just wanted to say that living in Devon (as I do), there are some mighty hills around. Even my mighty old 2ltr anti social beast struggles on some of the hills. So I'm wondering if having just three cylinders would reduce torque?
