I've had a Triumph Daytona 675 and now a street triple r and both of them sound way better than any inline 4. So it's no surprise.

Wow!
A F20 with that 3 cylinder would make an excellent first car, wouldn't it?

Of course it has. Nowadays it's easy to adjust engine sound, just upload a new soundtrack and that's it. You can also play sound from S85/S65 using iPod and imagine what you want. Work with older cars too!

[bumere90]

exhaust is wiggling

It's great opportunity for my country's tax policy for under 1600 cc engines. That's my point.

I don't understand why they don't improve the 1.2L 1.4L 4 cylinder engines and make them strong/robust/fuel/co2 friendly. Why the 3cyl?

The advantage of the 3 cyl engine over a 4 cyl engine is less frictional losses, meaning less fuel is burned just to make the engine turn over (which is why we now have the 4cyl N20 engine instead of the 6 cyl engines).

A 3 cyl engine has 25% less cylinders than a 4 cyl. If 4 cyl is 100% and each piston/cyl equates to 25% frictional losses, then you loose 25% of that frictional loss from the pistons by downgrading to a 3 cyl.

You also have one less pair of valves to operate. Lighter engine, manifolds etc, which all cotributes to a more fuel efficient vehicle.

Downside could be vibration issues because of the low number of combustion cycles per crank rev.

I guess the nice sound has to do with the frequency of combustions which gives it a nicer sound than a 4 cyl. It's kinda similar to a 5 cyl engine, which also has a odd syl. count.

Three banger sounds healthy

[phillye30fanboy]

damn. doesnt look that slow either....

[Dino355]

Loving it! I'd rather have that than a 4 cylinder diesel....

And they are modern engines. The old BSA Rocket 3/Triumph Trident 3 cyl's sounded much better.

And then of course there was the greatest 3 cyl of them all.

MV's 3 cyl GP500

The best ever rider on the best ever GP bike

Wow, a mini F8x M(ag) engine! Lol

It's funny to think that a BMW automobile's engine is comparable to a SeaDoo...

[mot]

Very nice. What will this motor go into?

[positiveions]

good climbing power from 4k rpm all the way to redline. Doesn't sound bad.

[turbotoy4me]

Sounds real nice, Good job.

[EdM5]

Pretty impressive

[kwike92]

Wow sounds great!

[dreamspeed]

Not bad, actually has a deep gurggle reminiscent of something with a lot more cylinders

[to_riffic]

I wonder if this'll make it into the MINI. I wish it sounded like this! So much deeper...

[grimlock]

Something about the N20 /V8s sounded annoying at high revs. Could only mask it with an exhaust, then that's all you hear.
This doesn't. The exhaust MATCHES the engine. Very sporty and lots of fun in a small car. And you don't even think that it has a turbo.
How can the 4/8 cylinder's survive now that there is a choice?
Will the new M3 I6 multi turbo engine replace alot of V8TT functions?

[d3l0n]

wow... not bad at all. BMW always knows how to get a lot out of an NA engine. Once I saw them doing forced induction, I knew they'd excel.

[cvandenhaute]

I wish the new 328i sound that good!
