How many engines could be on this list? Volvo's white block, Audi's old and new I-5, Acura 5-cyl are already mentioned. All were very good. There's Mercedes' diesel and VW's current 5-cyl as well; they're not bad either. Any others? Hard to come up with a list of best/worst.
I honestly don't think there was a bad 5 cylinder... they were all very good in their own way. Each of them have an almost legendary reputation. Even the I-5 from GM in the Colorado, I know three people with one, and they love their truck/engine combo.
Power of a four and gas mileage of a six! Oh wait
For anyone interested, there's a great writeup/history of the Audi inline 5 cylinder 20vt here:
Then there's the Fiat 5 Cylinder. You never got it, but it was available in the Bravo/Brava and later on in the Stilo (and was nothing special, a torquey engine albeit a bit thirsty); but its turbocharged variant in the Fiat Coupé will be remembered. Sounded excellent and made the car really move. Maybe not as tough as the Audi 5 cylinder engines; it still could be mildly tuned without giving problems.
And finally (?) there's the Td5, which is the 5-cylinder turbo diesel engine developed by the Rover group for use in the Land Rover Defender and Discovery models. I don't know anything about this engine other than that (reliability/performance)
"YOL∞". - Hindu cliché.
Chevy's 5 cyl vortec seems to be a pretty solid motor. Ugly as sin, but it sounds pretty damned good
How does a rotary work? This one's easy: the magic triangle spins in the peanut and then apex seals come out.
