Thanks, that was interesting. Two of my favorites made it: Porsche and BMW, but I think the WRX engine will make it later.

Sorry but wards doesn't know an engine from a pile of dung.

They had the nissan V6 on the list when it made less power than the Ford 3.8L, alot less torque, and in general was inferior. Nice as the Nissan V6 is much more expensive to make.

Thier claims on the S2000 motor are utter rot, as there are hundreds of motors that beat it in HP/L, like say almost any modern motorcycle engine. The Caterham 7 has a version with a motorcycle engine that puts out a heck of alot more HP/L than the S2000. Never mind that HP/L is a truely worthless way to measure an engine.

In short wards picks 10 engines then justifies its picks, insted of truely looking at what makes an engine great.

I think it is aiming on engines which one can buy easily. For the S2000 case, it is a mass produced engine which makes that much hp without any force induction and has good reliability rating.
What a bitter bitter man u are xt6wagon. Take a chill pill. hehehehe....
But I do sort of understand what u're trying to convey. I mean, why not an F1 engine? or even the McLaren F1 engine. That's a beast. But if u notice those engines mentioned are "regular consumer" engines.

Yes, if you can't see your way past big-capacity, E-Z-Power gas-guzzling V8s. Tell that to Paul Rosche (BMW) and Honda.

What is the more remarkable? A 5.7l V8 producing 321 bhp or a 3.2l six producing the same power with 50% better fuel economy and a wider power band? Sure, the smaller engine will have less torque, but that is why we have gearboxes, no?

you said it yourself in that statement how important engine capacity vs horsepower ratio are.

But i can see his argument. If you throw in a limitation on production costs then from an engineering standpoint its not that great an engine... from a marketing standpoint it is.

gold is a great conductor; we use copper in telephony cuz its cheaper. does that make copper better than gold as a conductor

Also to add (i am reading it now but i dont have time now) he says the audi 1.8T has a nice power band with a light pressure turbo. a friend of mine owns a chipped audi and that thing (even when it was stock) does NOT start moving til the mid band.

Maybe that is why i like the *truck* motor we have in the stock form. lemme add my own turbo and keep it pullin'

Every engine on that list could be had for under $50K... limits your choices to real world, real budget engines. No ultra-tech engineering, no hi-buck tricks... just soild engineering the average Joe can benefit from. I don't quite agree with the Ford OHC truck motor... I don't think a brute truck motor should have an OHC and the forced induction motor in the Lightning is cheating, anyone can do that to make power. I am disappointed that the LS6 pushrod motor from the Z06 Corvette didn't make it. I know it is old tech... but despite that, it undeniably makes power. Otherwise I think the list was well put together. I don't know much about the Asian import 6's... but I do know the V-TEC Honda and German motors deserve every bit of respect.

If you look at the bottom, those were the only engines they considered.

They seem to test the car in which the motor's happen to reside. So if the motor's great but the car sucks????

I am fairly sure they NEVER look at how much the motor costs as a factor. After all the 50K is the limit on the price of the car the motor comes in.

Next up I ask you what makes a engine a "TOP 10" I can bet you that you can compile a list of 10 best engines, and that you can find a mainstream application that those motors don't cover. How about a $10,000 light pickup? The motor needs to have a lot of torque, be simple, cheap, and ultra relaible. the Audi 1.8T almost makes it, but the cheap part. The addition of a Turbo system is somewhere around a minimum of $500 more in parts costs, much less engineering costs. I would be suprised if the Ford 2.3/2.5L SOHC costs much over $500 a long block to make.

The Ford 302 with Al heads is as light as a Honda V6, can easly be made to have more power, and is very compact. I can still run down to a ford dealer and BUY the sucker NEW, so don't give me the out of production line. The 351 is slightly heavier, but its huge natural torque production thanks to its greater stroke, makes it a wonderful truck motor.

The Ford 4.6L DOHC is used in more small car company lines than any other from what I can see. The Quvale mangusta, the Panoz esperate, and the AIV roadster, and many others. This motor is not cheap, and is slightly torqueless. It is one of the toughest motors around, and very europian in character.

The Subaru EJ-XX here is a motor that is everything from a sub 100HP lump in a econobox, to a 280HP twin turbo. Simple, very lightwieght, and moderately durable. Its a flexible lineup, with very high parts commonality. Capible of very high RPM usage due to a proper R/S ratio in most versions, and a short stroke in all versions. The latest heads are amoung the highest flowing in a stock motor. Problems include a not so good fuel rail design that runs #3 a bit leaner than the other 3 pistons, and the engines with a center thrust bearing are more prone to failure.

I could go on, but almost every engine I KNOW, has its good points and its bad points. More importanly they tend to be unique, and you can;t find a motor that is a exact replacement off the shelf anywhere. Even the old crappy Ford 3.0l vulcan V6 is unique and better at some things than any other motor. Since that is true how can you pick 10!! motors out of the hundreds out there? Only by doing a very narrow defition of what the motors used for (ie 10 best motors for economy cars under $12,000 and 2,500lbs total wieght)
