The LS7 is a V8. If you look I never compared it to the pentestar. i compared the Nissan, which goes for mid 20s in several vehicles, and the BMW, which goes for starting in the mid 20s again in many vehicles. You got ripped off if a 328 xi cost more than an overland. I have a twin turbo 335 vert which isn't much more than an overland. Sorry, but I don't see the Pentestar as this ground breaking super V6. At best it just catches up with the rest.

I know what I paid for both vehicles. Maybe your vert's a stripped down car. MW options are expensive.

I never claimed that the Pentastar was "this ground breaking super V6". What I said was that it's been on Ward's ten best list for two years now and is a better engine than the 5.7L Hemi based on its power to displacement ratio.

Re: Advice needed.. V6 or V8?

Go on thei sites for bmw and check prices. Mine has every option except NAV. As for a motor being better because it has more power per liter, etc. I don't agree. Hemi still has more power period and because it isn't stressing as much to make the power I would bet it would last longer. If you look at past 6 motors in Patriots, etc. they pretty much fried themselves by 100k. Bet the hemi is still pulling strong at 500k with proper maintainence. And each motor replacement definitely makes up some ground on any fuel savings.

Ward points out that they like the motor because it will be in everything Chrysler makes, so its versitile and that it's made from aluminum to save weight. They say they use and older version of fuel injection vs. newer technologies and they say several times its the best 6 Chrysler has made, not best 6. They also say that there are many other motors out there that make more power for the same size but because you can plug this one in a car, SUV, or minivan is why they liked it instead. Not really why I choose a motor. I'd rather choose mine for balls and longevity.

Re: Advice needed.. V6 or V8?

My wife's has nav and it's not loaded so I'm not sure how yours can be "loaded" without nav. I'm not really a BMW fan do I wouldn't know. I just know that the cost/ pound was pretty high.

HP/ liter doesn't correlate with longevity. "Balls" don't either. In fact efficiency usually does. *shrug*

The Hemi and the Pentastar will have virtually the same usable life. Any modern engine will go several hundred thousand miles with proper maintenance.

BMW options their vehicles oddly. They have packages, but they have far greater permutations of options a specific vehicle can have, and its possible to get one with everything but nav.

One other thing, Mercedes is the same way...almost none of them below a mid packaged E or 5 have leather seats. They all ship with leatherette or MB Tex. So yes, you could have a $60,000 BMW or Mercedes and have vinyl seats. Very weird.

Re: Advice needed.. V6 or V8?

It aint a real hemi. Sorry Chrysler is using false advertising. Look at combustion chamber on an old school 426 and compare to a current so called hemi

I have rebuilt BMW I6s, I4s, and V8s with numerous track days and auto x days on them or some that have race. Majority of them stock with a chip. Block typically shows no wear and the bores just need a light honing at most. You could rebuild w/o it. Cranks are fine and so are the rods. These are all engines with 300K+ miles on them and numerous trips to redlines of 7000 or more. Cylinder heads are still within spec and just get new seals, valve guides etc. These are BMWs everyday engines and not their M's. Chrysler has nothing to compare with a BMW M engine. Chrysler would have to depend on a lot of Fiat technology to compete and Fiat technical know how is scary. Remember back in mid 0's when F1 used 1500cc turbo engines. BMW used weather stressed stock I4 blocks from 2002's they found in junkyards for their F1 engines. BMW engines where the most powerful and one pegged BMWs dyno at over 1700hp. They dont know how much hp this engine had from a stock block.

Sorry Ford's 5l is a superior V8 in truck applications and so is GM's V8. Toyota's, Nissan's, BMW's and Mercedes V8s are all more modern designs, more reliable and more efficient.

Also remember old school hemis from the mid 60's on were drag racing and NASCAR engines. They never cut in Can Am or endurance racing. They just couldnt compete. Going 1320ft and running around an oval just doesnt breed a flexible and durable engine.

Re: Advice needed.. V6 or V8?

Wow...ok a little drama in here I see.

I believe V6 or V8 is personal preference and should be experienced by the person considering buying one of them. If you do not mind a little less performance then the V6 is probably the best option. It get better gas mileage and is nearly as quiet.

If you are after more performance for passing and stop light rallies then the Hemi is definitely worth a look. In my test drives the Hemi had less road noise but doesn't get the MPG of the Pentastar V6.

In the end pick what you like that works for you and live happily ever after.

Well said. And I ordered mine without the NAV cause I didn't want to spend $4,000 for a nav when I can get a garmin for $125 and do the same basic thing. Don't see the need. Still don't. Base BMW 1 or 3 series is in the mid 20s to low 30s and that's for the newly redone 3 series. Same for the Merc. Guess your wife killed you with options. Premium stereo, HIDs, NAV and you add 10k for nothing. You could do all that for 2,000 aftermarket and it would basically be the same. I got every option on mine except Satellite radio, NAV, and active steering which no body gets and with convertable, turbos, etc. it was 52k sticker.

And as for the motors, sure the pentestar will hold up for a while, but the BMW is just breaking in at 100,000 and I had the Nissan and it was like new at 165k miles. All I ever did was oil changes, brakes, and tires. Nothing else. I don't see that happening with a pentestar. You won't see it gaining HP and running more smoothly as you increase miles past 50k like a bmw.

Oh and just checked. With over 10k we have averaged 18.5 mpg with the hemi. Sure we would have done better with the Pentestar but it wouldn't have been much. Its not what you drive, but how you drive it. If I drove the pentestar to accelerate the same way I do with the hemi, it would have had similar mileage cause it would have been working harder and feeding the extra gas to keep up. A good example is how top gear did a test and had a prius go around a track as fast as possible, and a V8 BMW M3 follow it at the same speed. At the end of the test the BMW had 2mpg better mileage cause it was basically idling while the Prius was screaming the whole time and sucking down gas. It got 17 mpg vs. BMW 19. You can find the test on Youtube. So for my driving habits, the Hemi probably actually save me fuel or at least ties it. I would be stomping the V6 all day and not smiling either.
