Real world mpg between v6 and v8 w209 MB ?

[dogorman7]

My car buddy said don’t get a 4 banger because of how much of a slouch it is in the older models.

He has a old 95 with the 3.2 and he says it gets good mpg and doesn’t slouch

I’m looking at the 03-06 mainly , the 209w with the facelift

I want something nice to daily but really not trying to flex with a old ass Benz , srs brahs

my truck gets like 8-10mpg no matter how I drive so it’s time for a 2nd vehicle to daily

On the Benz forums people say there’s a very marginal difference in MPG between the 3.2 v6 and 5.0 v8

I’d consider a 5.5 v8 in the 550 too but supposedly the transmission isn’t as stout as the older one in the previous platform and sometimes can have sensor issues

I can fix that myself as it’s nothing major but rather not have more problems than I have to

Anyway can’t decide between a v6 sedan or v8 coupe

Anyone ever own a MB v8 or v6 from that era at all ?

Is there a night and day difference in gas mileage ? I thought v6s where bad on gas before all that eco **** started coming out in the last 9 or so years

Not much difference but there is in power. I'm not just talking about peak power but overall power. MPG about the same with the same driving behavior.

V8 or nothing (srs)

I'd get a CLS550 (twin turbo V8), or a C63 (naturally aspirated V8)

Don’t think maintaince will be fun on a TT ….. anyway idk

It’s a very hard choice because I’m in love with BMWs I6 motors too , much more cars with black on black by them too

Guess I’ll have to drive some from local ads and decide if buying a car that constantly needs entire new cooling systems every year or two is worth it over the MB

I’ve been eying e46 330i coupes and e92 328i coupes

MPG is based on the driver not the cars ratings.

I drive a 700 HP M5 and I average just under 15mpg, it goes up to 22 for long highway drives.

Had a V6 camary for a rental and best I could get with it was 24 MPG highway and 20 city.

Unless you drive like grandma with a feather foot and have hundreds of miles to drive a day MPG is a stupid thing to care about.

Maybe. I'd research the specific engine and car model you are interested in. Twin turbo V8s generally aren't the most reliable engine, but certain ones are better than others (I've heard that CLS550 isn't too bad in terms of maintenance... at least relative to other twin turbo V8s). Obviously a good N/A V8 is going to beat almost any twin turbo V8 in terms of reliability, though (so maybe get the 6.3L if you want a german N/A V8, or just get a truck with a N/A V8 if long-term financial potential is what you're after)

To your other point, a BMW I6 is generally going to be easier to maintain than any twin turbo V8. I can't speak for the N/A I6 in the older BMWs (from what I hear, they are pretty solid, but yeah you will constantly be replacing rubber/plastic bits in the engine bay... like the cooling system). I did have a 2014 435i with the turbo I6 N55 engine and loved it (and didn't have any issues in the 3 years I owned the car, but the next owner did get several thousands in repairs shortly after I sold it lul).

But yeah, its a trade off between reliability and fun. Fun engines (twin turbo V8s) usually aren't that reliable (although anecdotally, the supercharged V8s in American cars like the C7 Z06 seem to be decent, unless that is just my American bias), and reliable engines (N/A V8 or I6) generally aren't that powerful (maybe 10+ years ago, but 400-500 HP with a N/A powerband which doesn't have a flat torque curve simply doesn't feel like an abundance of power these days) BUT a N/A V8 is fun to cruise around in still.

I agree with this. Fuel economy is such a small part of the overall cost of ownership associated with a car... your car's depreciation is so much more expensive than the fuel it consumes (depreciation isn't a cash expense so it doesn't seem like it, but it is more expensive than anything associated with your car). Plot out all of the costs of ownership associated with your car and you'll realize that analyzing something like fuel economy makes next to no difference in the economics of your car-purchasing decision... maybe for somebody who is VERY concerned about fuel economy (for whatever reason), but if you're asking a question anywhere close to "V8 engine", that probably isn't you (srs)

That BMW M5 with the 4.4L TT V8 is one of my favorite cars btw, especially for the money (the ~2014 ones especially)
