Yes yes. You win the human dictionary award on the Internet today.

OHV is commonly used to refer to pushrod OHV engines and DOHC or SOHC is commonly used to refer to overhead cam OHV engines

The car is for old retired ppl to take their wives to bfast in sunny sunday mornings and to wash too much. It's not a value as more the status ppl think you get from owning one. I couldn't own one as I know I would kill it in less than a week.

its obvious we both feel differently about GM and that's OK. Enjoy your tahoe or suburban or whatever it is.
It's always funny reading you irrational uniformed posts about GM.

The best part about this all is, I drive a 5 Series and my wife has Yukon, and it's our first GM product. But I'm objective about cars...I havent been let go from a project from GM. No ties to the auto industry.

Enjoy the BMW that you bought with your buddy or whatever you did..lol I can tell it's your first Bimmer...you have Bimmer feaver.

Be interesting to compare the overall size and weight of the Audi 4L V-8 to a current Hemi or Chevy LS.

The future in internal combustion engines is OHC turbo charged engines. OHV engines will be curious nostalgic museum pieces. People buy them because they like the sound or the look, not the performance. Corvettes are kind of like Harley's in that respect. Probably a big crossover between Corvette buyers and Harley buyers.

Soon we will all be driving electric cars anyway. Once they develop a practical fast charger the infrastructure for electric will grow to the point that gas cars will be curios. Sad but true.
The 4L Audi V8 is larger and heavier than a 6.2 OHV V8.

Seriously, how many time do I have to tell u, the BMW is just a car to me. I have 6 and they are by all other brands, one being a GM too. The M2 is possibly being replaced by a GT4, so no bimmer fever. It's a good car, but it's just a car. And again your reading what u want. I was never let go of a GM Gig. I actually left a new job because they did work for GM. Been doing it too long and now how they operate. I was asked by GM when I started my own business if I would assist them and my reply was No. It also comical on my end to read your replies that twist my words. My sourness to GM is due to the lack of quality of their products post bailout and the way they treat their suppliers. Plain and simple.....
Because I AM tied to the auto industry. I see what happens in the background that ppl that do not have ties cannot.

Kinda funny that you think my post are not viable, as you have only owned one GM and I have owned 20+. So who has more real world experience with GM? Kinda like your DSG comment., as I would bet a hamburger you have never owned one. All your information is via armchair internet browsing. All my information is from real world owning or working with the product/company.

after you have owned 20 GM products.... one of them better be a corvette..... and spend a few decades in the auto industry as a career, come back and let me know what you think. Until then, your opinion on the brand means nothing to me.

Case in point - Porsche 911 is talking about making there 2020 cars electric and GM with there Vette lineup is talking about putting a gasoline engine in their cars mid vehicle........talk about 20 years behind the curve!!! And it is that in part what makes GM a loser company in my books.

Audi 4.0 TFSI engine weight 493lbs, and the 493 doesn't include the weight of the turbo's or inter-coolers.
LS3 6.2 V8 engine weight 411lbs

These are dry weights.

Small difference when you consider that the Audi can produce much more hp and much more torque. Also the TFSI torque is available at a much lower rpm.

Advantage Audi

Not really though, considering the LT5 produces more HP and more torque, and it's around 100 lbs lighter. The LT5 only produces 715 ft lb at 4400 rpms.

Are you really trying to compare a boosted engine and an NA engine? Anyone can make HP with boost and today's fuels.

I don't know all the Audi engines but (https://www.caranddriver.com/audi/s6) shows 450hp and 406ftlb tq

The 6.2 vette is 650hp and 650ftlb tq in boosted version (like the Audi) and 460hp, 465ftlb tq in the NA version (https://www.chevrolet.com/corvette-life/engines)

Are there other versions that can match these plus extra for weighing more?

So what? Is there a separate lane on the highway for naturally aspirated cars?

The LT5 is supercharged and produces considerably more power than the Audi 4.0TFSI.

You seem to be not understanding there is more than one small block.

Its going to be heavier too with the supercharger.

Imagine what Chevy could do with a supercharged DOHC LT5

Quite clear on that. Pitiful that they still use the OHV design from the 1940's.

If OHC engines are inferior why is Chevy promising one for the Mid Engine Vette in the future?

Because and OHC cylinder head will allow for better port design. It will also allow individual cams to be advanced or retarded to make more power over a broader span. Bottom end has to stay together, top end if where the power is made.

Comparing apples and oranges due to 4L vs 6.2L. The Audi makes more HP per CI.
