Gm is working on the feasability of a V8 Alum engine block that would save about 100lbs in car weight. This sounds almost like the time when a car maker was working on a project of a Plastic engine block.

Both sound possible...functionable yes...longevity without problems...definite YES.

As a VW engine builder of 28 yrs I have seen the end results of the Alum engine case and the failures associated within. VW did initially have a Magnesium blend with the air cooled engines of lower HP but with the increase in power they did suffer some at an expense to the consumer.

Getting back to GM, I can understand the pressing problem with the demands for more efficient running engines in the MPG range. An engine can be tuned and tweaked only so much while the body/chassis weight will also be lightened too what extent will remain to be seen.

Cars are being made shorter...plastic bumpers built into the fenders/hood/body to conserve weight. Soon we will be driving a balsom (sp) wood bodied car.

A current TV commercial shows a wrecked (totaled) car with the presumably former owner driving another identical model lamenting it's demise. The wrecked car was front end damaged for a total loss. Is this to be the car of the future...one wreck and then junked?

Personally I feel that a 4 cyl with a Turbo would be the ideal car of the future other then the Hybred now being produced. The power of the 4 cyl and the Turbo giving the extra 2 cyls of power when needed for passing etc could still allow for some comfortable gas mileage.

Others... please give your opinion as I'm only one person with a limited point of view.

The Cadillac big blocks of the 60's and 70's were much lighter than their solid iron small block cousins. They had high nickel content that made the blocks tough as diamond yet light as a feather (not really).

You can Google up the info on GM V8 Engines.

They will be made at Tonawanda NY with all Aluminum fuel efficient technology.

Also are to be the next generation V8 in technology as reported two days ago.

$400 Million to be invested.

It's good to hear that Buffalo will be getting some new industry up and running.

A new car is cheaper than time in the hospital.

Oh Gawd, not again, GM has had some bullet-proof engine designs and then attempted to improve the wheel (reminder to engineers--there are only 360 degrees and you can't make it more round)--the Northstar is a real hot rod but designed to be unbuildable and had problems with the head bolt threads in the block pulling out--I am working on an all-aluminium 4.2 which GM engineers had the stupidity or audacity run the front diff through the oil pan--the head gasket labor rate is 25 hours due to the necessity to remove front timing cover, front suspension and front differential.

And now we are supposed to be excited about another GM "high tech" block? If this is the same crew of designers as the 4.2, they deserve to be fired.

What the hell? Advanced engine development is a positive thing, no matter how much the oldies love their old school push rods and other aging tech. GM has done amazing things with prehistoric engine technology but the fact is that its getting dated and the development of a modern engine is something to praise rather than bash.
