I read it. You're just wrong.


In order for Corvette to maintain its relative weight GM has had to resort to using entirely different materials. These materials COST MORE to maintain an overall vehicle weight that now includes airbags, ABS equipment, crash sensors, door beams, etc etc.

For the Mustang to do the same it can be reasonably concluded that Ford would need to take similar costly measures. As it stands it's pretty amazing that given the Mustang's size relative to the Corvette that it's so close in overall weight, AND that we're all comparing the Mustang to the CORVETTE and not the CAMARO, further proving my point.
Like I've said pages back, camaros is the apples to apples comparison, not the corvette and just changing everything as it relates to the size differences.

I'll just keep my fingers crossed that the GT PP comes in at 3350 lbs.
That means if push comes to shove, I can probably get it down to 3000 lbs down the road.

In all fairness that is incorrect. GM set out to save weight on the Corvette while making it a point "NOT" to use materials that would drive the price up. This is something I learned when we took the tour in Bowling Green last month. The car is not laden with expensive weight saving materials. In fact the most unusual material on the car was the use of balsa wood in the floor panels which is hardly an expensive material. The frame is still made of steel and the engine is aluminum as I recall. You won't find extensive use of carbon fiber and that sort of thing. This is how GM achieved super car performance in a car that costs 51 grand.

What? The frame IS aluminum and the hood and roof are CF, the rest is Fiber Glass...
Everything driveline is AL...

Jup. Also, no more wood in the C7.

Nope. I forgot what it's now, but they mentioned something about space age composite yada yada.

I thought it was balsa compressed between two sheets of something, etc etc. Could be the C6. The point being, Corvette is not a car that is laden with all sorts of exotic materials. It's pretty common stuff and they have just done a variety of things to save weight where they can. European cars by and large don't have to contend with that big heavy V8 up front and that alone saves them a lot of weight but it also means smaller high revving engines that don't have a long shelf life.

I could be wrong of course.
Regarding the engines, that's a common misconception as well.
There's a reason 90% of swapped cars use LSxs...
And it's not power. Lots of ways to make that happen.
What makes the LS sand out, is it's incredible compact and lightweight package!
It weighs almost exactly the same as the turdy cast iron I4 of a Miata!!!

True, but what does it weigh as compared to the flat six in the 911 for instance? Or the 1.8 in the Lotus?

I heard somewhere that the 1.8 engine in the Lotus is only good for about 40,000 miles and then you pretty much either have to replace it or rebuild it because it's run out due to how much power and pressure they are putting through it. Who knows if that's true. I'll take the lov rev, high torque of the American V6 / V8 motors anyday over those just because I know I can put 150 to 200K miles on it with no problem.

Comparing weights/weight loss with the Corvette is kind of silly to me.

One is absolutely not comparable to the other.

That was pretty much my point. The Mustang isn't that much heavier than the Vette so complaints about it being heavy just don't make sense to me. Not everything needs to be Miata light. I wouldn't buy a Mustang that was small and light like a Miata, that defeats the point.

Porsche Flat Farts are around 500 lbs, LS1s are 400.
Yeah... German engineering my sweet behind.
I know this is a Ford forum. I guess the Coyote is a little heftier than the LS with all those cams and valves? Either way, nothing beats USDM. Simple as that.

I'm not real critical of the Porsche flat six motors. You have to give props to a 3 . something liter that cranks out that kind of power. But I hear they are very maintenance intensive and if you don't pour a lot of maintenance into it the motor will pretty much kill itself. Again, just word of mouth stuff, who knows if that's true. On the other hand I have seen 4.6 Mustangs with 160K on the clock that still pull hard and have never had much done other than changing the oil and spark plugs etc etc. The old 4.0 Mustangs, although only 200 hp, it was a motor that would last forever with minimal maintenance. I haven't heard anything bad about the new 3.7 motor. As far as I know its reliable. I worry about this new ecoboost engine. Anytime you're getting that kind of power out of that small an engine I just worry about long term reliability.
