T40,
As someone who works in the auto industry, I don't think I'd use the word "rosy". But I'll stick to my position that today's cars are more efficient and generally better in every way than those produced in earlier decades. They're faster, safer, more comfortable and certainly more reliable. Of course they are also more expensive and complex; that's the way things go.
I was a bit surprised that you used the venerable GM small block and big block engines as examples of fuel efficiency. GM replaced these dinosaurs years ago with more modern engines that deliver the power and efficiency demanded by customers and EPA regulations. And although you can argue that the old cast iron engines were better than the plastic and aluminum of today, it's the new engines that carry 100,000 mile powertrain warranties.
Yes it's true that many technologies were first developed years ago, Using fuel injection as an example, it's been around since the thirties. But it took technology and demand to bring it to the mass marketplace. Techology in the form of cheap and powerful microprocessors; demand from both customers and federal efficiency/emissions regulations.
Not that it's really relevant, but it is not true that turbocharging miraculously increases both power and efficiency. If it did, every new car on the road would be turbocharged. Turbocharging increases the effective displacement of an engine by pumping more air through it. But the engine's compression ratio must generally be reduced to allow turbocharging. And compression ratio is the single most important factor for power and efficiency in an internal combustion engine.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
