                  Ah, complication equals profit when these many units start dying.

                  And making a car engine in service that gets 7% of it's fuels energy to move it to 8% for all that cost is just not smart.  Far better go directly to EV drive with it's 20-65% eff depending on the power source.

                 The only eff way to use an ICE is running at constant speed driving an alternator which doesn't require complicated junk to be eff, cleanish as an ICE can be.  The Lotus EV Range Extender is an example of the future ICE in vehicles.

                Far cheaper is lighter unibodies, better aero and even chopping off a wheel you get into the 100mpg and up class.  Even the smaller SUV's could do this if they wanted to.

Hello Iron,

This article should give you a little background...

http://articles.latimes.com/2011/apr/01/news/sc-dc-0402-traffic-fatalities-20110402

Because of added safety features, infotainment, SMOG control the actual weight of cars has risen substantially over the years.

Also on a plus...

Technology is getting us back on track to the 40mpg 4-door of the past!

Can anyone explain this to me? In 1972 I bought a new Dodge Colt 1600, made by Mitsubishi. It could seat 4 normal sized adults, regularly got 40+ miles to the gallon and had enough get up that I got a ticket for doing 77 in a 60 mph zone. (I was younger then, so cut me some slack.) It had a 2bbl carb and coil ignition so I imagine the exact same vehicle would perform better today with fuel injection and electronic ignition. The car cost about $2200 as I recall and the only extraordinary maintenance I had was to replace the differential at about 55 thousand miles.

For some reason other cars liked to run into it while parked, sitting at a stop sign or just drivng normally. After the 4th such occurance we got rid of it. My question: how is it that a car like that could be built in the early 70's, without onboard computers, 40-70 pounds of wire, etc. Are we not smarter today? I'm just asking.

very good point. I did not even think about this fact.

Thanks

Compilers have been/are being updated to support multicore for the appropriate platforms.

However, multicore processors may be used without the hard requirement for a multicore-aware compiler. It depends on the actual chip architecture, as well as the software application design and partitioning.

Good example of evolution at work. Improvements in one place, i.e. multicore chips, lead to improvements in  others like powertrains.  

I thought this required changes in compiler design to take advantage of multicore chips.  Perhaps that was in the cae of parallel programming.  I am not sure that applies here but perhaps someone could speak up on that.

I would also expect the multicore design to be extended to additional cores just like our workstations are now quad core, hexcore or even octo core designs.  I think this saves power on the chip as well since the multicores reduce the need for higher clock speeds.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
