VW News: Volkswagen Doesn't Have Enough Engineers To Meet New Emission Standards
So true, they say that the average company can hire 4-5 engineers for every executive they rid themselves of. Strengthening a company that becomes more innovative and creating jobs and new products. I love that Dell Technology has continued to reduce the bloated overhead of EMC Executives as they continue to streamline products, grow engineering and bring new and better products to market.

Industry News: New Proposal by EPA and NHTSA Reduces Fuel Economy Targets, Remove California's Ability To Set Standards
EU and China are both heading towards stricter standards than the US. As such like Drew pointed out, we will fall farther behind and give up our leadership position by reducing emissions standards from auto's to commercial business emissions. We are already loosing the Green race to China and the EU, how much more is America willing to accept in falling behind the world by trying to recapture the golden age of Empire building that is the past, not the future.

Picked up a new ride
Awesome ride, way too go and a very nice upgrade over the 200. All the best.

Industry News: New Proposal by EPA and NHTSA Reduces Fuel Economy Targets, Remove California's Ability To Set Standards
@regfootball @riviera74 I like both of your posts, I think that now is the perfect time for the Auto Industry along with California to come together and propose a new standard that they agree on protecting state rights and leading the fed gov to simplify with a new standard that California and the Auto industry can live with. I truly believe that what is best for both clean air, people and business is a single standard to build to that can be done world wide. China and the EU have learned the hard way due to acid rain and the environmental damage caused by our love of ICE auto's. Time to retire the 100+ year auto and move into the next phase of Auto engineering that will bring new and innovative products. We all know it will take probably 50 years to remove ICE auto's from the roads but that should not stop us from moving forward. Having a ton of relatives in the greater LA area, I know only too well what it was like visiting them every summer and just shaking my head at the smog, and they wondered why my parents moved in the mid 60's to Washington state getting away from the concrete jungle of LA. Time for a better way to move around. Hybrids, EV's, and high speed electric trains, tubes, etc. We have got to do things better, smarter and move society forward.

GM News: Tripower Making A Comeback At GM
I totally get what your saying but you know the LAZY Marketing dweebs are going to use it. We ALL have been disappointed with GM's marketing and creation of auto names. They have had some of the best concepts with names that I consider to be awesome and not really used any of it. Latest Cadillac concepts come to mind. 4th-ish, wow, guess I missed the first 3 Thank you for your honesty

GM News: Tripower Making A Comeback At GM
Really liked this one covering Thermal Dynamics in using waste heat from the engine to reduce fuel consumption by 4% and controlling oil temperature. https://www.asme.org/engineering-topics/articles/automotive/using-waste-engine-heat-in-automobile-engines WOW @Drew Dowdell I always find new and interesting things when questions like yours are asked.

GM News: Tripower Making A Comeback At GM
I was also wondering this and as I looked around found the following info to be informative: https://www.jcmmachineandcoatings.com/thermal-management/ Thermal management, as it applies to an internal combustion engine, is the idea of controlling heat and friction in order to attain the maximum performance, fuel economy, and longevity through the use of ceramic coatings. This is done through the use of thermal barriers, thermal dispersants, and dry film lubricants. Each of these categories is explained in detail in their corresponding pages. To fully understand the idea of thermal management, you must have an understanding of the first two laws of thermodynamics, they are as follows: 1st law - The law of conservation of matter and energy - Matter and energy cannot be created or destroyed, only changed. For example when you burn a piece of paper, it is not gone; it has changed into ash and smoke. 2nd law - This law states that heat has direction, it moves from an area of a large amount of heat to an area of a low amount of heat in order to achieve thermal equilibrium. Just as a hot cup of coffee cools off, the high amount of heat in the coffee is released into the surrounding atmosphere. Another example is an ice cube melting; in this case the heat in the atmosphere is absorbed by the ice and cool water to become the same temperature as the surrounding air. Good Read as presented on this subject from Clemson University. Advanced Thermal Management for Internal Combustion Engines.pdf SAE has a document they sell on this exact subject for maximizing engine performance. https://www.sae.org/publications/technical-papers/content/2006-01-1232/ Advanced Thermal Management for Internal Combustion Engines - Valve Design, Component Testing and Block Redesign Advanced engine cooling systems can enhance the combustion environment, increase fuel efficiency, and reduce tailpipe emissions with less parasitic engine load. The introduction of computer controlled electro-mechanical valves, radiator fans, and coolant pumps require mathematic models and real time algorithms to implement intelligent thermal control strategies for prescribed engine temperature tracking. Smart butterfly valves can replace the traditional wax-based thermostat to control the coolant flow based on both engine temperature and operating conditions. The electric water pump and radiator fan replace the mechanically driven components to reduce unnecessary engine loads at high speeds and provide better cooling at low speeds. However, implementation of electro-mechanical actuators including the alternator and electrical storage devices introduces inefficiencies in mechanical to electrical energy conversion (and electrical to mechanical energy conversion), which may require increased fuel consumption over pure mechanical components. Empirical models can provide realistic component data used in simulation tools during the development process, and also define the basis for cooling system control algorithms. In this paper, a general framework to derive these empirical models is investigated for thermal management systems where the engine temperature must be accurately controlled in both steady state and transient operation. The evolution of automotive cooling systems also requires a paradigm shift in the engine block design. The design changes include isolated cylinder water jackets, temperature sensor arrays, and distributed smart valves to enable distinct cylinder-by-cylinder temperature maintenance for optimum combustion. This paper explores the introduction of a ‘coolant rail’ to accommodate specific cylinder temperature control defined by an on-demand cylinder dependent cooling strategy. WOW, ? SAE even has a paper on Modeling of an Electric Thermal Management system https://www.nrel.gov/docs/fy15osti/63419.pdf Very interesting info on thermal management fluid loops for EV auto's batteries, cooling and heating systems.
