Phony new CAFE Standards

You may have heard that the CAFE fleet fuel economy standard for US car manufacturers have been raised to 35 mpg for 2016. On the surface this sounds pretty good, but it turns out these are phony numbers.
As described in the Edmunds Daily article, the CAFE mpg is calculated using a very optimistic method that has not been updated since 1975, and gives mpg numbers that are much better than the EPA window stickers show on new models. So, what looked like a good gain in US fleet fuel economy turns out to be a very tiny gain made to look larger with phony numbers.

From Jonathan: "I owned a Geo Metro with the 1.0L 3 cylinder engine, and 5 speed manual transmission. I think it was a 92 model. It didn’t have much pep and couldn’t go over 80 mph floored. It did get 48-49 mpg consistently." From Jerimiah: "I drive a 1993 Metro that I modified a bit. I just broke my previous records for fuel economy with it; my last tank of fuel was 648 miles on 9.75 gallons - 66.5 mpg. That was 55 mph interstate driving."

Honda Clarity Fuel Cell Car -- drive report http://www.autobloggreen.com/ ... This is quite a detailed report on the Honda Hydrogen fuel cell car and a drive in it from AutoblogGreen. Honda Clarity Website: http://automobiles.honda.com/fcx-clarity/ NEW Home Energy Station -- make Hydrogen at your home for the FCX...	This is Honda's very serious go at a fuel cell car. It is designed from the ground up as a fuel cell car. Plans call for introducing the car in limited numbers as lease vehicles in southern California in 2008. The specs make it sound like a practical, usable, high efficiency car -- the biggest problem being the availability of Hydrogen (and cost?). The "Home Energy Station" is interesting -- A home station that makes Hydrogen from NG, and uses waste heat for space heating. Its puzzling that this only achieves a "30% reduction in CO2 compared to home with IC engine car and electric heat"? Seems like it should do much better?
Toyota iQ City Car http://www.greencarcongress.com ... From Tree Hugger ... Crash test...	Toyota's innovative iQ city car carries 3 adults and a child. Very compact (10ft long). Presumably very good efficiency -- maybe 54 mpg in the European rating. More details coming in early Oct of 08 at Paris auto show. To be in production by late 2008. Toyota has talked about a hybrid model later.
VW Polo Diesel -- 71 mpg, 87 g/km CO2 http://www.autobloggreen.com/...	All new Polo concept car that is due to come to US in couple years. Claim is 71 mpg and 87 gm/km of CO2. This would make the most fuel efficient 5 passenger car on the road.

They should be little hot rods with the equivalent of 200 peak HP. Powered by Li batteries and an advanced AC power plant -- said to have about 150 mile range. They will be leased ($850?/mo) in selected locations, including east coast and west coast cities. BMW is doing this to get real world experience with electric vehicles.
Saturn Vue Green Line will offer 2-mode and plug-in hybrid technology http://www.autobloggreen.com	GM has committed to introducing several new hybrid cars over the next couple years, including the first production plug-in hybrid. The plug-in will have an about 10 mile all electric range. Finally some signs of life from Detroit.
Prius PlugIn Hybrid www.hybridcars.com...	Toyota announces a plug-in hybrid version of the Prius. Specs are a bit underwhelming (10 mile electric range), but maybe helpful to some. A question one might ask is do plug in hybrids result in lower GHG emissions when you include the GHGs from the grid electricity used to charge them? Here is a report: http://www.epri-reports.org/ To me, it looks like the answer is that there is no real emissions saving until we get a cleaner electric grid. Of course, you can always charge from your own solar electric rig.

Target price is around $20K. I have to say that the video makes it appear to be a very fun car to drive. Kind of a cross between a motorcycle and a car with an outstanding view of the scenery.
Diesel-Hybrid Pickup Coming to US, From Treehugger http://www.treehugger.com/ ...	A diesel-hybrid pickup to be introduced in 2010 with the potential for 40 mpg. From Mahindra. Not sure I quite believe this, but their tractors have a good reputation.
MDI Air Car http://www.popularmechanics.com http://www.theaircar.com/ http://www.theaircar.com/howitworks.html	MDI seems to be serious about introducing several versions of a car that runs on energy stored in compressed air tanks. The compressed air drives a piston engine. They are also planning a version with an onboard fossil fuel compressor to make compressed air as you go -- a sort of air hybrid. I could not find any information on CO2 emissions for the energy that is used to compress the air. It would be nice to know how these air cars compare to pure electrics, hybrids, and plug in hybrids on total CO2 emissions, with the electricity sourced from coal or NG power plants -- please let me know if you see this -- Gary. (thanks to Jerry for suggesting this item)

Batteries appear to be the clear winner from this point of view. (Thanks to Ron for finding this)
Determining EPA fuel rating for plug-ins is difficult New York Times Article ...	New York Times article on what the EPA is going through to try to come up with the EPA gas mileage that will go on the window sticker for the Chevy Volt. Complex because the Volt runs 40 miles on electricity in the batteries with no gasoline use, and after that runs on electricity produced by the onboard IC engine. I would also like to see CO2 emissions on the window sticker, including the CO2 from the grid electricity used for battery charging.
MIT's pint-sized car engine promises high efficiency, lost cost -- Ethanol empowers little engine that could Massachusetts Institute of Technology news office http://web.mit.edu/newsoffice/2006/engine.html	Article from MIT Tech Talk on a gasoline engine that uses direct injection of Ethanol to suppress knocking under high power demand situations. Claim is that this allows a much smaller, higher compression, turbo charged gas engine to power a car, with injection of Ethanol only when high power is demanded. The claim is that this could reduce fuel consumption by 30%, which is comparable to hybrids, but at a much lower cost.
Scuderi Engine -- Potential air hybrid http://www.scuderigroup.com	A new engine design that separates compression and combustion into separate paired cylinders. This may offer some advantages in efficiency (claim is that a 30mpg car becomes 40 mpg car), and the possibility of a compressed air hybrid at a lower cost.
Israeli Microturbine-Based Range-Extended Electric Vehicle From the Green Car Congress www.greencarcongress.com/...	An Israeli start-up is working on a range extended electric vehicle (REEV) that uses a small gas turbine for charging the batteries. This type of vehicle is electrically propelled, but an onboard generator is used when the batteries can't provide enough range -- this means no need for a lengthy charging stop on long trips. It is claimed that the gas turbine may use as little as half the fuel of an IC engine for battery charging.

A group working on developing the plug in hybrid -- a hybrid that plugs into the grid (or PV) at night to extend its range on batteries. The video gives a good overall description of the concept. A question one might ask is do plug in hybrids result in lower GHG emissions when you include the GHGs from the grid electricity used to charge them? Here is a report: http://www.epri-reports.org/ To me, it looks like the answer is that there is no real emissions saving until we get a cleaner electric grid.

PV Enhanced Prius Lapp Renewables Ltd. www.greencarcongress.com www.lapprenewables.com/hybrid%20project.html (this link may have gone dead)	The conventional wisdom is that cars use energy at such a high rate that tacking a few PV panels on top would not be of much use. Lapp has found that if you start with an efficient car, that you can indeed make a worthwhile improvement. The (admittedly non-optimum) prototype achieves a 10% improvement in mileage, and the potential for an about 33% improvement is discussed.
