White House Issues New Gas Mileage Standards
Hugh Pickens writes "NPR reports that the Obama administration has signed off on the nation's first rules on greenhouse gas emissions and set new fuel standards to meet a fleet-wide average of 35.5 mpg that will raise current standards by nearly 10 mpg by the 2016 model year. Although the new requirements would add an estimated $434 per vehicle in the 2012 model year and $926 per vehicle by 2016, drivers could save as much as $3,000 over the life of a vehicle through better gas mileage, according to a government statement. 'We will be helping American motorists save money at the pump, while putting less pollution in the air,' says Transportation Secretary Ray LaHood. Dave McCurdy, leader of the Alliance of Automobile Manufacturers, a trade group representing 11 automakers, says the industry supports a single national standard for future vehicles. 'Today, the federal government has laid out a course of action through 2016, and now we need to work on 2017 and beyond.' As the auto industry seeks to emerge from ashes, many manufacturers already are trying for the right mix of approaches, experts say. Some will try to sell more hybrids. Others are introducing not-so-gas-guzzling SUVs. They may also push slightly downsized and small cars, such as the Ford Fiesta."
Ford makes class leading cars in the UK. Not just "average cars" - they make genuinely desirable, high quality, class-leading cars in several size/usage classes with some of the best handling and best engines available.
There is no reason for them to be selling shit in the US, which is essentially what they are doing with all but their trucks. They make some amazing vehicles, and do so profitably in Europe.
The engines they sell *right now* in the UK are way, way above what these CAFE proposals are mandating. They don;t even need to do any reseach so there;s no "bankrupting" going on - they just need to bolt those engines into the US models, or just tweak the UK models slightly so that US licence plates fit onto the back (ours are thinner but wider) and Bob's your uncle.
Maybe also tweak the screen slightly - I remember a story somewhere about the US safety requirement for airbags is to assume the occupant is not wearing a seatbelt, so the screen has to be more upright to account for this in some models. Just lobby to have that common sense thing changed and we're done.
The big automakers in the US like to hide behind that "oh woe is us, it will cost too much and we don;t have the time to do the R&D, and the margins are too low" wailing, but they are really just dragging their feet. Ford is *very* competitive in the European market, and has innovated and picked its game up to get itself there, in the commercial and the consumer market. Hell, the light commercial it sells is the word for van in the uk: Transit Van, and you can't turn left without seeing a Focus, Fiesta, Mondeo, Ka and occasionally the odd Galaxy (I'm afraid the French have pretty much sewn up the soccer mom van market - it's the only segment Ford doesn't have a class leader in).
With some minor tweaks here and there (nowhere ear enough to bankrupt them), Ford could sell its Euro models in the US and be right on top of those regulations. Even if they skipped out all of their diesels (which are outstanding) and only sold the petrol ones, the lowest mpg petrol Focus they sell is 35.3mpg - for the automatic one. The worst diesel automatic does 48.6mpg (best does 74mpg, but you need the manual gearbox).
Overall, the U.S. transportation sector accounts for 33 percent of U.S. carbon dioxide emissions and highway fuel consumption for 20 percent.13 Other greenhouse gases from the transportation sector such as methane, nitrous oxide, and hydrofluorocarbons contribute an estimated 23 million metric tons of carbon equivalent,14 which is equal to about 5 percent of transportation carbon dioxide emissions.15 The remaining two thirds of U.S. emissions are attributable mainly to the industry and to industrial and commercial buildings and the energyusing devices they contain; this includes emissions from the generation of electricity, nearly all of which goes to the industrial and buildings sectors. The numbers show that U.S. greenhousegas emissions cannot be sufficiently reduced by focusing on motor vehicles alone, but neither can they be sufficiently reduced without a significant effort in the transport sector.
I got them from Ford's UK site, so presumably UK gallons - divide by 1.2 for US values, which makes the worst petrol automatic Focus 29.4mpg.
Frictional force exerted at the road is given by weight * coefficient of friction [u]. Since weight = mg that all boils down to mgu.
Lateral acceleration at a velocity v on a curve of radius r = v^2 / r. Since F = ma, The
lateral force = mv^2 / r.
As long as the first force is greater, the car is gripping. When it ceases to be, you skid. The limiting case is where mgu = mv^2 / r. The m cancels out, and you, sir, fail @ science.
