Sales fell 3.7% in November, worse than the staggering 34% drop in October.
Sales tracker Autodata said that its preliminary total showed industrywide sales at only 746,789 vehicles, the first time sales have been below the 750,000 mark since January 1982.
General Motors wants a $US18 billion loan from the US Government, Ford wants $9 billion and Chrysler wants $US7 billion.
That's $US34 billion in all, compared to the original offer from Congress of $US25 billion.
GM said that so fraught was its current financial state it needed $US4 billion of its request right now to avoid bankruptcy.
Ford said in its plan that it planned a major reorganisation and said it would break even or restore profitability in 2011 if lawmakers approve up to $US9 US dollars in emergency financing.
GM asked for $US18-billion, vowed to pay back $US12 billion by 2012 and said it would review its Saab and Saturn labels to focus on core brands. In addition it will shed 31,500 jobs.
And struggling Chrysler told lawmakers it needs $US7 billion dollars by the end of this month to survive the combination of a global credit crisis, falling demand for large vehicles and a worldwide economic slump.
So, with GM and Chrysler needing money urgently this month, the US Congress now knows that when they start discussing the plans tonight, our time and tomorrow, it will be a life and death argument.
Unlike GM and Chrysler, Ford does not believe it will run out of cash next year, but needs access to the loan in case the economy worsens.
Chrysler, the smallest of the Big Three Detroit automakers, said it will only have around $US2.5 billion in cash on hand by December 31 after a "significant downturn" of the US automotive sector in the second half of the year.
"Without an immediate working capital bridge, Chrysler's liquidity could fall below the level necessary to sustain the company through the first quarter of 2009," the company said.
GM, which has warned it would run out of cash as early as January, said it will focus its product development and marketing efforts in the US on four core brands - Chevrolet, Cadillac, Buick and GMC.
The automaker said it would need the $US12 billion to cover operating costs through to the end of 2009 and also requested a revolving credit line of $US6 billion to "provide liquidity should a severe market downturn persist".
Seeing GM burned through cash at the rate of $US2 billion a month in the September quarter, and probably more this quarter, it still looks to be on a knife edge, even if it gets the money it wants.
Apart from some window dressing on salaries and private jets, those announcements from GM and Chrysler were the most dramatic points to emerge from the three plans.
Ford, GM, Chrysler, Toyota and Honda all reported drops of more than 30%. The annual sales figure rate were 10.2 million, a 26 year low and down from 16.1 million in 2007.
Chrysler's was closer to 50% and GM's more than 40%: it was a devastatingly bad set of figures and will help buttress the begging bowls GM, Ford and Chrysler have produced in Washington this week for help from the Federal Government.
GM wants more cash than it currently has on hand (less than $US16 billion). Ford is in a better position, but its $US9 billion request would see it continue with certainty until well into 2010 when the expected recovery comes: if it comes of course, such is the gloom surrounding the sector now.
Between them the three companies would absorb more than the $US25 billion on offer.
GM said it is seeking up to $US12 billion to survive into 2010 and that it anticipates using $US4 billion of that just this month in order to avoid bankruptcy.
It also asked for an additional $US6 billion line of credit to provide more funds should a severe market downturn persist.
Seeing its recovery plan is based on a 12 million vehicle year in 2009, there's every chance that could be called on given the extent of the slump in demand now and expected in the first quarter.
Chrysler repeated the $US7 billion request of two weeks ago in its filing with Congress this morning. Chrysler still has to resolve the outstanding stake held by Daimler and what happens to the 51% of GMAC owned by Cerberus, which owns the other 79.8% of Chrysler.
The $US34 billion asked for is more than a third higher than originally offered by Congress.
The CEOs of GM and Ford offered to work for $US1 a year and both companies said they would get rid of their contentious private jets.
The three executive groups drove 800 kilometres from Detroit to Washington on Monday night and Tuesday morning. No quick jet trips to Washington this time for the new hearings; something which undone their requests last month
GM said it believed industry wide US car and light truck (SUV) sales fell by 400,000 vehicles, or 34%, from a year ago, which would be well below even October's total.
"GM car sales of 58,786 were off 44 percent and truck sales of 96,091 were down 39 percent.
The steep decline in vehicle sales was largely due to a significant drop in the market's retail demand compared with last year, and continuing economic uncertainty that has negatively impacted consumer confidence.
"In November we saw the continuation of the dramatic decline in volume for the industry. Every manufacturer is posting awful numbers and we are no exception," said Mark LaNeve, vice president, GM North America Vehicle Sales, Service and Marketing.
"There were about 34% or 400,000, fewer vehicles sold this November in the industry than a year ago - this is the annual volume of two full production plants that have simply evaporated in a single month.
"The global economic crisis and credit freeze have had a very negative impact on the vehicle market which runs on consumer confidence and available financing."
Mr LaNeve said last month that the slump in October was the worst month for the company since the end of the second world war: November ups the ante.
GM reported a 41% drop from a year earlier and a 9% decline from October's sales.
Sales of light trucks tumbled 39%, while cars fell a staggering 44%; Chrysler reported a 47% drop from year-ago levels and a 10% decline from October; Ford said November sales plunged 31% from November 2007 and sales were also down 7% from October.
The real surprise was the slump in sales for Toyota and Honda.
Toyota said its sales fell 34% from last November and 14% from October; Honda reported a 32% drop in sales on last year and sales were down 11% from October.
Toyota's position has worsened appreciably in the past few weeks.
Seeing it's the market leader in Japan, and very big elsewhere, it was hit hard by the 27% slump in car sales in that country last month (sales in South Korea also fell 27%). Honda and Nissan Renault were also hit.
Toyota is cutting bonuses for its 5,000 top managers by 10% and has scheduled a press conference next week where it's expected to reveal lowered sales estimates for 2008 and calendar 2009.
It has already slashed its 2009 earnings estimate by around 60% and is expected to earn just $US200 million in the six months to the end of March. Given the slump in Japan and the US last month, that is now in doubt.
Honda has already warned it may lose money in the March half.
GM and Ford also announced big cuts in first quarter production for 2009: they are not waiting for sharply lower petrol prices to boost demand they are cutting and cutting deeply.
GM will hack its US first quarter production by 32% to 600,000 vehicles, while Ford will slash production by 38% to 430,000. They are lower than the current rate of output for both companies.
