MEMORANDUM

SUBJECT:	FEV Cost Study Results for 3 Newly-Evaluated Cases

DATE:		September 11, 2009

The United States Environmental Protection Agency (EPA) has contracted
with FEV, Inc. to determine incremental direct manufacturing costs for a
set of advanced light-duty vehicle technologies.  The methodology for
this study has been documented in detail in a draft report prepared by
FEV and its subcontractors: “Light-Duty Technology Cost Analysis Pilot
Study”.  This report also presents results for the first technology
evaluated: stoichiometric gasoline direct injection (GDI) with
turbocharging on a downsized I4 engine, compared to an equivalent
conventional I4 engine.  The report is currently under peer review.

Since the completion of the draft report, 3 additional cases have been
analyzed using the methodology documented in the report.  These cases
are:

1) Stoichiometric GDI with turbocharging on a downsized I4 engine for a
mid-size car, compared to an equivalent conventional V6 engine.

2) A 6-speed automatic transmission (AT), compared to a 5-speed AT.

3) A Dual-Clutch Transmission (DCT), compared to a 6-speed AT.

The results are summarized in the following table.  These results should
be considered preliminary, as peer review of the study methodology has
not yet been completed, and the detailed analyses for these 3 cases are
still under review.  Note too that these results are direct
manufacturing costs.  They do not reflect additional costs at the
original equipment manufacturer (OEM) level included in indirect cost
multipliers (ICMs).  Further details on these results are attached
directly to this memorandum.  Due to the large size of the spreadsheets
that document the detailed analyses, these detailed results are not
attached here, but are available on a CD being docketed with this
memorandum. 

New Technology	Incremental Direct Manufacturing cost for new technology

Turbocharged GDI on a downsized I4 engine compared to V6 engine	$107.95

6-speed AT compared to 5-speed AT	($102.54)  -- a cost savings

DCT compared to 6-speed AT	($244.23)  -- a cost savings
