Maybe. Did you see my other post?
There are multiple versions of the Spartan-3E.
PDF page 2 here
http://www.xilinx.com/support/documentation/data_sheets/ds635.pdf
outlines the differences between the commercial XC version and the
automotive XA version.
The XA automotive version is designed to be low-cost but has wide-range
temperature support and has reliability qualifications. Otherwise it
offers a LIMITED feature set, limited speed grades --- in comparison to
the full commercial-grade Spartan-3E (that I own)
There are no (AFAICT) specific automotive "features" that make it an
extra special fit.

Richard wrote about the Xilinx Spartan-3E:
Well, when I try to find out information on Spartan 3 FPGA's on
Xilinx's web site, all the web sections have "Automotive" plastered
all over them.
Perhaps they are just trying to market to that segment. I believe the 3E is for embedded designs, i.e.
automotive
applications, etc.
No, they do have special parts rated for an automotive temperature
range, but that's not what the 3E is. All Spartan FPGAs are
general-purpose FPGAs. I have no idea what would be special in an FPGA
for an embedded design; nearly all FPGA designs are embedded, so I think
there would be no real market for an FPGA that was NOT suitable for
embedded designs.
