this is what Bob Lutz said in a story

'On the growing size of domestic cars: "We have no plans to show a Cadillac 18 or 24. I think this year, just when everybody expects us to go longer, lower, wider, heavier, more cylinders and more horsepower, we may decide to surprise you in the other direction."

I guess the sts will be just a little larger then the cts

All the literature indicates that the STS will be taller than the CTS and in dimensions about the same as the SRX -- which has considerably mor second row legroom, for example, than the CTS.

Just to get all these threads on the same page, the best unmasked STS shot yet:

STS will be ~4" larger (OAL) than CTS.

c/d

All the literature indicates that the STS will be taller than the CTS and in dimensions about the same as the SRX -- which has considerably mor second row legroom, for example, than the CTS.

The SRX has 41.0 inches (36.2 for the CTS) of second row legroom. The
BMW 745i/745Li has 37.2 and 42.4 inches respectively. So 40/41
for the STS would be nice.
