Yes. Saab's Ecotec 2.0 is a square design, 86mm x 86mm; it's essentially a marriage of a shorter stroke Ecotec 2.2 with a Saab-designed head. Depending on the fans you believe, it's Saab than Ecotec - Saab took the 2.2 and decided they could do better.
That's something of a marketing trick, I'm sure - designed to emphasise the premium end of the stable I suppose.
For what it's worth, the TTiD is a silly piece of kit and for all the right reasons. :-)
