If you manage to take the rear end of the car out of said shark's mouth and prove it was a 4x4, then yeah, you could... :P

Resuscitating an old topic:

Here's the (latest) English version of the Octavia specs from https://az749841.vo.msecnd.net/sitesencom/alv1/81e46249-2ab3-4bc7-b2df-f5dbe22b0051/OCTAVIA-Catalogue.2ea01c77506a7547fff36678dd8f039b.pdf:

Page 93, under the FURTHER SPECIFICATIONS heading, Rear axle paragraph, reads:

Compound link crank-axle / 1.8 TSI; G-TEC; 4x4:
multi-element axle, with longitudinal and
transverse links, with torsion stabiliser.

Translated into common language, it seems that all versions except the three (1.8 TSI, G-TEC and 4x4) get the cheaper torsion beam rear axle ("crank-axle"), while the three get the multilink one ("multi-element axle, with longitudinal and
transverse links, with torsion stabiliser").

Hope this helps.

Cheers from Italy.
