It's not a simple inverted wing...he's got a steep angle, plus a lower wing - l assume to keep flow attached. I recall a reference where Colani was inspired by a water beetle wrt the Corvette (on a C4 chassis!). The 1000 passenger jumbo jet is further down the page.
My skill in 3D modelling doesn't yet allow me to wrap a representative body around four wheels to do a CFD study...never mind get Cd 0.19 with plenty of downforce.
edit: l just realised that l was down the street from the Design museum in London, three months after the Colani exhibit (march - june 2007) o.O
p.p.s. Colani's website, of course
