Car Moon

Fact: these official drawings of an unnamed Chevrolet sedan were filed with the U.S. patent office by General Motors. And well, that's where the facts end and the speculations start. Looking at the photos, we assume that this mystery Chevrolet four-door saloon with the Camaro-inspired rear-end design is either a mid- or full-size sedan.

And while we know for sure that General Motors is readying a redesign for its Camry-fighting Chevrolet Malibu, we're not at all certain that this is the car depicted here.

For all we know, it could be a replacement for the Impala or (less probably) maybe for the European market and Daewoo-based, Chevy Epica sedan.

Hit the jump to check out the rest of the drawings and tell us what you think in the comments section.

GM’s Aussie brand has unveiled the 2009 Epica Sedan which is also known as the Chevrolet Epica in Europe and as the Daewoo Tosca in Korea. Styling changes are subtle as they are reduced to a new front grille, rear fascia and alloy wheels. Holden also upgraded the Epica’s safety equipment which now includes ESP and six airbags as standard across the range. -Continued

The most important changes are under the hood as Holden eliminated the 2.0-liter V6 petrol engine and replaced it with a new 2.0-liter turbo diesel unit that produces 148 Hp (110 kW). The new diesel model that gets a 6T40 six-speed automatic transmission with Active Select as standard, achieves an average fuel consumption of 7.6lt /100km or 31mpg U.S. Finally, the 2.5-litre V6 petrol model is also upgraded to a six-speed automatic transmission.
