UPDATE! After careful comparison with the new seventh-generation Golf we are now sure that the heavily disguised prototype here is the new Golf Variant not the next-generation Volkswagen Passat Variant as we suspected at first.
Thanks everyone for pointing it out!
To err is human; to forgive, divine.
The new Golf Variant is expected to arrive in early 2013 with the same engine range found in the standard model. All engines come with a Stop/Start system as standard, along with battery regeneration. Depending on the engine, gearboxes include five- and six-speed manuals, and six- and seven-speed DSG units.
