 1968 introduced the Endura 'rubber' front bumper on the GTO, the precursor to modern cars' integrated bumpers, and the first of a series "Ram Air" engines, which featured the induction of cold air to the carburetor(s) for more power, and took away some of the sting from deleting the famous Tri-Power multiple carburetion option from the engine line up.This Tri carburetor deletion came from the 14th floor of GM banning multiple carburetion and headed by GM president Ed Cole.The Ram Air V garnered much auto press publicity, but only a relative few were made available for sale.
