Named to honor the company's 25 year anniversary in 1988, the 25th Anniversary Countach was mechanically very similar to the 5000QV but sported much changed styling. The rear 'air boxes' were restyled and enlarged, while the vents behind them were changed so that they ran front to back instead of side to side. In addition, a new air dam and side skirting, both with air intakes, were fitted, and the taillights were restyled to be narrower, with body-colored panels replacing the upper and lower parts of the previous large taillights. The styling changes were unpopular with many, but did improve the engine's cooling, a problem the Countach had always struggled with.
