Two models were offered: AN68/1R (9.4m in length) and AN68/2R (10.2m in length). Power assisted steering was standard on the AN68/2R and optional on the AN68/1R. The steering pump was power driven, which replaced the early belt driven system, while the only available engine was the new Leyland O.680. A wide variety of body styles from various manufacturers continued to be offered, allowing the Atlantean to be tailor-made to requirements from operators ranging from the small independent to the large city corporation.
