Rather than being directly based on the now larger Accord, the new Ascot was given its own platform, with the codenames CE4/5, which was a platform improvement of the previous generation. Like the Inspire, Vigor and the even larger Honda Legend, the CE Ascot had its engines mounted longitudinally, contrary to the Accord and most other FWD cars, employing the transverse setup, thereby placing the weight of the engine aligned and behind the front axle and improving vehicle weight distribution between the front and rear axles. In Japan, the smaller G20A engine used regular grade fuel, while the larger G25A engine used premium grade fuel.
