The 1988 Ibishu Pessima HX is marketed in the US as a high-efficiency sedan that uses a naturally aspirated 1.8-liter single-overhead-cam inline 4-cylinder engine. This model features a more aerodynamic grill/hubcaps, and anti-rolling resistance tires. The only transmission available is a 5-speed manual. While the vehicle is designed to save on gas, it promotes hypermiling which many consider to be dangerous on public roads.
