Honda released the Prelude SiStates in 1990. Originally available only in Japan, this car was a limited production run and very few were built. It featured four-wheel steering, ABS, limited slip differential, a leather-wrapped steering wheel and gear lever, extra sound deadening on the firewall and hood, rear windscreen wiper and washer, and many more features that were usually options. It also featured a unique B21A engine rated at 145 bhp (108 kW) that was only produced for the SiStates. A major distinction of the SiStates is that it was the same width as the Prelude sold in North America. This Prelude model was only available with an automatic transmission.
