1990 Eunos Cosmo
The 4th generation Eunos Cosmo started production in 1990 on the new JC platform. The Eunos Cosmo was the top-line touring flagship of the Eunos luxury channel. It is the only Mazda to use a triple-rotor engine. The car was a 2+2 coupé and was loaded with power amenities. Following the Japanese luxury theme, only an electronically controlled 4-speed automatic transmission was available. In Japan, sales were affected by the fact that this series Cosmo no longer complied with Japanese government dimension regulations, and Japanese buyers were liable for yearly taxes for driving a larger car compared to previous generations. Two engines were available, the twin turbo 13B-RE and the 20B-REW. The triple rotor 20B had a 2L displacement, making it the largest capacity rotary offered for sale by Mazda. It produced 224 kW (300 hp) @
6,500 rpm and 403 N⋅m of torque @
3,000 rpm with twin turbochargers. The Eunos Cosmo was the first production car to have a built-in GPS system, and the first in Japan to use the "Palmnet" serial data communication system for ECU-to-ECAT operation. This 4th generation Cosmo was ahead of its time electronically as well by being offered with Car Control System, a CRT colour touch-screen controlling climate control, mobile phone, GPS car navigation, NTSC TV, radio and CD player. The Cosmo was speed limited to 180 km/h (111.8 mph) to suit Japanese regulations, but the 20B-REW version was capable of 255 km/h (158.4 mph) if given a free run. With over 380 N⋅m of torque available at just 1,800 rpm, the Cosmo could launch from standstill to freeway speeds quickly; however, this came at the expense of heavy fuel consumption. The JC Cosmo was expensive even by today's standards, as Mazda still has not matched the sales price of this car some 22 years later for anything else in its range. The Cosmo was manufactured from February 1990 until September 1995, and gathered a total of 8,875 sales. A split of 60/40 sales between 13B-REW and 20B-REW variants made the triple rotor 20B-REW version a rarer car.
