There was a choice of two powertrains. Eschewing the Renault 25's French-built four-cylinder engines, the base Premier "LX" trim featured a standard 2.5 L AMC four-cylinder engine. Featuring electronically controlled throttle-body fuel injection, it developed a peak power output of and of torque at 1400 rpm. This engine was coupled to a new electronically controlled four-speed automatic gearbox, developed by ZF Friedrichshafen. Fuel economy for the base model was EPA estimated at in the city and on the highway, giving it a cruising range with the gas tank. Optional in the LX and standard in "ES" models was a 3.0 L version of the Peugeot-Renault-Volvo (PRV) V6 engine, fitted with multiple port fuel injection, producing peak power and torque figures of at 5000 rpm and at 3570 rpm. Fuel efficiency of the V6 was rated at for the city and on the highway. Factory acceleration estimates from standstill to 60 miles per hour (97 km/h) were 11.5 seconds with the four-cylinder, and 10 seconds with the six. The Premier's powertrains were covered by a 7-year, warranty, which was longer than offered by any of the competitors at the time.
