Dick Teague. It also included features that were considered unique at the time. The instrument panel featured "a heavy dose of electronics", with all driver controls housed within a fingertip distance from the steering wheel. It used an unusual dash-mounted gear selector with a thin metal lever at the end of which was a grip handle; instead, if the gear selector shifted downward in the traditional fashion, the lever dropped into the dash pod in which it was mounted. The climate controls used an unusual up-down button that cycled through the different heating modes, indicated by an array of lights. All of these controls were housed in a control panel on the right side of the steering column. On the left side of the column, another control contained the light and windshield wiper controls. The turn signal control was also electronic returning to its centered position immediately after a driver signaled a turn, and a gong indicated its cancellation after completing a turn. The optional cruise control was built into the leather-wrapped steering wheel. Other features included intermittent wipers, as well as automatic variable-speed that adjusted wiper speed to the amount of water that hit the windshield; with less moisture, the slower they would move, but increasing their action if a passing truck splashed the windshield with a large amount of water. Standard on all Premiers was an electronically tuned stereo sound system. 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.
