Underhood, both the SOHC and DOHC versions of Saturn's aluminum 1.9-liter four now feature sequential-port fuel injection. Horsepower and torque figures remain the same for '96, but there is a slight improvement in overall driveability. Both engines are happiest and most lively in the upper rpm range; the SOHC model produces 100 horsepower at 5000 rpm and 114 pound-feet of torque at 2400 rpm, while the DOHC model cranks out 124 horsepower at 5600 rpm and 122 pound-feet of torque at 4800 rpm. Our estimate is that 0-60-mph acceleration should mirror the previous generation's performance (8.4 seconds, coupe; 9.3 seconds, wagon). In conjunction with the sequential-port injection, the new cars are also fitted with a second-generation OBD-II system. OBD-II interfaces directly with the PCM (Powertrain Control Module) and monitors all emissions-related functions. Traction control is now available on both automatic- and manual-transmission cars.

Saturn retuned the valving on both the front and rear struts with new mounts for more-precise ride and handling qualities. The tri-link rear suspension utilizes two unequal-length arms to control lateral movement and a third to manage fore/aft action. Sportier SL2 models are fitted with a new 185/65TR15 touring radial from Firestone, with 175/70SR14s found on the base SL and midlevel SL1.

Although far from revolutionary, the refinements made to second-generation Saturn sedans and wagons should be sufficient to entice new buyers to Saturn dealers' lots and to provide current owners with due cause to trade up. The SL sedan is expected to begin at about $10,500, while the wagon will base at $11,995.
