• FE1 suspension – standard on LS, LT and LTZ models, it provides a smooth ride and includes a 19-mm front stabilizer bar and a 16-mm rear stabilizer bar
• FE3 suspension – standard and available only on SS models, it delivers a firmer, more direct ride and includes 22-mm front and rear stabilizer bars, four-wheel disc brakes, monotube shocks and 17-inch wheels and performance tires
• FE5 suspension – standard on the SS Supercharged, it was developed on the racetrack to deliver sports car levels of handling and grip; 24-mm front stabilizer bar and 22-mm rear stabilizer bar, higher-rate springs and bushings, four-wheel disc brakes, monotube shocks and 18-inch forged aluminum wheels with complementing performance tires
From the outset, engineers designed Cobalt to be a responsive, fun-to-drive car. Cobalt’s underbody uses high-strength steel as welded members in strategic locations for maximum strength, structural integrity, mass optimization and crashworthiness. The underbody boasts a rigid bending frequency of nearly 27 Hz.
All Cobalt models feature a strut-type front suspension, semi-independent torsion beam rear suspension, and front and rear stabilizer bars for more exact body roll control. Speed-sensitive electric power steering is tuned to match the performance levels of the various tire and suspension packages.
The Cobalt rides on a MacPherson strut front suspension and a semi-independent, torsion beam rear suspension. Front and rear stabilizer bars – uncommon features for compact cars in Cobalt’s price range – are standard on all models. Suspension tuning for each model, including steering feel, spring rate and stabilizer bar diameter, is dialed in to provide distinct driving and handling characteristics.
Cobalt’s strut-type front suspension is compact yet provides long wheel travel, with 90 mm of compression travel and 87 mm of rebound, which is substantially more than most competitors and enhances overall ride and handling. Monotube rear shocks are used for a more precise road feel. L-shaped front control arms contain a forward pivot bushing, which transmits most of the cornering force, and a larger, high-damped composite rear elastomeric bushing that allows rearward movement to minimize harshness from road surface impacts. The front control arms are made from steel on the FE1 suspension and are aluminum on the FE3 and FE5 suspensions.
The direct-acting front stabilizer bar connects to each strut for precise steering response and improved cornering agility with decreased body roll. All front suspension components are mounted to a new, rigid cradle assembly comprised of four large hydroformed steel tubes and two side members that are integrally welded to front and rear cross members. The cradle is mounted to the Cobalt’s space frame at four widely spaced points.
Cobalt’s torsion beam rear suspension provides excellent ride and handling, while maximizing interior space. A hydraulic rear suspension bushing is employed on the FE1 suspension to improve the ride and suppress road noise. Rear wheel travel, at 126.5 mm in jounce and 68.5 mm in rebound, is longer than most vehicles in the segment.
Vented front disc brakes with single-piston calipers and composite rear drum brakes are standard on LS, LT and LTZ. Four-wheel anti-lock brakes (ABS) are standard on LT and LTZ models, and optional on LS. Four-wheel disc brakes with ABS are standard on SS and SS Supercharged models. Cobalt also offers an enhanced electronic traction control system on all models equipped with an automatic transmission and ABS; this system is standard on LTZ.
Enhanced traction system (ETS) is integral with automatic-equipped Cobalts with ABS. ETS enhances traction by adjusting engine torque if wheel slip is detected.
