Analysis of GAC Aion's Chassis Performance
2 Answers
GAC Aion chassis analysis: The Aion demonstrates excellent chassis flatness. Protective plates are installed beneath the front engine compartment, at the front end of the power battery, and on both sides, effectively reducing aerodynamic drag during high-speed driving. Its powertrain consists of a permanent magnet synchronous motor paired with a single-speed transmission - the most common configuration in pure electric vehicles. Additionally, it employs an aluminum alloy subframe, achieving weight reduction while optimizing front-rear weight distribution. The transmission is wrapped with sound insulation material, which helps improve NVH performance during operation. The Aion features MacPherson strut front suspension, with ventilated brake discs and single-piston calipers in the front braking system. The rear braking system uses solid brake discs with single-piston calipers, with an electronic parking actuator located inside the caliper. The rear suspension adopts a torsion beam setup, and the overall suspension tuning delivers a premium driving feel. Chassis introduction: Refers to the automotive system composed of four parts: powertrain, running gear, steering system, and braking system. It supports and mounts the engine and other components/assemblies, forms the vehicle's overall shape, transmits engine power, and ensures normal operation. Chassis maintenance: Regularly inspect lubricants in all assemblies, replace worn brake pads promptly, perform wheel alignment for safety, and optionally apply protective coating to the chassis.
I've been commuting with the Aion S Plus for a year and a half, and the chassis performance has been quite impressive. The front MacPherson and rear torsion beam setup filters out vibrations cleanly over manhole covers, with sufficient support for cornering at 60 mph. What's most unique is the battery pack being directly integrated into the chassis longitudinal beams, resulting in such strong body rigidity that the car doesn't wander even with one-handed steering. However, the rear suspension can get a bit bouncy over consecutive speed bumps. Once when I scraped the underbody guard, the mechanic mentioned the aluminum alloy battery casing is 30% lighter than traditional steel plates, though the downside is higher repair costs for underbody damage. Daily driving reveals a chassis feel close to a B-segment gasoline car, feeling more substantial than Japanese electric cars at the same price point.
