Handling and Ride
The smooth-riding Corolla is built around a stiff body structure that relies on high tensile-strength steel, gussets and cross members for its strength, rigidity and lightweight construction. Front suspension is composed of a compact, rigid L-arm-type MacPherson strut with a stabilizer bar. The Corolla's torsion beam rear suspension employs a coil-over-shock arrangement that allows efficient packaging along with solid handling and excellent ride comfort.
Brakes consist of 10.7-inch vented discs up front for all models and nine-inch drums in the rear. An electric power-assist steering system uses a compact motor, speed reducer and torque sensor built into the steering column. The system varies the amount of assistance according to engine RPM and vehicle speed. The result is appropriate weight and responsiveness at higher speeds, and light effort at low speeds. Electric power steering reduces parasitic losses to the engine, thereby aiding fuel economy. It is also environmentally efficient, because it does not require hydraulic oil.
Safety
The Corolla is engineered to absorb and disperse impact energy throughout the entire body structure, including front and rear crumple zones. Strengthened door beltline reinforcements help share the impact load, which in side impacts is also directed to the underbody. A direct tire pressure monitor system comes standard on every Corolla.
As part of the Toyota Star Safety System, Vehicle Stability Control automatically adjusts engine output and the vehicle's braking force at individual wheels to help control any discrepancy between where the driver is steering and where the vehicle is heading.
All Corolla models are equipped with six standard airbags, including advanced front airbags, front seat-mounted side airbags, and front-and-rear side-curtain airbags. Seatbelt pretensioners retract the seat belt at the time of a frontal collision, and the dual-stage force limiter helps limit the seat belt force applied to the passenger's chest. Front seats integrate active headrests. If the vehicle is struck from the rear with sufficient force, a cable-actuated mechanism in the active front headrest moves the headrest upward and forward to help limit the movement of the occupant's head. The Corolla also features an energy-absorbing steering column.
