a new development path. Toyota stated the eighth-generation Hilux received larger cabin space front and rear with extra shoulder room, extra head room, higher seat height and larger rear knee room. It also feature a broader seat adjustment range and a larger fuel tank. It is also equipped with rear air vents as an option, making it one of the few pickups in its segment with rear air vents at the time of its launch. The front bumper has a bigger bulge to meet new pedestrian safety regulations, while the lower section of the front bumper has been shaped to ensure the Hilux is more agile than its predecessor in off-road conditions. In the Middle East, the Hilux received an optional steel front bumper. The approach angle is 31 degrees and the departure angle is 26 degrees, compared to the previous 30 and 23 respectively. The new ladder-frame chassis gives the vehicle a 20 percent increase in torsional rigidity compared to the previous generation model. The stronger FIRM (Frame with Integrated Rigidity Mechanism) makes use of high-tensile strength steel and more spot welds. The improved body structure is said to yield lower noise, vibration and harshness levels. It is also equipped with a newly developed Dynamic Control Suspension system and Body Control with Torque Demand. Three different suspension setups are available for the Hilux for different markets. Vehicles destined for Australia, South Africa, Russia and South America receive an Australian-developed heavy-duty suspension setup that offers improved off-road performance, better vibration suppression and improved roll stiffness. Vehicles sold in Thailand receive a comfort-biased setup due to the large market of pickup trucks for personal use. The third suspension setup is a general setup that is "suited to all road conditions the world over." The suspension used is a front double wishbone with a thicker front stabiliser bar and rear leaf spring configuration. It is aimed to give the Hilux a more "car-like" driving experience. Markets Argentina As of 2016, the Argentine version has about 40% of locally and 60% of regionally made parts. Australia During its introduction in Australia, the eighth-generation Hilux was offered with 31 variants, eight more than its predecessor, with 4×2 and 4×4, single, extra and double cabin styles, and WorkMate, SR and SR5 grade levels. Toyota has also added Hi-Rider variants for SR and SR5 models, with added ride height, heavy-duty suspensions, larger front ventilated disc brakes
