What does the TNGA architecture of the Highlander mean?
2 Answers
The TNGA architecture of the Highlander is a car manufacturing concept introduced by Toyota, aimed at producing better vehicles. This architecture represents an upgrade in the overall system capabilities. Under the TNGA architecture, Toyota employs extreme aerodynamic designs, lighter body structures, and lower centers of gravity during car manufacturing, resulting in improved vehicle performance. The Highlander's body dimensions are 4785mm in length, 1910mm in width, and 1760mm in height, with a wheelbase of 2790mm. The Highlander's thoughtful electronic systems ensure convenience and safety during daily driving. The VSC stability system with TRC function ensures that the large Highlander maintains good controllability even on slippery roads. When the brake pedal is firmly pressed during parking, the HAC hill-start assist system activates, keeping the vehicle's braking system engaged even if the brake is briefly released, preventing the car from rolling backward.
The Highlander is built on Toyota's TNGA architecture, which refers to an entirely new vehicle platform that excites enthusiasts like me who love delving into automotive details. Simply put, TNGA stands for Toyota New Global Architecture. It standardizes the design criteria for chassis, body, and components, significantly enhancing vehicle performance. For instance, a lower center of gravity improves stability, increased body rigidity boosts safety, and shared parts reduce maintenance costs. Applied to the Highlander, this architecture delivers noticeably more agile handling—reducing body roll during high-speed cornering compared to older models—while also improving fuel efficiency. Additionally, the optimized aerodynamics reduce wind noise, making long-distance travel quieter inside the cabin. This isn’t just a technical upgrade; it translates to more reliable and cost-effective ownership experiences in daily driving.
