6. Nissan Skyline GT-R (R32/R33/R34)
The Nissan Skyline GT-R models of the 1990s were technological marvels, notably equipped with the Advanced Total Traction Engineering System for All-Terrain (ATTESA) all-wheel-drive system. This system utilized two accelerometers to monitor lateral and longitudinal forces, enabling the electronic control unit (ECU) to adjust torque distribution between the front and rear axles in real-time, enhancing traction and stability. Introduced in the R32, the ATTESA system evolved over the years, with the R33 and R34 models featuring the more advanced ATTESA E-TS Pro, which included an active limited-slip rear differential for improved handling. Additionally, the GT-Rs were equipped with the High Capacity Actively Controlled Steering (HICAS) system, which steered the rear wheels in the same direction as the front at higher speeds to improve turn-in response. These sophisticated systems collectively made the GT-Rs of the 90s ahead of their time in automotive technology. (en.wikipedia.org)
