The Toyota NS4 advanced plug-in hybrid concept, which revealed at the 2012 NAIAS, is designed with future mobility requirements and focus on connectivity and the human interface.

NS4’s advanced powertrain targets a next-generation Hybrid Synergy Drive plug-in system featuring reductions in component size and weight with improved overall fuel economy, better acceleration and longer all-electric range, while maintaining a short charge time.

The Toyota NS4 styling lines reflect a new take on the aerodynamics of the modified triangle, with a low height and cabin-forward tilt. The distinctive open trapezoid grille is accented by a floating lower spoiler and wing-like daytime running lights wrapping around to a sculpted fender. Rear lamps wrap around the sides of the vehicle to quarter sections layered into blistered fenders, while the rear lamp wings create a sharp edge and the effect of a rear spoiler.

The A-pillars are ultra thin for improved driver visibility while maintaining roof crush integrity. The roof line profile, lift back design and powered swan-wing doors create greater accessibility and efficient functionality.

In term of connectivity, the Toyota NS4 concept’s Human-Machine Interface (HMI) provides a user interface built around a multi-touch screen with the look and feel of a smartphone. The simple, intuitive operation conveys information quickly while minimizing distractions and maximizing driver awareness. The multimedia and vehicle-controls enhancement also will direct air conditioning, audio, battery-charge and navigation functions.

The Toyota NS4 introduces a new Pre-Collision System (PCS) with lane departure, rear-end and pedestrian collision avoidance technologies designed to predict collisions under certain circumstances and help avoid them. This PCS uses millimeter-wave radar and stereo cameras mounted on the front of the vehicle to detect and react to lane departure, pedestrians and other vehicles. In addition, the system emits near-infrared beams to enhance PCS recognition at night.
