Toyota Reveals NS4 Advanced Plug-In Hybrid Concept

‘Vision of the Future’ Concept Vehicle Features Advanced Powertrain, Human-Machine Interface and Safety Features

The Toyota NS4 plug-in hybrid concept debuts at the North American International Auto Show

DETROIT, January 10, 2012 – Toyota Motor Sales, U.S.A., Inc. (TMS), today revealed the NS4 advanced plug-in hybrid concept vehicle at the 2012 North American International Auto Show (NAIAS) in Detroit. The NS4 signifies Toyota’s vision for future mobility with a focus on connectivity and the human interface.

Toyota engineers were challenged to design a new mid-sized concept for potential global market introduction by 2015. The NS4 concept is a dedicated plug-in hybrid, separate from the Prius family, designed with future mobility requirements in mind.

“In this digital age, cars are becoming another spoke in the wheel of our electronic connectivity,” said Jim Lentz, TMS president and chief operating officer. “NS4 demonstrates Toyota’s take on the human connection to the car with technology that considers both emotional and rational relationships, person-to-car and car-to-society.”

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 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.

Increased Connectivity
Traditional vehicle development cycles average four years, but this is rapidly changing in the digital age. Vehicles have become another communication hub in the connected-consumers lifestyle and automakers must integrate the latest technologies into their product offerings. In fact, connected vehicles are the third-fastest growing technological device, behind smartphones and tablets.

Toyota has formed special alliances with technology leaders such as Microsoft, Intel and Salesforce to explore the creation of seamless vehicle interfaces with emerging technologies. These alliances will help ensure Toyota is at the forefront of this emerging sector of the automotive market.

The 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 HMI system is even capable of “learning” driver preferences and habits to anticipate driver responses in specific environments and situations. This concept represents a truly connected vehicle, offering the latest technology in a responsible and convenient package.

The pop-up hood structure automatically raises the rear of the hood to increase the space underneath, helping to reduce pedestrian head injuries caused by a collision with the front of the vehicle, within certain speed ranges. This innovation is the result of testing and verification using both conventional crash-test dummies and Toyota’s Total Human Model for Safety (THUMS) virtual model.

Using sub-millimeter wave radar, the Blind Spot Monitor (BSM) is designed to detect a vehicle in the adjacent lane and visually alerts the driver using visual indicators placed in the upper dash.

Four new glass technologies are integrated into the windshield and front triangle, door, and rear windows to improve driver visibility, gas mileage and electric driving mode mileage efficiency:
Hydrophobic coating – Fluorine coated glass causes rain drops to form into semispherical shapes for improved visibility and rain drop elimination (also used on the roof solar panel)

Anti-solar film with radio-wave transparency – Reduces the internal vehicle temperature and improves electronic device functionality

“The continued success of our conventional hybrid vehicles has laid strong groundwork for market acceptance of future advanced technologies,” said Lentz. “NS4 demonstrates Toyota’s ongoing commitment to enhancing the safety, efficiency, and convenience of future mobility for people everywhere.”
