Nissan Concept Car to Showcase Anti Drunk-Driving Technology

Shift knob alcohol odor sensor

Nissan Motor Co., Ltd. has revealed a new concept car featuring multiple preventative features designed to help reduce drunk driving. Presently integrated on-board a production model Nissan Fuga sedan, the various technologies are designed to detect the driver's state of sobriety and to activate a range of preventive measures including immobilization of the vehicle.


Alcohol Odor Sensors

1. A hi-sensitivity alcohol odor sensor is built into the transmission shift knob, which is able to detect the presence of alcohol in the perspiration of the driver's palm as he or she attempts to start driving. When the alcohol-level detected is above the pre-determined threshold, the system automatically locks the transmission, immobilizing the car. A “drunk driving” voice alert is also issued via the car navigation system.
2. Additional alcohol odor sensors are also incorporated into the driver’s and passenger seats to detect the presence of alcohol in the air inside the vehicle cabin. When alcohol is detected, the system issues both a voice alert and a message alert on the navigation system monitor.

Facial Recognition System

A camera is mounted on the instrument cluster facing the driver to monitor the driver’s face. The system is calibrated to monitor the driver's state of consciousness through the blinking of the eyes.

When the system detects signs of drowsiness, a voice and message alert is triggered via the navigation system. Additionally, a seat-belt mechanism is activated which tightens around the driver to gain his or her immediate attention.

Driving Behavior

By constantly monitoring the operational behavior of the vehicle (e.g. sensing if the vehicle is veering out of its driving lane), the system can identify signs of inattentiveness or distraction in the driver. When the system detects such behavior, voice and message alerts are issued via the navigation system. The seat-belt alert mechanism is also activated, tightening around the driver to gain immediate attention.

System Configuration

This concept car was developed as an exploratory platform to showcase breakthrough technologies that could potentially be applied in future production cars, part of an ongoing program from Nissan contributing towards the prevention of drunk driving.

Nissan has already launched and is developing several initiatives to help prevent drunk driving. In June, the company introduced the “drunk driving” message alert on its navigation system. In July, Nissan also began testing of a new on-board breathalyzer system in cooperation with several local government authorities, where an interlock mechanism will immobilize the vehicle if the driver’s breath indicates the presence of alcohol above a specified level.

Nissan is taking holistic approach towards safety that extends beyond the technology built into its vehicles. To achieve a “safe driving environment”, Nissan has embarked on the Intelligent Transport System Project (ITS) in Kanagawa Prefecture – aimed at helping to reduce road accidents via the analysis of traffic data collected from on-the-road vehicles and traffic beacons. In Japan, the company’s safety vision is to halve the number of traffic fatalities or serious injuries involving Nissan vehicles by 2015 compared with the level in 1995.

2008 Saab 9-7X Aero Takes Off

Saab's Limited Edition SUV Offers Jet-Like Performance

2008 Saab 9-7X Aero

Saab takes SUV-performance to a new altitude as it announces the Aero performance version of the 2008 Saab 9-7X today. The limited edition Saab 9-7X Aero will make its way to dealer showrooms early this autumn.

The 2008 Saab 9-7X brings unique Saab brand characteristics to the midsize SUV segment, including sophisticated styling inside and out, premium design features, and the sporty and spirited performance inherent to Saab vehicles. Since its debut two years ago, more than 12,000 have been sold in the U.S. and Canada. For 2008, Saab adds the Aero model - the symbol of serious Saab performance - to the 9-7X lineup. The limited edition 9-7X Aero takes Saab's interpretation on the midsize SUV to an entirely new level accelerating the performance aspect of the sophisticated vehicle with a 6.0L V-8, 20-inch wheels and tires, unique paint and custom interior accouterments.

"The Saab 9-7X Aero is one great SUV to pilot," Shannon said. "We are excited to offer enthusiastic drivers an increased level of performance with the Aero, a symbol of Saab performance, in the midsize SUV segment."

The new Saab 9-7X Aero features a powerful, 6.0L small-block V-8 delivering 390 horsepower (295 kW) and 395 lb.-ft. (542 Nm) of torque. With 0-60 mph acceleration under six seconds, the 9-7X Aero is a treat for those who are actively passionate about the driving experience.

The Saab 9-7X Aero will be easy to spot as it wears a paint color all its own: Carbon Flash Metallic. The charcoal metallic paint nicely enhances the SUV's clean lines. Specific to the 9-7X Aero are 20-inch polished, aluminum wheels wrapped with P255/50R20 V-speed-rated performance tires that provide the optimum balance between ride and handling. Complementing the refined and driver-oriented cockpit-inspired interior are "Aero" embroidered leather seats and embossed floor mats.

Under the hood of the Saab 9-7X Aero is the LS2 6.0L V-8 with a cold air induction package, rated at 390 horsepower (295 kW)* at 6,000 rpm and 395 lb.-ft. of torque (542 Nm)* at 4,000 rpm. The LS2 6.0L is based on the small-block V-8 architecture and delivers excellent down-low torque for strong off-the-line performance. Torque is inherent to the engine's cam-in-block design, which features large 4.00-inch-diameter (101,6 mm) bores and a 3.62-inch (92 mm) stroke. Response is crisp and immediate, thanks to the electronically controlled throttle.

Unique to the Saab 9-7X Aero's version of the engine is a composite intake manifold adapted to the LS2 engine to help produce balanced torque and horsepower. Maximum towing capacity on 9-7X Aero model is 6,600 pounds (2994 kg).

Like all Saabs, the new Saab 9-7X Aero is driver-focused, with a lowered chassis tuned and tested to deliver responsive, balanced handling. Corner control and body roll control are improved with front stabilizer bars that are approximately 10 percent larger in diameter. Additional strength is provided by a heavy-duty rear axle with limited-slip differential.

With a four-wheel disc braking system enhanced with larger, 12.8-inch (325 mm) front disc rotors and iron twin-piston calipers, it's not difficult to put a stop to things in the more powerful 9-7X Aero. The heavy-duty iron calipers are stiff and retain their shape under high-pressure / high-heat braking conditions, providing a more linear feel and reduced pedal travel in high-energy stops. The brake pads use high-performance linings for strong fade resistance.

ABS and automatic all-wheel-drive are standard on all Saab 9-7X models as well as the StabiliTrak electronic stability control system that provides confident, sure-footed travel. The performance-oriented all-wheel-drive system delivers impressive on-road grip and enhanced "launch" feel. The always-engaged system uses a Torsen center differential to split torque between the front and rear wheels. It is a torque-bias system that detects low traction at one axle and directs more torque to the other when needed.

Like all Saab 9-7X models, the Aero model represents a terrific value with a high-level of standard equipment. In fact, the Saab 9-7X boasts the most standard features in its class while offering a very competitive starting price at $39,935. The limited edition Saab 9-7X Aero will start at $45,690, which includes a $745 destination fee and will begin arriving at dealerships this fall.

Saab is a division of General Motors Corp. Saab Automobile USA is the importer and/or distributor of Saab 9-3, Saab 9-5 and Saab 9-7X automobiles for Saab Automobile AB, Sweden. In 2007, Saab celebrates 60 years since first being introduced to the automotive scene as the vision-turned-reality of 16 aircraft engineers.
