2009 Nissan Murano
NAKANO: BACK SEAT DRIVING LATEST RESULTS OF IIHS CRASH TESTS Murano Tops Field of Midsize SUVs, 3 SUVs are Marginal ARLINGTON, VA - The best overall performer in front, side, and rear tests of nine 4-door midsize SUV models is the redesigned 2009 Nissan Murano, which earns the Top Safety Pick award. The tests were recently conducted by the Insurance Institute for Highway Safety. The Jeep Liberty, Jeep Wrangler 4-door, and Kia Sorento, all 2008 models, are the worst performers in the side test. The Liberty, also sold as the Dodge Nitro, and Wrangler earn the second lowest rating of marginal for protection in side crashes. The Sorento earns the lowest rating of poor. The Mazda CX-7 and CX-9 as well as the Mitsubishi Endeavor earn good ratings for protection in front and side crashes. All three would have won Top Safety Pick if they had good ratings for protection against neck injury in rear-end crashes. The seat/head restraint combinations in both Mazdas are rated marginal for rear crash protection. The Endeavor's is poor. Safety of SUVs is improving: In 2001 only half of the midsize models that were tested earned good ratings in the frontal offset test. In the latest evaluations, all but the Hummer H3 do, and it earns an acceptable rating. As manufacturers introduce improved designs, more SUVs are qualifying for Top Safety Pick by earning good ratings in all three tests and having electronic stability control (ESC). For the 2007 model year, the Institute added ESC as a criterion. It's a control system comprised of sensors and a microcomputer that continuously monitors how well a vehicle responds to a driver's steering input and selectively applies brakes and modulates engine power to keep the vehicle traveling along the path indicated by the steering wheel position. Institute research indicates that ESC reduces the risk of fatal single-vehicle crashes by 56 percent and fatal multiple-vehicle crashes by 32 percent. Many single-vehicle crashes involve rolling over, and this feature reduces the risk of fatal single-vehicle rollovers by 80 percent (SUVs) and 77 percent (cars). "Combined with test results released last year, consumers now have 9 midsize, moderately priced SUV models that earn our Top Safety Pick designation," says Institute senior vice president Joe Nolan. "More good news is that manufacturers have been moving quickly to add safety features like stability control and side airbags to their SUV models," Nolan adds. "All of the SUVs in this group have ESC, and all but the Wrangler have standard side airbags. Increasingly, consumers are getting the latest safety equipment without having to hunt through a list of options." Murano wins Top Safety Pick designation: The Murano has been redesigned for the 2009 model year and ESC, previously an option, now is standard equipment. This is the only SUV in the group recently tested to earn good ratings in all 3 Institute tests, and it's 1 of only 2 in this group to earn a good rating for protection against whiplash injury in rear-end crashes. Whiplash usually isn't life-threatening, but it can be debilitating and difficult to recover from. Whiplash is the most serious injury reported in about 2 million insurance claims each year, which cost at least $8.5 billion. Rear impacts are common in everyday commuter traffic. In one urban county in Virginia, 63 percent of daytime crashes on urban interstate highways in 2003 were rear impacts. "You don't know what kind of crash you're going to get into, so you want a vehicle that affords the best protection in the most common kinds of crashes," Nolan says. "The Murano is the only SUV in the group that does this." Chest protection isn't up to par in some SUVs: Head protection is important in a side crash, but so is protecting the chest and abdomen. Manufacturers can do this with additional padding in the doors or with separate side airbags that usually deploy from the side of the seat. Unlike most cars that are equipped with side airbags, some of the SUVs in this group with standard curtain airbags lack separate ones to protect the torso. Curtain airbags in the H3, Liberty, and Sorento provided good head protection, but all 3 were downgraded because forces on the driver dummy's metal ribcage indicated that rib fractures and internal organ injuries would be possible in a real-world crash of this severity. "Performance of some of these models in the side test was surprising," Nolan points out. "SUVs should have an inherent advantage in such crashes because drivers and passengers ride higher up than in cars. People often think they're safer in an SUV, but many cars perform much better in our side test than some of the SUVs in this group." Note: The Jeep Wrangler was tested without its optional combination head and torso side airbags. The Institute's policy is that when airbags are optional, the vehicle is tested without the option. A manufacturer may request a second test with the option if the automaker reimburses the Institute for the cost of the vehicle. In the case of the Wrangler, Chrysler didn't request another test. "We assume that Chrysler doesn't expect the Wrangler to perform much better, even with the optional airbags," Nolan says. Hummer isn't good in frontal crash: Nearly every vehicle the Institute tests now earns the top rating of good for frontal crash protection. This wasn't the case for the Hummer H3, which earns an acceptable rating. The H3 is 1 of only 2 midsize SUV designs the Institute has recently tested that doesn't earn a good rating in the frontal test (the other is the Chevrolet TrailBlazer). In the Institute's test, high forces were recorded on the dummy's lower right leg, indicating the likelihood of injury. Still, forces on the dummy's head and chest were low, and the vehicle's structure held up well. "Acceptable isn't a bad rating," Nolan explains. "It's just not the best protection that's available. Considering the Hummer's acceptable side rating and poor rating in the rear test, we can see that this SUV hasn't been designed with the state-of-the-art crash protection of many of its competitors." How vehicles are evaluated: The Institute's frontal crashworthiness evaluations are based on results of 40 mph frontal offset crash tests. Each vehicle's overall evaluation is based on measurements of intrusion into the occupant compartment, injury measures recorded on a Hybrid III dummy in the driver seat, and analysis of slow-motion film to assess how well the restraint system controlled dummy movement during the test. Side evaluations are based on performance in a crash test in which the side of a vehicle is struck by a barrier moving at 31 mph. The barrier represents the front end of a pickup or SUV. Ratings reflect injury measures recorded on two instrumented SID-IIs dummies, assessment of head protection countermeasures, and the vehicle's structural performance during the impact. Injury measures obtained from the two dummies, one in the driver seat and the other in the back seat behind the driver, are used to determine the likelihood that a driver and/or passenger in a similar real-world crash would sustain serious injury to various parts of the body. The movements and contacts of the dummies' heads during the test also are evaluated. Structural performance is based on measurements indicating the amount of B-pillar intrusion into the occupant compartment. Rear crash protection is rated according to a two-step procedure. Starting points for the ratings are measurements of head restraint geometry - the height of a restraint and its horizontal distance behind the back of the head of an average-size man. Seats with good or acceptable restraint geometry are tested dynamically using a dummy that measures forces on the neck. This test simulates a collision in which a stationary vehicle is struck in the rear at 20 mph. Seats without good or acceptable geometry are rated poor overall because they can't be positioned to protect many people.

NAKANO: BACK SEAT DRIVING ARE YOU CHANGING YOUR OIL TOO OFTEN? State Says Many Drivers Change Oil Too Often Remember the old adage about changing your car's oil every 3,000 miles? It was the gear head gospel, no matter what the manufacturer recommended. "It couldn't hurt," was the comeback. It turns out, it can hurt. The California Integrated Waste management Board has initiated a new state campaign urging California drivers to ignore both conventional wisdom and stick with the recommendations in the owner's manual of your vehicle. "Used oil is so much of a problem in California that if you can change your oil in less-frequent intervals, you not only save yourself money, you help save the environment," California Integrated Waste Management Board spokesman Jamie Cameron-Harley told Michael Cabanatuan of the San Francisco Chronicle. The Board is the sponsor of "The 3,000-Mile Myth" campaign and of the website, www.3000milemyth.org. The agency has the responsibility to reduce waste and keep used oil out of landfills, water bodies and groundwater. According to the Chronicle, the campaign was launched after research found that 73 percent of Californians change their oil more frequently than recommended by the manufacturers of their vehicles - most of them at 3,000 miles. Consumer Reports recently issued a statement corroborating the findings of the Board. "Although oil companies and quick-lube shops like to promote th, it's usually not necessary, said Consumers Union, publisher of Consumer Reports. "Go by the recommended oil-change schedule in your vehicle's owner's manual. Most vehicles driven under normal conditions can go 7,500 miles or more between oil changes. Some models now come with a monitoring system that alerts the driver when the oil needs changing. Depending on driving conditions, these can extend change intervals to 10,000 or 15,000 miles." "Very few people recommend changing the oil every 3,000 miles anymore, says Tom and Ray Magliozzi of NPR's Car Talk. "It's just not necessary, and the environmental cost is too high." "Oil can easily foul local ecosystems and even the drinking water supply," reports Cabanatuan. "People who change their own oil generate about 150 million gallons of used oil each year, according to the American Petroleum Institute." Cabanatuan offers some tips to protect the environment from your car's oil:
- Check your manual on how to properly change your oil and how frequently it should be done.
- Don't change your oil more often than necessary. Read the carmaker suggestions for your vehicle at www.3000milemyth.org.
- If you change your own oil, recycle both the oil and the filter. To find a recycling center, go to links.sfgate.com/ZCJP.
- Keep super-absorbent towels or kitty litter on hand to sop up any oil that is spilled.
- Keep your car properly maintained to prevent drips of oil or other fluids that could be washed into storm drains.
- Never dump anything - especially oil - in storm drains, which discharge directly to local waterways, the bay and the ocean.

NAKANO: BACK SEAT DRIVING GMC Introduces the Denali XT Hybrid Concept Truck GMC unveiled the Denali XT concept at the 2008 Chicago Auto Show. The company claims a 50-percent increase in combined fuel economy over comparable small pickup trucks when running on gasoline, while incorporating a new, muscular form in a performance-styled, hybrid sport-utility truck (SUT). The Denali XT has a unibody architecture and rear-wheel drive. It builds on the equity of the Denali line and its reputation for advanced engineering and refinement, including the first combination of GM's two-mode hybrid system with an E85 ethanol-capable engine. Denali XT's new, more efficient 4.9L version of GM's small-block V-8 features fuel-saving technologies such as direct-injection technology and Active Fuel Management. The engine is matched with GM's unique two-mode hybrid propulsion system, which is said to give the SUT exceptional fuel economy and uncompromising capability - including all-electric drive at low speeds. GMC hopes the public will fiind the Denali XT perfectly suited to a variety of active lifestyle activities, such as hauling skis and snowboards to the mountain or towing a sport jet boat to the lake. "Like all GMCs, the Denali XT is functional and capable, but it blends those traits with a more efficient, sporty driving experience," said Jim Bunnell, GMC general manager. "It is a vehicle that exemplifies GMC's engineering excellence, as well as GM's commitment to hybrid and advanced technologies." With its unibody structure, the Denali XT is lighter than conventional body-on-frame trucks, with great ride-and-handling characteristics. This design enhances fuel economy while giving the vehicle a sporty driving experience. True to its GMC Professional Grade heritage, the Denali XT is filled with technologies and features that maximize its flexibility, including a cargo space-enhancing Midgate® and height-adjustable suspension. The Denali XT's proportions are framed around a high cowl and 123.4-inch (3,134 mm) wheelbase. This enhances the vehicle's truck functionality, but packages it in an efficient, unibody architecture. Design and construction were spearheaded by Holden Design, within the Australian arm of GM's global design and engineering network. "Denali XT is about working hard, playing hard and enjoying an active lifestyle," said Bunnell. "It is the same philosophy that has helped make the GMC Acadia crossover a huge hit with consumers."
Return of the El Camino? "It is a robust yet tailored design statement that is unlike anything else on the road," said Ed Welburn, vice president, Global Design. "It has the youthful look of a custom automobile that incorporates the capability customers expect from a truck." The Denali XT's design includes a new take on GMC's iconic grille, with a prominent, four-bar element in addition to the large, red GMC logo and signature Denali background. Flared fenders accentuate the wide road stance. The stance is also enhanced when the Denali XT is lowered on its air-adjustable suspension, which creates a sleeker appearance that simultaneously improves aerodynamics. Large, bold 23-inch wheels and custom Kuhmo tires complement the Denali XT's stance. Inside, the Denali XT blends mechanical functionality with leather-trimmed comfort. Billet-metal surrounds, controls and instruments convey the cold precision of an aircraft cockpit. This is balanced by the warmth of bespoke saddle-leather trimmed seats and other contact surfaces. "The form language is smooth and structured to characterize GMC's power. The details have a deliberately contrasting mechanical aesthetic to mark GMC's engineering sophistication," said Warrack Leach, lead designer. The interior features innovative instrumentation with "floating" red-illuminated numerals backed by surface chaplets in the clusters and a large integrated vehicle interface screen. The interior illumination was supplied by Osram. The Denali XT seats four. The high-cowl vehicle architecture enables higher seating positions, allowing the couple distance between front and rear occupants to be reduced without compromising knee room. This packaging efficiency creates generous interior and cargo bed dimensions within a more compact package. Truck capability With stiffness that is greater than most conventional, body-on-frame trucks, the Denali XT's unibody structure supports a very capable truck platform. It also serves as the mounting point for a four-wheel independent suspension that gives the vehicle its performance feel on the road. The multilink front suspension features a forward-mounted steering rack and dual lower links with ball joints at the outer ends, providing sharp responses to driver input. At the rear, a four-link suspension design uses coil-over shocks and a decoupled stabilizer bar to enhance cornering control, reduce body roll and optimize longitudinal compliance. In short, it's a truck that hauls more than cargo on twisting roads. The rear cargo area is wide, deep and flat, with no suspension or wheelhouse protrusions; the cargo floor measures 55 inches long (1,397 mm) by 47.5 inches wide (1,206 mm). It all adds up to the space to haul a wide variety of lifestyle accessories. The Midgate can be lowered to extend the cargo-carrying capacity inside the vehicle. The rear seats fold flat to provide a longer floor for carrying items such as skis, surfboards or wood from the home improvement store. A fixed rear window allowed engineers to retain the vehicle's structure, reducing mass and complexity. The Denali XT has an estimated payload capacity of 1,100 pounds (499 kg) and a towing capacity of an estimated 3,500 pounds (1,587 kg). This capability is delivered through unique vehicle and powertrain integration, where the multiple modes of GM's two-mode hybrid system provide towing capability.
New 4.9L SIDI V-8 and two-mode hybrid system For the first time, GM's rear-wheel-drive two-mode hybrid transmission is paired with a smaller-displacement version of the small-block engine. The new V-8 4.9L E85-capable engine powers the Denali XT with an estimated 326 horsepower (243 kW). It uses direct-injection technology to produce the power of a larger engine, but consumes less fuel and produces lower emissions. Also, the functionality of GM's Active Fuel Management system has been expanded through the use of hybrid technologies, enhancing the cylinder-deactivating feature to further improve fuel efficiency. The Denali XT's two-mode hybrid system is partnered with the 4.9L engine and uses an electrically variable transmission to enhance fuel efficiency in city and highway driving. In city driving, all-electric propulsion is used at low speeds; on the highway, fixed-gear operation enables efficient performance even when towing a trailer. The specific characteristics of the Denali XT allowed the synergistic evolution of GM's small-block V-8 and two-mode hybrid beyond the recently introduced in GM two-mode hybrid products, such as the GMC Yukon Hybrid and Sierra Hybrid. During this optimization process, additional powertrain technologies have been integrated, including Active Thermal Management, which transfers thermal energy from one driveline component to another to improve efficiency; and a high-efficiency axle configuration, which fundamentally reduces the losses normally associated with conventional axle configurations. The integration of the advanced internal combustion engine technologies and two-mode hybrid system on the Denali XT reinforces GMC's Professional Grade position as a brand that continues to exceed customer expectations.
