AS STATES MULL BANS, FORD IMPROVES SYNC TO GIVE DRIVERS SAFER ALTERNATIVES TO HAND-HELD TEXTING
MyFord Touch driver connect technology, launching on the 2011 Ford Edge, features a "Do Not Disturb" button for drivers to choose to have incoming phone calls and text messages blocked for the duration of their trip.
* Ford adds “Do Not Disturb” button to block incoming calls and texts on new MyFord Touch-equipped vehicles and proactive feature content “lock-outs” to encourage use of voice control
* In addition, Ford integrates new Bluetooth Message Access Profile (MAP) into SYNC for all MyFord Touch-equipped vehicles so more drivers can have texts read aloud to them while driving
* Research In Motion (RIM), maker of BlackBerry smartphones, plans to adopt MAP and enable SYNC audible text messaging capability to work with all new smartphones; Ford urges other phone manufacturers to follow

DEARBORN, Mich., July 8, 2010 – As the issue of texting while driving grows in prominence nationally, Ford Motor Company is expanding its SYNC technology with new features to give drivers safer alternatives to hand-held texting and keep them more focused on the road.
To help make the in-car connection safer, Ford is improving the SYNC text message readback feature and empowering drivers with a “Do Not Disturb” button so they can decide the level of connectivity and communications they want to manage while in the car. Ford is also taking the proactive step to “lock-out” capabilities that are not relevant to the task of driving while the vehicle is in motion.
“Text messaging has become the default communications method for consumers of all ages,” said John Schneider, chief engineer, Ford multimedia and infotainment engineering. “The power of SYNC voice control combined with Ford’s latest connectivity improvements will reduce the temptation to pick up the phone and take your eyes off the road, providing a safer solution for the use of mobile devices in the car.”
Ford believes drivers should keep their eyes on the road and hands on the wheel and was the first automaker to support a proposed federal ban and state-level legislation banning hand-held texting while driving. In turn, Ford also understands that drivers want to be connected to their mobile worlds while on the road, and texting continues to grow as a preferred communication method. According to a new poll from the Pew Internet and American Life Project, for example, approximately one in four (27%) American adults and driving age teens (26%) admit to texting while driving.
Ford will offer the new features on 2011 model year vehicles equipped with MyFord or MyLincoln Touch, the intuitive driver connect technology that provides drivers personalized access to information and entertainment through voice control, touch screens and familiar five-way controls mounted on the steering wheel.
Bluetooth MAP
Bluetooth is the standard technology that allows electronic devices such as a mobile phone and Ford SYNC to communicate with each other wirelessly. To improve the number of phones that can “communicate” with SYNC so the system can read aloud incoming text messages to drivers, Ford has adopted the latest Bluetooth standard – Message Access Profile (MAP).
“Today, only a small population of phones have the capability to work with the text message readback feature of SYNC,” added Schneider. “With MAP technology, even more drivers will be able to use SYNC to listen to text messages.”
Defined by the Bluetooth Special Interest Group (SIG), the MAP standard outlines a set of features and procedures used to exchange email, SMS, and MMS messages between devices. It is tailored to the automotive hands-free environment where an onboard terminal device – in this case, SYNC – takes advantage of the messaging capability of a communications device, such as a BlackBerry smartphone.
The Bluetooth SIG recommendations are considered benchmarks, but they’re not industry requirements. Ford has elected to implement the MAP to signal support for the protocol and encourage additional mobile device manufacturers to add the capability in their products.
“It’s only through acceptance of common standards industry-wide that key technologies can be adapted to the in-vehicle environment,” said Schneider. “We’re hoping to encourage the adoption of MAP so more customers – and more mobile devices – can successfully use the innovative features SYNC has to offer, helping reduce the problem of driver distraction.”
According to a 100-car study conducted by Virginia Tech Transportation Institute, driver inattention that involved looking away from the road for more than a few seconds was a factor in nearly 80 percent of accidents. By providing drivers with the ability to receive audible, hands-free texts, Ford is hoping to help drivers focus on the task of driving.
Ford is already working with Research In Motion (RIM) and supports the company’s intention to begin implementing it in all new BlackBerry smartphones.
“RIM plans to implement MAP on BlackBerry smartphones moving forward and we are pleased to work with Ford in an effort to foster industry-wide adoption and standardization,” said Andrew Bocking, Vice President, Handheld Software Product Management at Research In Motion.
“Do Not Disturb” and locked features
Ford has also proactively designed the MyFord and MyLincoln Touch driver connect system to give drivers more control of how they manage communications while in the car. Screens can be personalized to display information relevant to an individual driver using a simple button click, voice command or touch-screen tap.
The new 2011 Ford Edge and Lincoln MKX will be first to offer the “Do Not Disturb” button. This handy feature blocks incoming phone calls or text messages from a Bluetooth-enabled mobile phone paired with SYNC; diverting calls into voicemail and saving text messages on the device for viewing later. But unlike turning the phone off, drivers can still make voice-activated outgoing phone calls, if they so decide, and the SYNC 911 Assist feature can make a call to 911 in case of emergency.
In addition, Ford continues to limit access to a variety of communication features while the vehicle is in motion, thus encouraging drivers to use voice commands if they wish to access the function.
Ford is also taking the proactive step of locking out or limiting content and capabilities of MyFord Touch that are not related to the task of driving when the vehicle is in motion, for instance:
* Screens with information not intended to be used by the driver while driving such as point-of-interest reviews and ratings plus SIRIUS Travel Link sports scores, movie listings, and ski conditions
* Any action that requires typing on a keypad (e.g. typing a navigation destination, editing information)
* Limiting lists of navigation and phone choices that the user can view to fewer entries (e.g. phone contacts, recent phone call entries)
Specific functions that are locked out when the vehicle is in motion:
* Cell Phone
o Pairing a Bluetooth-capable phone
o Manually adding individual contacts into the Phonebook
o Viewing received text messages on screen
* WiFi Connectivity
o Web browsing on the vehicle screen
* Video/Photos/Graphics
o Playing video
o Album cover art and Phonebook photo browsing
o Editing photos
o Editing the screen’s wallpaper or adding a new one
* Navigation
o Destination entry by touchscreen keyboard input (voice entry is permissible)

MUSTANG V-6 AVERAGES 48.5 MPG; RUNS 1,457 LAPS AT BRISTOL ON A SINGLE TANK OF GAS
* The 2011 Ford Mustang V-6 sets a new record by averaging 48.5 mpg on a track while completing 1,457 laps with an average speed of 43.9 mph
* Mustang is powered by a new 3.7-liter V-6 engine that uses advanced engineering and technology to deliver great performance and fuel economy
* More than 51,000 entries were received for the Mustang 1,000 Lap Challenge with 22 entries guessing the winning number of laps
* A team of five drivers, including four Ford Mustang engineers and Ford NASCAR
star David Ragan, drove the Mustang during its record run
Mustang 1,000 Lap Challenge
BRISTOL, TN., June 24, 2010 – The 2011 Ford Mustang, which made history when it became the first car ever to deliver more than 30 mpg and 305 horsepower, has set a new record by running 1,457 laps at Bristol Motor Speedway while averaging 48.5 mpg.
The Mustang 1,000 Lap Challenge was designed to demonstrate that a stock production Mustang V-6 could run 1,000 laps and 533 miles on a single of tank of fuel. With the aid of fuel efficient driving techniques by Ford engineers, the Mustang far surpassed its goal of 1,000 laps.
“To see a Mustang post average fuel economy of 48.5 mpg while running at Bristol is impressive,” said Dave Pericak, Mustang chief engineer. “The new V-6 engine along with the advanced six-speed transmission in the car is a key element in delivering both fuel economy and performance for Mustang.”
Ford is committed to being a fuel economy leader in every segment it competes in and Mustang’s leads in its class along with other Ford fuel economy leaders like the Ford Fiesta, Fusion Hybrid and new Lincoln MKZ Hybrid, America’s most fuel efficient luxury sedan.
The Challenge team, which included NASCAR star David Ragan and four Ford Mustang engineers, completed the challenge in 17 hours and 40 minutes, showing off the 2011 Mustang V-6’s class-leading fuel economy by averaging 48.5 mpg over the course of the 776.5 miles logged during the Challenge. That distance is more than the two complete NASCAR Sprint Cup events that take place in Bristol every year.
Ragan pushed the Mustang past the 1,000-lap mark at 7:26 p.m., 12 hours and 26 minutes into the Challenge, but the car wasn’t close to being out of fuel. Mustang engineer Seong Park was behind the wheel when it finally came to a halt (on the backstretch) of the famed NASCAR track at 12:41 a.m. local time.
Other Mustang Challenge team drivers included Tom Barnes, Jonathan Mehl and Carl Ek, who along with Park, rotated through one-hour driving stints during the event, which took place at the world’s fastest half-mile track.
“When we hit 1,000 laps we still had a quarter of a tank of gas left,” said David Ragan, driver of the No. 6 UPS Ford Fusion for Roush Fenway Racing, and the man who drove the 2011 V-6 Mustang past the 1,000 lap mark. “The last driving stint before I passed 1,000 laps I was averaging 43.7 miles a gallon and that is unbelievable. These guys have run the distance of more than two Sprint Cup races at Bristol and they still have fuel left. Congratulations to everyone behind the Mustang and to everyone at Ford, because this 2011 Mustang V-6 is really something special.”
A team of Ford engineers prepared for the challenge by implementing fuel efficient driving tips like minimizing the use of air conditioning, steady and consistent driving, avoiding sudden stops/starts and by keeping the RPMs low. The engine in the Mustang is powered by a lightweight, all-aluminum 3.7-liter dual-overhead-cam (DOHC) V-6 engine that uses advanced engineering to deliver its combination of power and economy. Twin independent variable camshaft timing (Ti-VCT) adjusts the valve train in microseconds depending on driver inputs, further contributing to the engine’s overall efficiency. The Mustang used in the challenge is a stock production vehicle that can be purchased through a Ford dealer.
“This is beyond our wildest dreams,” said Tom Barnes, the lead engineer for the Ford Mustang 1,000 Lap Challenge. “There have been a lot of people who have done a lot of things in preparing this 2011 Mustang V-6 to run the Mustang 1,000 Lap Challenge and have the success we have had today. It was great when we went past the 1,000 lap mark with David, but nobody could ever imagine that we still had five hours ahead of us. This is a fantastic feeling and it shows again what a great car the 2011 Mustang V-6 is.”
More than 51,000 consumers registered their guesses for the event at www.mustang1000lapchallenge.com. One lucky consumer that correctly guessed 1,457 laps will be randomly drawn from all correct entries and will win their own 2011 Mustang V-6.

2011 FORD EXPLORER WITH ECOBOOST LEADS SEGMENT; AT LEAST 30 PERCENT BETTER FUEL ECONOMY
* All-new Ford Explorer SUV offers best-in-class fuel economy with technologically advanced powertrains featuring multiple enhancements to improve mechanical efficiency
* Explorer offers an optional 2.0-liter EcoBoost™ I-4 engine delivering V6 power with four-cylinder fuel efficiency
* Electric power-assisted steering, battery management, fast engine warm-up and the first North American Ford application of a variable-displacement air conditioning compressor all combine to improve drivability, increase efficiency and save fuel.
DEARBORN, Mich., July 19, 2010 – The Ford Explorer has been reinvented to shatter long-held myths about SUV fuel efficiency and performance.
The 2011 model equipped with an optional 2.0-liter EcoBoost™ I-4 engine will be the new class leader in the mid-size SUV segment, achieving at least a 30 percent increase in fuel efficiency compared with the current V-6-powered Explorer.
“The all-new Explorer will give a huge universe of existing and prospective customers the capability they expect and the luxury and convenience they want, all combined with the fuel economy they need,” said Mark Fields, Ford president of The Americas.
The new Explorer, due in Ford showrooms later this year, has added comfort and convenience features, while overall vehicle weight is reduced compared to the previous model. Extensive use of lighter and stronger high-strength steels such as boron add durability while saving weight. An aluminum hood is used, while a one-piece composite front bolster – the radiator support between engine and grille – is 65 percent lighter. Lighter weight equates to fuel and money saved.
Sophisticated engine controls and advanced technologies are key contributors to the Explorer’s improved fuel economy. Electric power-assisted steering, battery management, fast engine warm-up and aggressive deceleration fuel shutoff all combine to improve drive dynamics and save fuel. Explorer also features the first North American Ford application of a variable-displacement air conditioning compressor that reduces parasitic engine drag.
See how the all-new Explorer is being put to the test in a series of on- and off-road tests designed to drive quality and fuel economy improvements.
Powertrain advancements like twin independent variable camshaft timing and six-speed automatic transmissions help Explorer deliver responsive performance when needed combined with low-rpm efficiency when cruising.
SUV buyers placing highest priority on fuel economy can choose the available EcoBoost I-4. Delivering the power of a normally aspirated V6, this advanced engine pairs a turbocharger with direct gasoline injection to provide SUV buyers with projected class-leading fuel economy – pending EPA certification – with no compromise in performance.
Finally, all of these fuel economy enhancements are wrapped in a smooth, distinctive Explorer design that was extensively refined in wind tunnel testing. Designers and aerodynamicists collaborated to reshape sideview mirrors and harmonize the front air dam with the rear liftgate spoiler to significantly increase fuel efficiency on the highway. Reduced wind noise at speed is an incremental benefit.
“Explorer owners told us they want capability with convenience, and improved fuel economy without compromised performance,” Fields said. “We believe we’ve hit the mark with the next-generation Explorer. It has the potential to change perceptions of what a modern SUV is all about.”

Can Automatic Car Washes Damage Your Car?
Automatic/drive-through car washes are more popular than ever because they save time and hassle.
But are automatic car washes safe for your car? In fact, in many instances, they are the "safest" course of action for many car owners who want to keep their car clean.
In fact, automatic car washes can be safer for your car's finish than washing your car yourself because do-it-yourselfers sometimes don't use enough water to safely remove dirt; or they wash the car in direct sunlight -- which can burn spots in the paint. Or they use the wrong type of soap -- such as dishwashing detergent, which removes protective wax and leaves a chalky residue on the finish. Or any one of several common mistakes can end up doing more harm than good.
Cars by the numbers:
3 Most Popular Muscle Cars6 Cheap Cars with Great Gas Mileage10 Fastest Sports CarsKeeping your car clean and the finish looking good can also mean higher resale value when it comes time to get a new car. All else being equal, a car with faded paint and a dingy overall look sells for 10-20 percent less than an otherwise identical vehicle that just looks nicer.
So how often should you have your vehicle washed? That depends on how quickly it gets dirty -- and how dirty it gets. For some cars, once a month or so is sufficient -- especially if the car is lightly used and kept in a garage. But some cars will need a bath more often -- especially those that are parked outdoors where they're exposed to bird droppings, tree sap and so on, or driven in areas with very long/severe winters, where the roads are salted when it snows.
Here are a few important things to keep in mind when it comes to automatic car washes:
Be sure it's "brushless" -- Some older car washes still use abrasive brushes (instead of cloth), which can leave small scratches in a car's finish. On older cars with so-called "single stage" paint jobs, light scratches could usually be buffed out; but all modern cars use a "base/clear" system with a thin, transparent layer of clear coat on top of the underlying color coat to provide the shine. Once the thin clear coat is damaged, often the only way to restore the shine is to repaint the damaged area.
Another safe bet is "touchless" car washes that use only high-pressure water jets and detergents to clean the car -- without physically touching it at all. There is virtually no chance of your vehicle suffering any cosmetic damage this way. Some areas have "self-service" coin-operated hand washes, which are great for spraying away heavy dirt buildup. You'll usually need to bring your own bucket, wash cloth/sponge and dry towels, though.
Watch out for the after-wash wipe-down -- Most drive-through washes use a strong jet of heated air to force excess water off after the car goes through the wash. Many full-service car washes will then have you drive the car (or drive it for you, in some cases) away from the wash area to be hand-wiped by attendants. This is usually OK -- provided the attendants are using fresh, clean (and soft) towels to do so. Be alert on busy days, when lots of other cars have gone ahead of you. If you see the attendants using obviously dirty old rags to wipe the car down, you should say "thanks, but no thanks" -- and drive away wet. Dirt and other abrasives in the rags can scratch the finish just like sandpaper. Simply driving away from the wash and letting air flow over the car to dry any remaining water won't hurt anything -- and is the best guarantee of a no-damage experience. Any lingering streaks can easily be cleaned up at home yourself using readily available spray cleaners designed for just this purpose. (Honda Pro Spray Cleaner & Polish is excellent for this; it also provides UV protection and easily and safely cleans off bugs, tar and road grime, etc. without water.)
Hold off on the extras -- A "works" car wash can cost twice as much as the basic wash, but you may not be getting twice the wash for your money. Undercarriage rustproofing, for example, is of dubious value. Effective rustproofing is applied to brand-new metal, in order to seal it from contact with external corrosives such as road salt. Most new cars are extensively rustproofed at the factory during the assembly process; further "treatment" is superfluous -- and a money-waster.
On the other hand, if the wash offers an undercarriage bath, it may be worth the additional cost. Jets of water sprayed directly underneath the car can break loose accumulated crud that would be difficult (and unpleasant) to try to remove yourself using a garden hose. It's also important that underbody drainage holes not be obstructed by mud and other buildup; accumulated moisture can accelerate rust or (in the case of the air conditioning system) lead to the formation of mold in the system. The undercarriage bath should help keep those drain holes clear.
Do, however, think twice about spray-on wax. This typically adds at least a couple bucks to the cost of the wash and while it doesn't hurt anything, it's no substitute for hand-applied polish/wax. Spray-on "wax" may provide a short-term gloss enhancement, but doesn't protect against UV sun damage the way hand-applied wax does. Ditto the cost of having an attendant spray Armor All (or a similar protectant) on your tires to make them shiny. The cost for this extra can be equivalent to the cost of buying an entire bottle of the stuff on your own.
Wheel and tire cleaning is an exception; the heavy-duty cleaners used by the car wash do a great job of removing baked-on brake dust, etc., that can otherwise be a real chore to clean on your own, using over-the-counter cleaners, a hand brush and a hose. It's especially important to keep aluminum alloy wheels clean; brake dust can eventually permanently stain them if it's not regularly cleaned away.
Finally:
Make sure your car's OK before you leave -- While many car washes will have a disclaimer posted that they are "not responsible for any damages that may occur" as a result of running your car through their wash, that doesn't mean you should automatically absolve them of any damage their equipment or personnel may have caused. If you notice something, ask to see the manager and point it out to him; whether "legally liable" or not, he may offer to fix the problem in the interest of customer relations. And even if he does not, you can still pursue the matter with a higher-up (such as the company headquarters, if the wash is a franchise, as many associated with big-name gas stations often are). If you have a cell phone with a camera, use it to take a photo of the damage in order to support your claim. And it ought to go without saying that you should never leave your purse or other valuables in the car if you use a wash where an attendant will have access to the vehicle's interior.
