Why your next pickup should be a GM
Oddly enough, out of all of the research done into hybrid technology GM has been forward thinking enough to make theirs are not only affordable, but ingenious as well. They now offer both the Sierra and the Silverado pickups as hybrids country wide. Using a technology not formerly seen in hybrids, GM attempted to not only lower emissions in their pickups, but to make them handier as well. Affordable technologyGM wanted to make a hybrid truck that was too well priced to turn down, the major complaint of the hybrid models is high price tag which counteracts the gas mileage benefits. In response to this GM produced their pick up hybrids to cost only $1500.00-$2500.00 more than its gas guzzling brothers, saved with tax cuts at the pump within the first few years of ownership. Especially if you consider that the hybrids produce a 10% improvement in fuel economy, all without sacrificing any power. Both the Sierra and Silverado offer the same 245 horsepower V8 engine, and can tow up to 7,700 pounds. If you consider that pickup truck drivers are not sacrificing any power and when sitting stopped in traffic it emits very limited pollution for their size. Hybrid systemGM employs what they call a “flywheel alternator starter hybrid system” which uses a compact electric motor incorporated between the engine and the transmission. This electric engine runs the truck when it is slowing or idling at a standstill. They calibrate the flywheel alternator system to turn off the engine more frequently than even those systems used in most smaller hybrid models. Eliminating much of the pollution caused by slow moving traffic in high volume. Now your work truck can double as a generatorBoth the Sierra and the Silverado boost four 120-volt, 20 amp three-prong outlets which can be used to provide power for electrical tools and electronics. This eliminates any need for a gassy generator spewing fumes into the air at a work site. The truck must be running, but utilizing it’s electric engine allows it to run virtually emission free. GM reports that their hybrid trucks can continue to pump out power for up to 32 hours non-stop before needing to refuel. Aimed specifically at contractors, whose need to access abundant sources of energy and drive long miles to job sites fuel this intelligent new take on a work truck. Testers reportThe power source for tools was not quite as juicy as GM would have you think, however the idea is a brilliant one. No doubt in a few generations they will have nailed down this imperfection in an already forward thinking vehicle. Although the gas mileage is a tad better overall, it borders on insignificant. Which again is certain to be addressed and updated in generations to come. Reviewers say that the feel of the engine cutting out as you hit ten miles an hour is a bit disconcerting, and takes some getting used to, but its pollution saving benefits far outweigh that small detail. Every accessory on the truck is electrical, so the gas engine only runs when it is needed to for its sole purpose, to accelerate the vehicle. Overall appealThe brilliance behind the ideas developed for these pickup truck models is really what drives them at this point. Fine tuning is necessary of any piece of equipment and GM has been making pick up trucks for a long time. They will continue to address the issues and refine the existing good points, driving the hybrid market to continue to bring us new and innovative ideas. <b>About the Author:</b> My name is Paige Filler and I'm a creative writer with a love of all things that go vroom.

Tire Safety: How Old Is Too Old?
When thinking about tire safety, it is important to consider two things: age and use. Vehicles driven daily are typically driven 15,000 miles a year. But there are situations where cars put on even fewer miles. This includes: being driven only on the weekends, never driving in the rain, show cars, and cars that are stored for extended periods of time. So, some tires on these types of cars put on less than 100,000. But it doesn t mean that they are safe tires. Tires deteriorate over time and can age out wear out before they wear out. In a statement from the British Rubber Manufacturers Association (BRMA) issued on June 5, 2001 regarding the age of tires they state, “BRMA members strongly recommend that unused tires should not be put into service if they are over 6 years old and that all tires should be replaced 10 years from the date of their manufacture.” Tire age can be accelerated by a variety of environmental factors, such as sunlight exposure and coastal climates. Poor storage and infrequent use of your vehicle are other things that can accelerate tire age. If you keep your tires in ideal conditions, the tire age can go as high as 10 years from its manufacture date. But ideal conditions are the exception rather than the rule. And the worst part is that you cannot tell the safety of an old tire just by looking at it since there are no conclusive tests for the safety of tires without destroying the tire itself! Due to this, some European car manufacturers of high performance sports cars, coupes and sedans have hedged their bets, stating in their owners manuals that the tire age should reach no higher than 6 years. How Better Rubber Makes Tires That Are Safe There have been a lot of changes in rubber compounds since Charles Goodyear discovered how to cure rubber when he baked a combination of natural rubber and sulfur on his family s kitchen stove. Thus, he would convert an unappreciated raw material into many useful products. Goodyear cross-linked sulfur with polymers that, when exposed to heat, would help make rubber durable and at the same time maintain its elasticity. The main focus of new research has been finding tire age inhibitors. Sulfur molecules are one such tire age inhibitor that is reactivated every time they are exposed to heat, making the rubber harder. Nowadays, rubber in tires has oil in it that tends to migrate into the tires under tread/casing and evaporate into the air. In the process of this, the tire compound releases oil and gets harder. If you can t quite visualize this, go into any tire store and take a big whiff. You ll smell the oil there. Before curing, most tires are coated with a mold release agent that is makes it easier to remove from their mold after curing. If it s a little hard to visualize, think about spraying Pam on a fry pan before pouring on the batter for pancakes. This increases the safety of tires because some of the mold release agent gets cooked onto the surface of the cured tire, which prevents all the oil from evaporating. What Is The Right Tire Age? In most cases, most street tires are good for 6-8 years if maintained properly. Don t forget though that this includes the time the tires spent from the manufacturer s plant to the dealer to you. So, keep this in mind when you are determining tire age. Most tires get to you anywhere between 3-6 months. Some stay longer with the tire manufacturer, but generally all tires that go on your car are less than a year old. So, you should not get an old tire from any tire manufacturer. Which Tires Last Longest? If you want to buy a tire based on how long it will last, you have to consider thread compound. The more aggressive its compound the shorter tire life. Below is a list of tires from longest-lasting to shortest-lasting: Max Performance Ultra High Performance tires DOT-legal competition tires Bottom line: if you want to avoid safe tire issues go with tires that last long and properly maintain them.Bob Martin says Don t buy any new tires until you take a serious look at this today http://www.discount-tires-online.com/TireRatings/tire-rating-guide.htm This article is a copyrighted work and does not come with reprint or resale rights and may not be altered or changed in any way including the resource box.
