The first models and designs for automobiles were created in the 15th century by none other than Leonardo da Vinci, and the state of the global auto industry has evolved significantly since. First steam, to electric, gasoline, and today’s hybrids, the evolution of safety features in cars plays an essential role in reducing the once overwhelming number of injuries and damages resulting from auto accidents. Auto manufacturers have come a long way over the history of auto safety, paving the way for improved global safety standards.
Unfortunately, as a vehicle ages, a number of factors come into play that reduce the automobiles safety, aside from mechanical wear and tear. According to statistics, a driver is 10 times as likely to suffer fatal injuries in a collision while operating a 30-year-old vehicle versus a late model. The auto industry is continually working to improve the safety of current mechanisms, as well as developing and testing new ideas for safer vehicles. Developments in driving technology and new types of airbags have been prevalent just this year.
While the ultimate safe vehicle may be a long way off, American auto manufacturers have made significant strides in improving the overall security and protection a vehicles structure provides. Over the past 3 decades, fatal accidents in the U.S. have decreased by more than 1/5, a substantial decrease demonstrating immense progress in terms of the safety features in cars.
The need to revolutionize auto safety was not fully realized until the 1950s, when the first usable airbags were developed, among other safety mechanisms. Then, in 1970, the National Highway Traffic Safety Administration (NHTSA) was created. The organization still uses the same name today, and continues its role in promoting and effectively executing driving safety regulations throughout the U.S. Whether creating new policies or revising existing regulations (at the state and federal level), the NHTSA and the United States have been true catalysts in the history of car safety.

What if you forget to change your oil on time? Can you damage your car's engine by not changing the oil late? Do you really need to change your oil every 3,000 miles? Obviously, you should change your oil regularly, but exactly how much damage you will cause by changing the oil late? This video looks to answer this question. We'll discuss what happens to oil viscosity as it ages, and what happens to oil additives in over time.
Suspension leveling kit, rocker panel protectors and aluminum skid plates among features that elevate the confidence and capability of the Canyon AT4
DETROIT – Today, GMC announced the new 2021 GMC Canyon AT4 Off-Road Performance Edition, which enhances the Canyon AT4 and enables customers to confidently venture into rugged off-road environments, all while maintaining the premium comforts they have come to expect from GMC.
“When customers are looking for a capable off-road truck, we know that they want improved vehicle height as well as additional protection,” said GMC Marketing Director Rich Latek. “Whether it’s tackling die-hard off-road courses or embarking on a weekend adventure, the Canyon AT4 Off-Road Performance Edition provides an improved approach angle, enhanced maneuverability and underbody protection to key parts of the truck, while still delivering a premium GMC experience.”
When the Canyon AT4 debuted in January, its bolder design and premium detailing combined with confidence-inspiring capability signaled the brand’s continued commitment to offering premium, off-road capable vehicles.
Standard equipment on the Canyon AT4 includes 31-inch Goodyear Wrangler DuraTrac® tires, an off-road tuned suspension package with Advanced Hill Descent Control System and a four-wheel drive system with Eaton G80 Rear Automatic Locking Differential.
The Canyon AT4 Off-Road Performance Edition builds on this foundation to provide even more capability for drivers whether they’re venturing far off-road or navigating a trail. A suspension leveling kit and the removal of the front air dam improve the truck’s approach angle by more than 35 percent to nearly 30 degrees.
This increased approach angle is paired with rocker panel protectors and performance front and mid skid plates to provide increased off-road capability and maneuverability. The skid plates are made from sturdy, 5/32-inch aluminum and help protect the lower radiator, front differential, steering gear and oil pan. In combination with the transfer case shield standard on the Canyon AT4, the Off-Road Performance Edition offers the protection to the majority of the truck’s powertrain that off-road enthusiasts expect.
The Off-Road Performance Edition elevates the bold styling and premium refinement of the Canyon AT4 with the addition of:
Unique 17-inch Gloss Black wheels
Carbon Black AT4 logos
Gloss Black performance exhaust tip
After a day of off-road adventure, additional protection for the interior and the truck bed is provided in the form of accessory floor liners and spray-in bedliner.
The 2021 Canyon AT4 Off-Road Performance Edition will be available to order later this year. For more info, visit www.gmc.com.

V8 engines operates under the same basic principles as any other gasoline four-stroke engine. First the piston pulls in air and fuel as it moves downward, then it compresses that air and fuel as the piston moves upward. A spark plug fires, igniting the air/fuel mixture and forcing the piston downward. Finally the piston pushes out the exhaust gases on its way back up, before for the cycle repeats itself.
In a V8 engine, this cycle is happening in 8 different cylinders, at different times. Instead of multiple cylinders firing at the same time, you want them to be spread out so that power delivery is smooth. For this Chevy V8, the firing or is 1, 8, 7, 2, 6, 5, 4, 3. With 8 cylinders, there is a cylinder firing for every 90 degrees of the crankshaft rotating, which means at any point in time, there are two cylinders on the power stroke.
With regards to the valvetrain, the intake air comes from the top of the engine, and into the sides of the cylinder head. The exhaust flows to the sides of the engine, exiting the exhaust valves from the cylinder head. In this LS3 model, there is a single intake valve and a single exhaust valve, though it’s also common to see engines with two intake valves and two exhaust valves. The larger valve is the intake valve, and the smaller valve is the exhaust valve.
The pushrod valvetrain gets its name from the metal pushrods which activate the rocker arms which open up the valves. The camshaft, located in the center of the V, has lobes on it which push the push rods up, opening the appropriate valves. For a full explanation of V8 engines, check out the video!
