As we once again find ourselves situated at the end of another year in Knoxville, it's one of those moments when we can take a look back at the production and history of the brand we love. Torque is the actual force that an engine generates while it is twisting, and over the last century, Chevy has provided durable trucks with powerful torque for over 85 million new customers. Driving off the lot with a new truck that can help you haul whatever you need to, as well as conquering new terrain always can make your New Year that much better, and here at West Chevy, we have a large variety to choose from.
Things have progressed massively since the very first one-ton model from 1918, which had a 2.8-liter inline 4-cylinder engine, and only provided a meek 45 lb-ft of torque. There's a close relative of this very same engine in the form of a 2.45-liter that is now situated in the Colorado, that is now rated at 191 lb-ft of torque, or 76 lb-ft per liter. This is a very hefty 480 percent increase in power, which shows just how far engineering and development have progressed in the truck world.
Dominating the collection of various trucks in terms of power is the Silverado 3500 HD, which tops the scale at a full ton, and houses an available Duramax 6.6-liter Turbo Diesel V-8. High-tech advances such as turbocharging and direct injection are other integral weapons in the fight to provide more torque per liter, which means every brand-new owner can haul that much more cargo in the long run.
The First Stovebelt Six was released in 1929, and was a prime example of grade A truck construction. It was a great accomplishment, in that it forever changed the work-load rating from 1 ton to 1.5 tons. The Stovebelt Six nickname came from the type of external fasteners it uses that are similar to the bolts on wood-burning stoves. These fasteners quickly became symbols of how durable the engine is, and from this design stemmed several more generations of Chevy overhead-valve straight-six engines. This engine put to use a forged steel crankshaft with three bearings and cast-iron pistons, and the 194 was shared with GMC and Chevy truck for use in 1935, and 1936.
The first small-block V-8 from Chevy was introduced in 1955, it subsequently was the very first overhead-valve V-8 engine. During later days, it was known simply as the “Small Block”, and was outfitted with a 265-cubic inch engine that was capable of producing 238 lb-ft of torque. It was a model that later evolved into one of the industry's longest-standing engine offerings. A decade after the small block was introduced, the big block engine family made its debut, which was a milestone as far as performance level for all gas-powered trucks. It is actually still in existence, and is situated in the fifth generation of Chevy trucks for the 2018 year.
During the 1980's, Chevy made the choice to exchange high compression ratings for boosted levels of technology. Electronic fuel injection was developed, resulting in the possibility of higher efficiency numbers. Torque in the small-block engine was boosted to 300 lb-ft during 1987. A few years later, the 5.7-liter Vortec Small-block provided a 10% increase in torque, a substantial gain after so much progress had already been made. Variable valve timing and direct injection are two of the technologies that have really been able to boost the performance factor of trucks, and change their output for the better. In the current Silverado 1500, a rating of 460 lb-ft has been accomplished with the use of these technological advances.
Duramax Technology first came about during 2001 for Chevys HD trucks, and was the beginning of a very new era of the highest in capability. The second-generation available in the 2018 Silverado HD lineup boasts an impressive output of 910 lb-ft of torque.Car and Driver was on the scene to record a 0-60 mph time for a very quick 6.2 seconds completed by a Silverado powered by Duramax, which was the quickest time ever laid down for an HD truck. The latest version is the L5P, which was introduced in 2017, and the most powerful diesel engine in existence. It is so powerful and capable, that TFL Truck has on record a climb up the Eisenhower-grade in Colorado in 10:16.99 minutes, about 12 seconds faster than the nearest one-ton competitor!
