Did you know that over half of the full-size Chevy pickups sold 20 years ago are still on the road today? With a figure like that, clearly Chevrolet has a strong reputation of making reliable trucks. So how do you improve on it without putting that reputation at risk?
Today, Chevrolet introduced Cylinder Switch Off to the Silverado line. That's right! To save on gas, the Silverado will now shut off 4 cylinders in the 5.3L V8 engine. The Silverado has a well-earned reputation as the most-dependable, longest-lasting full-size pickup. The V-8 engines under the hood have a track record no competitor can touch - developed, tested and refined over 57 years and more than 100 million engines. "Rather than adding turbochargers or multi-valve cylinder heads to increase the power of smaller engines, we chose to keep the proven capability of our larger V-* truck engines, and save fuel by switching off half of the cylinders when they aren't needed." Said Jordan Lee, Global Chief Engineer for small block engines.
A combination of simple hydraulic valves and sophisticated software switch off the cylinders when the driver doesn't need full power. When more power is needed, the system, called Active Fuel Management, seamlessly reengage the additional cylinders.
By giving customers V-8 power and capability when they need it, with enhanced fuel efficiency when they don't, Silverado offers the best EPA fuel economy estimates of any V-8 pickup, said Lee. "In fact, our 5.3L V-8 delivers EPA fuel economy estimates comparable to some competitors' V6 engines." The 2013 Silverado with the 5.3L V-8 will have an EPA estimate of 21 mpg, matching the competitors 4WD model with a more complex, less-proven boosted V-6.
