Reliable Engines
When it comes to the engine lineup found in the 2017 Silverado, you’ll be happy to know it’s a truly legendary lineup. The EcoTec3 engines use three fuel-saving techniques: Active Fuel Management, Direct Injection, and Continuously Variable Valve Timing. The engines in question ar a 4.3-liter V6, a 5.3-liter V8, and a 6.2-liter V8.
4.3-liter V6
This engine produces 285 horsepower and 305 lb.- ft. of torque, standard for a V6. Thanks to fuel-saving technology, it’s able to get up to 18 mpg city/24 mpg highway, and can tow up to 7,600 pounds when properly equipped.
5.3-liter V8
Step up to the 5.3-liter EcoTec3, and you’ll be seeing 355 horsepower and 383 lb.-ft. of torque. While still returning a fuel-efficiency rating of 16 mpg city/23 mpg highway, the most impressive aspect of this engine is that it’s able to tow a whopping 11,100 pounds.
6.2-liter V8
The strongest engine in the lineup is a 6.2-liter V8, which is rated for 420 horsepower and 460 lb.-ft. of torque.
This powertrain returns up to 15 mpg city/21 mpg highway. That low fuel economy rating is expected, simply because of the size of the engine and weight of the truck. But, that increased horsepower and torque gives it a tow rating of 12,500 pounds, surely more than enough for whatever you’d need to tow with a truck of this caliber.
Best-in-Class Ratings for All Three Engines
What’s so special about Chevy’s engines? Apart from having fuel-saving technology on all three of its engines, all three also win a best-in-class rating for a particular corresponding category. The 4.3-liter gets best-in-class torque for a V6 engine, the 5.3-liter gets a best-in-class V8 fuel-efficiency rating, and the 6.2-liter gets a best-in-class tow rating.
For the consumer, this means that whatever you’re looking to get out of your truck — regardless of engine size — you’re getting the best on the market.
