Chevy recently announced the all-new redesigned Duramax 6.6-liter V8 turbodiesel engine that will be offered on the 2017 Chevy Silverado HD lineup. Offering 445 hp and a whopping 910 lb-ft of torque, the new engine is the most powerful Chevy truck engine ever.
In addition to upping its power, Chevy also reduced the engine’s noise, which improves cabin sound quality as well—Chevy says noise when idling is down 38% from previous models. Incorporating a new control system, the engine offers the same peak torque at a low rpm, but this is virtually all it has in common with the former Duramax besides its cast-iron casing.
Other upgrades to the engine include B20 biodiesel compatibility, electric control systems, better oil and coolant flow, stronger parts, and various brand-new systems that work together to provide greater performance, faster acceleration, and less engine noise even when trailering.
New solenoid-type fuel injectors boost fuel economy using high fuel pressure to atomize fuel more efficiently than ever and create a cleaner burn, reducing emissions. The turbocharger is also new, with higher maximum boost pressure for greater engine power.
One of the best things about the new Duramax engine is the improved cold weather performance. Glow plugs with engine-like starting performance can heat up in 3 seconds in extremely cold temperatures. The engine’s automatic temperature compensation is the first in its class.
The 2017 Chevy Silverado HD Duramax engine is incredibly advanced, providing more power, better fuel economy, and quieter performance than ever.
