Following a slight delay, Chevrolet has introduced their new diesel engine for the 2020 Silverado 1500.
Set to be offered on LT, RST, LTZ and High Country variants, the 3.0-liter Duramax turbodiesel inline-six produces 277 hp (207 kW / 281 PS) and 460 lb-ft (623 Nm) of torque. It is connected to a ten-speed automatic transmission which features a “centrifugal pendulum absorber torque converter” that promises to reduce vibrations and improve smoothness.
The engine delivers 95 percent of its peak torque at just 1,250 rpm and Chevrolet says that is sustained up to 3,000 rpm. The model also utilizes exhaust braking to help slow the vehicle which allows for fewer brake applications when using Tow Haul mode.
Since the truck will likely be popular in colder climates, engineers outfitted it with ceramic glow plugs that reduce heat-up times and allow for a quicker cold start. More importantly, owners don’t have to worry about using an engine block heater until temperatures dip to -22° F (-30° C).
Chevrolet didn’t mention fuel economy figures, but the engine has stop/start technology which helps to conserve fuel by shutting off the engine when the truck comes to a stop. The engine is then automatically restarted as soon as the driver takes their foot off the brake.
Diesel engines typically carry a hefty premium, but the 3.0-liter Duramax turbodiesel will be priced identically to the optional 6.2-liter petrol V8. As a result, the engine costs $2,495 more than the 5.3-liter V8 and $3,890 more than the turbocharged 2.7-liter four-cylinder.
While the Silverado is a bit late to the diesel party, the Duramax is more powerful than the 3.0-liter Power Stroke V6 diesel in the Ford F-150. That engine produces 250 hp (186 kW / 253 PS) and 440 lb-ft (596 Nm) of torque.
The truck could also be more powerful than the upcoming Ram 1500 EcoDiesel which is expected to use the same 3.0-liter V6 engine as the Jeep Gladiator and Wrangler. In those models, it develops 260 hp (194 kW / 264 PS) and 442 lb-ft (599 Nm) of torque.
