The automotive media has had the chance to sample the 2020 Chevrolet Silverado diesel before it launches later this year.
As you likely already know, the Duramax LM2 3.0-liter inline-six turbodiesel engine for the Silverado was not launched for the 2019 model year, with the 2020 truck being the first to feature the optional mill. It will carry the same price premium as the 6.2-liter V8 when the 2020 Chevrolet Silverado order books open in the near future, but is it worth plunking down the extra cash?
If Car and Driver is to be believed, it just may be worth splurging for. The publication had the chance to drive a 2020 Chevrolet Silverado diesel in Oregon and came away saying the engine was “refined and quiet.” They were also impressed with the observed fuel economy, which stretched to 40.6 MPG on the highway – although to get this figure the writer had to shut the A/C off, fold in the side mirrors and use the manual shifter to change gears early.
Motor Trend drove the truck in a more regular fashion and observed an average of 28 MPG after both highway driving and some stop-and-go city driving. Motor Trend also said it was impressed with the 270 horsepower engine’s grunt, saying it provides “a healthy surge of torque every time you touch the throttle, making the truck feel quick and agile around town and on the highway.”
It should be noted that it’s not clear if Motor Trend or Car and Driver’s trucks were 4x4s nor if they had tonneau covers on them. Autoblog hypermiled a rear-wheel drive Silverado RST with a tonneau cover in a similar fashion to Car and Driver and saw a fuel economy average of 40.6 MPG as well. Chevy engineers have allegedly eked as much as 47 MPG out of the truck in testing, too.
Reviewers had some trouble seeing the benefit of the 3.0-liter Duramax engine over the V8s, however. The 5.3-liter and 6.2-liter V8 versions of the truck can tow more (the Duramax truck is rated 9,700 lbs max) and it may take a while to offset the price premium of the engine with fuel savings if you do not live in an area where diesel is inexpensive. That said, the Duramax-equipped truck will be very efficient whilst towing, so it may be worth it for those who find themselves towing long distances often.
