General Motors has dropped one available powertrain combination from the 2021 GMC Sierra 1500 SLE and Elevation trim levels.
For the time being, the automaker will no longer build the 2021 GMC Sierra 1500 with the 5.3L L84 V8 engine and GM ten-speed automatic transmission in either the SLE or the Elevation trim levels, although buyers will still be able to order the SLE and Elevation with the 5.3L L84 V8 engine and the older GM eight-speed automatic transmission. The 5.3L L84 V8 produces 355 horsepower and 384 pound-feet of torque in the 2021 GMC Sierra 1500.
As we pointed out in a previous article, the 2021 GMC Sierra 1500 with the 5.3L L84 V8 is available with either the GM eight-speed automatic or GM ten-speed automatic transmission. The ten-speed transmission carries a $200 premium over the eight-speed in trim levels where both are offered.
In addition to the 5.3L V8 engine, the 2021 GMC Sierra 1500 is also offered with the turbocharged 2.7L L3B four-cylinder engine and the Duramax 3.0L LM2 inline-six turbodiesel in the SLE and Elevation trim levels. The 2.7L L3B four-cylinder is the base engine in the SLE and Elevation trims and comes paired with the eight-speed automatic. The Duramax 3.0L inline-six turbodiesel engine is the priciest engine option in these two trim levels and is paired exclusively with the ten-speed automatic.
It’s wroth pointing out that there is still a way to get the 2021 GMC Sierra 1500 with the L84 V8 engine and ten-speed automatic transmission, as this powertrain combination is still available with the pricier SLT, AT4 and Denali trim levels.
The 2021 GMC Sierra also received a small price increase recently. Under the revised pricing structure, the base Sierra and SLT trim levels will be $400 more expensive than they were previously, while the Denali and AT4 trim levels will receive respective price increases of $500 and $600. The Elevation also gets a price increase of $900, while the SLE gets the biggest price increase of $1,000.
