The arrival of the 2021 Cadillac Escalade heralds a brand-new generation for the premium full-size SUV, with the fresh utility sporting a long list of changes and updates. One of the biggest highlights is the addition of a new diesel engine option, which is a first for the Escalade nameplate. Now, we’re taking a closer look at these two engines in the following comparison.
Let’s start with the new gasoline-powered 6.2L V8 (production code L87). Arriving as a next-gen followup to the Escalade’s previous gasoline-powered 6.2L V8 (production code L86), the new ‘eight can also be found in a variety of trucks and SUVs under Cadillac’s parent company, General Motors, including the Chevrolet Silverado 1500 and GMC Sierra 1500.
Equipped as standard across the 2021 Cadillac Escalade lineup, the new V8 is naturally aspirated and features an overhead valve (OHV) configuration, otherwise known as a “push-rod” design. Fuel economy is bolstered by an automatic engine start/stop system and variable valve timing. Output is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, while a 10-speed automatic transmission handles the cog swaps.
Up next we have the new 3.0L inline six-cylinder turbodiesel (production code LM2). Like the standard gas-powered V8, the 2021 Cadillac Escalade’s new diesel powerplant can also be found in a number of GM full-size half-ton pickups, including the Silverado and Sierra, with roots in GM’s Duramax engine line. The 2021 Escalade’s new diesel engine is available in the Luxury and Platinum Luxury trim levels, but is not offered in the Premium Luxury, Sport, or Platinum Sport trims.
Like the gas engine, the optional diesel powerplant features an automatic engine start/stop system. Output from the oil burner is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm, which makes it a solid choice for “confident performance and trailering capability,” as stated by the automaker.
Unfortunately, Cadillac has yet to release exact specs on the 2021 Cadillac Escalade’s trailering capabilities, although it should be mentioned that the new Escalade will offer an available Trailering Integration Package that adds up to nine camera views for easy hitching, as well as an integrated trailer brake controller, trailering app, tire pressure and temperature monitor, and Extended Side Blind Zone Alert.
Like the gas engine, the new Escalade’s optional diesel powerplant mates to a 10-speed automatic transmission.
