The Cadillac Escalade is all-new for the 2021 model year, introducing a fresh fifth generation for the iconic SUV nameplate. Although the Escalade might not be the first choice for new-car buyers when it comes to fuel economy, Escalade customers will no doubt still like to know what to expect with regard to fuel returns. As such, GM Authority is taking a closer look at fuel economy figures for the 2021 Cadillac Escalade without automatic stop-start.
For those readers who may be unaware, the ongoing global microchip shortage has resulted in General Motors removing automatic engine stop-start from certain models in its full-size SUV lineup, including the 2021 Cadillac Escalade.
The feature is designed to reduce fuel consumption and emissions by automatically cutting the engine when the vehicle comes to a stop, such as at a stoplight or in heavy traffic. Once the driver removes their foot from the brake pedal, the system restarts the engine, allowing the vehicle to once again move forward.
However, as of June 7th, certain 2021 Cadillac Escalade models that would normally come equipped with automatic engine stop-start are no longer produced with the feature, specifically Escalade models equipped with the naturally aspirated 6.2L V8 L87 gasoline engine. The 6.2L V8 L87 is rated at 420 horsepower and 460 pound-feet of torque, and connects to a 10-speed automatic transmission.
The 2021 Cadillac Escalade is also offered with the 3.0L I6 LM2 turbodiesel Duramax, rated at 277 horsepower and 460 pound-feet of torque. Escalade models with the diesel engine continue to come equipped with automatic engine stop-start.
Check out the table below for an exact breakdown of the mpg differences between 2021 Cadillac Escalade models with automatic engine stop-start, and 2021 Escalade models without the feature. To note, the EPA rates both the standard-length Escalade and the extended-length Escalade ESV with identical mpg figures.
