All 2021 model year Cadillac models, from the CT4 and CT5 sedans, XT4, XT5 and XT6 crossovers as well as the full-size Escalade SUV, feature automatic stop-start technology designed to improve fuel economy and reduce exhaust emissions.
The same thing could very nearly also have been said of Cadillacs of the previous model year, but for one thing: the 2020 Escalade, the last model year of its generation, did not have automatic stop-start available even as an option. On all-new 2021 Escalade, engine automatic stop-start is standard when fitted with either the naturally-aspirated 6.2L V8 L87 gasoline EcoTec3 engine, which produces 420 horsepower and 460 pound-feet of torque, or the 3.0L I6 LM2 turbodiesel Duramax, rated at 277 horsepower and 460 pound-feet of torque.
Luckily, on all 2021 Cadillac models, auto engine stop-start can be disabled via a button within the vehicle. However, the feature is automatically enabled at every ignition cycle, meaning that those who desire to drive with auto stop-start disabled will have to press the disable button every time they turn on the car. The disable button comes in the form of an “A” with a circle around it.
Auto engine stop-start will begin to be eliminated once the Cadillac begins its EV onslaught, which will start with the Cadillac Lyriq crossover. The Lyriq is set to launch in the first quarter of 2022, nine months ahead of schedule. Automatic stop-start is a technology for internal combustion engines, and the Lyriq – naturally – won’t have one of those.
The Lyriq is the first of six Cadillac electric vehicles expected to go on sale between now and the end of 2025. The others are two more crossovers called Optiq and Symboliq, an EV version of the Escalade, the Celestiq flagship sedan which will start at $200,000 or more, plus a mysterious model so far referred to only as the “low roof” EV that’s expected to be a cross between a sedan and a coupe.
Cadillac will lead the charge for electric vehicles at General Motors, and the move will raise the proportion of EVs in Cadillac’s line-up from the current 0 percent to 50 percent. It would be equally true to say that the proportion of models with automatic stop-start will drop from 100 percent today to 50 percent.
