Every vehicle in the 2021 Cadillac lineup, from the compact Cadillac CT4 sedan to the hulking 2021 Cadillac Escalade SUV, now comes standard with fuel-saving automatic stop-start technology.
The outgoing 2020 Cadillac Escalade was previously the only Cadillac vehicle that did not offer automatic stop-start. By comparison, the overhauled 2021 Cadillac Escalade has the feature, meaning that all Cadillac vehicles currently on sale have the technology. This is the case for every 2021 model year Cadillac vehicle in all available trim levels and with any powertrain configuration.
| Model | Auto Stop-Start |
|---|---|
| Cadillac CT4 | S |
| Cadillac CT5 | S |
| Cadillac Escalade | S |
| Cadillac XT4 | S |
| Cadillac XT5 | S |
| Cadillac XT6 | S |
Automatic stop-start, otherwise known known as engine auto stop-start, is a technology that enables the car to switch off its engine when it comes to a stop, such as at a stop light or stop sign, for example. The engine will then automatically turn back on when the driver begins to lift their foot off of the brake pedal. This technology provides an estimated fuel economy benefit of around three to five percent and can significantly decrease CO2 emissions for drivers who often find themselves idling at stoplights or in traffic.
Though automatic stop-start system is standard on all 2021 Cadillac models, it can be deactivated via a button on the center console. The auto stop-start system turns back on at each ignition cycle, meaning that those who prefer to drive with it off will need to hit the disable button every time they start up their Cadillac.
According to the U.S. Office of Energy Efficiency and Renewable Energy, less than one percent of all cars and light-duty trucks were equipped with automatic stop-start in 2012. Six years later in 2018, that number had risen to more than 37 percent. The technology is expected to become more commonplace as automakers look to meet increasingly more stringent fuel economy and tailpipe emissions goals set by federal governments the world over, so it’s highly unlikely that auto stop-start will be going anywhere on Cadillac products – save for the upcoming pure electric ones, of course.

Last week, I took delivery of my 2021 Cadillac XT5 Premium Lux/ Platinum and was very glad to see that I can disable the auto start stop. That feature co not be disabled on 2017 XT5.

The traffic in my small town is light so I do not have to idle for long periods at lights, etc . This feature is annoying if I forget to push the button to disable it . I am thankful it can be disabled .

If they ever make it so it cannot be disabled then there will no longer be a Caddy in my future. I am not sure if it will remember your last setting for it on or off, but from what I gather one has to disable it every time you start the car, and that is annoying.

If Auto Start Stop is a “feature” it is a very annoying one. You would have to be at long stop lights or traffic jams ( congested city driving ) for it to be of any benefit. The only justification for it would be some benefit on the EPA driving schedule that determines fuel economy ratings !

Glad there is a disable option on our new 2021 XT5. To this day, I still think the car “stalled out” every time it shuts down! Very disturbing! The idea is good, but the fuel/pollution savings are probably negligible in small town or country driving. No, I think GM has the right idea overall… just got to remember to push that “A” button each time! Keep up the improvements!

Needs to have the ability to turn off stop-start. And not every time !! Cuts down the AC in hot weather and is annoying. I won’t buy another Caddy if it comes without an ability to turn it off completely
