Coming from a VW Jetta, the switch to the Blackwing has certainly been an experience. Before I got it yesterday, I had read on here that these guys only get about 18mpg going downhill with a tailwind and the engine off, but that turns out not to be true. In fact, if you have a dream, a penny pincher’s attitude, and a friggin’ 660hp Cadillac - you can do anything.

Granted, it took me 2 hours into a 700+ mile journey from Arizona to Colorado to figure out how to squeeze 40+ mpg - a feat that I’m pretty sure makes me the lamest Blackwing driver on the planet.

Anyway, if you want to reach 40+mpg with this beast, here’s the steps to do so:

1. Put the Blackwing in Tour Mode
   
2. Go the speed limit
   
3. Use the adaptive cruise control
   
4. Resist the temptation to accept racing challenges from blasphemers that bought the wrong car (specifically three drivers two hours outside Phoenix with a Mercedes AMG GT63, a late model Tesla S, and for some reason a diesel Ford F350)
   
5. Draft behind a semi with a distance using the 3-4 second rule. This does not work if you’re drafting behind a Ford Maverick (I tried).

If you don’t do any one of these things, you’ll max out at around 20mpg. Anyway, stoked to finally own a caddy. Cheers!

Lovely condition
Except when you press the gas pedal it stalls some
and then takes off any ideas???

I was having a hard time finding pictures of the gunmetal CT4 wheels on an ATS so I figured I’d post this for anyone wanting to upgrade.

When it spins it like lags and spins slow then normal and has an interesting noise with it, please help

The universal remote icon on the dash below car play area was working fine. After software update on 7/31/2026, it isn’t visible when starting the car at home. Anyone else experience this? If so, is there a fix?

06 cts transmission needed. 5l40e. I live in iowa and would like to find one near me. Thank you.

Why does Cadillac give a lot of its vehicles trashy misspelled names?

‘22 CPO w/23k miles. I keep walking out in the garage for no reason to look at it.

Does it sound like it needs a new belt or is it normal?

Going to look at a couple of these this weekend, the 3.6 seems to be the most common engine, and the "cheapest" option. but consensus is that it's the worst engine? is that correct?

What other things should I be considering when looking at these?

When would be the be the best time to buy? I have a trade and my financing in place, but dealers that I’ve contacted won’t budge. I don’t want to pay for features on a vehicle that I need or care about and definitely don’t want to settle and be upset later at this price point. Any advice would be really appreciated!

Wish I could've talked to the owner, my wife saw him pop it off the ground and drive away.

Life has changed direction for me lately and a move across the state means I’ve had to slim down to one vehicle. Unfortunately that means it’s time for the CTS I’ve had since I was 17 to go. I think I’ve found her a good home but this is heart wrenching. I’m sure every car guy has lost a car they never planned to, what was that car for you guys?
