Cadillac CT6 and My Favorite Murder

One of my Wife’s birthday presents in August was a trip to see Karen Kilgariff and Georgia Hardstack from the  My Favorite Murder podcast live when they were to be in Dallas.   The PodCast live performance was this November weekend, and what better weekend for us to have a 2018 Cadillac CT6 in the driveway for the ride downtown?

The CT6 is the largest Cadillac sedan, with a huge 122.4″ wheelbase — the space between the front and rear axles.  That’s almost a foot longer than the other large Cadillac sedan, the XTS.

I had driven a CT6 Platinum with the 3L TT but had not tried the ‘standard’ CT6 with 2L Turbo or 3.6L V6.   In a way this weekend’s test drive was a delight to find just how much Cadillac one can get for a least expensive CT6, around ~$50K.

The test CT6 had the LGX 3.6L autostop, variable displacement V6 engine for 345 hp.  The all wheel drive (AWD) system requires no attention, but gives you the benefit of four wheel propulsion if the weather or conditions demand.  A lot of our CaddyInfo fans have expressed concerns about start/stop, but I am getting quite used to it.  Start/stop technology is when the car automatically turns the engine off when stopped, then turns it back on when or before you need to proceed.  There is a button on the dash to turn this feature off, but I think the more time we spend with it the more we will trust the Cadillac will handle it and let it do so.

The real treasure of the CT6 design is it is a full size car with the svelte shape of a midsize

For our drive down to the historic Majestic Theater in downtown Dallas, I hooked up a USB cable and my iPhone so we could use the huge 10″ center infotainment display for navigation.  The route was pretty easy, except we knew one of the bridges on the way was under construction and impassable.   Also, once I get downtown in Dallas I find careful planning and route management are the order of the day.

Parking in a local public parking garage was uneventful — we bypassed the ‘compact car’ sections for an open area higher up where the CT6 could have some room.

We arrived early for the Podcast show, and walked over to Dallas Chop House for coffee and dessert in the lounge area.    That worked out very well for enjoying our wait, but we footnoted it for a return trip for a full steak dinner another trip.

The My Favorite Murder Live! 10:30 pm show started late, but was engaging and funny.  Our seats in the theater were front-row after the orchestra pit, and we laughed throughout the two woman show about every but murders, and murders.  My Wife is a big fan of the podcast.  We had VIP tickets and we stayed after the show for my Wife to meet and have a picture taken with the Stars.

The drive home went very well, with the CT6 happy cruising at the speedlimit and limited traffic due to the very late hour.  Overall I enjoyed the weekend test drive.

My favorite features of the CT6:

  • Wonderful seating and view out the front, huge leg room and space in the rear seats
  • Variable displacement V4/V6 feature — I like the power of the LGX V6 but I would like to explore the ability to go into V4 mode and get much better fuel economy more.
  • Selectable Dash display — although limited to 2 selections in this model.

My nits about the CT6:

  • Cadillac should have gone even more dramatic with the styling
  • I would make a Heads Up Display a standard feature; this model did not have it
  • The 3.6L V6 and 3L TT V6 are only available in AWD, not RWD.

Crest Cadillac in Frisco, Facebook, provided  the car for this test drive.   I am also a Crest Cadillac customer — I bought my ATS-V there, and recommend them to others.

Video shot back into the XLR.

Turning the air vents appeared to improve the audio.

Unedited to show iphone on mount to youtube to you.  iPhone runs out of storage and shuts video down abruptly at the end due to too many photos and videos lol

Cadillac XLR LH2 V8 Tuning – Tune 10B MBT

Tune 10B uses MBT values, adjusted for static retard and VVT adders, as the main spark table.  MBT, or minimal timing for best torque, is a table that shows Cadillac’s calculated ideal timing.  Often it cannot be reached without knock.

XLR Tune 10B Comparisons

The results look very good — 327/313 for one run, 323/309 corrected 2nd gear HP/Torque for the other.

XLR Tune 10B VirtualDyno Comparison

The virtual dyno results for the same two runs were similar — 269/256 and 263/252 which divided by 0.8 for automatic losses would be 336/315 and 329/315 Hp/Torque.

XLR Tune 10B-0457

There was some slight KR in one run, although it did not repeat in the other run.

XLR Tune 10B-0747

All in all I am happy with 10B and will keep gathering more data on this tune to see where to go from here.
