Piston Slap: Spare Me Your AWD Drama

Greetings, Sajeev — longtime reader, first time writer, and I enjoy the content your column adds to TTAC! (Woot! — SM)

I recently acquired an all-wheel drive 2014 Cadillac CTS with about 15,000 miles on its factory 255/35 R19 Pirelli P7 run-flat tires. Looking ahead to an upcoming 3,500 mile driving trip, I have concern for the durability/drivability of the run-flats. The CTS is not equipped with any wheel-changing tools (jack, wrench, spare tire/wheel). A spare tire assembly (for the CT6) is available online, but I believe the standard compact spare is too small in diameter to be compatible with the 19-inch wheels on the AWD drivetrain.

  • Hi There I dig the boxy retro looks, I don't care if it looks like a Rivian which looks like an old Scout. I'm skeptical about the price, as others have mentioned, my guess is when this ships, in 2027, it'll be $90k. I do like the range extender generator on board. Until we get better battery technology, it's either that or a plug-in hybrid for me. Full EV is fine in an urban environment with access to lots of chargers. Though, the irony there is, once everyone has an EV, finding an open charger will be impossible. So many negatives in the EV future.

So their marketing department wasn't ready for this launch at all. I seriously doubt this will launch in 2027, or that any of their products will be less than $90K, or that any of them will be available with some sort of combustion engine of any kind.
