2011 Cadillac SRX
So a turbo V-6 Cadillac sounds like a great idea, right? How about if we stick a fairly tall, soft suspension under it, give it a crossover body and pair it with an automatic only? Not so much, eh? That's apparently what buyers of the Cadillac SRX felt, as well, as the 2.8-liter turbo model saw a less than 10 percent take rate and is now being axed.
The punch SRX Turbo was potent, wrangling 300 horsepower and 295 pound-feet of torque from the diminutive (by modern standards) V-6 engine and turbo. Fuel economy was fairly dismal, however, at just 15/22 mpg city/highway.
That may have had some impact on the decision matrix, but issues relating to rare but highly publicized engine failures in the Turbo due to owner-induced engine failure (pre-ignition due to misfueling) may have contributed to the Turbo's demise as well.
GM hasn't announced any plans to replace the 2.8 turbo, instead leaving the popular 3.0-liter V-6 to soldier on alone.
