Cadillac today confirmed that it's bringing back the three-row mid-size XT6 SUV, which will once again feature a gas-powered engine. Cadillac didn't say exactly when the new XT6 will arrive, but it confirmed that it won't debut until after the redesigned XT5 launches in 2027. The news is another step backward from Cadillac's one-time commitment to selling exclusively electric vehicles by the end of the decade.
