Soon enough, General Motors will pull the wraps off of Cadillac’s new XTS flagship sedan, marking the official demise of both the aging DTS and STS sedans. Until then, however, the two top-end Caddies live on, albeit with fewer options than before.
According to USA Today, the STS sedan will no longer be available with GM’s 4.6-liter Northstar V8 for the 2011 model year. The only mill on hand is The General’s direct-injected 3.6-liter V6, cranking out 302 horsepower and 272 pound-feet of torque. Power still gets to the ground via rear- or all-wheel drive. V8 power is nice, but since the Northstar only churned out 18 more horses and 43 more pound-feet than the V6, it won’t be too tearful of a goodbye, especially when you consider the six’s better fuel economy. The supercharged, 469-hp STS-V was put out to pasture last year.
