Powertrain
The DTS is equipped with the technologically advanced Northstar 4.6L V-8 engine and mated to the Hydra-Matic 4T80-E four-speed automatic transmission - a proven combination that assures powerful, sophisticated performance.
The Northstar 4.6L V-8 engine is available in two configurations: the 291-horsepower L37 and the 275-horsepower LD8 (horsepower and torque figures are preliminary, pending certification*). The L37 version is a responsive, higher revving powerplant with more peak horsepower. The LD8 puts more emphasis on quick launch and part-throttle response with greater peak torque.
