Cadillac Escalade ESV
The Escalade moved to the new GMT900 platform for the 2007 model year. The regular Escalade was again joined by a stretched ESV version as well as a new EXT sport utility truck.
The Escalade uses an all-aluminum 6.2 L Vortec V8. This pushrod engine includes variable valve timing, a first in a mass-produced non-overhead cam engine. The system adjusts both intake and exhaust timing between two settings. The engine produces 403 hp and 417 ft·lbf (565 N·m) of torque. A new six-speed 6L80 automatic transmission is used. The new body completes a 0.363 drag coefficient.
