General Motors will introduce a new dual overhead cam (DOHC) 6.2L V8 in its next-generation C3XX pickup trucks, a new report finds. GM currently uses an overhead valve (OHV) pushrod version of the 6.2L V8 in its pickup trucks. The new engine is said to debut in 2012.
According to an internal UAW document made public by PickupTruck.com, the new engine will use variable valve timing and could use a four valve per cylinder setup. In addition, the engine will also use GM’s active fuel management — a technology that shuts down four cylinders at cruising speed.
But GM will not completely abandon pushrod engines. The document also outlined a new engine to replace the current 5.3L V8 engine but will retain its OHV design. The document failed to reveal the displacement of the new engine.
GM currently only produces one DOHC V8 — the 4.6L Northstar engine found in Cadillac and Buick models.
