The L8T is meant for grunt work, thanks to an impressive 464 lb-ft. of peak torque that arrives 200 rpm sooner (and is 22 percent more) than GM’s previous 6.0L V-8 HD gasoline engines. Direct injection technology provides precise fuel control and enables a higher compression ratio that broadens the torque curve and contributes to a power output of 401 hp. This broad torque band provides a stronger feeling of on-demand power at all speeds.
