With the base 2.7 L engine churning out 310 horsepower and the V8 hitting 355, the V8 seems to have the initial advantage. Drivers will however find this edge isn’t overly significant as the V8 pulls at 383 lb-ft of torque at 4100 RPM while the I4 achieves 430 lb-ft of torque at 4100 RPM, feeling more reminiscent of the low-end pull characteristic of a diesel engine.
