One popular choice was the 2.0L Turbocharged Inline-4 engine, producing around 200 horsepower and 207 lb-ft of torque. Other engine options included the 3.2L VR6 engine, which produced around 250 horsepower and 236 lb-ft of torque, and the 2.0L TDI diesel engine, which produced around 140 horsepower and 236 lb-ft of torque.
