Volkswagen's new 4.2-litre TDI V8 engine produces 340 PS and 590 lbs ft of torque. It's called a V8 because its 8 cylinders are arranged in 2 banks of 4, forming a V shape. Despite its substantial power and torque outputs the new engine is still capable of achieving 31 mpg on the combined cycle while emitting 239 g/km of CO2.
