The V12 is supposed to be the top engine in the lineup, so why does it make nearly 100 fewer horsepower than the most powerful V8 available, despite producing almost 150 lb-ft more torque? Is it for economy reasons? I reckon the V12 can be easily tuned up to deliver well over 700 horsepower, thereby lifting it well above the V8, and there might just be space in the range for such an extreme variant. Also, I have spotted a typo in your spec sheet:
It should read: 48-valve Direct-Injected Twin-Turbocharged V12 - an eight-cylinder engine with 48 valves would need six-valve heads, something which is impossible to make in Automation.
