In the world of strict emission norms like the modern day, naturally aspirated engines are 'endangered species'. A very fine looking car to come with a naturally aspirated engine in the modern world is the Ferrari F12. Rumours have saying it could swap a few cylinders for turbochargers.
But according to sources, the next generation Ferrari F12 could retain its naturally aspirated V12 engine. To meet emission norms, the car would be smaller and lighter, but with more horsepower. Speculations indicate that the next generation Ferrari F12 could produce around 20bhp more than what the F12TDF currently makes (769bhp).
The Ferrari F12TDF is powered by the same 6.3-litre V12 engine that does its duty on the standard F12, but is lighter by 110kg. The engine produces 769bhp and 705Nm of peak torque, mated to a 7-speed dual clutch gearbox. The F12TDF has a top speed of 340km/h and can accelerate from 0 - 100km/h in 2.9 seconds.
Now, coming back to the next generation F12, the car will receive an advanced active aero to keep the car on the ground and pointing the right way around corners. Four-wheel steering could also be featured as standard. The next gen car is expected to have a top speed around 350km/h plus.
There are also rumors that Ferrari could introduce a hybrid powertrain for the next generation F12, but thanks to sources, that has been ruled out now. Ferrari has not revealed the exact time frame as to when the car will be launched, but it can be expected around 2019.
