Best used cars with naturally aspirated engines

Downsizing has signalled the end of the non-turbo, naturally aspirated engine – so grab one while you can.

One of the most documented aspects of the car industry in recent years has been the trend for downsizing: making engines smaller to meet ever more stringent emissions regulations and the desire for improved fuel economy. In the face of this, the responsibility for clawing back power – to satisfy the thirst for performance from both marketing types and customers – has fallen to the turbocharger, and the naturally aspirated engine is rapidly becoming a thing of the past, like carburettors and those anti-static strips that used to hang o the back of Ford Cortinas. 

Of course, there's a lot more to the engineering than simply 'putting the power back’: a turbocharged engine produces power, and even more importantly torque, without lots of indulgent, fuel-slurping revs. sadly, it’s those same revs and uncorrupted exhaust gas ows that give naturally aspirated engines their core appeal – their voice and their response.
