Three-cylinder turbo or four-cylinder naturally aspirated engine?

Hi.

As a long-term keeper would you recommend a turbocharged three-cylinder petrol engine or would a four-cylinder non-turbo be a safer bet?

We'll be buying a new car next year. There are so many variants out there it's doing my head in.

We're not quite ready for all electric yet.

Hi Teresa,

I'm afraid there's no definitive answer to that as every engine is so different. There's generally less to go wrong on a non-turbocharged engine, but they're usually less efficient and less powerful as well.
