2. Porsche Panamera D

Another of Porsche’s more frugal offerings is the Panamera D.

It uses the same 3.0-litre V6 engine as the Macan S Diesel and produces slightly more power at 296bhp, but as a result it is fractionally less efficient with CO2 emissions of 169g/km.

The BIK company car rating is a little higher standing at 29 per cent.

However, Porsche has also started to introduce Plug-in Hybrid technology to its models and the Panamera is one of those to benefit from electrification.

The Panamera E Hybrid emits only 71g/km, resulting in a BIK company car rating of only 5 per cent
