Top 5 economical executives

  • Five lowest emission executive models
  • Only one falls into lowest BIK banding for diesels
  • One hybrid included, remainder diesels

Volvo's new sub-120g/km of CO2 S80 DRIVe saloon is the lowest emission executive car on sale in the UK.

The recent revisions to the model have brought emissions down from 129g/km to 119g/km, qualifying it for the lowest 13% diesel benefit-in-kind tax banding.

The S80 uses a 1.6-litre turbodiesel with 109bhp which returns fuel economy of 62.8mpg.

Its closest contender is the new BMW 520d, which goes on sale next month. This uses the firm's EfficienctDynamics fuel saving devices, employing stop-start engine technology for the first time on the 5 Series. As a result it falls into the 18% BIK band (based on the 2010/11 tax year which begins this April).

Diesel-engined versions of the Mercedes-Benz E-Class and Audi A6 take third and fourth spot, both in the 19% BIK band, while the Jaguar XF 3.0D is tied for fifth spot with the petrol/electric Lexus GS450h hybrid.

However, the Lexus enjoys a significant BIK band saving as it currently enjoys a 2% BIK band discount thanks to being a hybrid. However, this dispensation is due to end at the start of the 2011/12 tax year. Click here to read our special report into changes to the way hybrids are taxed.
