Admittedly it's difficult when comparing against the slightly bigger diesel engine, but the performance of the petrol version was extremely disappointing. The P11D value of the 1.6 GDi is £17,110 compared to £20,425 for the 1.7 CRDi, while CO2 emissions for the petrol version are 149g/km as opposed to 135g/km for the diesel.Given the 3% diesel BIK surcharge, an employee driving the diesel variant would fall into a 20% BIK tax band, compared to 19% for the petrol car. That would mean a 20% taxpayer driving the 1.6 GDi paying £650 per year compared to £817 for an employee driving the 1.7 CRDi.But how do the employer's costs compare? First year VED rate for the 1.6 GDi is £130 compared to £115 for the 1.7 CRDi, while Class 1A NIC costs are £449 and £564 respectively.Meanwhile, the all-important running costs on a three-year/60,000-mile cycle favour the petrol variant on paper. Its 37.07p per mile rate includes fuel at 13.72p per mile, compared to 38.18p per mile with fuel at 11.64p per mile for the diesel. However, if you travel 100 miles in the 1.7 CRDi at 44.4mpg you will pay around 14.38p per mile for the diesel, compared to 18.75p per mile at 33.1mpg for the petrol.

If you achieved 55mpg over the life of the car instead of 45mpg, you would save 243 gallons of fuel. Diesel now costs £6.29 a gallon on average according to the very useful fuel price checker on the Fleet News website, so the potential saving is £1,528.Some fleet managers are being besieged by drivers complaining that their fuel reimbursement rates don't reflect the actual cost of fuel, but what they really mean is the rates don't reflect the cost of their driving style.Achieving 55mpg is equivalent to a fuel cost of 11.4 pence per mile, but achieving just 45mpg is equiv-alent to a fuel cost of 14ppm.With fuel prices continuing to rise, that's a lesson that drivers including myself will have to learn on their increasingly slow journeys - full throttle; empty wallet.
