Infiniti has shrugged aside concerns over next year’s reduction in the CO2 threshold related to capital allowance and lease rental restrictions.

The changes, announced by the Chancellor in his March budget, see the level at which the 15% lease rental restriction and 18% capital allowance disadvantage comes into play reduced from 160g/km to 130g/km.

Infiniti tweaked its M35 Hybrid model to bring emissions down from 161g/km to 159g/km this year as it looked to dip under the original threshold; the new level which is introduced next April, make those changes redundant.

“We are all about performance motoring but it has to be sustainable,” said Tony Lewis, Infiniti director for Northern Europe.

He points to developments in electric, hybrid and range extenders but believes the M35 Hybrid buyer is less sensitive to the lease rental restrictions.

However, that’s not the case for the forthcoming G car. Consequently, Infiniti is working with Mercedes-Benz to use its more efficient engines in certain models.
