Sorry, I missed another add in cost.
$95 per g of carbon over 95g per km, an EU rule, so for the petrol Pug 2008 at 109g/km, that would be 14 x $95 = $1330, which is around £1030 extra cost for producing the petrol engined version.
It’s not going to be that many years before the EV versions will be more economic for the manufacturers to produce.
