Infiniti may not have managed to make the biggest mark on the car landscape in the UK, but the news of a new G-Series is interesting because it seems likely it will offer a more interesting design and more Europe-focused powertrains. The current Infini G37 comes as a 3.7 litre V6 and nothing else, which doesn’t exactly help sales in Europe where economy and CO2 levels are a bigger driver of sales than they are in Infiniti’s main market, the USA.
