Kia Picanto ISG
Price: $18,590 CO2: 100g/km
Be it ever so humble, the Kia Picanto ISG is New Zealand’s most economical petrol-powered new car. That honour belongs to just one model, however: the entry-level Picanto ISG (for Idle Stop Go), which has the same 1250 powerplant as the rest of the range but drives through a conventional five-speed manual gearbox and features a stop/start system. It makes a big difference: the ISG model returns an official figure of 4.3 litres, while the four-speed automatic (sans ISG) sucks up a whole extra litre per 100km.
