6th place: Polestar 1 (54 g of CO2/km driven)
Here is an unusual and frankly exotic car. The Polestar 1 was developed mainly to impress, to announce the arrival of the new Polestar brand. But underneath this coupe based on the Volvo S90 sedan - at least in terms of its styling - is a high-performance plug-in hybrid that emits very few emissions into the atmosphere. The problem is that production is very limited and the price is in the - gulp - $200,000 range.
