John and Helen Taylor traveled 14,580 km in Australia (9,100 miles) using a Peugeot 308 with a standard 1.6 HDI 110 HP diesel engine. The Taylor's 308 was a standard model, just like the ones you can buy it from the showroom (at least in Europe and Australia), including Michelin Energy XM1+ tires. They used 453.94 liters of Shell diesel for the trip, which broke a previous record (with a 307) of 3.49 l/100 km (67 mpg U.S.). The CO2 figures (which Peugeot states include the supply chain) were a mere 90.3 g/km.
This makes it almost unnecessary to wait for the hybrid! But, please, Peugeot mate this powertrain to a hybrid system and treat the exhaust gases.
