Toyota is quick to implement its new ultra-efficient small-capacity engines after announcing the high-compression series earlier this month. The Passo and Yaris/Vitz lineups have both been updated to include the new motors, and next on the list is the second-generation Toyota Aygo.

In the new Euro-market compact citycar, the newly-developed 1.0 litre engine will average around 24 km per litre, with CO2 emissions of 95 grammes per kilometre. No output figures have been released, but the same engine makes 69 PS at 6,000 rpm and 92 Nm of torque at 4,400 rpm in the JDM Passo.

The three-pot is lighter than before, runs a higher 11.5:1 compression ratio, and features a cooled exhaust gas recirculation system (EGR) to achieve an unprecedented maximum thermal efficiency of 37%. Toyota claims a near 30% improvement in fuel economy over current models.

So that’s Japan and Europe covered. Care to guess when we’ll be getting the new engines?
