According to Fuelly, the best 320d is 41mpg but the majority is 34. The gas models are high 30's and the majority is 41.

The best 123d is 43 but the majority is in the 30's. The gas models are hi 30's:

So for all that C02 and particulates from diesel, a gas hybrid with an even smaller gas engine in those cars would deliver the same performance with less fuel and emissions. And, anything that's done to make the car lighter or have less drag helps the hybrid. No matter the car, a hybrid version of it will deliver flat out more mileage/less emissions with the same performance.

My statements about diesel were based on the US infrastructure.
