Thinking of changing to a 2020 model 318d or a 320d Sport. Cars look great but wondering if the 318d is a bit rough? Is it a different engine or just a de-tuned 320d engine?

Just concerned as I has a 2011 318d before and it was really sluggishly. But wondering if things have really moved on since then….

(Had a 520d and 530e in between)
