If engineering is referred to fuel economy, emission, power, etc., then look at the below figures (from TopGear magazine).
BMW 320d: 58.9mpg, 125g/km, 175bhp, 258lb/ft, 7.9sec.
Honda Accord 2.2i-DTEC: 50.4mpg, 148g/km, 148bhp, 258lb/ft, 9.6sec.
Mitsubishi Lancer 2.0 DI: 44.8mpg, 165g/km, 138bhp, 229lb/ft, 9.6sec.
Toyota Avensis 2.0 D4: 47.9mpg, 157g/km, 175bhp, 295lb/ft, 8.5sec.
No doubt Toyota is the best Japanese car maufacturer, but the figures show Avensis is not the best here. BMW is now probably the best diesel car manufacturer in the world.
