Elaborating on the point about AWD weight, Alfa Romeo boast their AWD system adds less than 110lbs to drivetrain weight, but it can only handle 60% of the engine torque in the i4 cars, and only 50% of the 600Nm max torque in the Stelvio Quadrifoglio. Jaguar claims to be able to send 100% of engine torque to the front wheels, which is 680Nm in R models.

That's a substantially more robust drivetrain in the F Type, and it almost certainly must come with extra weight to achieve that. Alfa uses aluminum for the prop shaft to the front diff on the i4, and steel on the V6 (the shaft to the rear on both is carbon fiber), whereas Jaguar use steel for the front prop shaft (which handles more than 2x the torque of the V6 Alfa).
