Believe its a twin-turbo 4-cyl if I remember correctly and turbo normalizing negates altitude considerations; hence why it has a turbo.
@soflorovers Agreed; seeing the torque curve will answer the remainder of the questions!
@mpinco that part about "it's still a 2 liter" is not valid if the map/curve is right for the vehicle and configuration in placed in.
LR Spec 2.0 Liter 4cyl: 296hp @295lb/ft
Cummins R2.8 (arguably the best crate motor anyone can buy): 161hp @ 310lb/ft
Look like pretty good numbers to me! But ask me about turbos and high altitude performance and normalizing in aviation cuz I'm not an LR engineer so they probably did better math on their vehicle than I did; one can only assume! Is density altitude on the ground at 9600ft the same as density altitude for the aircraft flying by at the same altitude; guess that depends on if we are turbo-charging or turbo-normalizing; modern ECU's can use variable turbos and manifold pressure to do both on the desires of demand.
In simple terms; turbo-charging alone is for on demand power required and turbo-normalizing maintains manifold pressure very similar to supercharging (I said similar in concept) in all environments so the vehicle does not perform any different through its entire operational range due to demand needs, altitude, etc. Means your power/torque curve does not change regardless of the environment under computer control. Generally, turbo-normalizing is not as ideal on engine life as compression/manifold pressure is always high where as turbo-charging is on demand only.
Disclaimer: these are simple terms in simple explanation.
