Just guessing... It would come down to 1. volumetric efficiency (intake swirl, compression ratio, chamber shape etc..) 2. Bore (the larger the piston area - the larger the force on the conrod to the crank) 3. Stroke ( the longer the stroke the larger the torque <turning force> at the crank) 4. Firing order/sequence
The 2 Litre 4cyl would probably have bigger piston diameter AND longer stroke than 2 Litre V-6 . Only one cylinder can fire at a time so it looks like the 4cyl is the grunty one BUT The 6cyl has more OVERLAP so after one cylinder fires the next one in sequence fires sooner than in a four cylinder. If the volumetric efficiency of both engines is the same then I would expect the 4cyl to have the higher torque output per cycle and <just guessing> max. torque measured on dyno. When averaged out though (by the flywheel) the 6cyl has the smoother torque curve and could be the winner.
