Nissan's domestic twin turbo diesel engine (YS23DDTT 2.3 dci) unavailable on newest Caravan? This engine same as inside navara NP300 & X-Terra. Two-stage turbocharging makes this engine smaller size but huge torque at lower RPM. Also equipped with DPR & SCR for Euro-6d emission standard. Why Caravan not use smaller diesel engine under 2000cc for reducing gross weight? Also twin turbo can make small engine has same or higher power as big engines. Nissan Caravan must downsize diesel engines for optimized vehicle weight distribution
