Still not the big diesel I'd hoped they'd come out with, but it's a start,

Class Turbo diesel V6
The V9X is a common rail V6 turbodiesel developed by the Nissan-Renault alliance, and first installed in the Renault Laguna in 2009. It was subsequently made available for all longitudinal engined including Infiniti, along with Nissan Pathfinder, Nissan Navara, Infiniti FX, Infiniti EX, Infiniti M an Renault Laguna.
Engine Power and CombustionThe V9X V6 diesel engine develops 240 hp (179 kW) and 550 N·m (410 lb·ft) of torque.
The combustion chamber design was optimized to improve the balance between emission levels and fuel efficiency; the compression ratio was lowered to 16:1 to benefit not just economy and emissions but also noise, vibration and harshness (NVH).
Class-leading levels of torque and highly competitive specific power outputs are delivered thanks to the adoption of a comparatively large single turbocharger, which is mounted within the vee of the engine, an intercooler and the use of the latest generation of Bosch Common rail fuel injection. This system incorporates piezo injectors and operates at 1,800 bar.
Power output is on target at 240 hp (179 kW) while the class-leading torque output of 550 N·m (410 lb·ft)(for rear and four-wheel drive applications) is better than the target. Peak torque is achieved from as low as 1,750 rpm and is available all the way to 2,500 rpm, while as much as 500 N·m is available from 1,500 rpm. Idle speed is an exceptionally low 650 rpm with none of the NVH usually associated with a diesel.The result is strong low-end performance with comfortably refined delivery. Special tuning of the exhaust note provides a pleasantly sporting note at about 2,500 rpm under hard acceleration.
