At the introduction of the Nissan Forum concept, VP of Product Planning Larry Dominique talked about diesels beyond the 3.0L V-6 being developed for the Maxima. If the slow-selling Titan pickup truck survives into the next decade, Nissan wants a diesel engine to put in it. By that time, all of the domestic truck makers will have new clean diesel engines in their light-duty pickup trucks. Even Toyota has a new 4.5L diesel V-8 in foreign market versions of their new Land Cruiser that could be adapted to the Tundra. That leaves Nissan looking for a partner. They had been negotiating with International Truck, who currently supply diesels to Ford for their Super Duty pickups. However, those talks have apparently not panned out. According to Dominique, Nissan is still trying to find the right partner.
