Mahindra allegedly tried to break their agreement with Global Vehicles, possibly when GV had orders for about 50,000 trucks. They did this by delaying emissions certification from the Punishment Agency. The whole deal is tied up in court. I wouldn't hold my breath on the Mahindra.

I haven't heard anything about a diesel Tacoma, no mention of it on the Diesel Technology Forum, and they're on top of what's happening in the industry. Cummins is experimenting with a new engine in the Nissan Titan, but I don't see the point of that, as the Titan is mediocre at best, and the market is in a smaller, economical truck IMO as opposed to a full sized half-ton.
