    Hilux eh? Perhaps we'll see a Tacoma Diesel (highly unlikely :rolleyes:). But if Toyota wants to compete with the big 3, it'll need a better engine option for the Tundra. The i-Force V8 is getting long in the tooth and noncompetitive in mpg.

    The article says that fuel economy is improved 15% over the current engine.

    A hybrid tends to stay pretty close to maximum SFC while a diesel does not, so maximum SFC in a diesel is difficult to interpret.

    Don't know about gas engines, but the new 2016 Tundra will have a 5L Cummins V8 option. I think the same engine will also be in the Nissan Titan.

    Many don't hold out hope of this engine coming here, but the Colorado, and whatever the GMC is called, is getting a 2.8L diesel option and 8 speed transmission. Plus, Ram and Jeep have 3L V6 diesel option.

    To date, no hybrid truck has been competitive to the ICE in regards of towing. You even have to upgrade to AWD just to be able to do it in Toyota, and past Ford, hybrids. I know people do tow with the Prius, but Toyota says no to it. Which means if something goes wrong while doing it, you are SOL in regards to warranty, and possibly insurance. So a small diesel may be the only option for those that want a truck for actual work.

    Toyota's new engine has SCR, so it might meet US emission regulations. They just don't need to offer a fuel efficient truck for CAFE at this point. Credits earned from Prius sales let them sell the FSP Tundra right now.

    Thanks for that. I didn't know the Tundra was getting the Cummins diesel. Toyota's hybrid system is efficient but I don't think it's suitable in its current application in light duty pickup trucks. It'll need to make some compromises (like swapping out the PSD for something a bit more robust for towing duty). In the Tacoma or Tundra's case, a diesel hybrid may make more sense. Torque for towing, diesel engine for highway efficiency and EV for city/crawling efficiency. A plug-in diesel hybrid would be better - the battery can be used as auxiliary power and while not ideal, the whole vehicle can be used as a diesel generator if the owner is in the middle of nowhere.

    Having towed 1,750 lbs over 600 miles in a 2010 Prius, the problem is lack of rear wheel drive for towing. The tongue weight offloads the front drive wheels. Stopping is not a problem as much as being able to accelerate in marginal conditions.

    Which is partly why Toyota only has official tow ratings on the AWD hybrid SUVs in most of the world. Even then, they don't rate it up to what the less powerful FWD ratings. The same was even true with GM's two mode hybrids. Under pressure from the Australia branch, Toyota gave the Camry hybrid a tow rating for that market, and it is lower than the rating of ICE models in its segment.

    I am disappointed in cars for the US market(do Canadian models get ratings?) getting a zero rating while they can tow in other countries. But Toyota even says no towing with their hybrids in those tow friendly countries. Perhaps it is a case of being overly cautious with the HSD drive train. Plenty have towed with their Prius. Those that do, and plan too, just need to be aware that liability will fall on them if something goes wrong.

    It might have to do with culture. Australians have no problem towing a 5th wheel if they need to carry more than what their vehicle is capable of. Americans just tend to buy a bigger vehicle rather than tow.

    Toyota Canada does not show the towing rating for the Camry Hybrid. The HiHy is rated at 3,500lbs.

    No, Americans just buy a bigger vehicle for when they need to tow a small trailer. ;) It could be more stringent requirements for the tow rating, the fear of litigation had manufacturers remove it, or cheap gas made upselling a larger vehicle for towing easier.

    The V6 FWD highlander is rated 5000lbs. IIRC, the HyCam has a 500lbs or even lower rating in Australia. Our 2001 Sable is rated up to 1600lbs.

    Yes, when it comes to towing, rear wheel drive can not be beat. As for buying a large ctruck for towing: always buy more truck than you need. Truck weight, engine torque, wheel base, braking system, and overall vehicle stability with reserve power and braking are a must have. It IS better to have a truck with the extra capacity than have one that is going to be dangerous and NOT up for the task of towing and hauling. An underated truck will wear out much more quickly than one properly suited for the job.

    I may see a trailer once or twice a year. More often, it's a rooftop carrier. I'm talking about a trailer box though, not one to haul water skis or boats. (there are definitely more of those near the recreational lakes)
