Tundra Could Get Diesel Engine

[kevinj]

I'd love to see the diesel engine that they put in the Land Cruisers over seas end up in the Tundra. Outside of emissions I couldn't imagine this being a complicated thing since the 5.7L engine is already in the Land Cruisers and they put a diesel in them. I wouldn't buy one if they were looking for a torque monster, but if they had one that would still pull the same 10,000 pounds, but have the efficiency of the diesel to improve range... We'll that would be just perfect!

My guess is 2016-2017 when Toyota makes an agressive move with different motors and such.

not likely the landcruiser engine would be allowed to tow that 10,000 pounds. the 4.5 D4D diesel engine is ( at least in the netherlands ) restricted to tow 3.500 kilo / 7,716 pounds and averages 22.3 mpg...

I think it might get close. The land cruiser here is limited to 8200 lbs and is equipped with the 5.7L. I wonder what they'd get out of 4.5 D4D in a Tundra. I'm thinking this sounds like a great option!!!

i think the 4.5 diesel engine CAN easily pull 10K pound, i have driven the 3.0L 4 cylinder diesel Landcruiser that already had a towing capacity of 3.500 kg / 7,716 pounds and it towed like a charm... ( it averaged 20 mpg ) diesel stands for torque, tons of torque...

if a diesel tundra would become available, i'd seriously consider it..!!

Yes, 1000 ft-lbs.

I'd think the 4BT Cummins would be a nice motor for half tons. A lot of folks have already put them in pickups, including Ford Rangers. Pretty easy to get 300 hp, I believe. BTW, the Dodge transmissions are fine, if - you increase line pressure to the clutches. There is a guy from Iowa, I believe with a 99 1Ton Ram with 1.6 million on his CTD Ram, never overhauled motor, did trans at 300,000 miles and modded the trans for more line pressure , hasn't had a problem since. Shifts will be firmer, not a bad thing. I modded mine. Cummins are really sweet, would be interesting if Tundra built a 3/4 ton with one. Also the 6 speed manual's are very tough.

Oh please, please, please! I am a huge diesel advocate and know that Toyota can do it. Their diesel offerings overseas are truly awesome and hopefully wont require too much capital to meet US requirements.

Sounds to me like that 4.5 Landcruiser diesel in the tundra fits smack in the half ton pickup teritory.
I believe that with an eight speed or more the 10k towing capacity would be atainable and still able to perform well. Perhaps not as well as tundra 5.7 , that is a hot rod truck and tows well too.
Diesels are not for everyone though. I had F350 dually 7.3 with full Banks big head , turbo , intercooler,. I never found a grade so steep it would not climb faster than was safe to go and that with a total weight of about 13k.
I now have Tundra DC long bed and tow 7.5k trailer , doesn`t have the power on steep grades but there is more weight drives better fuel is cheaper mileage is same towing and better not and I like the truck a lot better.

CUMMINGS!??

Toyota could make a splash in the market by offering a diesel option in a half ton. I am still saying it is not going to happen and if I owned Toyota, I wouldn't do it. I love my truck, but America seems to still love the Big 3 a hell of a lot more. Low volume sales would hold me back before I would introduce a diesel into a half ton truck, or even to try to make an HD version of a Tundra. If Toyota is smart, the engines that they put in the Tundra need to follow the plan that Toyota has set out for their engines. Direct injection, 8 speed transmissions, and possibly the introduction of turbo'd engines would be a smarter move.

A diesel would be nice, but in the process revert the trucks back to a solid front axle and give us true limited slip or at least a rear selectable locker. As well as a manual transmission option to truly get the best fuel economy. I'm not so sure about a CVT transmission in a truck, I drove a rental car a few years ago that had a CVT and it ran at a pretty high RPM all the time so they aren't exactly the greatest transmission that people are trying to claim they are, they keep RPM's way too high to get any economy out of them. My ATV I used to have came with a CVT, and so did my utility vehicle both worked ok for that, but I'm kind of leery about one in a truck that's meant for hauling and towing.

Aisin has an 8 speed transmission out that matches up to the current 6 speed configuration.
