Default Why No Diesel Engine for 2010 4Runner?

It really is too bad of Toyota to withhold their excellent 3L Turbo diesel engine from Americans and Canadians. This engine is available elsewhere in the world, for example in Australia, on vehicles which are essentially similar to the 4Runner. Torque of the diesel is actually a little higher than that of the 4L V6, though HP is less. Driveability and acceleration are reported by owners as excellent and fuel consumption is reported as being almost 1/3 less than that of the gas engine - a dramatic and highly desirable improvement for the 4Runner which north american customers would very much appreciate!

This diesel engine already meets stringent emission standards required in other countries, and it is hard to imagine that it would be that difficult to get it adapted for USA and Canadian standards. Because the torque of this 3L diesel engine is only slightly higher than that of the 4L gas engine, I would expect that no significant upgrading of the transmission drivetrain would be required, minimizing potential additional costs associated with a diesel engine. This 3L diesel engine would be a much better option than the current 2.7L 4 cyl gas engine option with its much lower torque which offers only marginally improved economy and must work hard to move such a heavy vehicle.

Come on Toyota, when are you going to stop withholding advanced efficient clean diesel engine technology from north americans? - engine technology which is already provided to thousands of customers in many other countries.

There just doesnt seem to be the market to support it in the US....otherwise they would have one here..... at this rate we still cant get a full size diesel....

I am not sure why we are not being allowed a turbodiesel 4Runner, Tacoma, and Tundra in this country. A modern turbodiesel in the 3.5L-4.0L range would be perfect for the 4Runner and Tacoma, and a 4.5L-5.0L would be perfect for the 1/2 ton Tundra. Figure the smaller unit with compound turbocharging or a twin scroll or variable vane turbo should be good for around 270hp and 450lb-ft, and the larger unit for a 1/2 ton Tundra with similar technology should make an easy 320hp and 500+lb-ft of twist. Both would put out great performance for towing or hauling, and should easily return over 20MPG highway.

The downside is cost, but there are tax credits available for diesels, so why not!?

The best I can figure it is the gov. and the US auto makers. GM has a 25% stake in toyota. The big truck market is the only
thing they have left. My friend snuck a real Smart Car in from canada a few years back. 3 cyl. turbo diesel that got a real
100 mpg. Remember in any barrel of crude their are only so many gallons of oil, the rest is made into gasoline and a few other
products. So maybe we are being hosed to keep the price of gas up and the cost of diesel down a bit? I can tell you I won't
buy another gas powered truck. The mileage is terrible if you pull anything heavy and not that good when empty.
