It looks better than the current gen, but then I've also never been a fan of the current gen styling.
Going to be interesting to get official numbers from that 3.5 TTV6. If it's the same 409/479 as the Land Cruiser, then it still lags a bit behind Ford's 3.5 which is capable of 400/500 in the standard model, 450/510 in the Limited/HO, and 430/570 in the Powerboost.

I think you’re absolutely correct. I’m puzzled as to why Toyota keeps ignoring putting their excellent twin turbo diesel in the Tundra. The GM straight 6 3.0 Duramax is a phenomenal engine. It gets great mpg; has a smooth, linear power curve & it’s super quiet. Toyota hasn’t had a diesel in the consumer American market in decades & that’s just dumb. A 6 cylinder turbo diesel has enough low-end torque to keep most folks from flogging & wasting fuel. I could possibly ignore some Tundra ugly with a silky Toyota twin turbo diesel. That would be the best of all worlds, power, smoothness, good mpg, reliability & macho looks.

Engineers and designers might have to verify this, one reason I suspect for those high hoods and cavernous underhood space is tho allow enough cooling air to flow around the engine to cool those big V8s making several hundred HP and ft-lbs. of torque. While the majority of engine-cooling comes s from the formal radiator/water-pump/coolant system, a significant amount also comes from air that can flow around the hot engine block. I've reviewed a couple of Nissan products in the past (not the Titan) that ran somewhat on the warm side (more than average) because the engine and other components were simply packed in too tightly under the hood, and air didn't circulate freely.
One might (?) argue, with some justification, that there are some V8s, such as those in high-performance cars, that run fine, with average underhood temperatures, without being stuck down inside of Mammoth Cave underhood. True, but those V8s are generally tuned differently from truck-powerplants, have different HP/torque-curves, and produce heat in different ways, under different conditions, than sports cars and high-performance cars.

Believe it. Its a styling trend in the pickup segment, hence why the other full sized pickups do the same thing.

Playing devil’s advocate for a moment; my Camaro is a 6.2 V-8 that’s neatly sandwiched into the engine compartment. It cools just fine. The Chevy 2500 HD also has a 6.2 V-8 that sits in what looks like the Grand Canyon of engine compartments. I can drive the Camaro all day in 105 degree heat at 75-80 mph & have a cool running engine getting 26 mpg without cylinder deactivation. I realize the Chevy 2500 HD also offers a 6.6 V-8 Duramax diesel engine, but it’s not crazy larger than the 6.2. Most of the space is wasted. They use active grill shutters to close off the engine bay during certain conditions. I’m not convinced that cooling has anything to do with a Godzilla-looking front end.

diesel has a huge amount of headaches, yes it makes higher mileage but the fuel cost is higher. The engine costs more up front and the maintenance is higher. Diesel parts are more expensive when they break and you have to deal with filling up DEF. They are usually a $3k option, can buy a lot of gas for 3k. Diesel is good if you tow often. Its even worse on the HD truckks, the diesel option is $10k over a gas engine

Please consider, however, most owners aren't towing most of the time. Too, most owners aren't into the boost most of the time. The concept for the V6tt is that you can drive the truck economically most of the time, but have power in reserve when you need it. Additionally, a drop in mileage during towing affects all engines.

I addressed that in an earlier post......don't know if you saw it. V8s in high-performcnce cars like the Camaro tend to be tuned differently from V8s in work-trucks. They have different a different emphasis on their function, different torque/HP curves, and different ways of building up heat.

But in staying on topic somewhat, I still don’t understand Tundra’s giant engine compartment that is primarily going to have a twin turbo V-6. Very few models will have the V-8 & I would expect that the V-8 will be phased out completely in the next year or two. I’m sad that this truck is so ugly. I was really looking forward to something special!
