Lastly, from my experience working at a supplier for domestic OEM, powertrain teams are given fuel economy, power, refinement, and cost targets to meet overall program goals.
While Ford has its own financial and management issues (see CD6 program spec/timeline/cost slip), IMO Toyota's powertrain team have failed to meet their targets
While thermal efficiency is excellent in Dynamic Force family (40%+ ... their Mazda investment paid off), each powertrain 'package' has shortcomings:
Tundra hybrid is fine with the "Toyota reliability tax".
Though it has worse acceleration, fuel economy (3MPG), payload (200lb), tow (700lb), and cost performance ($5k) than Powerboost F-150, it seems fairly reliable (so far immune from issues affecting gas-only models) and cheap to own with NiMh battery.
Tundra gas is really bad. Took 11 years to release a TT V-6 that's worse in every way than Ford's MY11 3.5 Ecoboost.
It combine bottom end issues with performance (HP and TQ) and fuel economy deficit, though the transmission is probably more dependable than 10R80.
In midsizers like GX, the V35A is this is compared to Bronco/Ranger 3.0T which has 70 more HP for the same fuel economy.
Tacoma hybrid variant of T24 is great for midsizers but just 'ok' overall.
Although it has worse fuel economy and power than F-150 Powerboost, it was designed to a different cost target, compares well in its class and seems fairly reliable so far.
In midsizers (Land Cruiser), this is the midrange powertrain comparable to the Ford and GM 2.7T which both have less factory HP and fuel economy.
Tacoma gas-only variant of T-24 seems like a miss.
It compares poorly to Ford 2.7T V6 and my complain about the insane NVH is shared with reviewers.
With similar EPA fuel economy, it's down on power to the 2.7T (279 vs 310 stock or 355 warrantied tune, TQ is similar)
When compared to the Ford 2.3T (which I think has really poor driveability), stock power/fuel economy are comparable BUT
... Tacoma NVH is so bad that even the Chief engineer of Tacoma said they detuned the engine to mate it with a manual transmission in the Tacoma due to crank shaft hammering lmao.
Though NVH doesn't seem to deter buyers though since even RX sales numbers are up, you really wanna buy a powertrain package that had to be detuned?
Ford on the other hand is offering a warrantied 2.3T tune for 330/385lbft ... paired to Bronco 7MT.
