Will the Toyots badge alone make this thing more reliable? Bet Ron says yes. ![Cheesy :D](https://www.autos.ca/forum/Smileys/CarTalk/cheesy.gif)
No, I've said the opposite, actually.
And is one of the reasons I suspect Toyota de-tuned the I6 to 335HP vs BMWs 380HP.....didn't meet their reliability/longevity criteria during testing.
And if it's like every other BMW I6, it's going to need main bearings guaranteed at some point.
Fortunately, they'll sell so few it shouldn't reflect too bad on the brands overall reliability. ![ROFL :rofl:](https://www.autos.ca/forum/Smileys/CarTalk/rofl9wz.gif)
But from a Supra lover perspective...will you be able to pull 600+ HP with just bolt ons from the BMW platform and have years of trouble free use on even high mileage cars/severe use cars? Ummmmm.....NO!
They didn't detune the engine. 335 hp is how much the B58B30M1 makes, and it's used by the Euro Z4 and M340i, as well as by all X5 and X7 40i models.
The more powerful Z4 uses the B58B30O1 only in countries that don't have EU emissions standards. Same with the M340i.
Could be a cost thing, since they would have to use that engine in the EU anyways. One less build combination.
