A90 Toyota Supra Turbo Six Cylinder Engine Bay Details Revealed Leaked ScionLife.com

BMW B58 turbo-six engine lurks beneath the hood of latest Toyota Supra.

We have known for a while now that the all-new 2019 Toyota Supra, AKA the ‘A90,’ would feature BMW powertrains. Specifically, two BMW-sourced engine options will be available: the B48B20, a two-liter, turbocharged four-cylinder, and the B58B30, a three-liter, turbocharged inline-six. Of course, during the soft unveiling event at Goodwood, we also learned about the wheels, tires, brakes and various chassis components the car uses.

So, at this point, we have a pretty good handle on the mechanicals that underpin the Supra, and what engines will make it go fast. However, now, we have actual engine bay shots, thanks to fan site SupraMKV.com.

As someone with a lot of experience dealing with BMWs, this engine bay has BMW written all over it. Everything from the type of plastics used in the bay to components like the air box, intake, wire loom shields, and coolant overflows are easily BMW-made.

Of course, that’s not a bad thing. After all, current BMW models with B58 engines make 335 horsepower. But there’s more to the story than that. Via SupraMKV, member Guff had a lot of insights on the engine bay. Guff says:

“Okay so upon closer inspection, we have:

  • The same water-air intercooler system built into the intake manifold as the B58. I’m saying this because of the size of the manifold and the water lines, which are very similar to that of other B58 cars.
  • The same engine accessory layout and harness routing.
  • The B58s new massive water pump (which is pulley driven not electrical like the old N55).
  • The intake had a slightly different resonator and airbox, but same routing.
  • The engine is not fully behind the strut towers, so likely not behind the front axle (unless the caster is crazy :/).
  • The motor doesn’t seem to be placed extremely low in the engine bay, although the hood line is fairly low, but it begs the question “How tf does this car have a lower CoG than an 86!?” The majority of the heavy components in an 86 are barely higher than your knees, here we have a big intake manifold full of water at waist height. Remains to be seen!
  • Can’t see the block so can’t see the material type.
  • Judging from the layout this also means that we have BMWs rear facing Valvetronic system, but that’s a guess as I can’t actually see it.”

A lot of useful info here. So, what do you think about the BMW-Toyota Supra?
