We're still just over three months away from the long-awaited debut of the fifth-generation Toyota Supra at the 2019 Detroit Auto Show, but a wealth of new information about the Japanese sports car has been uncovered thanks to a leaked BMW parts catalogue posted on the SupraMKV forum. In case you're wondering why the Supra is featured in a BMW parts catalogue, the car was jointly developed with the all-new Z4.

According to the guide, the reborn Toyota Supra will be sold in three flavors. The base model will use the BMW Z4's 20i trim fitted with an engine dubbed the B48D, which is believed to be a BMW-sourced 2.0-liter four-cylinder engine that delivers 262 hp. It will be sold exclusively in Europe in left- and right-hand drive configurations.

Moving up the range, the 30i has a B46D unit that will be sold across Europe and the US, while the range-topping Supra 40i will have a B58C 3.0-liter six-cylinder engine that is expected to produce around 340 hp. All three engines are connected to an automatic transmission listed as GA8HP51Z. This suggests it will be an eight-speed setup, which supports rumors that the new Supra will not be available with a manual transmission.

The guide also includes diagrams showing what appears to be an outline of the production Supra, which has so far only been shown as a concept or camouflaged prototype. It also provides a detailed overview of the interior, showing a fully-digital gauge cluster, a BMW-sourced three-spoke steering wheel and gearshift, and sports seats. There's also a stylized "Supra" badge that's clearly a throwback to the old A80 model. You can browse the parts catalogue online for a detailed look at the new Supra.
