There were a lot of talk about the Subaru BRZ possibly getting a turbocharged engine but Subaru has already shot that down. While Toyota did not say anything about the Toyota 86, it is safe to say that it too will not be getting a turbocharged engine for 2018.
However, there were speculations saying that we might see a Subaru BRZ STi model in the near future. This was after Subaru announce that they are looking to expand their STi lineup. However, Subaru has also stepped out to shot down that rumor.
It looks like they plan to keep the Subaru BRZ as simple as they can and the Toyota 86 will be following it as well. The 2018 Subaru BRZ and Toyota 86 will continue to offer 200 to 205hp engine with their 2.0 liter naturally aspirated four-cylinder boxer engine.
Fans are hoping that Subaru and Toyota will change things up in the next gen model but we will have to wait and see.
