The 5.0L V8 in the RCF and the IS 500 F-Performance is nearing the end of its career
Future F models will likely be powered by hybrid powertrains
These new models could arrive in about 4 years.
Lexus could be going down the hybridisation route for its performance models, according to the brand’s general manager.
This engine was introduced back in 2007 to power the ISF and despite being well liked by enthusiasts, the current wave of electric and hybrid performance models is beginning to make it obsolete.
In order to keep up with times, Lexus will replace it with hybrid powertrains in its performance-oriented models, before going full electric.
According to the brand’s general manager, this change could come in about 4 years due to the product cycle which dictates that the IS, which was modernised for the 2021 model year, will need a refresh in 2026.
No details have been revealed as to what hybrid technology will be used, and there are a few possibilities even when considering only what Lexus currently offers.
It could be a self-contained hybrid system like the LC 500h uses, which combines a traditional hybrid system with a twin-turbocharged V6 engine, or it could be a plug-in hybrid system similar to the one introduced in the new NX 450h+, which is the most powerful and the most fuel efficient NX ever.
If it follows that second path, however, it is expected to receive a more powerful gasoline engine in order to deliver an output that is in the same ballpark as the current V8 powered versions.
