The Japanese brand might not be done with V8s, as it turns out.
Toyota isn’t focusing on V8s as much as it used to. The current Lexus LS is a V6-only affair now (bolstered by either turbochargers or hybridization), and the next-generation Toyota Tundra is rumored do ditch its husky 5.7-liter V8 in favor of a downsized twin-turbo V6 as well. However, we’ve heard rumblings of a twin-turbocharged V8 coming to a performance-oriented Lexus product, as evidenced by a recently discovered patent from 2020.
Toyota filed the claim (first discovered by a member of the GR86.com forum) in September 2020, well after we heard that development of the Lexus LC F had stalled. The patent features many revealing drawings, betraying the engine’s hot-V layout, with both turbochargers residing in the valley between the cylinder banks, reducing lag and improving throttle response. Details within the patent also suggest that a single-turbo layout is also possible, so Toyota could theoretically offer two different versions of the engine for varying power and efficiency requirements. We’d expect the twin-turbo to boast at least 600 horsepower (447 kilowatts).
Merely filing a patent doesn’t guarantee that Toyota will offer the engine in any of its products, but it still seems likely that it should show up in the next generation of Lexus’ performance vehicles, including the rumored LS F, LC F, and IS F. That would give the BMW M–rivaling sub-brand a high-tech flagship engine, and it would also explain why the current IS 500 isn’t a full-blown F model in spite of its prodigious 472 hp (352 kW) – Lexus wanted to leave some room at the top of the lineup for the incoming turbo eight.
