Toyota surprised gearheads at the 2025 Japan Mobility Show by confirming the V8 will remain in its lineup. The caveat: the next generation abandons the current naturally aspirated character in favor of forced induction. Lexus could also receive the new eight-cylinder for a future sports car.
Toyota and Lexus pledge: a new V8 is coming
At the Tokyo event, Toyota engineers signaled that an eight-cylinder engine is still part of the company’s future plans. Sources who spoke with Takashi Uehara, Toyota and Lexus chief powertrain engineer, say the automaker is developing a fresh V8.

The headline: the V8 is not dead — but it will evolve. That shift reflects both market realities and engineering trade-offs.
Why the V8 survives despite tightening rules
Several forces pushed Toyota to keep an eight-cylinder option alive. Regulatory pressures have eased in some regions. Demand for electrified cars has not fully replaced appetite for internal combustion.
- U.S. regulatory rollbacks reduced near-term compliance cost pressure.
- Consumer uptake of EVs remains uneven in many segments.
- Performance buyers still prize V8 sound and character.
Combined, those factors reopened the door for another V8 program focused on efficiency and power.
What’s changing: naturally aspirated to twin-turbo
The next V8 will give up the high-revving, naturally aspirated layout that defined recent Lexus engines. Engineers plan to use twin turbochargers to hit modern power and emissions targets.
That means a different sound, delivery, and engineering philosophy. Turbocharging allows a smaller displacement, higher torque at low rpm, and better fuel economy under real-world cycles.
Remembering the 2UR-GSE: Lexus’ iconic V8
The outgoing high-performance V8, the 2UR-GSE, earned a lasting reputation. It is a 5.0-liter, naturally aspirated V8 that powered models such as the LC 500 and IS 500 F Sport Performance.
Key traits included a loud, rev-happy personality and Yamaha-tuned top-end hardware. In its final factory tune, it made roughly 472 horsepower and about 395 lb-ft of torque.
For many enthusiasts, its raspy character and high redline were defining features.
Yamaha’s hand in the old V8 — and what may change
Yamaha played a central role in the 2UR-GSE’s peak performance. The company contributed camshafts, a tuned intake, lightweight titanium valves, and a bespoke head assembly.
- Raised compression and aggressive cam timing produced a 7,300 rpm redline.
- Intake and valve work helped deliver sharp throttle response.
- Yamaha’s input made the motor feel more like a race-bred unit.
It’s unclear whether the same level of external tuning will carry over to the turbocharged successor.
Possible applications: Lexus sports models and beyond
Lexus showcased a Sports Concept at the show. Engineers hinted the new V8 could appear in that car if it reaches production.
Other candidate models include:
- A successor to the LC 500 — a luxury grand tourer with a sporty edge.
- A new halo supercar that could follow the V10‑powered LFA.
- Performance models from Toyota’s GR division, which is said to be developing V8 projects of its own.
Expect multiple applications and tuning levels for different roles.
Technical clues: displacement, power, and modularity
Rumors suggest the new V8 sits around 4.0 liters and uses twin turbochargers. Early estimates put output at well over 500 horsepower in high‑power trims.
Toyota appears to be designing the V8 as part of a modular family of engines. That approach lets shared technologies crossover between small, high-performance turbocharged engines and larger V8s.
- Shared tech could include turbo architecture, electronics, and emissions controls.
- Modularity lowers development cost and speeds validation for multiple models.
- Engine variants could be tuned for daily drivability or track-focused output.
Two variants likely: mellow and muscular
Uehara indicated Toyota is preparing multiple character choices for the V8. One version would favor refinement and ease of use. Another would maximize power for halo cars.
This dual‑variant strategy lets Lexus offer a GT-style V8 and a higher-strung supercar unit. Both could share core architecture while differing in boost, cooling, and internals.
Emissions strategy: advanced ICE without mandatory hybridization
Uehara suggested the new V8’s efficiency may be high enough to meet emissions rules on its own. That would reduce the need to force a plug-in hybrid layout for compliance.
Still, Lexus may offer electrified pairings as options. Plug-in or hybrid versions could help meet corporate fuel-economy targets and appeal to buyers seeking lower emissions.
What enthusiasts will miss — and what they might gain
Purists will grieve the loss of the naturally aspirated scream and the responsive, linear powerband. The Yamaha‑tuned 2UR-GSE offered a visceral experience hard to mimic.
On the other hand, twin turbos deliver higher torque, better midrange response, and greater peak power potential. That translates into faster real-world acceleration and more adaptable driving manners.
Timeline and next steps
Toyota has not published a formal launch date. Expect prototypes and more technical reveals over the next few years as the company validates the new architecture.
In the meantime, the market reaction will guide final choices. If demand for performance ICE cars remains strong, Toyota and Lexus can justify broader deployment of the new V8.
