Is IS350 F Sport a V-8?
No—the IS350 F Sport is powered by a 3.5-liter V6 and does not use a V-8.
To understand why this matters in the context of Lexus’ IS lineup, it helps to know how the F Sport badge is used and how engine choices have evolved across generations. The F Sport trim adds sport-tuned suspension, brakes, and styling cues rather than a larger engine, and true V-8 power in the IS family has generally appeared in the higher-performance variants such as the IS F and the more recent IS 500 F SPORT.
Where the IS350 F Sport fits in the lineup
The IS350 F Sport sits in the mid-range of the Lexus IS family, offering a balance of luxury, handling, and responsive V6 power. The engine configuration is distinct from the genuine V-8 variants, which are reserved for higher-performance models.
Key engine configurations in the Lexus IS lineup
The following overview clarifies which IS variants use which engines and why the IS350 F Sport is not a V-8.
- IS 350 / IS 300 lines: 3.5-liter V6, producing roughly 306–311 hp depending on year and market.
- IS F (high-performance variant): 5.0-liter V8, about 416 hp, designed for track-focused performance.
- IS 500 F SPORT (modern high-performance variant): 5.0-liter V8, around 472 hp, introduced as a V8-powered successor to the F Sport line.
Bottom line: If you want a V-8 in the IS lineup, choose the IS F or the IS 500 F SPORT. The IS350 F Sport itself remains a V6-powered model.
What to consider when shopping
When evaluating an IS, confirm the exact model year and market, since Lexus has updated engines and trims across generations. If engine displacement is a priority, note that the IS350 F Sport delivers V6 performance with sport-focused handling, while the V8 variants—IS F and IS 500 F SPORT—offer higher horsepower and different tuning characteristics.
Summary
The IS350 F Sport is not a V-8. It uses a 3.5-liter V6, while true V-8 power exists in the IS F and the more recent IS 500 F SPORT variants. The F Sport badge signifies performance-oriented handling and styling rather than a larger engine, though higher-end models do offer V-8 options for those seeking outright power.
