What is the top speed of the Lexus F?
There isn't a single top speed for the Lexus F lineup; each model is electronically limited to around 270 km/h (about 168–170 mph), with exact figures varying by model.
The question covers multiple cars branded as Lexus F (IS F, GS F, RC F). Speeds depend on the specific model and market, but the overall approach is to cap performance at roughly the same ballpark, subject to model-year adjustments and optional packages.
Lexus F models and their top speeds
Below are the production models commonly associated with the Lexus F division and their official or commonly cited top speeds.
- IS F: electronically limited to 270 km/h (approximately 168 mph).
- GS F: electronically limited to 270 km/h (approximately 168 mph).
- RC F: electronically limited to 270 km/h (approximately 168 mph).
Note: These figures refer to standard production variants. Performance-oriented packages or regional tuning can affect the exact limit, but the general cap remains in the 270 km/h range for these models.
Model details and context
IS F specifics
The IS F marked Lexus’s early foray into high-performance sedans, powered by a 5.0-liter V8 and rear-wheel drive. Its top speed was officially limited to about 270 km/h (168 mph), aligning with other early F models’ performance targets.
GS F specifics
The GS F offered a more luxury-oriented platform with a high-output V8 and track-ready tuning. Its electronically governed top speed matched the lineup at around 270 km/h (168 mph), reflecting its performance intentions while balancing comfort and daily usability.
RC F specifics
The RC F combined a potent V8 with a coupe silhouette, again capping at roughly 270 km/h (168 mph) in standard form, consistent with Lexus’s F-brand speed limiter approach for these variants.
LC F concept and other notes
The LC F was presented as a high-performance concept and study, not a production model. Because it was not released as a standard road car, its official top speed was not published as a production specification. The production LC 500, by comparison, is limited around 270 km/h in most markets, aligning with the broader F-family philosophy.
Summary
In short, there isn’t a single “Lexus F” top speed. Across the IS F, GS F, and RC F, the common ceiling is about 270 km/h (168 mph) due to electronic speed-limiters and engineering choices. Specifics can vary slightly by model year, market, and optional equipment, but the top-speed target for the Lexus F lineup remains in the same general range.
