Lexus 2GR-FXE specs: 3.5L (211.8 ci) 6-cylinder, 94 x 83 mm (3.7008 x 3.2677 in) bore and stroke, 13:1 compression. Rated 259 hp. Rod ratio and piston speed.
The Lexus 2GR-FXE is oversquare — the 3.7008" bore exceeds the 3.2677" stroke by 13.3% — a layout that favors airflow and RPM over leverage at the crank. The 3.2677" stroke does not reach 4,000 ft/min of mean piston speed until about 7,350 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 35.3 ci (578 cc).
13:1 on aluminum heads is high for a production gasoline engine; running a ratio like that on pump fuel depends on chamber design and fuel delivery rather than the number alone.
Factory fitments include the Lexus RX 450h, Lexus GS 450h, Lexus LS 600h and 1 other.

| Advertised HP | 259 hp |
| Bore/stroke character | 1.133 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves |
|---|---|
| Mean piston speed at 6,000 RPM | 3,268 ft/min — conservative for a street engine |
| Displacement per cylinder | 35.3 ci |
| Static compression | 13:1 — high enough that pump premium or better is normally required |
