Lexus 2UR-GSE specs: 5.0L (303 ci) 8-cylinder, 94 x 89.5 mm (3.7008 x 3.5236 in) bore and stroke. Rated 416-472 hp, 2008–2025. Used in the Lexus IS. DOHC.
The Lexus 2UR-GSE is oversquare — the 3.7008" bore exceeds the 3.5236" stroke by 5.0% — a layout that favors airflow and RPM over leverage at the crank. The 3.5236" stroke puts mean piston speed at 4,000 ft/min around 6,800 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 37.9 ci (621 cc).
It is one of 13 engines in the UR family, sitting between the 281 ci and 346 ci members. 16 factory variants share these dimensions, rated from 416 to 472 hp across 2008–2025.
