Lexus V35A FTS Hybrid specs: 3.4L (207.5 ci) 6-cylinder, 85.5 x 100 mm (3.3661 x 3.9370 in) bore and stroke, 10.5:1 compression. Rated 437 hp. DOHC.
The Lexus V35A FTS Hybrid is undersquare — the 3.937" stroke exceeds the 3.3661" bore by 14.5% — a layout that trades peak RPM for leverage and torque low in the range. The 3.937" stroke puts mean piston speed at 4,000 ft/min around 6,100 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 34.6 ci (567 cc).
10.5:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.
Factory fitments include the Lexus TX 550h+, Lexus LS 500h.
