Our preview of the Lexus LS included a short drive of some early engineering mules. Engineers were still finalizing powertrain calibrations, so we can’t comment on the twin-turbo six at this time. But with the optional air springs, the ride is excellent, and the rear-wheel steering helps the LS feel surprisingly nimble without compromising straight-line stability. The steering is satisfyingly hefty and the brake pedal progressive. The original LS won the first comparison test we threw it into in 1989; we’ll find out in another year or so if its latest descendant can repeat that feat.
I just stumbled onto that article, and this particular tidbit caught my eye:
The current 2GR 3.5-liter V6, by comparison, has an 83 mm stroke and a 94 mm bore, with an actual displacement of 3456cc. Building on the conversation in page 4 of this thread, this is yet another piece of evidence that this is an all-new engine family, as opposed to being simply a twin-turboed 2GR. Although actual displacement for the new V6 has not been revealed, an online calculator ( http://www.revetec.com/Calculators/Engine_Displacement_Calculator-2.htm ) suggests it'll be 3444cc, or technically a 3.4-liter V6. BTW, I ran the 2GR's bore x stroke dimensions on the calculator, and it produced the correct 3456cc displacement, so the calculator certainly seems accurate.The engine’s signature, however, is an exceptionally long stroke—100.0 millimeters in an 85.5-millimeter bore—that Lexus claims enables the engine to achieve new levels of thermal efficiency
Yes, hence my comment "building on the conversation in page 4 of this thread" which is where Carmaker1 revealed the engine code.
The lack of visible exhaust outlets in the rear bumper seems to indicate that this may be the LS500h.
