Reports have Lexus tweaking an extra 12 horsepower and 4 lb-ft of torque out of the Yamaha-sourced 417-hp/372 lb-ft, 5.0-liter V8 for an increased output of 429 hp and 376 lb-ft of torque. A modest increase, it would seem, until you look at the targeted 220-lb weight reduction. And as we all know, a little more power unburdened by significantly less weight is a winning formula. Just ask the likes of the Ferrari 430 Scuderia, Lamborghini Gallardo SUperleggera, Porsche 911 GT2 et al.
The rumored price of admission? A whopping 11 million yen in Japan, compared to the 7.7 million yen for what suddenly looks by comparison like a rather ordinary "standard" IS-F. Pursuit of Perfection, indeed.
