The latest news regarding the upcoming Honda/Acura NSX has the supercar making closer to 600 horsepower than the previously reported 550hp from its 5.5-liter V10. The other important piece of news is that the engine will feature Honda’s cylinder deactivation system, called Variable Cylinder Management (VCM), which would allow it to run on one bank of cylinders during low-load conditions.

When firing on all 10 cylinders, the engine will make about 434lb-ft of torque, or pretty much the same as Nissan’s GT-R. Like the GT-R, the power will flow through all four wheels, say Japan’s Holiday Auto reports. The engine will be related to the 4.5-liter V8 that will power the next-generation Acura RL, although it will be a 90-degree V10 as opposed to the 72 degrees of separation between the V8’s banks. To reach its output, the V10 will rely on lightweight connecting rods and pistons that are fully balanced along with the rest of the rotating assembly. A dry-sump lubrication system will keep the pricey bits oiled during high-g maneuvers.

This engine may also appear in a high-performance version of the RL (RL-F?), the reports suggest. This would be easier since the two will be assembled at a dedicated line in a new Honda plant, and share certain parts.

The true second-generation NSX is also expected to weigh in at about 3,300lbs, which would give it a much better power-to-weight ratio than Nissan’s mind-blowing GT-R. Between Honda’s Super Handling AWD system and aerodynamic tricks lifted from its experience in Formula 1, the NSX should also trump the GT-R’s impressive handling. Like in the original NSX, the wheel and tire package will be staggered, with 255/30R19 Bridgestone RE070R’s up front and the same tires in a 295/35R20 dimension in the rear.

The NSX should beat the GT-R as it will be priced well north of it, competing at the price level with the likes of Jaguar’s XKR and Aston Martin’s Vanquish. The equivalent retail price is expected to be the equivalent of about $150,000.
