I’m not sure how many “debuts” the new Acura NSX has had, but we seem to be finally nearing the day when the hybrid supercar enters production. Just exactly when production will begin, we don’t know yet, but Acura executives did deign to release a few more tech details at the 2015 SAE International World Congress, confirming the engine size and highlighting the world’s first use of ultra-rigid “ablation” casting.
You can read the full list of new tech details below, but some highlights include conformation of the 3.5 liter twin-turbo V6 that will serve as the heart of the NSX’s powertrain, paired with a hybrid drivetrain for maximum performance and efficiency, churning out about 550 horsepower. Acura makes a big to-do about ablation casting, which allows for more rigid, impact-absorbing crush zones. Not exactly the most exciting aspect of a hybrid sports car one could discuss, but important none-the-less. Hopefully they’ve sorted out their little combustion problem too.
The automaker does wax poetic about the new Sport Hybrid Super-Handling All-Wheel Drive system and its ability to provide superior torque vectoring, and the original NSX was more at home on a road racing track than the drag strip. Pricing is estimated to be in the $150,000 when it finally, finally goes on sale later this year. ANd of course there’s still hope for a pricier Type-R version eventually as well.
– The all-new NSX employs 10 air-cooled heat exchangers responsible for cooling the front twin-motor unit (TMU), twin-turbo V6 engine, rear direct-drive electric motor and 9-speed dual clutch transmission (DCT).
– The all new, twin-turbocharged 3.5-liter V6 engine at the heart of the Sport Hybrid SH-AWD power unit requires the greatest cooling and receives it through three radiators: one center and two side units to get maximum airflow volume and efficiency. The center radiator is tilted forward 25-degress, allowing the largest, optimized configuration that best utilizes the inherent pressure gradient while maintaining the strict low center of gravity targets of the NSX’s Advance Sports Package.
– Condenser and power drive unit (PDU) coolers are efficiently packaged in front of the center engine radiator.
– The TMU is cooled passively through strategic use of air in the front motor room and by a heat exchanger mounted in front of the right engine sub- radiator.
– The 9-speed DCT is cooled by two heat exchangers, one mounted in front of the left engine sub-radiator and the other in the engine compartment.
– Twin-intercoolers located in the signature side intakes are used to cool the intake air charge.
– Supercar Aerodynamics NSX achieves top-class aerodynamic balance and supercar aerodynamic downforce without the use of active aero.
