Body

Aluminum Unit-Body Construction

  • World's first mass produced all-aluminum body
  • Unit body weighs only 462 lbs - 40% less than steel
  • Incorporates unique high-strength extruded-aluminum side sills
  • Unique heat treatment ensures surface hardness
  • Highly corrosion resistant
  • High torsional and bending rigidity

Cabin-Forward/Long-Tail Design

  • Best-in-dass visibility - 312 degrees
  • Significantly improves aerodynamic balance
  • Provides optimum occupant and component layout
  • NSX-T features and easily removable roof panel for open-air driving

Powertrain

VTEC System

  • First application in U.S.
  • Unique Variable Valve Timing and Lift Electronic Control (VTEC)
  • Uses two different cam profiles to improve low-end torque and high-end power
  • Boosts engine performance to more than 90 hp per liter

Variable Volume Induction System

  • Improves power and torque by optimizing air induction at all rpm

Direct Ignition

  • Eliminates distributor
  • Each plug has its own ignition coil, similar to a racing engine
  • Delivers stable high voltage to spark plugs

Titanium Connecting Rods

  • World's first use in a production car
  • Stronger than steel, lightweight - saves 190 grams
  • Reduces reciprocating mass for high-rpm engine operation

Transmission

  • All-new compact, lightweight, close-ratio 6-speed manual transmission
  • Formula One-inspired SportShift system for automatic transmission models allows for fully automatic or manual shift operation

Torque Control Differential and Torque Reactive Differential

  • Unique limited slip differential designs
  • Improves stability in crosswinds

Chassis

All-Aluminum Suspension

  • Aluminum 4-wheel double-wishbone design
  • Forged-aluminum suspension arms for strength, low unsprung weight
  • Front suspension utilizes unique compliance pivot for ideal suspension geometry and ride quality
  • 44lbs (20 kg), lighter than steel

Four-Channel Anti-Lock Braking System (ABS)

  • First use in U.S.
  • Provides more precise independent braking control over each wheel

Traction Control System

  • Enhances performance over wide range of conditions rather than just low friction surfaces
  • System can be shut off manually by driver
  • Drive-by-wire throttle control enhances Tes deceleration stability

Electric Power-Assisted Steering

  • First of its kind on American market
  • Electric variable power-assist uses electric motor rather than hydraulics to reduce steering effort
  • Reduced weight
  • Does not take power away from engine to operate hydraulic pump

Custom-Designed Tires and Wheels

  • Specially developed wheels and tires: Front - 215/45ZR 16 tires, 16 x 7 JJ forged alloy wheels; Rear - 245/ 40ZR 17 tires, 17 x 8.5 JJ forged alloy wheels
  • Unidirectional tires specific to each comer of the car
  • Different compounds used front and rear
  • Lightweight, forged aluminum-alloy wheels reduce unsprung weight by 19.81bs (9 kg) over cast wheels

Drive-By-Wire Electronic Throttle System

  • Improves throttle response and acceleration feel
  • Improves performance of automatic cruise control and traction control system

Interior

Dual Air Bags, Automatic Seat Belt Tensioners (Supplemental Restraint System)

  • Compact air bag design allows use in small steering wheel space
  • Electrical connectors are gold-plated to enhance conductivity and provide corrosion protection and reliability
  • Automatic seat belt tensioners help to hold occupants in place

Aluminum Seat Frame

  • First for a production car
  • Entire seat frame made of lightweight stamped aluminum
  • Has one-third fewer parts than steel seat
  • Seat rails made from aluminum extrusions

Highly Efficient, Heat-Absorbing Green Glass

  • Helps keep the effects of solar loading on interior temperatures at a minimum in hot weather
