NSX ( FROM BEGINNING TILL THE END )
The intention in creating the Acura NSX, first introduced for the 1991 model year, was to produce a hand-built, exotic, mid-engine sports car that would establish entirely new levels of prestige, performance, refinement, drivability and reliability. The aluminum-bodied NSX defined a new interpretation of the exotic sports car through state-of-the-art, lightweight technology.
The NSX-T model introduced during the 1995 model year, which featured a removable roof panel, broadened the appeal of the NSX. It also succeeded in maintaining the extremely high levels of performance and sophistication established by the NSX coupe. Technological achievements included an optional Formula One-inspired Sequential SportShift' automatic transmission with a unique steering column-mounted electronic shifter; a drive-by-wire throttle system and standard variable, electric power-assisted steering (EPS), a compact and efficient system pioneered in the first-year NSX equipped with automatic transmission.
The 1997 NSX/NSX-T took a giant step forward in performance with several major enhancements - most notably a larger, more powerful 3.2-liter, 290 hp, V-6 engine with a 6-speed manual transmission. Other significant engineering updates included larger brakes and an improved Anti-Lock Braking System (ABS), refinement to the electric power steering system, application of new aluminum alloys for lighter-weight, high-rigidity body panels, adoption of special heat-reflecting window glass and an anti-theft vehicle immobilizer feature.
Beginning in 2002, all NSXs feature a removable aluminum roof panel that can be easily stowed under the rear glass hatch. Also, in 2002, the NSX received a variety of styling enhancements to modernize the car's looks and refinements to the chassis to ensure its competitiveness as a world class sports car. The front fascia of the NSX was updated with a higher hood, and a redesigned front bumper and spoiler. The front headlights changed from pop-up halogen units to fixed position Xenon High-Intensity Discharge (HID) lamps. Other external styling refinements for 2002 included new mesh side air intakes, a trunk lip spoiler, more aggressive exhaust tips and a redesigned taillight configuration. Chassis refinements included a larger diameter rear stabilizer bar, firmer front springs and bigger wheels and tires to enhance the car's dynamic handling characteristics. The enhancements together combined to reduce the car's coefficient of drag from 0.32 to 0.30 and raise the top speed from 168 to 175 mph.
The mid-engined NSX appeared on the supercar market in 1991 and has continued in production for over ten years. Honda had been dominating Formula One racing and decided to continue that domination in the showrooms. In over a decade the NSX has not changed much. Its styling appears to be derived for the mid-engined Lotus Esprit of the 1970's, with its flat but angular styling cues. In February of 1989 Acura introduced a new sports car at the Chicago Auto Show, the NS-X. Its introduction is significant, being the first supercar from a Japanese automobile manufacturer. The name NS-X represented 'New Sportscar eXperimental'.
The design and materials used on the NSX was revolutionary and introduced many industry 'firsts' for the production car market. It was the first production car to use titanium connecting rods, six in total. The body and chassis was comprised of aluminum, weighing just over 460 pounds, much less than steel but with equal strength. The aluminum body housed many advanced technologies such as PGM-FI, Variable Valve Timing and Lift Electronic Control (VTEC), and a direct ignition system. The 3-liter DOHC V-6 engine was mounted mid-ship and matted to a five-speed manual gearbox. With 270 horsepower and 210 foot-pounds of torque, zero-to-sixty was accomplished in under six seconds.
Production was slow, but for good reason. Each vehicle was hand assembled by a team of technicians, with an average of about 20 examples being produced per day. During its introductory year only 1940 examples were produced. Sales continued to be strong through the 1990's and into the next millennium. By 2004, over 8000 examples were being produced each year.
Since its inception, minor aesthetic styling changes have occurred, most notably the pop-up halogen headlights have been replaced with fixed high-intensity-discharge (HID) beams. The rear wing has been changed since its introduction and various other parts of the body have been slightly modified to improve the drag coefficient. These small changes have increased the top speed from 167 to 175 mph.
Throughout the years, various mechanical components have been updated such as the suspension and the size of the tires. The larger-diameter wheels and tires did more for its appearance than it did for performance. In 1995 a Sequential Sportshift automatic transmission, inspired by Formula One racing, was offered as optional equipment. That was the same year that the NSX-T, the NSX but with a removable roof, was introduced. Other optional equipment offered through the years was a keyless entry system and a trunk-mounted CD changer, both introduced after the 2003 model year.
1997 was the big year for the NSX and one that many enthusiasts had been waiting for since its introduction. Although the NSX's 270 horsepower engine was powerful and the excellent weight-distribution of the vehicle offered superb handling, people wanted more. In 1997, Acura offered the NSX with a 3.2-liter V6 capable of producing 290 horsepower. Power was sent to the rear wheels courtesy of a six-speed manual gearbox.
Wild exterior colors having been offered such as the controversial love-or-hate Imola Orange Pearl with yellow interior. These colors are not only making a statement, they scream it. With limited numbers of these radical colors being chosen, it may make them more valuable in the future.
In 1999 Acura offered a special edition named the Alex Zanardi Edition, honoring the driver who captured the CART racing championship twice. Only 49 examples of these hard-top special edition models were created. Minor interior and exterior styling changes distinguish it from the normal NSX models, as does the Formula Red color scheme. The big news was its loss of nearly 150 pounds and improved suspension.
Though not offered in the US, racing inspired editions have been offered, mostly to the Japan market. In 1992 the NSX Type R had a weight reduction of over 100 kg's and a more aggressive suspension. To reduce the weight, all non-essential luxury items were removed such as air conditioning, electric windows, and stereo. The NSX Type S and Type S Zero were both offered in 1997. These were weight-reduction models with stiffer suspension but sporting the upgraded engine. The Type S Zero weighed less than the Type S by almost 40 kg. Both editions were sold exclusively in Japan with race track intentions. In 2002 the NSX-R was introduced. Once again, performance was increased by reducing weight and improving the suspension. Aerodynamics was improved by making subtle changes to the body and receiving a purpose-built rear spoiler. Later, an NSX-R GT version was released, with even more race-improving enhancements. These improvements allowed the vehicle to compete against much more powerful vehicles such as the Ferrari 360 Challenge Stradale.
From the beginning the NSX has been involved in racing. In its first year on the track it captured the Manufacturer's and Driver's Championship in the International Motor Sports Association (IMSA) GTP Lights series. This accomplishment was repeated in 1992 and 1993. In 1997 an NSX captured the SCCA World Challenge Championship.
The price tag and styling are borderline 'supercar' while the horsepower is a little under-rated when compared with some of the other great supercars such as Lamborghini and Ferrari. The entire package speaks for it self, with over 10 years in production and very little changes being implemented through the years. Though it does not produce the high horsepower numbers, it does have the highest per-litre output of any naturally aspirated V6 production road-going car in the world. Focusing on weight distribution, low weight, down-force, aerodynamics, suspension and technology rather than large engines has made this vehicle a technological and stylish marvel even to this day.
