The Honda NSX (Acura NSX in North America and Hong Kong) is a sports car produced by the Japanese automaker Honda. It has a mid-engine, rear-wheel drive layout, an all-aluminium body and chassis, a V6 gasoline engine (the C32B) that produces 216 kW (290 bhp) and 304 N·m (224 ft·lbf) of torque.
"NSX" is an acronym for "New Sportscar eXperimental" when it was presented (as NS-X) at the Chicago Auto Show in February 1989 and at the Tokyo Motor Show in October 1989. Internal Honda sources say the X initially stood for unknown in the codename of the car while it was in development.
[] Manufacture and release
Upon its release in 1990, the NSX was a design ahead of its time. The car was intended to showcase Honda's racing technology, exemplified by the NSX's titanium connecting rods. The car was designed with the input of Ayrton Senna and was assembled at its Tochigi plant by 200 hand-picked staff from various Honda factories. Each of them had at least ten years of experience in car assembly before they were chosen.
Despite the NSX's current age, it still has a strong base of fans and supporters. Honda and others describe the NSX as a supercar based on its styling, body type, drivetrain layout, and handling. Some people have disagreed, claiming that the Honda NSX is not powerful enough. Still, for a time, it sported the highest per-litre specific output of any road-going naturally aspirated V6 in the world and is exceptionally fast for the motor's relatively low power output versus comparable "supercars". The American (Acura) models are commonly known to achieve a 13.3 second quarter-mile time (1997+ model years), while the Japanese NSX-R (2002+) is known to perform a 12.8 second quarter-mile. The surprising performance is due mostly to a high 8,000 rpm redline, flat power curve, short gears, and mid-engine layout.
On July 20, 2005, mere days after the announcement of the closure of current NSX production, Honda CEO Takeo Fukui announced that a new NSX was under development and would sport a Formula 1-inspired V10 motor, with speculation that it might have the SH-AWD (Super Handling All Wheel Drive) system from the Acura RL. In addition, he stated it would be ready within three to four years.
[] Refinements and versions
Honda shocked the exotic car world when it introduced its NSX in 1990. Honda designers started with the basic exotic-car wedge (championed by the Ferrari Testarossa and 308), that would remain basically unchanged for its entire life. To back up the styling, the mechanical specifications were right out of a race car. The NSX featured a super-light all-aluminum chassis, body, and suspension, a first for a production car. The suspension was a double wishbone suspension, mounted at both ends on aluminum subframes. The standard race-inspired V6 engine was mounted midship and featured Variable Valve Timing and Lift Electronic Control (VTEC), six individual coils, and titanium connecting rods. This was the first application of VTEC in a vehicle offered outside of Japan.
Beginning in 1992 Honda produced a limited number of around 500 NSX-Rs for the Japanese domestic market. Major changes include a blueprinted engine producing 280 BHP in stock form, a short ratio gearbox, more aggressive suspension and an extensive weight reduction to 1230 kg from the normal NSX weight of 1350 kg. The NSX-R was very track oriented as it lacked sound deadening, audio, electric windows, and air conditioning in an effort to reduce weight. Yet these items were available for a hefty premium as optional items. Production ended in 1995.
In 1995 the NSX-T was released with a targa top roof. The removable roof hurt the chassis rigidity of the NSX and added about 100 pounds of weight. Nevertheless, the NSX-T was the only NSX available in the U.S. for 1995 - coupes were not available. All roofs were now body colored instead of black and several new colors were available. Finally available on the manual transmission version NSX was the electric power steering previously only available in the automatic version.
1997 brought the biggest changes to the performance of the current generation NSX. For 1997 engine displacement increased from 3.0 L to 3.2 L. This new 3.2 L C32B engine gave it slightly more rated power. This improved horsepower from 270 hp to 290 hp while torque increased from 210 to 224 ft·lbf (manual transmission only). Another big change was the change from a 5-speed transmission to the current 6-speed manual. On the dragstrip, the new NSX rang up better numbers than the horsepower and torque improvements may suggest over previous model NSXs. Other notable changes include a brake rotor size increase from 12 inches to 13 inches, a new aluminum alloy to reduce weight and increase rigidity, and a transponder in the key.
Along with the engine enlargement in 1997, Japan received the NSX type S and NSX type S Zero, weighing in at 1320 kg and 1280 kg, respectively, and both with stiffer suspension than the normal NSX.
The biggest exterior changes for the NSX came in 2002 when it received a facelift with fixed headlights and various other cosmetic refinements such as xenon HID headlamps (see photo from LA Autoshow 2003). The fixed roof NSX was dropped for the 2002 model year. The suspension was revised and the NSX received larger wheels and tires. In addition, the NSX was now available in a number of exterior colors with either a matching or black interior to provide a number of possible color combinations.
A second iteration of the type-R dubbed NSX-R was released in 2002, again exclusively in Japan. The NSX-R has a more aggressive rear spoiler and hood vent, along with various refinements to reduce weight to 1270 kg. Under the body, panels and air fences in the front, along with a small rear diffuser serve to produce balanced downforce. The subtle changes along with its renowned handling have kept NSX-R in contention on the track even against considerably higher-powered cars, such as the Ferrari 360 Challenge Stradale, whose Nordschleife lap time it tied.
A more agile, more responsive, and quicker limited edition NSX called the NSX-R GT was later released. This model was limited to a production run of 5 cars, at a cost of US$ 462,400. This NSX was created to help Honda comply with the Super GT production-based race car requirements. It's easily identifiable by the non-functional snorkel attached to the roof of the car (this is functional in the Super GT race cars), lower and widened body, and more aggressive aerodynamic components.
The Type-S continues with the face-lifted NSX keeping the weight at 1320 kg.
