Post-1997 3.2 L North American Acura examples are known to achieve a 13.3 second quarter-mile time (1997-2005 model year NSX-T; the 149 lb (67.6 kg) lighter Zanardi Edition NSX is closer to 13.2 seconds ), while the Japanese NSX-R (2002+) is known to perform a 12.8 second quarter-mile time as measured by Japan's "Best Motoring" TV show. This ability is a result of the high redline, flat torque curve, short gear ratios, light weight and mid-engine layout, along with the slight power increase.

First generation NSX-R (JDM)

While the NSX always was intended to be a world-class sports car, engineers had made some compromises in order to strike a suitable balance between raw performance and daily driveability. For those NSX customers seeking a no-compromise racing experience, Honda decided in 1992 to produce a version of the NSX specifically modified for superior on-track performance at the expense of customary creature comforts. Thus, the NSX Type R (or NSX-R) was born. Honda chose to use its moniker of Type-R

 to designate the NSX-R's race-oriented design.

Honda engineers started with a base NSX coupe and embarked on an aggressive program of weight reduction. Sound deadening, the audio system, spare tire, air conditioning system and traction control along with some of the electrical equipment was removed. The power leather seats were replaced with lightweight carbon fiber racing seats manufactured for Honda by Recaro

. The stock leather shift knob was replaced with a sculpted titanium piece. Overall, Honda managed to remove approximately 120 kg (265 lb) of weight, giving the NSX-R a final weight of 1230 kg (2,712 lb).

Tuning to the suspension, it was well known by 1992 that the NSX, due to its mid-engine layout and rear-end link travel, was susceptible to a sudden oversteer condition during certain cornering maneuvers. While this condition rarely occurred during spirited street driving, it was much more prevalent on race tracks where speeds were much higher. To address the problem and improve the NSX-R's cornering stability at the limit; Honda added one aluminum bracket under the front battery tray and added one aluminum bracket in front of the front radiator to add more chassis rigidity then replaced the entire suspension with stiffer front sway bar, stiffer suspension bushings, stiffer coil springs and stiffer dampers.

The stock NSX has a rear bias in its spring rates, where the rear springs are stiffer than the front. On hard deceleration upon corner entry, the softer front springs allow weight transfer to the front wheels, increasing front grip and thus improving steering response. However, the weight transfer also takes weight off of the rear wheels, causing them to lose grip. The net result is a tendency toward oversteer, as the rear wheels are more likely to break traction and cause a fishtail or spin. For the NSX-R, Honda reversed the spring bias, placing stiffer springs on the front suspension along with stiffer front sway bar. This had the effect of preventing weight transfer to the front suspension under hard braking. This way, the rear tires would remain firmly set when entering the corner. Of course, by keeping weight off of the front wheels, front grip was reduced and the change therefore had the negative effect of increasing the understeer

 tendency of the car. This change required better driver skill to manage. Overall, the NSX-R uses much stiffer front sway bar along with stiffer springs than the stock NSX (21.0mm xt2.6mm front sway bar :F 3.0 kg/mm—R 4.0 kg/mm for the NSX versus F 8.0 kg/mm—R 5.7 kg/mm for the NSX-R).

Honda also changed the final drive ratio by lowering to a 4.235:1 ring and pinion gear in place of the 4.06:1 stock unit which moved the NSX-R's gear shifting points higher into the powerband at higher rpm's. This change greatly improved acceleration at the expense of top speed and higher (percentage) locking limited-slip differential was installed. Also, the NSX-R 3.0 liter DOHC VTEC V-6 engine has a blueprinted and balanced crankshaft assembly which is exactly the same labor-intensive high precision process done for Honda racing car engines built by highly qualified engine technicians.

The lightest of all NSX variants at 1230 kg (2,712 lb), the First-Gen NSX-R is capable of blistering track performance, though the ride can be jarring and noisy due to the stiff suspension bushings, stiff spring rates and lack of sound insulation.

Beginning in late November 1992, Honda produced a limited number of 483 NSX-R variants exclusively for the Japanese domestic market (JDM). Factory optional items as Air conditioning, BOSE stereo system, Carbon fiber trim center console with Carbon fiber door trim and starting in 1994 Championship White painted larger wheels (16"front wheels/17"rear wheels) were available for a hefty premium. Production ended in September 1995.

NSX-T

In 1995 the NSX-T with a targa top

 roof was released in Japan as a special order option. In North America, the NSX-T replaced the standard coupe entirely as the only trim available, with the notable exceptions of the Zanardi Edition NSX in 1999 and a handful of special ordered post-1997/pre-2002 3.2 liter coupes. The removable roof reduced the chassis rigidity of the NSX and added about 100 pounds (45 kg) of structural reinforcements. In addition to this major change, the suspensions have also been softened to improve ride, comfort, and tire wear, at the ultimate expense of handling. The suspension redesign was also intended to reduce the sudden-oversteer problems that plagued most mid-engined vehicles. All roofs were now body-colored instead of black, although in Japan the two-tone black roof/body color was still available as an optional feature. Finally available in the manual transmission version NSX was electric power steering, previously found in the automatic version exclusively.

1997 performance-enhancing changes (Worldwide)

1997 brought the biggest changes to the performance of the current generation NSX for the Japanese domestic versions and abroad. For 1997 engine displacement increased from 3.0 L to 3.2 L using a thinner fiber-reinforced metal (FRM) cylinder liner. This revised 3.2 L C32B engine gave it slightly more rated power: from 274 PS to 294 PS while torque increased from 285 newton metre to 305 newton metre (manual transmission only). The 4-speed automatic model still used the 3.0 L engine and power output. Another big change was the adoption of the 6-speed manual transmission. The combination of slightly increased power and torque, 6-speed manual gearbox, and optimized gear ratio produced improved straight-line acceleration. The new NSX rang up better numbers than the power and torque improvements may suggest over previous model NSXs. 0-60 mph times dropped from 5.2 to as low as 4.5 as recorded by Car and Driver in their August 1998 0-150-0 issue using a 3.2 hard top coupe. That NSX proved to be the fastest tested in North America. When Car and Driver tested the Zanardi special edition NSX a year it managed a 4.8 0-60 and a 13.2 quarter mile. Although magazine tests for the 02+ models were rare Honda apparently kept improving the engine as Sports and Exotic Car magazine did a farewell article on a 2005 NSX-T and recorded a 0-60 time of 4.7 and a 13.1 quarter mile on the heavier targa model. Other notable changes include a brake rotor size increase from 11.1 in (281.9 mm) to 11.732 inches (298 mm) — which necessitated larger wheels and tires, a new aluminium alloy to further reduce weight and increase rigidity, and a transponder in the key.

NSX-S, S-Zero (JDM)

Along with the engine displacement increase in 1997, Japan exclusively received the NSX type S (NSX-S) and NSX type S Zero (NSX-S-Zero), weighing in at 1320 kg (2,910.1 lb) and 1280 kg (2,821.9 lb) respectively. Both had a stiffer suspension than the normal NSX.

Unlike the standard Type S, the S-Zero does not offer Air Conditioning, navigation, and stereo system as an option. The suspension is stiffer than the standard Type S by using the NA1 Type R (1992 to 1995) suspension but retaining the Type S's larger rear sway bar. Changes were also made to the interior's manual transmission boot shifter, replacing the original material from leather to mesh.

Zanardi Number 1 belongs to Zanardi himself and was not given a North American VIN. The car is rumored to have been modified by Honda with hand-activated throttle, braking, and shifting mechanisms to accommodate Zanardi's loss of both legs resulting from his Lausitzring crash in 2001.

Zanardi numbers 2 through 50 were sold to the general public through dealers.

"Facelifted" NSX (worldwide)

The original NSX body design received only minor modifications from Honda in the new millennium when in 2002 the original pop-up headlamps were replaced with fixed xenon HID headlamp units (see photo from L.A. Auto Show 2003) along with slightly wider rear tires to complement a revised suspension.

The fixed roof NSX was dropped in 2002 (North America). The NSX was now made available in a number of exterior colors with either a matching or black interior to provide a number of possible color combinations. A 4-speed automatic transmission with manual-type shift option also became available.

Second generation NSX-R (JDM)

A second iteration of the NSX-R was released in 2002, again exclusively in Japan. As with the first NSX-R, weight reduction was the primary focus for performance enhancement. The chassis is based on the fixed-roof coupe, due to its lighter weight and more rigid construction. Carbon fiber was used to a large extent throughout the body components to reduce weight, including a larger, more aggressive rear spoiler
Spoiler (aeronautics)

By doing so, the spoiler creates a carefully controlled stall over the portion of the wing behind it, greatly...

, vented hood and deck lid. The vented hood was said to be the largest one-piece carbon-fiber hood in production cars. Additionally, the original NSX-R weight reduction techniques were repeated, including deletion of the audio system, sound insulation and air conditioning. Furthermore, the power steering was removed. A single-pane rear divider was again used, as were carbon-kevlar racing seats manufactured for Honda by Recaro. Finally, larger yet lighter wheels resulted in a total weight reduction of almost 100 kg (220 lb) to 1270 kg (2,799.9 lb).

The 3.2L DOHC V6 engine received special attention as well. Each NSX-R engine was hand assembled by a skilled technician using techniques normally reserved for racing programs. Components of the rotating assembly (pistons, rods and crank) were precision weighed and matched so that all components fell within a very small tolerance of weight differential. Then, the entire rotating assembly was balanced to a level of accuracy ten times that of a typical NSX engine. This balancing and blueprinting process significantly reduced parasitic loss of power due to inertial imbalance, resulting in a more powerful, free-revving powerplant with excellent throttle response. Officially, Honda maintains that the power output of the Second-Gen NSX-R engine is 290 bhp, which is identical to the stock NSX. The automotive press, however, has long speculated that the true output of the engine is higher.

The result of Honda's second NSX-R effort was a vehicle that could challenge the latest sports car models on the track, despite having a base design that was more than 15 years old. For example, noted Japanese race and test driver Motoharu Kurosawa

 piloted a 2003 NSX-R around the legendary Nurburgring road course in 7:56, a time equal to a Ferrari F360 Challenge Stradale. The NSX-R accomplished this feat despite being out-powered by the Ferrari by over 100 bhp.

NSX-R GT (JDM)

After the release of the Second-Gen NSX-R, Honda developed a more agile, more responsive, and quicker limited edition NSX-R called the NSX-R GT. The NSX-R GT was created by Honda solely to comply with the Super GT production-based race car homologation requirements. As JGTC rules required at least five production cars for any race car version to compete, the NSX-R GT was limited to a production run of only five cars.

The differences between the Second-Gen NSX-R and the NSX-R GT are not fully known. One clear difference is the addition of a non-functional snorkel
Vehicle snorkel
A vehicle snorkel is the land-based equivalent of the submarine snorkel which allowed submarines to use diesel engines while submerged. Snorkels, when used by vehicles with air-breathing internal combustion engines, allow limited deep fording capability for river crossing or amphibious landing...

 attached to the roof of the car. In the JGTC NSX race cars however, this snorkel is fully functional, feeding outside air to an individual throttle body intake plenum. The NSX-R GT also has a lowered suspension and widened body. More aggressive aerodynamic components such as an extended front spoiler lip and large rear diffuser are used as well. It also is speculated that the NSX-R GT incorporates more weight savings over the NSX-R. Honda never advertised what, if any, changes were made to the 3.2L DOHC V6 for the NSX-R GT.

Second generation NSX-S (JDM)

The second iteration NSX-S, sold exclusively in Japan like other sports NSXs, continues with the face-lifted NSX keeping the weight at 1320 kg (2,910.1 lb).

The end of the NSX

By 2005, NSX unit sales amounted to a few hundred vehicles per year worldwide. Honda deemed continuation of the NSX was not economically viable, considering the very high cost of manufacturing the NSX along with the company's growing interest in producing a new model with a V10 engine

The next generation

In April 2011, Automotive News reported that Honda is developing a new sports car to be a successor to the NSX. It reports that Honda CEO Ito said the car would be exhilarating to drive but also environmentally friendly. It is expected the vehicle will incorporate an electric drivetrain to give the gasoline engine a boost. Back in late 2010, Motor Trend reported that Honda was looking into a mid-engine hybrid sports car, to be an NSX successor.

The NSX was marketed as the first "Everyday Supercar" thanks in part to its ease of use, quality and reliability. Murray himself remained an NSX owner for 7 years.

Using a stroker crankshaft from Toda Racing, the naturally aspirated engine displaced 3.5 liters and produced nearly 500 bhp.
