Honda NSX

The Honda NSX (sold as the Acura NSX in North America and Hong Kong ) is a sports car that was originally produced between 1990 and 2005 by Japanese automaker Honda. It was equipped with a mid-engine. rear-wheel drive layout, powered by an all-aluminium V6 gasoline (petrol) engine featuring Honda’s Variable Valve Timing and Lift Electronic Control (VTEC ) system. A long-rumored second generation NSX debuted as a concept car in 2012, equipped with an all-wheel drive V6 hybrid powertrain, and is scheduled to enter into production by 2015.

Development [ edit ]

In 1984 Honda commissioned the Italian car designer Pininfarina to design the HP-X ( H onda P ininfarina X perimental), [ 1 ] which had a mid-mounted C20A 2.0L V6 configuration.

After Honda decided to pursue the project its management informed its engineers that the new car would have to be as fast as anything coming from Italy and Germany. [ 2 ] The HP-X concept car evolved into the NS-X ( N ew S portscar e X perimental) prototype. The NS-X prototype and eventual production car were designed by a team led by Chief Designer Ken Okuyama and Executive Chief Engineer Shigeru Uehara. who subsequently would be placed in charge of the S2000 project.

The original performance target for the NS-X was the Ferrari 328. which was revised to the 348 as the design neared completion. Honda intended the NS-X to meet or exceed the performance of the Ferrari, while offering targeted reliability and a lower price point. For this reason, the 2.0L V6 of the HP-X was abandoned and replaced with a more powerful 3.0L VTEC V6 engine.

The bodywork design had been specifically researched by Ken Okuyama and Uehara after studying the 360 degree visibility inside an F-16 fighter jet cockpit. [ 3 ] Thematically the F-16 came into play in the exterior design as well as establishing the conceptual goals of the NSX. In the F-16 and other high performance craft such as unlimited hydroplanes, single seat race cars etc. the cockpit is located far forward on the body and in front of the power plant. This cab-forward layout was chosen early in the NSX’s design to optimize visibility while the long tail design enhanced high speed directional stability. [ 4 ] The NS-X was designed to showcase several Honda automotive technologies, many derived from its F1 motor-sports program .

The NS-X was the first production car to feature an all-aluminium monocoque body, [ 5 ] incorporating a revolutionary extruded aluminium alloy frame, and suspension. The use of aluminium in the body alone saved nearly 200kg in weight over the steel equivalent while the aluminium suspension saved an additional 20kg; a suspension compliance pivot helped maintain wheel alignment changes at a near zero value. [ 6 ] Other notable features included an independent, 4-channel anti-lock brake system; titanium connecting rods in the engine to permit reliable high-rpm operation; an electric power steering system; [ 7 ] Honda’s proprietary VTEC variable valve timing system (a first in the US) and, in 1995, the first electronic throttle control fitted to a Honda.

Honda spent a great deal of time and money developing the NS-X. With a robust motorsports apparatus, Honda had significant development resources at its disposal and made extensive use of them. Respected Japanese Formula One driver Satoru Nakajima. for example, was involved with Honda in the NS-X’s early on track development at Suzuka race circuit, where he performed many endurance distance duties related to chassis tuning.

Brazilian Formula One World Champion Ayrton Senna. for whom Honda had powered all three of his world championship-winning Formula One race cars before his death in 1994, was considered Honda’s main innovator in convincing the company to stiffen the NSX chassis further after initially testing the car at Honda’s Suzuka GP circuit in Japan. Senna further helped refine the original NSX’s suspension tuning and handling spending a whole day test driving prototypes and reporting his findings to Honda engineers after each of the day’s five testing sessions. [ 8 ] Senna also tested the NSX at the Nurburgring and other tracks. [ 9 ] The suspension development program was far-ranging and took place at the Tochigi Proving Grounds, the Suzuka circuit, the 179-turn Nurburgring Course in Germany, HPCC, and Hondas newest test track in Takasu, Hokkaido. [ 10 ] Honda automobile dealer Bobby Rahal (two-time CART PPG Cup and 1986 Indianapolis 500 champion) also participated in the car’s development. [ 11 ] Senna was given two cars by Honda. The newer one, a black 1993 model, license plate BSS-8888 (the letters meaning Beco – a childhood nickname – Senna Silva and the number 8 is a reference to his first F1 championship in 1988) is still in his family’s possession.

The production car made its first public appearances as the NS-X at the Chicago Auto Show in February 1989, and at the Tokyo Motor Show in October 1989 to positive reviews. Sports car enthusiasts focused their attention on its low height, body lines, and pronounced forward cockpit. Honda revised the vehicle’s name from NS-X to NSX before final production and sale.

The Honda NSX went on sale in Japan in 1990 at Honda Verno dealership sales channels, supplanting the Honda Prelude as the flagship model. The NSX was sold under Honda’s flagship Acura luxury brand starting in 1991 in North America and Hong Kong.

Manufacture and release [ edit ]

Upon its release in 1990, the NSX design concept measured 1,170mm (46in) in height, (141.3mm (5.56in) taller than the Ford GT40 ) and showcased Honda’s technology. The Japanese car maker’s race track innovations and competitive history were further exemplified on the road by the NSX’s ultra-rigid, ultra-light all aluminium monocoque chassis and front and rear double wishbone suspension, with forged control arms connected to forged alloy wheels.

The car additionally boasted the world’s first production car engine with titanium connecting rods, forged pistons, and ultra high-revving capabilities — the redline was at a lofty 8,000 rpm – all traits usually associated with track and race engineered motor cars. The NSX exterior had a dedicated 23-step paint process, including an aircraft type chromate coating designed for chemically protecting the aluminium bodywork and a waterborne paint for the base coat to achieve a clearer, more vivid top color and a smoother surface finish.

The car’s strong chassis rigidity and cornering/handling capabilities were the results of Ayrton Senna ‘s direct input with NSX’s chief engineers while testing the NSX prototype car at Honda’s Suzuka Circuit during its final development stages. [ 11 ] The NSX was initially assembled at the purpose-built Takanezawa RD Plant in Tochigi from 1989 to early 2004, when it was moved to Suzuka Plant for the remainder of its production life. The cars were assembled by approximately 200 of Honda’s highest-skilled and most experienced personnel, a team of hand-picked staff with a minimum of ten years assembly experience employed from various other Honda facilities to run the NSX operation. [ 2 ] After studying their main competitors such as Ferrari, Lamborghini and Porsche, Honda engineers designed the NSX in search of the perfect balance between usable power and reliability and thus produced a powerful naturally aspirated VTEC engine suitable for the extreme demands of both road and track.

One of the first magazine articles to offer NSX test data showed the lightweight 3.0L 270bhp (200kW) NSX producing a best 0-60 mp/h time of 5.03 seconds and 13.47 seconds for the quarter mile. [ 12 ] Also on a Ferrari 348 to NSX comparison, a 0-60mph time of 5.2 seconds was recorded for the 1991 NSX. [ 13 ]

Wheels magazine Australia awarded the Honda NSX the 1991 Car of the Year award, and the Acura-badged car was Automobile Magazine ‘ s Automobile of the Year that same year. Motor Trend proclaimed this Honda/Acura was good. No, it was better than that–it was great.

Ferrari. Porsche. and Jaguar had been put on notice. The all-aluminum NSX — partially developed at the Nuerburgring — was better in every way. [ 14 ]

Today the NSX is still considered by owners of the model as one of the most reliable exotic cars ever manufactured, with many examples exceeding 200,000 miles (320,000km) without serious notable reliability issues or having suffered manufacturer recalls. [ 15 ] Despite the original NSX ceasing production in 2005, the model still has a strong base of fans and supporters worldwide with owners clubs flourishing in Asia, USA, Canada and across Europe. [ citation needed ] International motoring authors like Andrew Frankel (AutoCar Motor) Russell Bulgin (Car) Mark Hales (Fast Lane) Gianni Marin (Gente Motore) and Bernd Ostmann (AutoMotor Und Sport) have not only lent their name to the NSX in print but publicly praised the technology and innovation of Honda’s NSX and in the BBC book NSX – Hondas Super Sports Car (ISBN 0 9517751 0 3 ) describe the vehicle as worthy of the title supercar.

Post-1997 3.2L North American Acura examples are known to achieve a 13.3 second quarter-mile time [ 16 ] (1997-2005 model year NSX-T; the 149lb (68kg) lighter Zanardi Edition NSX is closer to 13.2 seconds [ 17 ] ), 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. [ 18 ] 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.

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. However, electric windows and fore/aft electric seat adjusters were retained.

The stock forged alloy wheels were replaced with lighter forged aluminium wheels produced by Enkei. which reduced the car’s unsprung weight. The stock leather shift knob was replaced with a sculpted titanium piece. Overall, Honda managed to remove approximately 120kg (265lb) of weight, giving the NSX-R a final weight of 1,230kg (2,712lb).

Tuning 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. To reduce the tendency to oversteer, Honda fitted softer rear tires on the NSX. 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 effect of decreasing the oversteer tendency of the car.

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 3.0kg/mm—R 4.0kg/mm for the NSX versus F 8.0kg/mm—R 5.7kg/mm for the NSX-R).

Honda also increased the final drive ratio 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 power band at higher RPM. This change improved acceleration at the expense of top speed, and a higher (percentage) locking limited-slip differential was installed. Also, the NSX-R 3.0 liter DOHC VTEC V-6 engine had a blueprinted and balanced crankshaft assembly which is exactly the same labour-intensive high precision process done for Honda racing car engines built by highly qualified engine technicians.

The lightest of all NSX variants at 1,230kg (2,712lb), 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 and 17 rear wheels) were available for a hefty premium. Production ended in September 1995.

Beginning in 1995, the NSX-T with a removable targa top was introduced in Japan as a special order option and in North America in March 1995. [ 19 ] The NSX-T replaced the standard coupe entirely as the only version available post 1994 and all NSXs thereafter were in targa form with the notable exceptions of the Zanardi Special Edition NSX in 1999 and a handful of special order post-1997/pre-2002 3.2 litre coupes. The removable roof resulted in decreased chassis rigidity and Honda added about 100 pounds (45kg) of structural reinforcements to compensate, including significantly thicker frame sidesill rocker panels (the body component which contributes most to the chassis’s rigidity [ 20 ] ), bulkheads, roof pillars and the addition of new front/rear bulkhead and floorpan crossmembers. [ 21 ] The targa models, produced for the rest of the NSX’s production run thru 2005, sacrificed weight and some of the original coupe’s chassis rigidity in return for an open cockpit driving experience.

In addition to this major change, all subsequent NSX-Ts (1995-2001) had smaller-diameter front sway bars, slightly stiffer front springs, softer rear springs and firmer shock-dampers [ 22 ] to improve ride comfort and tire wear while reducing the tendency towards oversteer common in mid-engined vehicles. All roofs post 1995 were now body-coloured instead of black, although in Japan, the two-tone black roof/body colour was still available as an optional feature.

A lighter version of the variable ratio electric assisted power steering rack, previously found exclusively in the automatic transmission equipped NSXs, became standard on all models. Starting in 1995 the 5-speed transmission’s second gear ratio was lowered by 4.2% to improve driveability and provide better response and automatic transmissions received an optional Formula One-inspired Sport Shift with a unique steering column mounted electronic shifter. [ 23 ] Manual transmission cars received an improved Torque Reactive limited-slip differential – when combined with a new Throttle-By-Wire system, increased corner exit speeds by 10%. Other innovations beginning in 1995 included a new and lighter exhaust and muffler configuration for greater efficiency and lower emissions, [ 23 ] an OBD-II onboard diagnostic system, improvements in the Traction Control System (TCS) and newly developed fuel injectors. [ 24 ]

1997 performance-enhancing changes (Worldwide) [ edit ]

In 1997, the biggest changes to the performance of the current generation NSX were introduced worldwide. For 1997, engine displacement increased from 3.0L to 3.2L [ 25 ] using a thinner fiber-reinforced metal (FRM) cylinder liner. The exhaust manifold was reconfigured and made of stainless steel header pipes rather than a cast-iron manifold for improved performance and lighter weight.

The increased flow from this new configuration was a key contributor to the 20 additional horsepower drawn from the new engine. [ 26 ] This revised 3.2L C32B engine gave it slightly more rated power: from 274PS (202kW; 270hp) to 294PS (216kW; 290hp) while torque increased from 285N·m (210lb·ft) to 305N·m (225lb·ft) (manual transmission only). The net result increased the horsepower to weight ratio of the NSX by 7%. [ 27 ] The 4-speed automatic model retained its 3.0L engine and 252hp power output.

Another big change was the adoption of a 6-speed manual transmission with closer gear ratios and the addition of 3rd to 4th gear dual cone synchronizers. To handle the new engines added torque and power the small diameter twin-disc clutch system of the 5-speed was replaced by a dual-mass low-inertia single disc clutch system.

To offset the weight increase of the new 6-speed transmission and larger brake rotors, which were upped from 11.1in (280mm) to 11.732 inches (298mm), key body parts were made with a new aluminum alloy that was up to 50% stronger allowing thinner lighter material to be used in the doors, fenders, and front and rear deck lids without any sacrifice of strength. [ 28 ] Using this hi-strength alloy the net curb weight increase, despite adding many improvements, was only 22lbs. Other notable changes included a keyless entry system and vehicle immobilizer system.

The combination of slightly increased power and torque and a 6-speed gearbox, with ratios optimized to improve straight-line acceleration, produced better performance numbers over previous models than the modest increases would suggest. Motor Trend [ 29 ] and Road and Track (Feb 97) tests of 3.2L 6-speed equipped NSX-T (Targa) roofed cars produced 0-60mph times of 4.8 and 5.0 seconds and quarter mile times of 13.3s and 13.5s respectively. [ 30 ] 0-60mph times dropped to as low as 4.5 seconds using a 3.2L hard top coupe model as recorded by Car and Driver in their August 1998 0-150-0 issue.

That NSX proved to be the fastest ever tested in North America. When Car and Driver tested the 1999 Zanardi special edition coupe a year later it produced a 4.8s 0-60 and a 13.2s 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 4.7s and a 13.1s quarter mile.

NSX-S, S-Zero (JDM) [ edit ]

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 1,320kg (2,910lb) and 1,280kg (2,820lb) respectively. Both had a stiffer suspension than the normal NSX. S-Zero was developed in a track day car that could be driven so that it had a 3.2L engine, rather than just 3.0L.

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.

Alex Zanardi Edition NSX [ edit ]

Produced exclusively for the United States, the Alex Zanardi Edition NSX was introduced in 1999 to commemorate Alex Zanardi ‘s two back-to-back CART Champ Car championship wins for Honda / Acura in 1997 and 1998. Only fifty-one examples were built, and they were available only in New Formula Red to reflect the color of the Champ Car Zanardi drove for Chip Ganassi Racing .

The Zanardi Edition was similar to the Japanese market NSX Type S. Visible differences between the Zanardi Edition and the Type S were the Zanardi’s left-hand drive, black leather and suede seats with red stitching, airbag-equipped Acura steering wheel, and a brushed-aluminium plaque with an engraved Acura logo, Zanardi’s signature, and a serial number on the rear bulkhead. Total vehicle weight is reduced 149 pounds (68kg) compared to the NSX-T, through the use of a fixed hard-top roof, lighter rear spoiler, single pane rear glass, lightweight BBS alloy wheels, a lighter battery, and a manual rack-and-pinion steering system in place of the electric power steering.

Zanardi Number 0 was a press car that also appeared in auto shows across the country. In a handling test in Road Track s June 1999 issue, this Zanardi NSX placed second against the Dodge Viper GTS-R, Lotus Esprit. Porsche 911 Carrera 4, Ferrari F355 Spider, and Chevrolet Corvette C5 Coupe. The car was also featured in Car and Driver s July 1999 issue before being sold to a private individual. [ citation needed ]

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. [ citation needed ]

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

NSX Refresh (worldwide) [ edit ]

NSX after facelift

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. Front spring rates were increased from 3.2kg/m to 3.5kg/m, rear spring rates were increased from 3.8kg/m to 4.0kg/m and the diameter of the rear stabilizer bar increased from 17.5mm to 19.1mm with a 2.3mm wall thickness.

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.

NSX-R Refresh (JDM) [ edit ]

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. 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 100kg (220lb) to 1,270kg (2,800lb).

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 290bhp (220kW), which is identical to the stock NSX. The automotive press, however, has long speculated that the true output of the engine is higher.

Creating the impression of increased power the accelerator was remapped, becoming much more sensitive to movement, particularly at the beginning of the pedal’s new shorter stroke. [ 31 ] This, coupled with the harsh suspension, makes it very hard for the driver to drive smoothly at low speeds on streets with even slight bumps. The lack of power steering has also been noted by drivers as making the car tiring and hard to steer at low speed. [ 32 ]

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 Nurburgring road course in 7:56, a time equal to a Ferrari F360 Challenge Stradale. [ 33 ] The NSX-R accomplished this feat despite being out-powered by the Ferrari by over 100bhp (75kW).

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 functional snorkel 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.

NSX-S Refresh (JDM) [ edit ]

The second iteration NSX-S, sold exclusively in Japan like other sports NSXs, continues with the face-lifted NSX keeping the weight at 1,320kg (2,910lb).

The end of the NSX [ edit ]

Production of European models ended in September 2005, followed North American models in December 2005. As of the end of June 2005, the NSX achieved total worldwide sales of more than 18,000* units during the 15 years it was in production. [ 34 ]

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 and performance on par with the most modern high performance sports cars.

On its launch in 1990, the NSX had been a technological marvel, but by 2005 Ferrari had gone from the 348. which was the original benchmark for the NSX development team, to the F355. 360 and to the F430. In July 2005, Honda officially announced that it would cease manufacturing NSX after 15 years, and transfer its research and development efforts to the search for its successor.

The last NSX sale in the US took place in Spokane, Washington in the summer of 2006—originally intended for Honda’s museum.

Honda NSX Mugen RR concept [ edit ]

At the 2008 Tokyo Auto Salon. Honda unveiled a Honda NSX Mugen RR concept vehicle, which included 255/35R18 and 335/30R18 tires, widened front, multi-grooved rear diffuser, adjustable rear wing. [ 35 ] The Mugen NSX RR concept is powered by a modified 3.2L V6, and has had its mounting changed from transverse to longitudinal. The change in mounting position, done in-house at Mugen’s facility via custom mounts, subframe, transmission, and other key components, allows for better power transfer to the rear wheels, and for a better exhaust flow that goes straight out the rear of the car rather than under the engine and then out.
