Mazda RX-8: the rotary four-seater, its specs, faults and values

The Mazda RX-8 is a four-door, four-seat sports coupe with a 1.3-litre twin-rotor Wankel engine, built by Mazda at its Ujina plant in Hiroshima from 2003 to June 2012. Mazda made 192,094 of them by the end of March 2012, and the last one, built on 22 June 2012, was the last production car whose wheels were driven by a rotary engine.
In the UK the RX-8 went on sale in July 2003 at £19,995 with 192PS or £21,995 with 231PS, and was withdrawn in 2010 when its engine could not meet the Euro 5 emissions rules. A running 192PS car sold at auction for £3,240 in January 2026, and a late R3 costs up to about £8,000. At GOV.UK's rates in October 2026 road tax is £790 a year for a car registered from 23 March 2006 and £445 for an earlier one; real-world economy is about 20mpg, and a rebuilt engine costs about £3,200.
Mazda RX-8 history and development
The RX-8 replaced the RX-7, the twin-turbo rotary coupe whose final edition, the Spirit R, Mazda introduced in March 2002, and it was built around a new rotary engine, the RENESIS. It followed two rotary concept cars, the RX-01 of 1995 and the RX-EVOLV of 1999, according to Mazda's centenary page on the RX-8.
From the RX-EVOLV concept to production
Mazda's engineers spent two years in the early 1990s on a new intake and exhaust layout for the rotary engine before the work stalled and the rotary engine came close to being dropped, the 15th episode of Mazda's centenary history recalls. The lead engineer went back to the development records left by the engineers who had first put the rotary into production, and met Kenichi Yamamoto, who had led that work. The engine that came out of it has both the intake and the exhaust ports in the sides of the housings. That page expands RENESIS as "Rotary Engine for New-generation with Exhaust-port on the Side and Intake-port on the Side"; Mazda's launch release of January 2003 gives a shorter meaning, "RE (Rotary Engine) GENESIS".
Mazda showed the RX-8 beside the Atenza (the Mazda6) at the 35th Tokyo Motor Show in October 2001, as Mazda's company history for 2000 to 2004 records. The styling was by Ikuo Maeda, whose father Matasaburo Maeda had drawn the first RX-7, as Lewis Kingston noted in The Intercooler's December 2025 feature on the car.
Launch in 2003
RENESIS production began at Ujina on 29 January 2003, with about 150 employees at the ceremony, and Executive Vice President Hisakazu Imaki called the engine "a symbol of Mazda's revival", according to Mazda's release of that day. Production of the car started in February and Japanese sales in April 2003 (Mazda's company history), at prices from 2,400,000 to 2,750,000 yen. By the end of October 2003 Mazda had sold 13,000 in Japan, "well exceeding its original target", Mazda reported in November 2003.
UK sales began in July 2003 with two versions: the £19,995 car with 192PS and a five-speed gearbox, and the £21,995 car with 231PS, a six-speed gearbox and a 9,000rpm limit (The Intercooler; Autocar's road-test data gives the same £21,995). The 100,000th RX-8 left the line in September 2004 (Mazda's company history).
The 2008 facelift and R3
Mazda unveiled a revised RX-8 at the North American International Auto Show in Detroit in January 2008, alongside the Furai concept, according to Mazda's company history for 2005 to 2009. The UK version, the R3, went on sale in late August 2008 at £24,995, as a single model with no factory options, said Mazda UK's release of 14 July 2008.

The facelift brought new bumpers, headlamps, round LED rear lamps and 90mm exhaust pipes, and a body shell 5.4 per cent stiffer in torsion and 8.7 per cent stiffer in bending. The final drive went from 4.444 to 4.777:1, the oil capacity grew to 7.0 litres, the metering oil pump became electrically driven, and a variable red zone on the rev counter limited revs until the engine was warm, according to the same release. The R3 also had Bilstein dampers, a urethane-foam-filled front suspension cross member, 19-inch wheels, Recaro front seats and a Bose stereo.
Why was the RX-8 discontinued?
The RX-8 was withdrawn from Europe because its engine could not meet the Euro 5 emissions regulations, as PistonHeads reported on 15 April 2010. In Japan Mazda announced on 7 October 2011 that production would end in June 2012, with the Spirit R as the last special edition, according to Mazda's release of that day. The last rotary engine for a production car was built on 21 June 2012 and the last RX-8 on 22 June, The Drive recorded in 2022. Evo's report of June 2012 put it down to fuel consumption: the RENESIS was more efficient than earlier rotaries but could not match the power, torque and economy of turbocharged piston engines.
Design and engineering
The RX-8 is a front-mid-engined, rear-wheel-drive car with four doors and four full-size seats. Mazda's January 2003 release credits the layout to the rotary engine's "compact size, light weight and high performance", which it said had let it create "a totally new sports car concept".
Freestyle doors and four seats

The rear doors are hinged at the back and open only after the front doors, so each side has a pillarless opening; Mazda called the meeting point of the two doors a "virtual pillar" that protects the occupants in a side impact, as the body section of PistonHeads' 2013 buying guide explains. The monocoque is steel, with an aluminium bonnet and plastic bumpers.
Mazda claimed a torsional rigidity of 30,000Nm per degree, which The Intercooler says is double that of the FD RX-7 and on a par with a 997-generation Porsche 911.
Interior and dimensions
The RX-8 is 4,430mm long on a 2,700mm wheelbase and the facelifted R3 4,470mm long, with a 290-litre boot behind a conventional boot lid, Parkers' specification pages show. Inside, the driver sits low behind an instrument cluster built around a central rev counter with its zero at six o'clock, and a stubby gear lever (The Intercooler); rotary triangles are moulded below the grille, into the headrests and into the bonnet, PistonHeads noted in 2024.

Autocar's testers liked the equipment, the design and the quality of the interior and the "cosy rear chairs", but called the "knees-bent, arms-straight driving position" a major weakness. UK 231PS cars had xenon headlamps with washers and self-levelling, where the 192PS cars had halogen lamps, and an electric tilt-and-slide sunroof was one of the few options (PistonHeads' body section).
The RENESIS rotary engine

The RENESIS (type 13B-MSP, for multi side port) is a Wankel rotary engine: a water-cooled two-rotor unit of 654cc per rotor, 1,308cc in all, developed from the 13B of the RX-7. Instead of pistons, each triangular rotor turns inside an oval housing and carries out intake, compression, combustion and exhaust in turn, which Mazda credits with "compact size and light weight", "flat torque performance" and "less vibration and low noise" in its November 2003 release. The side exhaust ports and a sequential dynamic air intake gave it more power than earlier naturally aspirated rotaries, with better economy and lower emissions.
The engine has only three major moving parts, but the tips of the rotors must be lubricated, so an oil metering pump feeds oil into the combustion chambers and the engine burns it by design, as the powertrain section of PistonHeads' 2013 guide puts it. The six-port engine revs to 9,000rpm; the four-port 192PS engine is limited to 7,500rpm.
The RENESIS won International Engine of the Year 2003 with 44 of the 50 judges' votes, and also took the 2.5-litre to 3-litre class and "Best New Engine of 2003", Mazda announced on 4 June 2003. The awards are run by the British magazine Engine Technology International, and the engine won its capacity class again in 2004.
Chassis and weight distribution
The engine sits behind the front axle line, which gives the RX-8 a 50:50 front-to-rear weight split, with double-wishbone front suspension, a multi-link rear, a limited-slip differential and a carbon-fibre propshaft on manual cars. The brakes are ventilated discs of 323mm at the front and 302mm at the rear (PistonHeads' 2013 buying guide).
Mazda RX-8 specs and performance
UK RX-8s had the same 1,308cc engine in two tunes: 192PS with a five-speed gearbox, and 231PS with a six-speed gearbox, the version the R3 kept. The 192PS engine has more torque than the 231PS one (162lb ft against 156lb ft), and Mazda UK sold no automatic; an automatic RX-8 in Britain is an import (PistonHeads).

Sources: 0–62mph, top speeds and economy from Parkers' engine review; kerb weights, CO2 and insurance groups from Parkers' specification pages for the 192PS, 231PS and R3 cars; torque and rev limits from PistonHeads' 2013 buying guide and The Intercooler; the 231PS peak and launch price from Autocar; R3 torque, performance, gearing and price from Mazda UK's 2008 release. PistonHeads' guide gives lower kerb weights for early cars, 1,373kg (192PS) and 1,379kg (231PS).
Japanese cars were rated higher under Japan's JIS net standard: 210PS at 7,200rpm and 222Nm for the standard engine, and 250PS at 8,500rpm and 216Nm for the Type S, according to Mazda's November 2003 release. WardsAuto gave 232hp for the 2009 North American manual car.
How fast is a Mazda RX-8?
A 231PS RX-8 reaches 62mph in 6.4 seconds and 146mph. Mazda UK gave the R3 the same figures; Parkers lists 6.3 seconds and 147mph. Autocar's road test of the 228bhp car, recalled in its "Greatest road tests ever" series in August 2022, timed 0–60mph in 7.1 seconds, 0–100mph in 18.1 seconds, a standing quarter mile in 15.3 seconds at 93mph and a top speed of 142mph.
Fuel and oil consumption
Autocar averaged 22.5mpg in its test, and The Intercooler puts real-world economy for an R3 at around 20mpg against a claimed 24.6mpg. Parkers lists CO2 emissions of 267g/km for the 192PS car, 284g/km for the 231PS car and 299g/km for the R3. PistonHeads' 2013 buying guide gives Mazda's figure for oil use when new as about 250ml per 1,000 miles, and Mazda's advice to check the level at every second fill of the tank.
RX-8 special editions and variants
UK buyers had the R3 and five special editions, among them 350 Nemesis cars, 500 Kuros and 800 PZs; Japan had its own trims and the final Spirit R, of which Mazda planned 2,000.
UK models and special editions
The Evolve, on the 231PS car, came in Copper Red Mica or Phantom Blue Mica with dark silver 18-inch wheels and headlamp surrounds, a rotary crest on the front spoiler, polished side vents and chromed exhaust pipes (PistonHeads' 2013 buying guide). The Nemesis looked similar but was based on the 192PS car; The Intercooler records 350 sold in Britain, 200 of them red and the rest Stormy Blue.

The PZ, unveiled by Mazda UK in May 2006, was developed with Prodrive: Bilstein dampers, Eibach springs lowering the car by 15mm, OZ ten-spoke wheels with Prodrive badges, lower-drag mirrors and a rear spoiler, in Galaxy Grey or Brilliant Black. Only 800 were made, all for Britain, and it went on sale on 1 July 2006, as Autoblog reported on 8 May 2006. The Kuro (Japanese for black) was finished in Sparkling Black Mica; PistonHeads puts the run at 500.
The 40th Anniversary edition, reported in December 2007, marked 40 years since the Cosmo Sport of 1967, had Bilstein dampers, a foam-filled front cross member, ten-spoke 18-inch wheels, blue-light fog lamps and a choice of Metropolitan Grey Mica or Crystal White Pearlescent, according to PistonHeads' report of 5 December 2007. Rob Lindley, Mazda UK's managing director, said then that more than 2,800 RX-8s had been registered in Britain that year.
Japanese editions and the Spirit R
Japan had its own run of trims, among them the Sport Prestige Limited II of October 2005 at 3,150,000 yen with sand-beige leather and Alcantara seats, announced in Mazda's release of 18 October 2005.

The last edition was the Spirit R, on sale in Japan from 24 November 2011 and named after the final RX-7. Mazda's release of 7 October 2011 gave the manual car, based on the Type RS, Recaro bucket seats and bronze 19-inch wheels, and the automatic, based on the Type E, leather seats and 18-inch gunmetal wheels; both had red brake calipers, black headlamp bezels and curtain airbags, at 3,250,000 yen for the manual and 3,120,000 yen for the automatic. The April 2012 release adds that the manual's wheels were forged and that it had Bilstein dampers and aero parts.
Mazda planned 1,000 Spirit Rs and added another 1,000 in April 2012 because of demand; the manual took 66 per cent of orders, and the three colours sold in nearly equal numbers, Mazda said in its release of 26 April 2012. A SkiddMark report of October 2011 noted that the Spirit R arrived during Mazda's celebrations of the 20th anniversary of the 787B's Le Mans win, and that Johnny Herbert, who drove the 787B to that win in 1991, drove the 787B again at the Circuit de la Sarthe in June 2011 for the first time in 20 years. Mazda's chairman Takashi Yamanouchi said in the October 2011 release: "Although RX-8 production is ending, the rotary engine will always represent the spirit of Mazda and Mazda remains committed to its ongoing development."
RX-8 Hydrogen RE
The RX-8 Hydrogen RE has a dual-fuel rotary engine that runs on hydrogen or petrol at the flick of a switch. Mazda showed it at the 2003 Tokyo Motor Show, received permission for public road tests in October 2004, and on 15 February 2006 leased the first two cars to Idemitsu Kosan and Iwatani International, the first leases of a hydrogen rotary car in the world, Mazda announced in a release that day.

In 2006 two more went to Hiroshima's city and prefectural governments, and in 2008 cars began running in Norway with the national hydrogen project HyNor, where it was Mazda's first hydrogen rotary car driven on roads outside Japan (Mazda's company history for 2005 to 2009).
Mazda RX-8 in motorsport
The RX-8's best-known results came in American endurance racing, where SpeedSource won the GT class of the Rolex 24 at Daytona twice. In 2008 the No. 70 car of Sylvain Tremblay, David Haskell, Nick Ham and Raphael Matos started from pole, led 323 of the 664 laps and finished more than five laps ahead of the second-placed Porsche, Mazda's 22nd class win at the race, as Mazda's race report of 28 January 2008 records.

SpeedSource's No. 70 RX-8 won the class again in January 2010, driven by David Haskell, Sylvain Tremblay, Nick Ham and Jonathan Bomarito: 707 laps, eighth overall and four laps ahead of the GT runner-up, a Porsche 997, in the race results kept by Racing Sports Cars. It was Mazda's 23rd class win at Daytona, and RX-8s took the top three places in GT qualifying, Mazda's racing report of March 2010 records.
In Britain the Classic Sports Car Club ran the RX-8 Trophy for road-legal first-generation 231PS cars of 2002 to 2008, within its Tin Tops series; the club's RX-8 Trophy page says the class closed after seven seasons and the cars can still race in its other series.
How many Mazda RX-8s were made?
Mazda built 192,094 RX-8s from the start of sales in April 2003 to the end of March 2012, including cars for export, and production ran on until 22 June 2012 (Mazda's release of 26 April 2012).

Mazda sold more than 17,000 RX-8s in the UK by the time the R3 was dropped, PistonHeads' 2013 buying guide records. In December 2025 The Intercooler gave the DVLA's count as about 7,840 RX-8s on file, almost 70 per cent of them unlicensed, against about 40 per cent of the 6,000 Nissan 350Zs on file.
Is the Mazda RX-8 reliable? Common problems
The RX-8's reliability problem is apex-seal wear: the rotor tips wear against the housings, compression falls, the car stops starting when hot, and the cure is a rebuilt engine at about £3,200. The rotary is "long known for its ability to eat its own pressure-containing apex seals, and to trash its rotor housings", The Intercooler wrote in 2025.
Apex seals, compression and hot starting
Ask for a compression test by a rotary specialist or a Mazda dealer before buying; a worn engine shows up as poor starting when warm (PistonHeads). Poor hot starting can also come from the four coil packs (one per spark plug, to be replaced every 30,000 miles at about £80 each in 2013) or worn plugs and leads, and The Intercooler adds a tired starter motor to the list. Ryan Rotary Performance quoted £3,205 for a warranted rebuilt unit in The Intercooler's December 2025 feature.
Oil, flooding and catalytic converters
The engine burns oil by design, so the level must be checked often. In 2013 PistonHeads' buying guide said a seller should name Mazda's own Dexelia 5W-30 mineral oil when asked what the car runs on. The Intercooler adds that the engine dislikes short journeys and long idling from cold. Switching the engine off before it is warm can flood it, because the engine runs rich to warm itself and the catalytic converter; the unburnt fuel also overheats the catalyst. A Mazda catalytic converter cost about £1,400 in 2013, against about £200 for an aftermarket one. A ticking noise and lost power can mean a broken secondary shutter valve in the inlet manifold (PistonHeads' powertrain section).
Chassis, body and recalls
The suspension is hard-wearing; front anti-roll bar drop links are the usual worn part, shown by a clunk over bumps. The DVSA lists eight UK recalls for the RX-8, set out below. Early cars could rust on the sills where the front and rear door seals meet, and around the fuel filler and the high-level brake light; the oil cooler and air-conditioning radiators in the front bumper also rust, and Mazda fitted new front oil pipes and arch liners to cars whose pipes rusted from water coming through the wheelarch liners.
Mazda RX-8 recalls in the UK
The RX-8's UK recalls cover suspension, fuel leaks and airbags, according to the DVSA's vehicle recalls data, read 28 October 2026.
| Recall | Launched | Built | Defect | Vehicles |
|---|---|---|---|---|
| R/2004/029 | May 2004 | Jul–Aug 2003 | Manual gearbox dynamic damper heat insulator may crack or come off | 119 |
| R/2005/114 | Aug 2005 | Jul–Dec 2003 | Cracks in the front lower arm ball-joint socket; possible loss of steering | 4,621 |
| R/2005/115 | Aug 2005 | Jul 2003–Jul 2005 (two build ranges) | Long high-rev running while parked can melt parts near the exhaust and damage the fuel tank | 15,054 |
| R/2016/084 | Apr 2016 | Feb 2003–Feb 2008 | Driver's airbag inflator may rupture | 32,030 |
| R/2018/014 | Jan 2018 | Jul 2003–Feb 2008 | Fuel pump rings and discharge pipe may deteriorate from heat and leak fuel | 25,190 |
| R/2018/015 | Jan 2018 | Jul 2003–May 2004 | Front lower arm ball-joint casting may crack | 8,030 |
| R/2018/317 | Nov 2018 | Jul 2003–Jul 2010 | Takata passenger airbag inflator | 26,261 |
| R/2021/411 | Dec 2021 | Apr 2008–Jul 2010 | Fuel may leak from the fuel pump rings | 1,924 |
What to check when buying an RX-8
These checks come from the faults above, as PistonHeads' 2013 guide and The Intercooler describe them:
- A compression test by a rotary specialist or Mazda dealer, with a figure for each rotor face.
- A hot start: drive the car until warm, switch off, and restart it.
- Dates of the last coil packs, plugs and leads; coils are due every 30,000 miles.
- Proof of the recall work in the table above, on the DVSA's checker by registration.
- Sills, the fuel filler, the front oil pipes and arch liners, and the oil cooler in the bumper, for rust.
- The oil level on the dipstick, and which oil the seller uses.
- A clunk from the front over bumps, which points to worn anti-roll bar drop links.
The US engine warranty extension
In June 2008 Mazda North American Operations extended the warranty on the RENESIS engine core to eight years or 100,000 miles, for the 2009 car and retrospectively for 2004 to 2008 cars with past service issues, as WardsAuto reported on 11 June 2008.
What is a Mazda RX-8 worth today?
Most RX-8s in the UK sell for between about £2,000 and £8,000, with tidy R3s at the top. In January 2026 a 2008 192PS car with 35,173 miles, three owners and a history of new plugs and coils sold for £3,240 including premium against an estimate of £2,500 to £3,500, according to Anglia Car Auctions' results. In its December 2025 feature The Intercooler watched a 60,000-mile Nemesis sell online for £1,950 including fees, and put later R3s at up to £8,000.
A dealer asked £7,995 for a one-owner 2008 R3 with 56,000 miles and a full main-dealer history in February 2024, and PistonHeads' report of that month put an ultra-low-mileage standard 2004 car at £11,995. Every RX-8 is over 225g/km, so at GOV.UK's vehicle tax rates (read 28 October 2026) a car first registered on or after 23 March 2006 is in band M at £790 a year, and an earlier one pays the band K rate of £445. Insurance groups are 27 for the 192PS car, 30 for the 231PS and 31 for the R3 (Parkers).
Rivals and reception
The Intercooler compares a used RX-8 with the Nissan 350Z, Honda S2000, BMW Z4 and Audi TT, and the RX-8 is the only one of the five with four doors and four seats.
Rivals
The Intercooler notes that the RX-8's 290-litre boot is larger than the 350Z's. As a cheap used coupe it also puts the RX-8 against the Toyota GT86 and Subaru BRZ.
What reviewers said
Autocar found the "superbike soundtrack and mechanical refinement" made the hard work worthwhile, but criticised the "relaxed, loping chassis set-up", the body roll, the poor rigidity it blamed partly on the missing B-pillars, and a "knees-bent, arms-straight driving position". It rated the R3 "the choice pick, with better suspension and lower gearing". The Intercooler's reading of the period reviews is that most testers liked the steering, the controls and the handling, and some found the car too soft, with too much roll and too little feedback.
Awards
Besides International Engine of the Year, the RX-8 was named 2004 RJC Car of the Year in Japan, with the RENESIS as RJC Technology of the Year, and won the "Most Fun" special award in the 2003–2004 Japan Car of the Year (Mazda's November 2003 release). It was Wheels magazine's Car of the Year in Australia, announced in January 2004 (Mazda's company history).
Will there be a new RX-8? Mazda's rotary since 2012
Mazda has built no rotary-engined sports car since the RX-8, but it has shown three rotary concept cars and put a rotary engine back into production as a generator. The RX-Vision concept of the 2015 Tokyo Motor Show was a front-engined, rear-drive sports car with a planned SKYACTIV-R rotary, "a dream the company one day hopes to make into reality", according to Mazda's company history for 2015 to 2019.

The Iconic SP of October 2023 used a twin-rotor engine with two electric motors for about 365bhp, and the MX-30 R-EV, in production from 2023, uses a rotary engine as a generator to charge its battery, according to Mazda's company history for 2020 to 2024 and Auto Express's report of February 2026. In October 2025 Mazda showed the Vision X-Coupé, a four-door with a turbocharged two-rotor plug-in hybrid system of 503bhp in which the rotors drive the wheels, "as they did in the old RX-3, RX-7 and RX-8 coupés", Autocar reported. Moritz Oswald, Mazda's product planning supervisor in Europe, told Auto Express that the MX-5 is still Mazda's halo car, and added: "Could there be something next to it or above? Yes."
Questions
Does the Mazda RX-8 have suicide doors?
Yes. Mazda calls them freestyle doors: the rear doors are hinged at the back and open only after the front doors, leaving an opening with no pillar between the front and rear seats.
What oil does a Mazda RX-8 take?
In 2013 PistonHeads' buying guide said a seller should name Mazda's own Dexelia 5W-30 mineral oil when asked what the car runs on. The engine injects oil into its combustion chambers to lubricate the rotor tips, so the level needs checking about every second tank of fuel.
Was the Mazda RX-8 sold with an automatic gearbox in the UK?
No. Mazda UK sold only manuals: a five-speed with the 192PS engine and a six-speed with the 231PS engine, so an automatic RX-8 in Britain is an import. In Japan Mazda sold automatics up to the final Spirit R.
How much is road tax on a Mazda RX-8?
At GOV.UK's rates read on 28 October 2026, an RX-8 first registered on or after 23 March 2006 is in band M and pays £790 a year; an earlier car pays the band K rate of £445. Parkers lists CO2 of 267g/km for the 192PS car, 284g/km for the 231PS car and 299g/km for the R3.
Which Mazda RX-8 is the best to buy?
Autocar called the 2008 R3 "the choice pick, with better suspension and lower gearing", and PistonHeads called it "by far the best RX-8 we got here in the UK" in 2024. Mazda UK's 2008 release lists its changes: a body shell 5.4 per cent stiffer in torsion, Bilstein dampers, a lower final drive, 19-inch wheels and Recaro seats.
Can you fit a different engine to a Mazda RX-8?
Yes: The Intercooler lists conversion kits for the Honda K-series four-cylinder, and notes that the engine bay will take GM's 3.6-litre LFX V6 and the LS V8.
