Hydrogen RE

Mazda is focusing on the development of the RENESIS hydrogen rotary engine as one of the steppingstones toward the realization of a more earth-friendly and sustainable society while improving vehicles, maintaining people's interest in cars and benefiting the earth.This hydrogen engine takes advantage of the characteristics of Mazda's unique rotary engine and maintains a natural driving feeling unique to internal combustion engines. It also achieves excellent environmental performance with zero CO2 emissions.Further, the hydrogen engine ensures performance and reliability equal to that of a gasoline engine. Since the gasoline version requires only a few design changes to allow it to operate on hydrogen, hydrogen-fueled rotary engine vehicles can be realized at low cost. In addition, because the dual-fuel system allows the engine to run on both hydrogen and gasoline, it is highly convenient for long-distance journeys and trips to areas with no hydrogen fuel supply.
The RENESIS hydrogen rotary engine employs direct injection, with electronically-controlled hydrogen gas injectors. This system draws in air from a side port and injects hydrogen directly into the intake chamber with an electronically-controlled hydrogen gas injector installed on the top of the rotor housing. The technology illustrated below takes full advantage of the benefits of the rotary engine in achieving hydrogen combustion.

In the practical application of hydrogen internal combustion engines, avoidance of so-called backfiring (premature ignition) is a major issue. Backfiring is ignition caused by the fuel coming in contact with hot engine parts during the intake process. In reciprocal engines, the intake, compression, combustion and exhaust processes take place in the same location—within the cylinders. As a result, the ignition plugs and exhaust valves reach a high temperature due to the heat of combustion and the intake process becomes prone to backfiring.In contrast, the RE structure has no intake and exhaust valves, and the low-temperature intake chamber and high-temperature combustion chamber are separated. This allows good combustion and helps avoid backfiring.Further, the RE encourages thorough mixing of hydrogen and air since the flow of the air-fuel mixture is stronger and the duration of the intake process is longer than in reciprocal engines.
Aiming to achieve a high output in hydrogen fuel mode, a direct injection system is applied by installing an electronically-controlled hydrogen gas injector on the top of the rotor housing. Structurally, the RE has considerable freedom of injector layout, so it is well suited to direct injection.Further, a gas injector for premixing is installed on the intake pipe enabling the combined use of direct injection and premixing, depending on driving conditions. This produces optimal hydrogen combustion.When in the gasoline fuel mode, fuel is supplied from the same gasoline injector as in the standard gasoline engine.
Lean burn and exhaust gas recirculation (EGR) are adopted to reduce nitrogen oxide (NOx) emissions. NOx is primarily reduced by lean burn at low engine speeds, and by EGR and a three-way catalyst at high engine speeds. The three-way catalyst is the same as the system used with the standard gasoline engine.Optimal and appropriate use of lean burn and EGR satisfies both goals of high output and low emissions. The volume of NOx emissions is about 90 percent reduced from the 2005 reference level.
When the system runs out of hydrogen fuel, it automatically switches to gasoline fuel. For increased convenience, the driver can also manually shift the fuel from hydrogen to gasoline at the touch of a button.

Familia Series Part 2 (2nd to 4th generation models)


Advancing with the times





The Familia, which debuted as a genuine family car in 1963, underwent its first full redesign in 1967, when it was given a modern oval body shape. The rotary-engined Familia R100 was introduced in 1968, following the launch of the Cosmo Sports. With its distinctive round rear lights, the Familia Rotary featured a 491 cc x 2 10A rotary engine that developed 100 PS and had a top speed of 180 kilometers per hour. It also accelerated from standstill to 400 meters in as little as 16.4 seconds. This performance put it at the top of its class. Emitting a unique high-pitched exhaust note, the Familia Rotary Coupe recorded its maiden victory at the Grand Prix of Singapore in 1969, and performed impressively at circuits in Belgium, Germany, the UK and South Africa.




The first oil price shock struck in 1973. The period also saw a growing demand for exhaust emissions regulations and improved safety. Mazda's third generation Familia made its debut in this severe climate. The new Familia offered improved comfort and control and in 1976 adopted lean-burn technology and Mazda's original oxidizing catalyst. This version earned a strong reputation for its practical value.




The Familia Hatchback appears in the movie, 'The Yellow Handkerchief of Happiness'





The 4th generation Familia was launched in 1977 after the oil price shock had ended and the business climate was beginning to recover. At the time, two-box hatchbacks were predominant in Europe's compact car market. The Familia targeted the youth market, and its styling was based on four themes: new values, versatility, economy and high quality, and these themes were sustained in subsequent iterations.




A bright red 5-door hatchback Familia appeared in the movie , 'The Yellow Handkerchief of Happiness' driven by the character Kinya Hanada who was played by Tetsuya Takeda. The interest sparked by the movie was maintained with the subsequent, very popular 'Red XG' Familia.

Relted information



  • Mazda (1920 - 1979)

  • Mazda (1980 - 1989)
  • The celebrated Familia was designed to cater to family outings. It began life as a modern van and went on to transform the image of commercial vehicles. In 1960, Mazda was planning to make inroads into the compact passenger vehicle segment and was developing a sedan equipped with a 600cc ~ 800cc watercooled engine, with the aim of becoming a fullscale automaker. On another front, market surveys indicated that customer preferences were leaning toward a lightweight van with performance and comfort a class above mini commercial vehicles. The company took notice and the focus of the development plans shifted from sedans to lightweight vans. The result was the Familia Van that was launched in September 1963. It came equipped with a 782cc new aluminum alloy watercooled inline four cylinder engine. Commercialization of this all aluminum alloy engine was made possible by advanced diecasting, shell molding and machining technologies that only Mazda possessed at that time. The Familia Van gained a favorable reputation for its engine and its distinctive taut, linear design. By February 1964, just four months after its launch, the model had climbed to the top of its class with a 44 percent market share.

    Familia Sedan changes the course sedan history
    While production of the Familia Van was expanding, Mazda exhibited the Mazda 700 compact passenger car at the 1961 Tokyo Motor Show and the Mazda 1000 prototype model the year after. In response to this favorable reception, Mazda progressed towards development of a Familia Sedan that would break the mold of conventional minicars with a design to suit the sensibilities of modern motorists. The result was the Familia Sedan launched in October 1964. It soon gained a name for itself as a model that delivered a balanced blend of performance, style and comfort. In the first month of sales, it garnered a 23 percent market share. Mazda added a wagon, a twodoor sedan and a truck to the Familia series and in December 1964 recorded an annual production volume topping 10,000 units. The Familia had established itself as Mazda's prime model.

Mazda Rotary Engine

All Mazda Wankel "rotary" engines are essentially a single family — they all derive from the first Wankel experiments in the early 1960s. Over the years, displacement has been increased (somewhat), and turbocharging has been added to great effect.

In auto racing, the displacement of a Wankel engine is usually doubled for classing purposes. For Japanese tax purposes, the displacement of Wankel engines is defined as the equivalent of 1.5 times the nominal displacement. So the 1.3 L 13B engines count as just under 2.0 L for these purposes.

Wankel engines can be classified by their rotor size in terms of width (diameter) and depth (thickness). These metrics function similarly to the bore and stroke measurements of a piston engine. Nearly all Mazda production Wankel engines share a single rotor diameter: 105 mm (4.1 in) with a 15 mm (0.6 in) crankshaft offset. The only engine to diverge from this formula was the rare 13A, which used a 120 mm (4.7 in) diameter and 17.5 mm (0.7 in) offset.

This engine is starting to become popular with kit car builders, hot rodders and in light aircraft because of its light weight, compact size and tuning potential stemming from is inherent high power to weight ratio.

40A
Mazda's first prototype Wankel was the 40A, a single-rotor engine very much like the NSU KKM400. Although never produced in volume, the 40A was a valuable testbed for Mazda engineers, and quickly demonstrated two serious challenges to the feasibility of the design: "chatter marks" in the housing, and heavy oil consumption. The chatter marks, nicknamed "devil's fingernails", were caused by the tip-seal vibrating at its natural frequency. The oil consumption problem was addressed with heat-resistant rubber oil seals at the sides of the rotors. This early engine had a rotor diameter of 90 mm (3.5 in), an offset of 14 mm (0.6 in), and a depth of 59 mm (2.3 in).


[edit] L8A
The very first Mazda Cosmo prototype used a 798 cc L8A two-rotor Wankel. The engine and car were both shown at the 1963 Tokyo Motor Show. Hollow cast iron apex seals reduced vibration by changing their resonance frequency and thus eliminated chatter marks. It used dry-sump lubrication. Rotor diameter was up from the 40A to 98 mm (3.9 in), but depth dropped to 56 mm (2.2 in).

One-, three-, and four-rotor derivatives of the L8A were also created for experimentation.


[edit] 10A
The 10A series was Mazda's first production Wankel, appearing in 1965. It was a two-rotor design, with each displacing 491 cc for a total of 982 cc. These engine featured the mainstream rotor dimensions with a 60 mm (2.4 in) depth.

The rotor housing was made of sand-cast aluminum plated with chrome, while the aluminum sides were sprayed with molten carbon steel for strength. Cast iron was used for the rotors themselves, and their eccentric shafts were of expensive chrome-molybdenum steel. The addition of aluminum/carbon apex seals addressed the chatter mark problem.


[edit] 0810
The first 10A engine was the 0810, used in the Series I Cosmo from May, 1965 through July, 1968. These cars, and their revolutionary engine, were often called L10A models. Gross output was 110 hp (82 kW) at 7000 rpm and 130 Nm (96 ft·lbf) at 3500 rpm, but both numbers were probably optimistic.

The 10A featured twin side intake ports per rotor, each fed by a one of four carburetor barrels. Only one port per rotor was used under low loads for added fuel economy. A single peripheral exhaust port routed hot gas through the coolest parts of the housing, and engine coolant flowed axially rather than the radial flow used by NSU. A bit of oil was mixed with the intake charge for lubrication.

The 0810 was modified for the racing Cosmos used at Nürburgring. These engines had both side- and peripheral-located intake ports switched with a butterfly valve for low- and high-RPM use (respectively)

Applications:

1965–1968 Mazda Cosmo Series I/L10A

[edit] 0813
The improved 0813 engine appeared in July, 1968 in the Series II/L10B Cosmo. Its construction was very similar to the 0810, but the ports and carburetion were revised to produce 130 hp (96 kW) at 7000 rpm and 140 Nm (103 ft·lbf) at 5000 rpm. Again, these were Japanese net output figures.

Applications:

1968–1972 Mazda Cosmo Series II/L10B

[edit] 0820
The 10A was substantially revised for wide-scale production in the R100/Familia Rotary. Many changes were made in an effort to reduce production costs. These included the use of cast iron in the housing sides, less-expensive molded (instead of sand-cast) aluminum for the housings, and chrome-steel for the eccentric shafts. The port arrangement remained the same, but exhaust was no longer routed around the housing.

Japanese-spec gross output was 100 hp (75 kW) at 7000 rpm and 98 ft·lbf (133 Nm) at 3500 rpm. The use of less-expensive components raised the weight of the engine from 224 lb (102 kg) to 268 lb (122 kg).

Applications:

1968–1973 Mazda R100/Familia Rotary

[edit] 0866
The final member of the 10A family was the 1971 0866. This variant featured a cast-iron thermal reactor to reduce exhaust emissions and re-tuned exhaust ports. The die-cast rotor housing was now coated with a new process: The new Transplant Coating Process (TCP) featured sprayed-on steel which is then coated with chrome. Gross output was 105 hp (78 kW) at 7000 rpm and 135 Nm (99.5 ft·lbf) at 3500 rpm.

Applications:

1972–1974 Mazda RX-3 (Japan-spec)

[edit] 13A
The 13A was designed especially for front wheel drive applications. It had two 655 cc rotors for a total of 1310 cc. This was the only production Mazda Wankel with different rotor dimensions: Diameter was 120 mm (4.7 in) and offset was 17.5 mm (0.7 in), but depth remained the same as the 10A at 60 mm (2.4 in). Another major difference from the previous engines was the integrated water-cooled oil cooler.

The 13A was used only in the 1969–1972 R130 Luce, where it produced 126 hp (94 kW) and 126 ft·lbf (172 Nm). This was the end of the line for this engine design: The next Luce was rear wheel drive and Mazda never again made a front wheel drive rotary vehicle.

Applications:

1970–1972 Mazda R130

[edit] 12A
The 12A was a "bored-out" version of the 10A — the rotor diameter was the same, but the depth was increased by 10 mm (0.4 in) to 70 mm (2.8 in). Each of its two rotors displaced 573 cc for a total of 1146 cc. The 12A series was produced for 15 years, from May 1970 through 1985. In 1974, a 12A became the first engine built outside of western Europe or the U.S to finish the 24 hours of Le Mans.

In 1974, a new process was used to harden the rotor housing. The Sheet-metal Insert Process (SIP) used a sheet of steel much like a conventional piston engine cylinder liner with a chrome plated surface. The side housing coating was also changed to eliminate the troublesome sprayed metal. The new "REST" process created such a strong housing, the old carbon seals could be abandoned in favor of conventional cast iron.

Early 12A engines also feature a thermal reactor, similar to the 0866 10A, and some use an exhaust port insert to reduce exhaust noise. A lean-burn version was introduced in 1979 (in Japan) and 1980 (in America) which substituted a more-conventional catalytic converter for this "afterburner". A major modification of the 12A architecture was the 6PI which featured variable induction ports.

Applications:

1970–1972 Mazda R100
1970–1974 Mazda RX-2, 130 hp (97 kW) and 115 ft·lbf (156 Nm)
1972–1974 Mazda RX-3 (Japan), 110 hp (82 kW) and 100 ft·lbf (135 Nm)
1972–1974 Mazda RX-4
1972–1980 Mazda Luce
1978–1979 Mazda RX-7, 100 hp (75 kW)
Lean-burn
1979–1985 Mazda RX-7 (Japan)
1980–1985 Mazda RX-7 (USA)
6PI
1981–1985 Mazda Luce
1981–1985 Mazda Cosmo

[edit] Turbo
The ultimate 12A engine was the turbocharged and fuel injected engine used in the Japan-spec HB series Cosmo, Luce, and SA series RX-7. In 1982 a 12A turbo powered Cosmo coupe was officially the fastest production car in Japan. It featured "semi-direct injection" into both rotors at once, a technique that was much more successful than it would appear. A passive knock sensor was used to eliminate detonation, and later models featured a specially-designed "impact turbo" which was tweaked for the unique exhaust signature of the Wankel engine. The engine continued until 1989 in the HB Cosmo series but by that stage it had grown a reputation as a thirsty engine.

Output was 165 hp (123 kW) at 6000 rpm and 186 Nm (137 ft·lbf) at 4000 rpm.

Applications:

1982–1989 Mazda Cosmo
1982–1985 Mazda Luce
1984–1985 Mazda RX-7

[edit] 12B
The improved 12B was quietly introduced in 1974. In the US it was the start of the single distributors engines.

NOTE: the previous 12A & 10A engines used the twin distributors.

Applications:

1974–1978 Mazda RX-2
1974–1978 Mazda RX-3

[edit] 13B
The 13B is the most widely produced engine. It was the basis for all future Mazda Wankel engines, and was produced for almost 30 years. The 13B is no relation to the 13A. Instead, it is a lengthened version of the 12A, having 80 mm (3.1 in) thick rotors. It had the largest displacement yet at 654 cc, for a total of 1308 cc.

In the United States, the 13B was available from 1974 through 1978 and was then retired until the 1984 RX-7 GSL-SE. It disappeared from the US market again in 1995, when the last US-spec RX-7s were sold. The engine was continually used in Japan from 1972's Mazda Luce/RX-4 through 2002's RX-7.


[edit] AP
The 13B was designed with both high performance and low emissions in mind. Early vehicles using this engine used the AP name, which signified these two characteristics..

Applications:

1975–1980 Mazda Cosmo AP
1974–1977 Mazda Rotary Pickup
1975–1977 Mazda Roadpacer
1973–1978 Mazda RX-4
1975–1980 RX-5

[edit] 13B RE-EGI
A tuned intake manifold was used in a Wankel engine for the first time with the 13B RE-EGI. The so-called Dynamic Effect Intake featured a two-level intake box which derived a supercharger-like effect from the Helmholtz resonance of the opening and closing intake ports. The RE-EGI engine also featured Bosch L-Jetronic fuel injection. Output was much improved at 135 hp (101 kW) and 133 ft·lbf (180 N·m).

Applications:

1984–1985 Mazda HB Luce
1984–1985 Mazda HB Cosmo
1984–1985 Mazda FB RX-7 GSL-SE

[edit] 13B-DEI
Like the 12A-SIP, the second-generation RX-7 bowed with a variable-intake system. Dubbed DEI, the engine features both the 6PI and DEI systems, as well as four-injector electronic fuel injection. Total output is up to 146 hp (109 kW) at 6500 rpm and 138 ft·lbf (187 N·m) at 3500 rpm.

Applications:

1986–1988 Mazda RX-7, 146 hp (108 kW)
1989–1991 Mazda RX-7, 160 hp (119 kW)

[edit] 13B-Turbo
The 13B-DEI was turbocharged in 1987. It features the newer four-injector fuel injection of the 6PI engine, but lacks that engine's eponymous variable intake system. The twin-scroll turbocharger is fed with a two-stage valve to reduce turbo lag. Output is way up at 185 hp (138 kW) at 6500 rpm and 183 ft·lbf (248 N·m) at 3500 rpm.

Applications:

1986–1991 Mazda HC Luce Turbo-II, 185 hp (138 kW)
1987–1988 Mazda FC RX-7 Turbo-II, 185 hp (138 kW)
1989–1991 Mazda FC RX-7 Turbo-II, 200 hp (147 kW)

[edit] 13B-RE
The 13B-RE was first series production twin sequential turbo systems to be offered for sale.

Applications:

1990–1995 Eunos Cosmo, 235 hp (176 kW)

[edit] 13B-REW
A twin-turbocharged version of the 13B, the 13B-REW, became famous for its high output and low weight. The twin Hitachi HT-12 turbos were operated sequentially, with the primary providing boost until 4,500 rpm, and the secondary coming online afterwards. Output eventually reached, and may have exceeded, Japan's "maximum" of 280 DIN hp (206 kW) for the final revision used in the series 8 Mazda RX-7.

Applications:

1992–1995 Mazda RX-7, 255 hp (190 kW)
1996–1998 Mazda RX-7, 265 hp (197 kW)
1999–2002 Mazda RX-7, 280 hp (206 kW)

[edit] 20B

Eunos Cosmo engine at the Mazda Museum
Rotary Engine 20BIn Le Mans racing, the first three-rotor engine used in the 757 was named the 13G.

The main difference between the 13G and 20B is that the 13G uses a factory peripheral intake port(used for racing) and the 20B uses side intake ports.

It was renamed 20B after Mazda's naming convention for the 767 in November of 1987.

The three-rotor 20B-REW was only used in the 1990-1995 Eunos Cosmo. It was the world's first volume production twin-turbo setup featured in both 13B-REW & 20B-REW form. It displaced 1962 cc (three 654 cc rotors) and used 0.7 bar (around 10psi)of turbo pressure to produce 300 hp (224 kW) and 300 ft·lbf (402 Nm).


[edit] 13J
The first Mazda racing four-rotor engine was the 13J-M used in the 1988 and 1989 (13J-MM with two steep induction pipe) 767 Le Mans prototypes.[1] This motor was poorly designed, and was replaced by the 26B.


[edit] R26B
The most prominent 4-rotor engine from Mazda was used exclusively for various Mazda-built GT cars (including the 767 and 787B) in replacement of the older 13J. In 1991 this engine in a 787B became the first from outside the U.S. or Western Europe and the first (and so far only) car with anything other than a reciprocating engine to win outright the 24 hours of Le Mans race. It displaced 2622 cc and built 700 hp (522 kW) at 9000 rpm. The engine design originates as a single 13B with: an additional rotor and housing added at each end, continually variable geometry intakes, and an additional (third) spark plug per rotor. The R26B's rotor housing can be purchased at retail from Mazdaspeed, but no internal parts are available to the general public.


[edit] 13B-MSP RENESIS

Mazda RENESIS prototype in the Mazda MuseumThe RENESIS engine – also 13B-MSP, for Multi Side Port –, which first appeared in production in the 2003 Mazda RX-8, is an evolution of the previous 13B. It was designed to reduce exhaust emission and improve fuel economy, which were two of the most recurrent drawbacks of rotary engines. Unlike its predecessors from the 13B range, it is naturally aspirated, leading to lower power from its two versions (Mazda RX-7's twin-turbocharged 13B-REW (280hp).

The engine entailed two major changes. First, the exhausts ports are no longer peripheral but are located on the side of the housing, which allowed engineers to eliminate overlap and redesign the intake port area. This produced noticeably more power, thanks to a better compression ratio. Second, the rotors are shaped differently, especially their side seals and low-height apex seals, which offer optimized lubrication.

These and other innovative technologies allow the RENESIS to achieve 49% higher output and dramatically reduced fuel consumption and emissions (the RX-8 meets LEV-II). It won International Engine of the Year and Best New Engine awards 2003 and also holds the "2.5 to 3 litre" size award for 2003 and 2004, where it is considered a 2.60 L engine. Finally, it was on the Ward's 10 Best Engines list for 2004 and 2005.

The RENESIS has also been adapted for a dual-fuel use, allowing it to run either on gasoline or hydrogen.


[edit] 16X

Mazda TaikiAlso known as the RENESIS(2), made its first (and so far only) appearance in the Mazda Taiki concept car.

The Mazda press release regarding the engine:

Next Generation RENESIS (Rotary Engine 16X) In developing the next-generation RENESIS, Mazda made a thoroughgoing revision of engine dimensions including the trochoid rotor housing, adopting a longer stroke and larger displacement of 1600cc (800cc x 2) aimed to raise thermal efficiency and boost torque at all engine speeds. By employing the Hydrogen RE design policy of a direct injection system and aluminum side housing, as well as various other measures, we are further promoting the rotary engine’s merits of light weight and compact size.


[edit] Sales

Annual Mazda Wankel "rotary" engine sales (data source: Ward's AutoNews)Mazda was fully committed to the Wankel engine just as the energy crisis of the 1970s struck. The company had all but eliminated piston engines from its products in 1974, a decision that nearly led to the company's collapse. A switch to a three-prong approach (piston-gasoline, piston-Diesel, and Wankel) for the 1980s relegated the Wankel to sports car use (in the RX-7 and Cosmo), severely limiting production volume. But the company has continued production continually since the mid-1960s, and is the only maker of Wankel-powered cars (the RX-8) today.

Though not reflected in the graph at right, the RX-8 is a higher-volume car than its predecessors, and Mazda is considering adding more Wankel models. The company has also developed a hydrogen-powered version of the Renesis. Though sales leveled off in the 1990s, these factors could cause the Wankel to again be a substantial force in the automotive market.

Mazdaspeed Cars.

Mazdaspeed is Mazda's in-house race and street car tuning arm. It began in 1968 as "Mazda Sports Corner", a tuning and racing operation run by Takayoshi Ohashi, who also ran Mazda's Tokyo distributor. They competed in numerous events at home and abroad, and they were also competitive at the 24 Hours of Le Mans races in the early 1980s with the 717, 727, and 737 before Mazda brought the group to Hiroshima in 1990. In 1991, Mazdaspeed's 787 won at Le Mans, a feat no other Japanese team has managed.

After the FIA effectively outlawed the Wankel engine the next year, the Mazdaspeed team turned away from professional racing and focused instead on enabling third-party competition of Mazda vehicles. Mazda assumed control of Mazdaspeed in 1999 as a tuning and performance parts operation within the company. In 2003, Mazda debuted its first consumer offered Mazdaspeed vehicle, the 2003 Mazdaspeed Protegé. It was only released to the North American market as an upgrade to the Protegé MP3 and it offered more power — from the MP3's 140 bhp (104 kW) to 170 bhp (127 kW) — by using a T25 Callaway-Garrett turbocharger and an intercooler. It is also worth noting that a 2003.5 model year was produced with a new range of colours and a new, more stylish exterior. Some modifications included new front air dam and a new spoiler. A year after, in 2004, another Mazdaspeed model was offered, the Mazdaspeed MX-5 Miata; it too was released only in the North American market. It featured an IHI single-scroll turbocharger producing 8.5 psi of boost to further increase power, from 142 bhp (106 kW) to 178 bhp (133 kW) and torque from 125 lb·ft (169 N·m) to 166 lb·ft (225 N·m). Mazda soon realized that these high performance models could be successful outside of North America and would make the next vehicles available worldwide.

In 2006 the Mazdaspeed 6 was released globally; it featured the most powerful piston engine ever produced by Mazda at 274 bhp (204 kW) and all-wheel drive. A 2007 Mazdaspeed 6 model joined a new vehicle, the Mazdaspeed 3 — which, with 264 bhp (197 kW) and 280 lb·ft (380 N·m) of torque, was the most powerful vehicle in its class.

Mazda B engines

The 1995 BH model was available internationally (The BH model was released for the Japanese Domestic Market the previous year, in 1994) with both front wheel drive and all wheel drive. Production of this generation started on August 8, 1994, and ceased on June 18, 1998.


However, Japan did see an unusual model with this generation after 1995, with the cancellation of the 1985-generation station wagon. The Mazda Familia Van offered after this year was a rebadged Nissan Sunny California, which was essentially the station wagon version of the Nissan Sunny.


This generation of Familia grew considerably, with the four-door sedan's wheelbase only a few millimetres short of the then-current Toyota Camry, a mid-size car.


The rare North American ES model is the only Protegé that came with the Miata's 1.8-liter twin-cam engine (though the internals were not the same), 4-wheel disc brakes, and dual stabilizer bars.

323F/Astina/Lantis


A five door hatchback and four door sedan, both featuring pillarless doors and distinct sheetmetal from other 323s was sold in Japan as the Mazda Lantis, in Australia and South Africa as the Mazda 323 Astina, in Colombia as the Mazda Allegro and in Europe as the Mazda 323f. They were built on platforms distinct from the other 323s. The bodyshape was designed by former Porsche designers. The Lantis was on the CB, a minor update of the CA that underpinned the luxury Mazda Xedos 6 and Eunos 500. The European 323f was designated BA, but was actually almost identical to the CB, and had little to do with other B platforms. These models were sold with the 1.5 L and 1.8 L engines seen in the rest of the 323 range, as well as a 2.0 L V6 shared with the Eunos 500.

Familia Neo/323c/Laser Lynx


The Familia Neo started production for the Japanese Domestic Market in 1994. Ford released a rebadged version which was mechanically the same although different bumpers, headlights and bonnet were fitted, badged as the Ford Laser-Lynx in Japan and Australia. This model was only available as the Ford Laser-Lynx in the Australian market, as Mazda already had the 323 Astina Hatch filling the gap for a hatchback in the Mazda range. Oddly enough to contradict this, Mazda Australia also offered two 323 sedans, the Astina/Lantis hardtop and the 323 Protege until production of both models ceased in 1998. This was released new in New Zealand as the Mazda 323 Neo. It featured a glass rear hatch, much like the Honda CR-X. Aesthetically the Familia Neo was very close in looks to a Mazda Lantis/323F and equated to a 2 door version and also shared the Lantis suspension. The top spec Mazda Neo was fitted with a DOHC 1800 cc BP engine which produced around 100kw, this was the same engine fitted to the base model Mazda Lantis. It was also sold for a single year (1995) in Canada as 323 Neo GS. In Europe it was named Mazda 323 C (stand for coupe) and it was equipped with 1.3 L SOHC (75 PS), 1.5 L DOHC 16V (88 PS), and 1.8 L DOHC 16V (115 PS) engine.
