RX-2
The RX-2 was Mazda's first true rotary passenger
car. Released in Japan on the 13th of May 1970 as the R612, a designation
combining the rotary 12A and the piston 1600. Two weeks later Mazda strangely
changed its direction from the R100, 110S and the R130 theme to rename its
rotary version the RX-2. The Capella name was taken from a star. This led to
marketing slogans such as the "Star of the Highways". Capella is also the name
of an African Antelope, which is represented in the badges.
Mazda Australia released the Series I RX-2 in October 1970. Model specs were the
Deluxe (D) and Super Deluxe (SD) sedan plus the Super Deluxe Coupe. Prices were
$2998 for SD sedan and $3298 for the SD coupe.
The RX-2 had its 'M' symbol surrounded by a rotor where the Capella had its 'M'
symbol inside a circle. Due to larger porting and an extractor-type cast iron
manifold, Aussie 12As made 130hp. Mixed with 950kg (SD coupe), the RX-2 was
reasonably quick at 16.3 seconds for the quarter mile. Still with this sort of
performance the RX-2 was far beyond the opposition in its class. In order to
find a comparable game, the little car had to go hunting for bigger fish like
the Holden GTR-XU1 Torana, Ford Capri V6 or the Valiant Pacer 245.
The RX-2 opened the American market to Mazda. On introduction it won several
motoring awards including Motor Trends 'Import Car of the Year'. Initially,
demand for the RX-2 exceeded supply, and some Mazda dealers were selling RX-2s
well above sticker price. This was primarily caused by an inadequate
dealer/distribution network. It wasn't until mid 1972 that Mazda organized an
efficient dealer network.
From February 1972 the Series I became available with optional 3-speed auto
transmission. The Jatco automatic slowed the RX-2 by only 1.2 seconds down the
quarter mile. The auto option sold well. On its introduction the auto RX-2 cost
only $3814; this was at the time, amazing value.
Mazda Australia introduced the Series II in late 1972, the Series II was
instantly recognisable by its twin headlight front. Apart from the twin
headlights the only other differences are to be found in the way the chassis
number is stamped flush on the firewall for the Series I and raised for the
Series II.
In late 1973, the Series III arrived on the Japanese market. There were big
changes for the RX-2 this time. Firstly, under the bonnet was the newly
developed single dizzy 12A. Really known as the 12B; however, due to the
millions spent on marketing, the 12A name stayed. An added feature was the
Rotary Engine Anti-Pollution System or REAPS. A five-speed manual gearbox became
an option on RX-2s. The interior received considerable updating including an
oversized RX-4 steering wheel. Suspension setting were altered and quite notably
the taillights were changed to meet 1974 Japanese government regulations.
The Series III arrived in early 1974. Australian models found all the extra
interior updates, including the 12A single dizzy plus its REAPS, wider 165SR13s
and a 3.9:1 diff ratio, previously reserved for the auto. The rear end treatment
followed the Japanese brake-indicator-brake-reverse taillight pattern. The major
rework of the Series III packed an extra 75kg onto the curb weight. With 1025kg
and still only 130 (official) hp, the RX-2 was slowed to 18.0 seconds down the
quarter mile.
To keep customers happy, Mazda offered a 2-year/40,000km warranty on the rotary
engine. Fortunately, the new 12B proved more reliable than the twin dizzy 12A.
The price rose marginally to $3668 for the manual and $3958 for the auto. Mazda
Australia's marketing people decided to drop the coupe from the line up. The
reasoning was to give the RX-3 coupe the sporty two-door image and keep the RX-2
in the medium-sized family-car bracket.
Mid 1974 saw release of the Series IV in Japan. Externally, the Series IV
carried an updated front end. A smooth pointed bonnet and RX-4 style grille with
RX-3 type headlights and surrounds gave the engine better cooling and great
looks for the RX-2 to finish out the decade.
Australia received the Series IV RX-2 at the end of 1974. However, due to the
slowed sales of the Series III (caused by delays in ordering of about 7-8 weeks,
the OPEC oil crisis and the RX-3 and RX-4 to choose from) customers had to wait
until mid 1975 before the first of the 19'74 models appeared in showrooms.
By this time the RX-3 was almost gone, RX-4 sales had slowed significantly and
the RX-5 was only a matter of months away. All up, Australian Mazda dealers sold
around 300 Series IV sedans. They continued to take orders up until April '76.
On the racing front, the RX-2 did well but due to the RX-3, its racing glory
didn't last. in July 1971 an RX-2 won its class finishing 3rd overall in the
Fuji 1000, while it won its class at Bathurst in '71 and '73.
A genuine RX-2 can be identified by the chassis number. It starts with the
prefix S122A whilst the Capella starts with SNA. There's the well known
taillight differences for the series I and II, but the only way to tell the
Series III and IV from the real thing is by the ROTARY ENGINE badge on the
grille and the rear beaver panel.
All RX-2s will have different rear muffler exit points when compared to the
Capella. RX-2s have a large 65 litre fuel tank, and the spare tyre is located
inside the boot on the floor. The Capella has a smaller 50 litre tank so it's
spare wheel is mounted under the boot. Because of room for the RX-2 muffler,
it's exit point will be about 15cm toward the center. There will also be a very
large cutout for the series III and IV models due to the REAPS rear muffler. The
steering box on a series III and IV will be unique to all the Capella and the
Series I and II. This is due to the REAPS thermal reactor requiring it to be
modified and repositioned for better clearance.
