Chronology
Predecessor Matra Bagheera

The Peugeot Murena is a mid-engined, rear wheel drive sports car that was produced from 1980 through 1983 by the French engineering group Peugeot. The factory was located in the commune of Romorantin-Lanthenay in the department of Loir-et-Cher in central France.

Development history

The Murena, whose name is Italian for "Moray", was the successor to the Matra Bagheera, a similar vehicle that resulted from an earlier collaboration between Matra and Simca. Development proceeded under two project names; "M551" for the 1.6-litre version and "M552" for the 2.2-litre version. [3] The prototype received designation P-551 and was accompanied by a series of mockups. The Murena inherited the Bagheera's mid-engined layout and hatchback body shape, but substantial changes were made to address some of the problems with the previous model, among which were a lack of power, absence of a 5-speed transmission option, and a chassis extremely prone to rust. Engineering of the car was done entirely by Matra. [3] Greek industrial designer Antonis Volanis, who had contributed to the interior of the earlier Bagheera and been principal designer for the Matra Rancho, headed up the design.

The Murena drew heavily from the corporate parts bin, using engines from the Talbot Solara and Talbot Tagora, a transaxle developed by Citroën for their Citroën CX and also used in some Lancia Beta models, Talbot Horizon taillamp clusters fitted with custom lenses, steering rack and front suspension from the Talbot Solara, front indicator and running lights from the Renault 12, and door handles from the Peugeot 505. [4] [3]

Features

Chassis

The Murena's chassis was a new design. [3] In appearance it was very close to a full unitary body. The chassis differed from the Bagheera's in two significant ways; the rear cradle was reconfigured to accommodate a new rear suspension system, and the entire chassis was galvanised to prevent the Murena from falling victim to the rust problems that plagued the Bagheera. [5] The Murena was the first production car to use galvanised steel for all chassis parts.

The car was only built in a left hand drive configuration, although a small number of right hand drive conversions were done by Wooler-Hodec. [6]

Bodywork

Like the chassis, the styling for the Murena was all-new. The final shape was very aerodynamic for the time, with a reported drag coefficient () of 0.328. [5] [4] The rear hatch opened to provide access to the engine mounted behind the passenger compartment and a rear luggage area. A signature feature carried over from the previous model was the seating arrangement - all three seats were placed in one row, with the middle seat folding down to become an armrest when not in use by a passenger. [7] In the Murena the three seats were separate, in contrast to the 2+1 arrangement in the Bagheera.

The car's twelve major body panels were made of fibreglass-epoxy. According to Matra's general manager, Jean-Louis Caussin, these body panels were produced using a manufacturing process known as the "sheet moulding compound" moulding process. [3] The new galvanised chassis coupled with the composite panels made the car essentially immune to rust, except for the rear suspension's trailing arms. [7]

Over its production life the car was offered in a range of ten colours; platinum metallic, white neve, coral metallic, green Hudson, bordeau, red mephisto, titanium gray, cinnamon metallic, yellow mimosa, and blue Colombia.

Suspension

The front suspension was similar to the Bagheera's, while the rear suspension was a departure from the Murena's predecessor. In the tradition of the Simca 1100, Talbot Alpine, and Talbot Horizon, at the front were upper and lower transverse A-arms with longitudinal torsion bars and telescopic hydraulic shock-absorbers. An anti-roll bar was also fitted. At the rear, the Bagheera's torsion bar suspension was replaced by semi-trailing arms with coil springs mounted on telescopic hydraulic shock absorbers. An anti-roll bar was also fitted at the rear.

Powertrain

Two engines were offered. The base model had a 1.6-litre Poissy engine, while the more powerful version came with a 2.2-litre Type 180. The 2.2-litre engine could also be ordered with a performance package called the "Préparation 142" option that raised the power output from 118 PS (87 kW) to 142 PS (104 kW). This kit was initially a dealer-installed option, but the last 480 Murenas came with this uprated engine directly from the factory. This version was called the Murena S. [5] The standard 2.2-litre engine used a single Solex down-draught carburetor, but S models had twin side-draught Solex carburetors.

The Murena received a 5-speed manual transaxle derived from that of the Citroën CX (or depending on the model year the Lancia Beta). Different models of Murena used different final-drive ratios but all Murenas used the same transaxle.

Driving impressions

In the May 1981 issue of Car magazine, in an article titled "Murena the marvellous", automotive journalist LJK Setright described the Murena as being "endowed with a suspension so superb that it need never go slowly". He also wrote that, although not a sprinter, when it came to sustaining high speeds on winding roads "the Murena ranks high — better than the basic Porsche 924, every bit as good as the Lancia Monte Carlo, and losing only in sheer agility to the Fiat X1/9, while it shows up the Porsche 911 as ill-balanced and inept" and went on write that this "is one of the most sweetly responsive cars that ever offered a driver a choice of how to steer through a bend." In the end he felt that the car would benefit from more power. [8]

Model year changes

Production numbers

Production of the 1981 model-year Murena 1.6 began in November 1980, followed a few months later by the 2.2. Production of the Matra Murena ended in July 1983, when the Matra factory switched over to building the first generation of Renault Espace minivan.

Prototypes and specials

Motorsports

In 1981, a Murena prepared by Politecnic and equipped with an engine built by Bernard “Nanard” Mangé and Dany Snobeck (operating under the name “SODEMO”) was entered in the Rallye Monte Carlo. This was with limited result and the car retired early.

Later the same car was entered in the 1981 1000 Pistas (laps) Rally. The car was driven by Jean-Pierre Beltoise and the co-driver was singer Véronique Jannot. The car retired early, due to failed engine mounting. [12]

Cars were prepared by Marcel Morel (Maurelec) and Politecnic for the French Rallyecross championship, of which Morel was the only one to use a Murena 1.6 as the base model, Politecnic only used modified 2.2s, either with ROC engines or SODEMO prepared engines.

Race-tuned Murenas prepared by Politecnic produced the following results:

3 French Rallycross championship titles
1 European Champion title (2nd division)
1 French Mountain Cup championship

Drivers included Jean-Pierre Beltoise, Max Mamers, Rémy Julienne, Jean-Pierre Jaussaud, Johnny Servoz-Gavin, Jean-Claude Andruet, Marcel Morel and Philippe Wambergue. [13]

Nowadays more frequently called 'RMR', to acknowledge that certain sporty or performance focused front-engined cars are also "mid-engined", by having the main engine mass behind the front axle, RMR layout cars were previously just called MR, or mid-engine, rear-wheel-drive layout), because the nuance between distinctly front-engined vs. front mid-engined cars often remained undiscussed.
