Porsche 356 B Carrera GTL Abarth
Nearing the end of the Fifties, Porsche’s 356 Carrera was losing pace to better peforming sets of wheels. To remain in the game Porsche understood that weight reduction and more aerodynamic efficiency were on call. The facts around these cars were though still very hazy. The most common viewpoint is that Porsche’s first port of call for their new machinery was Carlo Abarth, who had since long been working his magic on Fiat based machines, was approached in 1959 by Porsche to bless the German marques Carrera GT.
However, Porsche, under the assurance of Abarth, were originally led to believe that it would be Zagato fabricating bodywork for these new cars although the Milanese carrozzeria's contribution never materialised. Abarth commissioned ex-Bertone designer Franco Scaglione to come up with the re-profiled bodywork, and Rocco Motto in Turin to fabricate it. But Rocco's contribution was merely a fleeting one as, having manufactured the first three shells and received part payment for the entire run, he disappeared on what was described as an unplanned holiday. Production quickly got switched to another Turinese body builder, the little Viarengo & Filipponi works moving heaven and earth to complete the last eighteen aluminium shells. But after all the logistical problems of working with the Italian's, what became known as the GTL was able to do its talking on the track, securing a hat-trick of of Le Mans 24 Hour class victories between 1960 and '62.
The GTL in it's glory days, victory at LeMans
The first example was completed in late February 1960 and would have been finished sooner if only there had been sufficient space for the engine - its dimensions not having been taken into consideration when the prototype was designed back in Italy! All twenty one were built on chassis's and floor pans taken directly from Porsche's 356 B Carrera GT, this car featuring all-round independent suspension and hydraulically operated drum brakes although discs were quickly introduced, the factory using an experimental set on their works entry in 1960's Le Mans 24 Hours, the GTL's third race. Meanwhile, no less than five different engines were used in these cars between 1960 and '64, 1.6-litre motors initially with 115bhp being fitted but soon afterwards, both 128 and 135bhp units saw service, both with straight-through competition exhausts.
Even hotter two-litre versions with 155 and 180bhp were also plumbed into GTL's, but quite amazingly, even with the intermediate 128bhp 1.6 installed, Herbert Linge and Paul-Ernst Strahle were timed at 150.2mph down the Mulsanne Straight in 1960's Le Mans. Body-wise, the only existing parts carried over from the regular 356 were its headlamps although these were now set well back into the front wings and could be fitted with Plexiglas covers (which made the car look much prettier). Meanwhile, Scaglione's original elongated nose housed a prominent radiator duct flanked by two distinctive pods that were either used as brake-cooling channels or supplementary light bays.
Another interesting detail was the heavily louvred engine lid which, in true Abarth style, could also be propped open, some cars even featuring a cockpit-controlled rear lid mounted scoop located between the two highest banks of vents.
But although Scaglione was able to reduce the GTL's frontal area by 16% compared to the regular 356, instantly acquitting it with a far more drag resistant profile, it was certainly not a design to rival the prettiest Porsche and Abarth's. Inside, the cabins were spartanly finished, identical aluminium bucket seats to those of the GT normally being trimmed in black leatherette with velour centres, Porsche instruments being housed in a new lightweight aluminium dash. Binnacles of early GTL's featured two main dials, later models housing three, but all were fronted by an exquisite triple aluminium spoked, wood-rimmed Nardi steering wheel. Pretty uncomfortable for most tall drivers though, the GTL's cut-down windscreen meant headroom was at a premium. Various weight-saving measures ensured it tipped the scales around 50kg lighter than a regular Carrera GT, but the German marque were unhappy for a number of reasons, poor build quality, leaking seals and an insufficient steering radius convincing them that the collaboration with Abarth should go no further. However, they couldn't have been at all disappointed with the GTL's race record in the all-important World Manufacturers Championship. Indeed, GTL's would go on to take three consecutive class victories at Le Mans and no less than four in the Targa Florio. Meanwhile, Porsche also secured a hat-trick of class wins in the Nurburgring 1000km, Germay's highest profile endurance race of the year. There were three class wins at Sebring and two at Montlhery, GTL's also triumphing at Daytona, Bridgehampton, the Rossfeld Hillclimb and the Wiesbaden Rallye.
On a final note, there has been some disagreement in the past with regard to exactly how many GTL's were built. But twenty-one were eventually manufactured, their chassis numbers ranging from 1001 to 1021 although chassis 1019 was badly crashed when new and got subsequently rebuilt and renumbered as 1021, leaving us with twenty. Furthermore, chassis 1021 is believed to have been used in the rebuild of chassis 1002, the 1960 Targa Florio class winning car. Thus, whilst twenty-one GTL's were constructed, one was used in the reconstruction of another by Porsche and, in reality, only twenty ever existed at any one time.
special thanks to Mr. Sebastien Morliere, for the pics, though i don't know who he is, seems like a Porsche fan.
