Description
The Delahaye 135 M Cabriolet bodied by Pennock represents a unique and refined interpretation of one of France’s most celebrated luxury chassis. Produced during the late 1930s and into the postwar years, the 135 M (Modifiée) was known for its balance of performance and elegance. When combined with coachwork by the Dutch firm Pennock, it resulted in a cabriolet that was both understated and distinctive—an alternative to the more flamboyant French-bodied variants of the same model.
Under the bonnet, the Delahaye 135 M was equipped with a 3.6-litre straight-six engine. In typical configuration, this powerplant could produce between 100 and 130 horsepower depending on carburettor setup. The Pennock-bodied versions commonly featured the mid-range 115 horsepower specification, a versatile tune that provided brisk performance without compromising drivability. The engine was usually paired with either a four-speed manual transmission or Delahaye’s Cotal electromagnetic pre-selector gearbox, a technologically advanced option that allowed smooth, clutchless shifting.
The Pennock cabriolet body offered a restrained yet graceful aesthetic. Unlike the dramatic, sweeping forms of Figoni & Falaschi, Pennock’s design emphasized clean lines and a practical elegance. The front end featured a traditional Delahaye grille—tall and narrow, framed by subtle chrome trim and flanked by rounded fenders with integrated headlights. The bonnet was long and slightly domed, suggesting power without ostentation.
The side profile of the car was defined by gently curved body panels, a straight waistline, and a slight kick-up at the rear fenders. The folding fabric roof was well-integrated into the overall silhouette, with a tidy profile whether up or stowed. Chrome bumpers, simple door handles, and minimalistic side trim all contributed to a look of understated refinement.
Inside, the Pennock cabriolet provided a comfortable and well-appointed driving environment. The cabin typically featured leather upholstery in muted tones such as tan, oxblood, or grey, paired with varnished wood dashboard panels and classic instrumentation. Seating was arranged to accommodate two to four passengers, with generous legroom and a quiet ride aided by the cabriolet’s substantial construction and sound-dampening materials.
Driving the 135 M Cabriolet was a pleasurable experience, with the engine delivering smooth torque across the rev range and the chassis responding confidently to steering input. Independent front suspension and a well-tuned live rear axle provided a balance between comfort and control, suitable for long-distance touring or city driving alike.
Though less well-known than their French counterparts, Pennock-bodied Delahayes offered excellent craftsmanship and a tailored design suited to Northern European tastes. The coachbuilder, based in The Hague, had a reputation for quality work on luxury marques including Delahaye, Talbot-Lago, and Bentley.
Today, the Delahaye 135 M Cabriolet by Pennock is appreciated by collectors for its rarity, mechanical pedigree, and quiet sophistication. It reflects an era when even mid-sized grand tourers could be custom-built to the owner’s vision, resulting in automobiles that were as individual as they were beautiful.
