The 2.5-litre straight-six runs on gasoline and returns about 13 litres per 100 km. Tank holds 39 to 44 litres depending on source data. Smooth and reliable for long runs at 100 km/h cruise.
Servicing details are sparse in the record. The engine uses pressure lubrication and a downdraft carburetor. Three-speed gearbox has synchromesh on second and third. No fixed intervals appear in period specs.
Safety relies on hydraulic four-wheel drum brakes and a rigid steel body with one-piece roof. Independent front Dubonnet-type suspension plus rear leaf springs and hydraulic dampers aid control. No crash-test ratings exist for the era.
Keeping the car means checking the mechanical camshaft-driven wipers, 6-volt electrics, and chassis lubrication points. Separate frame allows body work. Parts remain available through classic networks for the simple OHV six.
