Among the Mercedes offerings of 1911 was the 22/40 PS, or, in American parlance, a 40 HP model, returning that figure at 1,230 rpm from a 5,623-cubic-centimeter T-head four-cylinder engine with dual camshafts, pressurized cooling, and dual ignition by magneto and battery. Initially, upon its introduction in 1910, the model had used a “modern” shaft drive, but it was soon made available with the romantic dual chain drive, as well—a “Colonial” configuration that offered a higher ground clearance and wider track for less ideal roads. It was the type of automobile that came to define the early Mercedes: an extremely well-engineered luxury machine, beautifully designed and very solidly built, and capable of excellent performance.

The 22/40 HP model offered here is documented by copies of its original Mercedes build documents, listing it as constructed with the chassis and engine numbers that it retains to this day for Robert & Co. of Frankfurt. It was intended directly for an Argentinean client, with the detailed build specifications requesting instruction plates lettered in French, German, and Spanish, as well as larger tires, accommodating the Colonial specification. It was afterward shipped to Buenos Aires by Heinrich Rüppel & Sohn, an export company in Bremen.

In the late 1960s the Mercedes was offered to the Indianapolis Motor Speedway Museum by a Ricardo C. Bieler of Santa Fe, Argentina, beginning a negotiation that continued until the car was at last acquired for the Museum in the spring of 1971. It was subsequently shipped aboard the Nopal Progress from Argentina to the Port of New Orleans, from which it embarked by land to its final destination in the Hoosier State. Fascinating correspondence regarding the acquisition and shipment is included in the history file.

The Mercedes was afterward restored under the auspices of the Museum and has remained on occasional exhibit over the years, as well as frequently brought to events, including, in 2003, the Pebble Beach Concours d’Elegance. Its restoration is of course older in presentation, but following recent recommissioning is in good running order. Most significantly the car remains astonishingly proper for a Mercedes of its era, retaining the original carburetor, ignition system, switch panel, hardware, and fittings, down to the flooring in the driver’s compartment and even its Mercedes coachwork tag. Repairs to the wheels and rims, as well as sourcing correct tires, would be recommended for the new owner.

This is a splendid example of the Brass Era Mercedes, a legendary piece of exceptional engineering and design—ideal as a tour machine for its fortunate new owner.
