1940 Dodge D14 Luxury Liner DeLuxe: 218-Cubic-Inch Flathead Six

Dodge built the D14 Luxury Liner for the 1940 model year around a 217.8-cubic-inch L-head inline-six rated at 87 bhp. Its separate frame, independent front suspension, hydraulic drum brakes, three-speed manual transmission, and 119.5-inch wheelbase reflected Chrysler Corporation engineering practice immediately before American automobile production turned toward wartime priorities.

Best known for combining Dodge's durable flathead-six drivetrain with the streamlined fender treatment and standardized sealed-beam headlamps of the 1940 model year, the D14 remains a practical entry into prewar Mopar collecting. The DeLuxe was joined by the more highly trimmed Special, while the broad body catalog included coupes, sedans, a convertible, and a wood-bodied station wagon.

For restorers, the D14 is particularly instructive because it predates Fluid Drive in Dodge passenger cars. Its conventional dry clutch and manual gearbox give it a simpler mechanical identity than the 1941 D19, while its modernized front suspension separates it from older Dodges whose chassis design was more firmly rooted in the early 1930s.

Quick Facts

The following summary identifies the core D14 specification. Body availability and trim details can differ among factory literature, body suppliers, and surviving cars, so individual examples should be checked against serial and body records.

The 218 name used by owners and parts suppliers is a rounded description of the 217.8-cubic-inch engine. It is useful when ordering mechanical parts, but the D14 series code remains the more precise way to distinguish the 1940 passenger-car line.

Why the D14 Matters

The D14 documents Dodge at the point where late-1930s streamlining met a still-conventional driveline. Sealed-beam headlamps sat neatly within the front fenders, the grille carried strong horizontal elements around a projecting center, and the cabin retained upright proportions even as the hood and body surfaces became smoother. Running boards remained, but the car no longer looked as vertically assembled as its early-1930s predecessors.

Mechanically, the car relied on components Dodge owners already understood: a long-stroke side-valve six, a single dry clutch, a manually shifted gearbox, and a live rear axle. Independent front suspension and four-wheel hydraulic brakes made that conservative powertrain easier to use on contemporary roads. The result was not a high-performance car, but a durable family automobile with straightforward service requirements and sufficient torque for the low road speeds and steep grades common in its period.

The 1940 model also marks a clear dividing line for collectors. Dodge offered Fluid Drive for 1941, altering the low-speed manners and mechanical presentation of the following D19 series. A correctly restored D14 therefore represents the last Luxury Liner configuration before Dodge adopted that fluid-coupling system.

Historical Context and Development

Dodge entered 1940 as Chrysler Corporation's sturdy mid-price make, above Plymouth in price and trim but below Chrysler and DeSoto in the corporate hierarchy. Its domestic competitors included Buick's lower-priced offerings, Oldsmobile, Pontiac, and Mercury, along with better-equipped models from Chevrolet and Ford. Buyers expected six-cylinder smoothness, a full-steel enclosed body, hydraulic brakes, and enough interior space for family use.

The D14 developed the themes introduced with the 1939 D11 Luxury Liner. Dodge had adopted independent front suspension and moved the gear lever from the floor to the steering column, freeing front-compartment space and giving the cabin a cleaner appearance. For 1940, federally standardized seven-inch sealed-beam lamps helped create a more integrated nose and improved lighting serviceability.

The body displayed the period's transition from separate visual components toward a more unified envelope. The headlights were faired into the fenders, the hood ran low between them, and the front fenders flowed back toward the doors. Closed cars retained a tall greenhouse and generous glass area, while restrained brightwork distinguished the better-equipped Special without changing the basic body structure.

Motorsport and homologation did not shape the D14. Dodge engineered it for everyday road use, dealer service, and high-volume family transportation. Its historical value comes instead from the rapid evolution of American production cars immediately before civilian output was curtailed during World War II.

Engine and Drivetrain

The D14 used Dodge's cast-iron L-head six, with both intake and exhaust valves located in the block beside the cylinders. A 3.25-inch bore and 4.375-inch stroke produced 217.8 cubic inches. The long stroke and modest compression ratio favored low-speed pulling ability rather than high engine speed.

A single downdraft carburetor supplied the mixture through a conventional intake manifold. Ignition came from a distributor and coil working through a six-volt electrical system. The pressure-fed lubrication system, water pump, radiator, fan, and thermostat were conventional but durable when maintained; accumulated scale in the block and water-distribution tube is now a more serious concern than the original system's capacity.

Power passed through a single-plate dry clutch to a three-speed manual transmission operated by a steering-column lever. Synchronization eased normal shifts in the upper ratios, while the propeller shaft carried drive to a hypoid-geared live rear axle. Fluid Drive was not part of the 1940 D14 specification.

The documented factory figures below describe the standard D14 engine rather than later replacement blocks or modified postwar installations.

Period references are not fully consistent on compression ratio and torque, partly because export specifications and running production details can be conflated with domestic data. Those figures should be confirmed against the applicable factory manual before an engine is machined or assembled.

Chassis, Suspension, and Braking

The D14 combined a separate steel frame with an all-steel body on most closed models. The station wagon was the conspicuous exception, using structural and decorative wood bodywork that now demands specialist inspection. Rubber body mounts isolated the passenger compartment, although collapsed mounts can distort panel alignment and transmit vibration.

Independent front suspension used coil springs, while the rear axle rode on longitudinal semi-elliptic leaf springs. The setup gave each front wheel greater freedom over broken pavement than an older beam axle, but retained the load-carrying simplicity of a leaf-sprung rear end. Steering remained manual, with a large-diameter wheel providing the leverage expected before power assistance.

Hydraulic drum brakes operated at all four wheels. Correct adjustment matters because these systems depend on shoe centering, sound wheel cylinders, flexible hoses, and properly finished drums. A D14 with a hard or wandering pedal often needs more than a routine bleed.

These chassis figures are useful when checking a candidate car for incorrect wheels, altered stance, or a misidentified body mounted on another frame.

Body style and optional equipment affected weight, spring loading, and tire requirements. A restorer should use the body-specific parts book rather than assume that every component interchanges across all D14 derivatives.

Driving Experience and Handling Dynamics

A properly rebuilt flathead six starts with a muted churn and settles into a low idle with little mechanical drama. Throttle response is deliberate rather than sharp. The long stroke supplies useful pull from low engine speed, so the driver can use third gear over much of an open road instead of chasing revs.

The column shift works best with an unhurried hand and a fully released clutch. Worn linkage bushings produce vague gate selection, while rushed downshifts expose the limits of a prewar gearbox. When correctly adjusted, the mechanism should not require force or repeatedly fall out of gear.

At parking speed, the steering is heavy, particularly with underinflated modern reproduction tires. Once moving, the large wheel and conservative geometry deliver steady directional control, but not rapid response. Body roll arrives early by modern standards, while the independent front suspension allows the car to absorb rough surfaces without the steering kick associated with a solid front axle.

The brakes require planning. A sound hydraulic system provides progressive stopping for the car's intended speeds, yet pedal effort, drum heat, and narrow tire contact patches discourage late braking. Loose kingpins or control-arm pivots, incorrect toe, worn shock absorbers, and aged tires can make a tired example feel far less composed than Dodge intended.

Identification and Originality

A D14 should be identified by its factory serial number rather than by treating its body tag or engine stamp as a modern 17-character VIN. Surviving cars generally carry a serial-number plate on the body, while the engine number is stamped on a machined boss on the block. Plate location, number sequence, and stamping form should be checked against Dodge service literature and Chrysler historical records applicable to the assembly plant.

Engine numbers did not duplicate the vehicle serial number in the modern sense. A surviving original engine can still be documented through factory records, but advertisements claiming matching numbers need supporting paperwork rather than a visual assertion. Flathead-six replacements were common because closely related Dodge, Plymouth, Chrysler, industrial, and military-family engines remained serviceable for decades.

Block length, displacement, external accessories, and casting details deserve examination. A later 230-cubic-inch engine may fit with varying degrees of adaptation and can look convincing after paint and accessory changes. The engine-number prefix, bore and stroke where necessary, and casting dates provide better evidence than cylinder-head lettering alone.

Body tags may identify the body supplier, style, and production sequence, but they are not substitutes for the chassis serial plate. Closed bodies, open bodies, and wood-bodied wagons used different construction details. Replacement doors, front clips, grilles, and fenders can also blur trim distinctions because D14 parts were frequently exchanged while the cars were ordinary used transportation.

Trim, Paint, and Cabin Details

The Special received additional brightwork and upgraded interior appointments over the DeLuxe, but exact equipment should be checked against body-style literature. Surviving cars often mix Special garnish moldings, wheel covers, lamps, and upholstery with DeLuxe bodies. Dealer accessories further complicate identification.

Original paint should be researched from period Dodge color literature, build documentation, and evidence found under weatherstrip, garnish moldings, hinges, or trunk fittings. A modern color described merely as close to factory is not the same as a documented period formula. The same principle applies to woodgraining, mohair or broadcloth upholstery, rubber floor coverings, running-board mats, and trunk materials.

Date codes on glass, distributor bodies, generators, voltage regulators, carburetors, and other components can support a restoration, although service replacements are normal on an 80-year-old automobile. Chrysler Historical Services records, when available for a particular serial number, are substantially more useful than unsupported claims based on trim alone.

Variant and Trim Breakdown

The D14 series was sold in two principal trim levels rather than separate performance specifications. Body-style catalogs were broad, and availability could differ by trim, so the table concentrates on distinctions that can be stated without assigning unsupported production totals.

Exact D14 production by trim and body style is not consistently documented in readily available summaries. The station wagon and convertible have much lower survival rates than ordinary sedans, but rarity should be established through body records rather than a seller's estimate.

Performance and Dimensional Specifications

Dodge promoted smoothness, durability, and economy rather than publishing the standardized acceleration tests expected of later cars. Body style, axle ratio, tire size, road surface, and engine condition materially affect any surviving period performance figure.

Reliable factory-standardized 0-to-60-mph, quarter-mile, and top-speed figures are not consistently documented for the full D14 body range. Likewise, factory literature often reported shipping weight by body style rather than one universal curb weight, so a single figure would misrepresent coupes, sedans, convertibles, and wood-bodied wagons.

Compared With Related Dodge Models

1939 D11 Luxury Liner

The D11 introduced the Luxury Liner name for 1939 and established much of the engineering direction carried into the D14. Both used Dodge's flathead-six formula and independent front suspension, but the 1940 car is immediately distinguished by its sealed-beam headlamps and revised frontal treatment. The D14 is usually easier to recognize from the front than from a distant side profile.

1941 D19 Luxury Liner

The D19 followed for 1941 with revised styling and the availability of Fluid Drive. That fluid coupling allowed the driver to remain in gear while stopped without depressing the clutch, although the car still used a conventional transmission and clutch in the driveline. Buyers seeking the simplest prewar Dodge arrangement often prefer the D14's direct dry-clutch system, while others value the D19 for its early Fluid Drive association.

Contemporary Plymouth and Chrysler Products

Plymouth models from the same corporate family shared broad engineering principles and certain service practices, but their components should not be assumed interchangeable without part-number confirmation. Chrysler and DeSoto models could use longer blocks, different wheelbases, and different trim hardware. A flathead six that looks correct at first glance may therefore be mechanically or dimensionally wrong for a D14.

Ownership and Restoration Notes

Routine mechanical parts are generally easier to source than model-specific trim. Ignition components, brake cylinders, bearings, gaskets, clutch parts, and many flathead-six service items remain available through specialist suppliers. Correct grille pieces, hood ornaments, gauge components, die-cast trim, body-specific glass, and convertible hardware can require long searches or the repair of original parts.

Cooling-system restoration should include the block as well as the radiator. Sediment accumulates around the rear cylinders, while the water-distribution tube behind the water pump can corrode or clog. A freshly recored radiator cannot compensate for restricted internal water passages, a damaged tube, incorrect ignition timing, or a lean fuel mixture.

Engines should be checked for freeze damage, cylinder-head cracks, low oil pressure, valve sticking, worn timing components, and excessive crankshaft or connecting-rod clearance. Before ordering pistons or bearings, a machine shop familiar with Chrysler flatheads should measure the block and determine whether it has already been bored or had its crankshaft reground.

Transmission complaints often originate in worn column-shift linkage rather than the gearbox itself. Inside the transmission, bearings, synchronizer parts, gears, and shafts require inspection. The clutch linkage, engine mounts, universal joints, rear-axle seals, and pinion condition also influence driveline noise and shift quality.

Structural corrosion appears in floors, sills, rocker areas, body mounts, trunk edges, lower doors, fender attachment points, running-board supports, and the cowl. Sedans are usually manageable for an experienced body shop, but a station wagon requires a restorer capable of reproducing structural wood with correct joints, profiles, hardware, and finish. Decorative carpentry alone is not sufficient.

There is no single modern service interval appropriate to every restored D14. The factory lubrication chart remains the correct starting point, supplemented by frequent inspection of brake fluid, wheel bearings, steering joints, coolant condition, fan belt, ignition points, and chassis lubrication after storage or limited seasonal use.

Buyer and Inspection Points

A D14 purchase should begin with identity and structure, not with whether the engine starts. Cosmetic restoration can exceed the cost of rebuilding the familiar flathead drivetrain, especially when rare trim or open-body hardware is absent.

A complete, non-running car with sound structure and intact trim can be a better restoration prospect than a running example assembled from several models. Documentation, old registrations, service records, photographs, and Chrysler build information add confidence when trim or drivetrain components have changed.

Collector and Market Relevance

Four-door sedans account for much of the visible survivor population and generally provide the most accessible route into D14 ownership. Coupes attract traditional hot-rod and custom interest, which makes unmodified bodies increasingly desirable to originality-focused collectors. Convertibles and wood-bodied station wagons command attention because far fewer have survived and because correct restoration is substantially more difficult.

Collectors usually reward an intact grille, correct dashboard, documented serial identity, proper flathead-six installation, original-style upholstery, and restrained paintwork. Mechanical upgrades such as a later engine, modern electrical conversion, overdrive transmission, or disc brakes may improve usability for an individual owner, but they alter the evidence of how a 1940 D14 was built and operated.

The model lacks a major competition pedigree, and its appeal does not depend on one. It represents a high-volume American passenger car whose engineering can still be understood, rebuilt, and driven without electronic systems or exotic materials. The rare body styles add scarcity, while the sedans preserve the everyday context in which most Dodges actually worked.

Cultural Relevance

The D14 belongs to the final full model year before American industry accelerated toward defense production. Many cars of this age later endured wartime fuel and tire rationing, postwar scarcity, and decades of inexpensive used-car service. Survival with original trim, upholstery, woodwork, or drivetrain components is consequently more meaningful than mileage claims that cannot be documented.

Dodge coupes and sedans of this period also entered postwar hot-rod and custom culture. Engine swaps, lowered suspension, hydraulic-brake updates, and modified interiors kept some bodies on the road but consumed original cars. Today, clubs devoted to Chrysler products and the broader Antique Automobile Club community provide technical knowledge that factory dealerships no longer can.

Film and period-street recreations often use prewar sedans as background vehicles, yet the D14 is frequently misidentified as a Plymouth or as a generic 1940 Dodge. Its grille form, D14 serial identity, Dodge badging, and body details are needed for a defensible identification.

Frequently Asked Questions

What engine is in the 1940 Dodge D14 Luxury Liner DeLuxe?

The standard domestic D14 used a 217.8-cubic-inch L-head inline-six, commonly called the Dodge 218, rated at 87 bhp at 3,600 rpm. It used a single downdraft carburetor and drove the rear wheels through a three-speed manual transmission.

Is the 1940 Dodge D14 equipped with Fluid Drive?

No. The 1940 D14 used a conventional single-plate dry clutch and manual gearbox. Dodge made Fluid Drive available in the following 1941 D19 series.

What is the difference between the D14 DeLuxe and Special?

Both trims shared the same basic chassis and 217.8-cubic-inch engine. The Special added higher-grade upholstery and exterior or convenience trim, although the exact combination should be confirmed by body style and factory literature because many surviving cars have exchanged parts.

How can I identify an authentic D14?

Start with the vehicle serial-number plate, then compare the title, body tag, engine stamp, body style, and assembly details with factory references. Do not treat the engine number as a modern matching VIN, and do not rely on a D14-style grille alone because front sheet metal can be swapped.

What are the most serious problems on a 1940 Dodge D14?

Structural rust, missing trim, cooling-system sediment, a damaged water-distribution tube, freeze-cracked castings, worn brake hydraulics, and loose steering components are the principal concerns. Station wagons add potentially extensive structural-wood deterioration.

Are restoration parts available for the Dodge D14?

Many flathead-six, ignition, brake, bearing, gasket, and clutch parts are available from specialist suppliers. Model-specific brightwork, dashboard pieces, body hardware, convertible components, and station-wagon wood are much harder to replace and often must be repaired or reproduced.

What makes a D14 most collectible?

Rare body styles attract the strongest attention, especially correctly restored convertibles and wood-bodied station wagons. Across all body styles, collectors value documented identity, complete trim, a proper flathead-six drivetrain, sound structure, correct materials, and the absence of irreversible modification.

Collector Takeaway

The D14 deserves preservation because it records Dodge's last Luxury Liner formula before Fluid Drive altered the marque's passenger-car experience. Its 218 flathead six, column-shifted three-speed, independent front suspension, and hydraulic drums form a coherent prewar package, simple enough to service yet advanced enough to use on secondary roads without turning every journey into an exercise in mechanical archaeology.

A four-door D14 should not be judged merely as the cheaper alternative to a coupe or woodie. The sedans are the cars that best explain Dodge's 1940 business: durable family transport with a modernized chassis and a drivetrain designed to pull cleanly rather than rev hard. Preserve the serial identity, cooling system, trim, and original body structure, and the D14 delivers something increasingly scarce, an honest account of how an American prewar car was engineered to work.
