Mercury Turnpike Cruiser

The Turnpike Cruiser shared its 122-inch wheelbase, rear-wheel drive, body-on frame chassis with the Monterey and Montclair.[8] Front suspension was independent ball-joint with coil springs, the rear a live axle with leaf springs.[8] Brakes were 11-inch drummed all round.[8]

Edsel adopted a 124-inch wheelbase version of the chassis was for its 1958 model year Corsair and Citation premium model lines.

For 1957, the Turnpike Cruiser was fitted with a 368 cubic-inch, 290 hp V8.[9] Sharing its name with the car, the engine was offered as an option across the rest of the Mercury line. For 1958, two all-new "Marauder" engines were introduced: a 383 cubic-inch, 330 hp V8 was standard (and shared with the Montclair and Colony Park);[10] and a 430 cubic-inch, 360 hp (shared with the Park Lane).[10][11] An optional triple-two barrel carburetor "Super Marauder" version of the 430 V8 produced 400 hp.[10][12][13] Exclusive to Mercury, the Super Marauder was the first factory-produced engine with a 400 hp output, a response to the 375/390 hp 1957 Chrysler 300C.

All Turnpike Cruiser engines were paired with a 3-speed "Merc-O-Matic" automatic. For 1957, Mercury offered pushbutton transmission controls in response to the Chrysler TorqueFlite introduced in 1956. The Mercury control buttons initially offered five buttons and was called "Keyboard Control", with a long button on top labeled "Drive" and four smaller buttons below labeled "Brake", "Neutral Start" (which would allow the engine to start with the ignition key), "Hill Control", and "Reverse". Later versions, relabeled as "Multi-Drive" for 1958, separated the "Drive" button to "Performance" and "Cruising". A separate push/pull lever was included below the control buttons labeled "Park" which would lock out the control buttons until the Park button was pulled to release it. The control panel was installed to the left of the steering wheel. In 1959 the keyboard control was discontinued and replaced with a standard steering column gear selector lever.[1][14][15][16]

During its production, the Turnpike Cruiser was offered as a two-door and four-door hardtop. To serve as the pace car for the 1957 Indianapolis 500, a convertible was created (named the Convertible Cruiser), leading Mercury to offer a replica version for sale. It was offered in a single yellow (Sun Glitter) exterior color and fitted with the optional continental tire kit.

An unusual 1957 feature was an ornament mounted outside at the base of the rear window, which was relocated inside next to the rear window and would light up if the exterior lights were on.[1]

While sharing much of its body with the Montclair, the Turnpike Cruiser was distinguished by several exterior design features. Although not legalized across the entire United States until 1958, "Quadri-Beam" dual headlamps were fitted as standard equipment (the only 1957 Mercury to do so, as well as one of very few cars from that year to be equipped as such); for states that still mandated single headlights a standard setup was used. In place of contrasting paint, the scalloped tailfins were gold-anodized. Along with its retractable "Breezeway" rear window, the Turnpike Cruiser received a separate roofline, with a windshield curving into the roof;[21] the windshield was among the first to use tint to reduce solar glare.[14] As a consequence of the compound-curve design of the windshield, Mercury added rooftop ventilation intakes to the Turnpike Cruiser to cover a body seam, and unusually in a secondary function, each intake also housed a fake radio antenna, as the functional radio antenna was mounted on the passenger side front fender.[21] Air conditioning and power side windows were additional cost options.[22] For 1958, the Turnpike Cruiser adapted the styling changes of the Montclair and Monterey, shifting the grilles into the front bumper. The rear fascia saw multiple changes, as the gold-anodized trim was removed from the scalloped fins; "rocket-style" taillamps were added.[23] To distinguish the model line from the Montclair (and Park Lane), the Turnpike Cruiser was given gold trim for its badging (including the Mercury "M" grille badge).

The interior of the Turnpike Cruiser offered several features distinct from other Mercury sedans. To aid forward visibility, a flat-top deep-dish steering wheel was fitted (to match the curve of the instrument panel).[21][24] Alongside a tachometer ("to measure engine efficiency"[14]),[9] the instrument panel was fitted with a clock to calculate average speed and a trip odometer (effectively, a trip computer).[21] One of the first memory seats, "Seat-O-Matic" was programmable and moved down and back when the ignition was off.[21][25] While not equipped with cruise control, in 1958, the Turnpike Cruiser (alongside all Mercurys) was introduced with a programmable speed warning, setting off a warning if a preset speed was exceeded.[25]

The Turnpike Cruiser standardized several Mercury safety features, including a padded dashboard (and dashboard gauges[21]), a deep-dish flat-top steering wheel, and safety door locks; seatbelts were optional, alongside a safety harness for children.[21] Nearly 10 years before their introduction, the design of the taillamps performed as side marker lamps.[21]
