The 1959 Chevy Impala Sport Coupe stands as a defining monument of mid-century American automotive design. Distinguished by its flat, gull-wing rear fins and cat-eye taillights, this model broke away from conservative styling to capture the optimism of the jet age. Originally introduced as a top-tier trim within the Chevrolet lineup for 1958, the Impala became its own distinct series for 1959, achieving immediate cultural permanence.
Beneath its sweeping roofline and expansive glass area, the car offered buyers a massive spectrum of powertrain configurations, ranging from economical inline-sixes to high-output 348-cubic-inch V8 blocks. Whether you're researching its mechanical specifications, structural design features, or current collector market standing, this guide breaks down why the '59 Sport Coupe remains a high-water mark for General Motors.
Evolution of the 1959 Design
General Motors design chief Harley Earl and his team took a massive risk for the 1959 model year. While competitors like Chrysler and Cadillac pursued towering vertical fins, Chevrolet went wide and flat.
The Sport Coupe featured a distinct low-slung stance on a 119-inch wheelbase, stretching over 210 inches in total length. Its roofline featured thin pillars that created a light, airy canopy over the interior cabin, contrasting sharply with the heavy, slab-sided appearance of earlier decade designs.
The most celebrated visual elements include:
- The Bat-Wing Fins: Horizontal tailfins that stretched outward rather than upward, giving the illusion of motion even when parked.
- Cat-Eye Taillights: Dual teardrop-shaped rear lamps recessed into the rear fascia, replacing traditional round lenses.
- Contessed Front End: A wide grille housing dual quad headlights that pushed outward to emphasize the car's broad stance.
Engine Options and Mechanical Performance
Chevrolet didn't just redesign the sheet metal; they engineered a diverse mechanical ecosystem. Buyers could customize their driving experience from a mild cruiser to a strip-ready performer.
The baseline engine was a 235.5-cubic-inch "Blue Flame" inline-six producing 135 horsepower. However, most buyers opted for the engine bay upgrades. The standard V8 offering was the 283-cubic-inch Turbo-Fire, which generated 185 horsepower, scaling up through various multi-carburetor and mechanically fuel-injected configurations reaching 290 horsepower.
For maximum performance, the heavy-duty 348-cubic-inch "W-block" V8 engine became the powerhouse of choice. Available with triple two-barrel carburetors (often called Tri-Power), the 348 pushed output anywhere from 250 horsepower up to 315 horsepower in standard factory high-performance tune, and even higher in specialized dealer offerings.
Transmission pairings matched this variety. Drivers could select a traditional three-speed manual, a four-speed manual (the first year full-size Chevys offered a factory four-speed), an overdrive unit, or automatic options like the two-speed Powerglide and the complex Turboglide.
Interior Comfort and Practicality
The cabin of the Sport Coupe matched its radical exterior. It featured a dual-cowl dashboard layout, deep-dish steering wheel, and upgraded upholstery patterns exclusive to the Impala series.
Despite the sloping fastback roof profile, passenger space remained generous. The X-member frame, introduced a year prior, allowed the floorpan to drop lower, creating extra legroom for six occupants across two wide bench seats. Factory options included power steering, power brakes, a transistorized radio, and even "Level Air" suspension—though the air system proved troublesome for early owners and many were later converted to standard coil springs.

Common Restoration and Ownership Challenges
Restoring a 1959 Chevy Impala Sport Coupe requires patience due to unique one-year-only body panels and trim. Because 1959 sheet metal was completely unique to that single model year, finding clean donor fenders, rear quarter panels, or intact stainless steel trim can challenge restorers.
- Rust-Prone Areas: Pay close attention to the rear wheel arches, floor pans, trunk wells, and the heavy X-frame channels where moisture collects.
- Trim Availability: While mechanical parts for the 283 and 348 V8 engines are readily available through aftermarket suppliers, brightwork and original interior fabrics demand specialty sourcing.
- Suspension Tuning: Keeping the heavy front end aligned properly with manual or early power steering boxes requires fresh bushings and correct geometry checks.

Frequently Asked Questions
How many 1959 Chevy Impala Sport Coupes were built?
Chevrolet produced hundreds of thousands of full-size cars in 1959, with the Impala series capturing a massive share of total volume. The Sport Coupe hardtop body style stands out as one of the most popular configurations of that production run.
What is the difference between a 1959 Impala and a Bel Air?
While the 1958 model year integrated the Impala as a trim level under the Bel Air family, 1959 elevated the Impala to its own standalone top-tier series. Impalas featured upgraded interior appointments, distinctive side chrome molding, triple rear taillights per side, and more ornate exterior badging.
What was the original base price of the car?
When new in 1959, the Impala Sport Coupe retailed for roughly $2,598 before adding optional extras like V8 engines, automatic transmissions, or radios.
Which engine is most desirable for collectors today?
Cars equipped with the factory 348-cubic-inch V8—particularly Tri-Power setups or rare fuel-injected 283 variants—command the highest market values among classic car collectors and enthusiasts.
