10 Underrated 1980s Supercoupes That Deserve More Respect

The 1980s gave rise to a golden era of supercoupes. These sleek machines packed a serious punch under the hood. They were described as turbocharged beasts and grand tourers with racing DNA. These icons blended flash and futuristic features that people loved experiencing. Let’s revisit the coupes that truly defined cool in the ’80s and check how many you recognize.
Porsche 928S (1983)

Powered by a 4.7-liter V8 producing 295 horsepower, the 928S marked Porsche’s bold pivot toward grand touring. With the engine up front and a rear-mounted transaxle, it achieved nearly perfect weight distribution. Inside, it also featured a futuristic digital instrument panel and comforts rare in performance cars of its era.
Buick GNX (1987)

The GNX took the already ferocious Grand National to a whole new level. Under the hood was a turbocharged 3.8-liter V6 rated at 276 hp and 359 lb-ft of torque, though insiders suggest the actual numbers were even higher. Modified by McLaren ASC, the GNX boasted upgraded suspension and drivetrain components.
BMW M635CSi (1985)

Also known as the M6 in the U.S., the European-spec M635CSi was powered by the same M88/3 3.4-liter inline-six found in the legendary M1, delivering 286 hp. The 5-speed manual and limited-slip differential offered precise control, while BBS wheels and shark-nose styling gave it unmatched presence. It was every bit the luxury coupe with motorsport DNA.
Ferrari 412 (1985)

Who said Ferraris can’t be practical? The 1985 Ferrari 412 begged to differ—with four seats, leather everywhere, and even ABS. Underneath the understated exterior sat a 4.9-liter V12, ready to roar when prompted. Designed for drivers who valued refinement as much as horsepower.
Aston Martin V8 Vantage Zagato (1986–1989)

A collaboration between Aston Martin and Zagato resulted in this aggressively styled, ultra-rare supercoupe. Its 5.3-liter V8 churned out 438 hp and launched the car from 0 to 60 in just over 5 seconds. With a shortened wheelbase and only 52 units produced, this hand-built icon is one of Aston Martin’s most coveted.
Renault Alpine GTA V6 Turbo (1987)

The Alpine GTA V6 Turbo was France’s answer to the era’s sports coupes. It had features like a mid-mounted 2.4-liter turbo V6 producing 200 hp and a lightweight fiberglass body that prioritized agility and performance. Its streamlined, aerodynamic profile also made it a unique sight on European roads, and it carried Alpine’s racing pedigree proudly.
Chevrolet Monte Carlo SS (1984)

Created to meet NASCAR homologation requirements, the Monte Carlo SS featured a high-output 5.0-liter V8 delivering 180 hp. That sharp nose and spoiler? Borrowed straight from the racetrack playbook. Affordable and durable, the SS became a symbol of accessible American performance and street presence.
Volvo 780 Bertone Coupe (1986)

The 1986 Volvo 780 was no ordinary coupe. Styled and hand-built by the Italian firm Bertone, it fused Scandinavian reliability with European flair. A naturally aspirated 2.8-liter V6 powered the rear wheels, and independent rear suspension gave it composed handling. Limited to just 8,500 units, the 780 remains a refined rarity.
Nissan Leopard Ultima (1989)

In Japan, it was the Leopard Ultima. In the U.S., it quietly slipped in as the Infiniti M30. This 1989 coupe packed a 3.0-liter V6 with 255 horsepower and threw in some ’80s magic—a digital dash, plush interiors, and top-notch sound. A bubble-era icon that Americans barely noticed.
Mazda RX-7 Turbo II (1987)

A true Japanese performance icon, the second-generation RX-7 Turbo II packed a 1.3-liter turbocharged rotary engine producing 182 hp. Thanks to its lightweight construction and near-perfect 50:50 weight distribution, it delivered razor-sharp handling and a high-revving, distinct powerband.
