The Opel Tigra B TwinTop, produced from October 2004 to June 2009, represented a significant evolution for the Tigra nameplate. It transitioned from a compact 2+2 coupe to a stylish two-seat coupe-cabriolet, specifically designed to appeal to the European market’s demand for affordable, compact convertibles featuring the security and refinement of a retractable hardtop. While Opel, a German brand within the General Motors family, did not offer the Tigra B TwinTop in the United States, it found considerable success in Europe where this type of vehicle was highly sought after. This particular variant, the 1.4i 16V ECOTEC (90 Hp) Automatic, balanced efficiency with accessible performance, making it suitable for both urban commuting and leisure driving.
Engine & Performance of the Opel Tigra B TwinTop
The Opel Tigra B TwinTop 1.4i 16V ECOTEC was powered by a naturally aspirated 1.4-liter (1364 cm³) inline four-cylinder engine, internally designated as the Z14XEP. This ECOTEC engine, a key component of Opel’s commitment to efficiency and reduced emissions, featured a dual overhead camshaft (DOHC) valvetrain and four valves per cylinder, optimizing airflow and combustion. It produced 90 horsepower at 5600 rpm, providing adequate power for a vehicle of its size and intended use. Peak torque output was 92.2 lb.-ft. (125 Nm) at 4000 rpm, delivering a smooth and usable powerband for everyday driving conditions.
The powertrain was paired with a 5-speed automatic transmission, prioritizing ease of use and comfort, especially in congested urban areas. Performance figures reflected the Tigra’s character as a cruiser rather than a sports car. Acceleration from 0 to 60 mph was achieved in approximately 12.7 seconds (0-100 km/h in 13.4 seconds), with a maximum speed of 110.6 mph (178 km/h). These figures were competitive within its segment, aligning with the expectations of buyers seeking a stylish convertible that was also economical to operate.
Fuel economy was a significant strength of this variant, thanks to the ECOTEC engine and the vehicle’s relatively light curb weight of 2722.71 lbs. (1235 kg). Combined fuel consumption was rated at an impressive 39.2 US mpg (6 liters per 100 km), with extra-urban figures reaching 48 US mpg (4.9 liters per 100 km). This efficiency, combined with an 11.89 US gallon (45 liter) fuel tank, provided a practical range for weekend trips, making the Tigra TwinTop an attractive option for cost-conscious consumers.
Design and Features: The Opel Tigra B TwinTop Aesthetic
The most defining characteristic of the Opel Tigra B TwinTop was its innovative coupe-cabriolet body style. Unlike its fixed-roof predecessor, the B generation featured an electrically operated two-piece retractable hardtop. This allowed the car to transform from a sleek coupe into an open-air roadster with the push of a button, offering the benefits of both a secure hardtop for inclement weather or urban parking and the enjoyment of open-top driving when conditions allowed. The transformation process took around 18 seconds, a competitive time for vehicles of that era.
Designed as a strict two-seater, the Tigra TwinTop offered a driver-focused interior. Its compact dimensions—154.37 inches (3921 mm) in length, 66.34 inches (1685 mm) in width, and 53.7 inches (1364 mm) in height—made it highly maneuverable in tight European city streets and easy to park. The wheelbase measured 98.07 inches (2491 mm), contributing to its agile handling.
Despite its small size, the Tigra TwinTop maximized cargo space. With the roof up, trunk capacity was a generous 8.83 cubic feet (250 liters), expanding to an impressive 15.54 cubic feet (440 liters) when the roof was stowed. This class-leading trunk volume, achieved by positioning the roof in a dedicated compartment above the rear axle, made the Tigra surprisingly practical for a two-seat convertible, capable of accommodating luggage for a weekend getaway.
From a safety and handling perspective, the Tigra B TwinTop utilized a front-wheel-drive layout, common for compact European vehicles, providing predictable handling characteristics. The suspension system featured a spring strut design at the front and coil springs at the rear, tuned for a comfortable yet responsive ride. Braking was handled by ventilated discs at the front and solid discs at the rear, complemented by an Anti-lock Braking System (ABS) as standard equipment, enhancing stopping power and control. Steering was managed by a rack and pinion system, offering direct feedback to the driver. The car rode on 185/60 R15 tires mounted on 6J x 15-inch wheel rims, a sensible setup for its power and weight.

Legacy and Market Impact of the Opel Tigra B TwinTop
The Opel Tigra B TwinTop established a unique position in the European automotive market during its production. It entered a segment experiencing growing demand for compact, affordable coupe-cabriolets, a trend pioneered by vehicles like the Peugeot 206 CC. The Tigra TwinTop’s main competitors included the Peugeot 206 CC, the Nissan Micra C+C, and later, the Mitsubishi Colt CZC.
Opel’s decision to transform the Tigra from a 2+2 coupe into a dedicated two-seat roadster with a retractable hardtop was a strategic move to capitalize on this emerging segment. The car was generally well-received for its innovative roof mechanism, stylish design, and respectable fuel economy, particularly with the 1.4-liter ECOTEC engine. It provided an accessible entry point into convertible ownership, combining the appeal of open-top motoring with the practicality and security of a fixed roof.
Its reputation was built on offering a fun, youthful driving experience without a high price tag. While not a performance-oriented vehicle, the 1.4i 16V ECOTEC Automatic variant was praised for its ease of driving in urban environments and its comfortable ride on longer journeys. The generous trunk space, uncommon in small convertibles, further enhanced its appeal as a practical daily driver or weekend vehicle.
However, like many niche vehicles, the Tigra B TwinTop’s market run was limited. The segment for small coupe-cabriolets eventually declined as consumer preferences shifted towards crossovers and SUVs, and the cost of developing complex retractable hardtop mechanisms for compact cars became less feasible. Production of the Opel Tigra B TwinTop ended in June 2009, making it a relatively short-lived but memorable part of Opel’s history. Today, the Tigra TwinTop remains a popular choice on the used car market in Europe for those seeking an affordable, stylish, and practical convertible, embodying the spirit of accessible open-top motoring from the mid-2000s. Its legacy is one of clever engineering and successful adaptation to a specific market trend, demonstrating that even a small car can deliver significant lifestyle appeal.
