The Opel Signum 3.2i V6 24V ECOTEC (211 Hp) Automatic: An Executive Hatchback Experiment

The Opel Signum, specifically the 3.2i V6 24V ECOTEC (211 Hp) Automatic variant, represents a fascinating and somewhat unconventional chapter in the history of European automotive design. Launched in May 2003 and produced until June 2005, the Signum was Opel’s ambitious attempt to carve out a unique niche in the competitive European D-segment (mid-size executive car market). Rather than a traditional sedan or wagon, Opel opted for a distinctive five-door “executive hatchback” or “liftback” body style, emphasizing interior versatility and rear passenger comfort.

Based on the extended platform of the Opel Vectra C station wagon, the Signum aimed to combine the practicality of a hatchback with the spaciousness and premium feel typically associated with larger, more upscale vehicles. The 3.2-liter V6 ECOTEC engine, paired with a smooth automatic transmission, positioned this particular variant as the flagship model, offering robust performance for discerning drivers who valued both power and innovative design.

Engine & Performance: Powering the Opel Signum 3.2i V6 24V ECOTEC (211 Hp) Automatic

At the heart of the top-tier Opel Signum was its potent 3.2-liter (3175 cm³, 193.75 cu. in.) naturally aspirated V6 ECOTEC engine, designated as the Z32SE. This sophisticated powerplant was designed to deliver a blend of performance and relative refinement for its era. With a DOHC (Double Overhead Camshaft) valvetrain and four valves per cylinder, the engine produced a healthy 211 horsepower at 6200 rpm. Torque output stood at 221.27 lb.-ft. (300 Nm) available at 4000 rpm, providing ample pulling power across a broad rev range.

Power was delivered to the front wheels through a 5-speed automatic transmission, chosen for its smooth shifts and ease of driving, aligning with the Signum’s executive aspirations. This powertrain combination allowed the 1610 kg (3549.44 lbs.) vehicle to accelerate from 0 to 60 mph in a respectable 8.1 seconds, with a maximum speed of 146.02 mph (235 km/h). While not a sports car, the V6 Signum offered brisk performance for highway cruising and confident overtaking maneuvers.

Despite its larger engine, Opel’s ECOTEC (Emissions COntrol TEChnology) philosophy aimed for a balance of power and efficiency. The combined fuel economy for the 3.2i V6 was rated at 10.7 liters per 100 km, which translates to approximately 22 US mpg. Urban consumption was naturally higher at 15.7 l/100 km (15 US mpg), while extra-urban driving saw a more economical 7.8 l/100 km (30.2 US mpg). These figures were competitive for a V6-powered vehicle of its size and class in the early 2000s.

Design & Features: A Focus on Versatility and Comfort

The Opel Signum’s most distinctive characteristic was its unique “Hatchback” body type, which blurred the lines between a traditional sedan, a wagon, and a luxury liftback. Measuring 182.52 inches (4636 mm) in length, 70.79 inches (1798 mm) in width, and 57.72 inches (1466 mm) in height, the Signum was substantial. Its extended wheelbase of 111.42 inches (2830 mm) was a direct result of its platform sharing with the Vectra C wagon, a key enabler for its primary design goal: maximizing rear passenger space and flexibility.

Inside, the Signum featured a sophisticated and highly adaptable cabin. The rear seating area was particularly innovative, offering two individual seats (though a central jump seat was sometimes available) that could slide, recline, and even be folded down independently. This “FlexSpace” system provided exceptional legroom for rear occupants, akin to what one might find in a much larger executive sedan, along with modular cargo capabilities. The trunk space ranged from a decent 12.89 cu. ft. (365 l) with all seats up, expanding significantly to 49.79 cu. ft. (1410 l) with the rear seats folded, making it highly practical for various needs.

Standard features for a vehicle of its segment in the early 2000s included an advanced climate control system, a comprehensive infotainment setup (often with a color display), and various power amenities. Safety was addressed with features like ABS (Anti-lock Braking System) as standard, along with a suite of airbags. The car’s driving dynamics were managed by a front-wheel-drive architecture, coil spring suspension at both front and rear, and ventilated disc brakes all around, ensuring a comfortable and secure ride. Hydraulic power steering with a rack and pinion setup provided direct and responsive handling.

Legacy & Market Impact of the Opel Signum

The Opel Signum, particularly in its powerful 3.2i V6 24V ECOTEC (211 Hp) Automatic guise, represented a bold move by Opel to redefine the executive car segment in Europe. Its primary competitors were not just traditional sedans like the Volkswagen Passat, Ford Mondeo, or Peugeot 406, but also potentially more premium offerings from brands like Audi (A4) or BMW (3 Series), which often lacked the Signum’s emphasis on rear-passenger flexibility and cargo volume. However, this very uniqueness proved to be a double-edged sword.

While praised for its innovative FlexSpace interior, comfortable ride, and the strong performance of its V6 engine, the Signum struggled to find a significant market foothold. Its unconventional styling, which some found awkward, and its positioning between traditional segments confused many potential buyers. It was arguably too large and expensive to compete with mainstream family hatchbacks, yet its Opel badge and “hatchback” designation prevented it from being perceived as a true executive sedan alternative to more prestigious brands.

Despite Opel’s efforts to market it as a car for the “thinking driver” or those seeking practicality without sacrificing luxury, the Signum never achieved the sales success Opel had hoped for. Its production run was relatively short, ending in 2005 for the V6 model and the entire Signum line being discontinued in 2008. In retrospect, the Opel Signum is often viewed as an interesting but commercially unsuccessful experiment in automotive design. It showcased Opel’s willingness to innovate and challenge conventional segment definitions, providing a highly versatile and comfortable vehicle for its niche. Today, the Signum remains a curiosity, appreciated by a small segment of enthusiasts for its unique approach to passenger comfort and its robust V6 powertrain, standing as a testament to a period when manufacturers were more willing to explore unconventional body styles in the mainstream market.
