The Mazda Clef (GE) 2.5 i V6 24V, produced between 1992 and 1996, represented a somewhat niche offering from Mazda during a period of evolving sedan designs. Positioned as a more upscale and sporty alternative within the Japanese domestic market (JDM), the Clef aimed to blend comfort with a degree of performance. It was based on Mazda’s GE platform, sharing some underpinnings with other models of the era, but distinguished itself through its unique styling and available engine options. The 2.5-liter V6 variant, producing 200 horsepower, was a flagship trim, offering a significant power upgrade over the base models and targeting buyers seeking a more engaging driving experience. While not a massive sales success, the Clef holds a place as an interesting example of 1990s Japanese automotive design and engineering.

Powertrain & Engine Architecture
The heart of the Clef 2.5 i V6 was the JE engine, a 2.5-liter (2497 cc) naturally aspirated V6. This engine utilized a 90-degree V-angle, contributing to a smoother power delivery and reduced vibrations. It featured a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for increased power output. The engine employed multi-port fuel injection, delivering fuel directly to each intake port for precise fuel metering and improved combustion efficiency. The 9.2:1 compression ratio was a compromise between performance and reliability, allowing the engine to run on readily available gasoline grades. Paired with this engine was a four-speed automatic transmission. This transmission, while providing convenience, was a relatively conventional design for the early 1990s, prioritizing smooth shifts over outright performance. It was geared towards comfortable cruising rather than aggressive acceleration.
Driving Characteristics
The 200 horsepower and 165 lb-ft of torque offered by the 2.5-liter V6 provided a noticeable step up in performance compared to the lower-displacement engines available in the Clef lineup. While not a sports car, the V6-powered Clef offered brisk acceleration and comfortable highway cruising. The automatic transmission, however, did detract somewhat from the driving experience. Shifts were smooth but not particularly quick, and the transmission’s programming prioritized fuel economy over responsiveness. Compared to a manual transmission equipped Clef, the automatic version felt less engaging and slightly slower in acceleration. The front-wheel-drive layout also contributed to a degree of torque steer under hard acceleration.
Equipment & Trim Levels
The 2.5 i V6 trim of the Mazda Clef was generally well-equipped for its time. Standard features typically included power windows, power locks, air conditioning, and a basic audio system. Interior upholstery was usually cloth, though leather options were sometimes available as an upgrade. The dashboard layout was functional and straightforward, with clearly marked gauges and controls. Optional extras could include a sunroof, upgraded audio systems, and alloy wheels. The overall interior ambiance aimed for a comfortable and refined experience, reflecting the Clef’s positioning as a more premium offering.
Chassis & Braking
The Clef utilized a relatively conventional chassis design for a front-wheel-drive sedan. Front suspension consisted of MacPherson struts, while the rear employed a multi-link setup. This configuration aimed to balance ride comfort with handling stability. Braking duties were handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) was included as standard equipment, enhancing safety by preventing wheel lockup during hard braking. The steering system was a rack-and-pinion setup with hydraulic power assistance, providing light and precise steering feel.
Market Reception & Comparison
The Mazda Clef, particularly the 2.5 i V6 variant, received mixed reviews from automotive critics. While the engine was praised for its smooth power delivery and refinement, the overall design of the Clef was sometimes criticized as being somewhat bland and lacking in visual appeal. The automatic transmission was also a point of contention, with some reviewers noting its lack of responsiveness. Compared to other sedans in its class, such as the Toyota Camry or Honda Accord, the Clef offered a more distinctive driving experience but lacked the same level of brand recognition and resale value. Fuel economy was reasonable for a V6 engine of that era, but not exceptional.
Legacy
Today, the Mazda Clef 2.5 i V6 24V is a relatively rare sight, particularly outside of Japan. While not known for any major reliability issues, the age of these vehicles means that maintenance and parts availability can be a challenge. The JE V6 engine is generally considered to be a durable and reliable unit, provided it has been properly maintained. The automatic transmission, however, may be more prone to wear and tear. In the used car market, the Clef 2.5 i V6 commands a modest premium over the lower-displacement models, appealing to enthusiasts seeking a unique and relatively affordable classic Japanese sedan.
