Powertrain & Engine Architecture
The heart of the CX 2400 GTi was the M23.622 engine, a 2.4-liter inline-four cylinder gasoline engine. This engine was a development of the earlier 2.2-liter unit, featuring a larger displacement to increase power and torque. It utilized a cast iron block and an aluminum cylinder head, a common configuration for engines of this era. The engine employed a multi-port fuel injection system, which improved fuel efficiency and responsiveness compared to earlier carbureted designs. The valvetrain consisted of two valves per cylinder, operated by a single overhead camshaft. The engine produced 130 horsepower at 5000 rpm and 201 Nm (148 lb-ft) of torque at 3750 rpm. The engine was transversely mounted, driving the front wheels. The CX 2400 GTi was equipped with a five-speed manual transmission, providing precise gear changes and allowing the driver to fully utilize the engine’s power band.
Driving Characteristics
The CX 2400 GTi offered a refined and comfortable driving experience. The 2.4-liter engine provided ample power for both city driving and highway cruising. Acceleration to 60 mph was achieved in approximately 9.8 seconds, and the car had a top speed of 118.68 mph. While not a sports car in the modern sense, the CX 2400 GTi offered a good balance of performance and comfort. The five-speed manual transmission allowed for precise control over the engine’s power delivery. The CX’s renowned hydropneumatic suspension system, a Citroën hallmark, provided an exceptionally smooth and controlled ride, absorbing bumps and imperfections in the road with ease. Compared to the lower-powered CX models, the 2400 GTi offered noticeably improved acceleration and responsiveness. It also felt more stable at higher speeds, making it a capable long-distance cruiser.
Equipment & Trim Levels
The 2400 GTi trim level was well-equipped for its time. Standard features included comfortable cloth upholstery, power-assisted steering, and front disc brakes. The interior was designed with a focus on ergonomics and practicality. Optional extras included leather upholstery, air conditioning, and a sunroof. The dashboard featured a comprehensive array of gauges, including a speedometer, tachometer, fuel gauge, and coolant temperature gauge. The CX 2400 GTi also featured Citroën’s distinctive steering wheel design, with a single spoke and various controls integrated into the hub.
Chassis & Braking
The CX featured an independent suspension system on all four wheels, utilizing Citroën’s innovative hydropneumatic technology. This system allowed the car to maintain a constant ride height regardless of load, and provided exceptional ride comfort and handling. The front suspension consisted of double wishbones, while the rear suspension utilized trailing arms. The CX 2400 GTi was equipped with ventilated disc brakes on the front wheels and disc brakes on the rear wheels, providing ample stopping power. The steering system was a rack-and-pinion type, offering precise and responsive steering feel.
Market Reception & Comparison
The Citroën CX 2400 GTi was generally well-received by automotive critics. It was praised for its comfortable ride, refined handling, and powerful engine. However, some critics noted that the car’s styling was somewhat polarizing, and that the hydropneumatic suspension system could be complex and expensive to maintain. Compared to other cars in its class, such as the Peugeot 505 and the BMW 5 Series, the CX 2400 GTi offered a unique combination of comfort, technology, and performance. Its fuel economy was comparable to other cars in its class, and its reliability was generally considered to be good, although the hydropneumatic suspension system required regular maintenance.
Legacy
The Citroën CX 2400 GTi remains a sought-after classic car today. Its innovative technology, distinctive styling, and comfortable ride have earned it a loyal following among enthusiasts. While the hydropneumatic suspension system can be challenging to maintain, the CX 2400 GTi offers a unique and rewarding driving experience. The M23.622 engine, when properly maintained, is known for its durability and reliability. Parts availability can be a concern, but a dedicated network of specialists and suppliers exists to support CX owners. The CX 2400 GTi represents a high point in Citroën’s engineering history, and a testament to the brand’s commitment to innovation and comfort.
