The Audi Coupe (B2), produced between 1980 and 1988, marked a significant evolution for Audi in the realm of sporty, yet practical coupes. The 2.2i CAT Automatic variant, manufactured from 1985 to 1987, occupied a middle ground within the B2 Coupe lineup, balancing performance and ease of use. This model, identified by its catalytic converter (“CAT”) designation, targeted buyers seeking a comfortable and refined grand tourer, rather than the outright performance of the five-cylinder versions. It was positioned above the base 1.8-liter models and below the more potent 2.3-liter versions, making it a popular choice for those prioritizing a smooth driving experience.

Powertrain & Engine Architecture
The heart of the 2.2i CAT Automatic was Audi’s KX inline five-cylinder engine. This engine, a hallmark of Audi’s engineering prowess during the 1980s, displaced 2,226 cubic centimeters (135.84 cubic inches). It featured a single overhead camshaft (OHC) operating two valves per cylinder. The engine utilized Bosch multi-port fuel injection, a significant advancement over earlier carbureted systems, contributing to improved fuel efficiency and smoother power delivery. The catalytic converter, denoted by the “CAT” in the model name, was a crucial component in reducing harmful emissions, meeting increasingly stringent environmental regulations. The engine produced 115 horsepower at 5,500 rpm and 165 Nm (121.7 lb-ft) of torque at 2,500 rpm.
Paired with the engine was a three-speed automatic transmission. While not offering the driver engagement of a manual gearbox, this transmission prioritized comfort and ease of driving. The automatic transmission was chosen to appeal to a broader audience, particularly those who preferred a more relaxed driving experience. The transmission’s gear ratios were optimized for smooth acceleration and efficient cruising, though it didn’t provide the same level of responsiveness as the five-speed manual available on other B2 Coupe models.
Driving Characteristics
The 2.2i CAT Automatic Coupe offered a comfortable and refined driving experience. Acceleration from 0 to 60 mph took approximately 11.1 seconds, and it could reach a top speed of 113.71 mph. While these figures weren’t particularly impressive compared to the more powerful variants, the 2.2i provided adequate performance for everyday driving and long-distance touring. The automatic transmission, while smooth, did result in some power loss compared to the manual versions. The engine’s torque curve was relatively flat, providing decent pulling power at lower speeds, making it suitable for navigating city streets and climbing hills. However, the three-speed automatic limited the engine’s ability to rev freely, impacting overall responsiveness.
Equipment & Trim Levels
The 2.2i CAT Automatic typically came equipped with a reasonable level of standard features. These included power steering, central locking, and a basic stereo system. Interior upholstery was typically cloth, with options for leather available at an extra cost. The dashboard layout was functional and straightforward, with clearly marked gauges and controls. Optional extras included sunroofs, upgraded audio systems, and alloy wheels. The trim level generally fell in the mid-range of the B2 Coupe lineup, offering a step up in comfort and features compared to the base models, but lacking the luxury appointments of the 2.3-liter variants.
Chassis & Braking
The B2 Coupe featured a front-wheel-drive layout with independent suspension at the front and a torsion beam rear suspension. The 2.2i Automatic variant utilized ventilated disc brakes at the front and solid disc brakes at the rear, providing adequate stopping power for its weight and performance. The suspension was tuned for comfort, offering a relatively smooth ride, although it wasn’t as sporty as the suspension found on the higher-performance models. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The 2.2i CAT Automatic Coupe was generally well-received by automotive critics as a comfortable and practical grand tourer. It was praised for its smooth engine, comfortable ride, and reasonable fuel economy. However, it was often criticized for its lack of outright performance compared to the five-cylinder models. Compared to the 1.8-liter versions, the 2.2i offered a noticeable improvement in power and refinement. Against the 2.3-liter models, it represented a more affordable option, albeit with less performance. Fuel economy was respectable for the time, averaging around 25-30 mpg on the highway.
Legacy
The Audi Coupe B2, including the 2.2i CAT Automatic variant, remains a popular classic car among enthusiasts. The KX engine, while not the most powerful in the lineup, is known for its reliability and relatively straightforward maintenance. Parts availability is generally good, although some specific components may be becoming increasingly difficult to find. Today, these cars are appreciated for their distinctive styling, comfortable driving experience, and historical significance as a pioneering example of Audi’s engineering excellence. The 2.2i CAT Automatic, in particular, represents a sweet spot in the B2 Coupe range, offering a blend of practicality, comfort, and affordability that continues to appeal to collectors and enthusiasts alike.
