The Audi Coupe (B3), produced between 1988 and 1991, represented a significant evolution in Audi’s coupe design. The 2.3 E 20V quattro variant, manufactured from 1990 to 1991, was a performance-oriented model positioned near the top of the B3 Coupe range. It combined a potent five-cylinder engine with Audi’s renowned quattro all-wheel-drive system, offering a compelling blend of performance and all-weather capability. This model sat within the broader B3 chassis family (internally designated 89/8B), sharing its platform with the Audi 80 and 90 sedans.

Powertrain & Engine Architecture
The heart of the 2.3 E 20V quattro was the 7A engine, a 2.3-liter inline five-cylinder powerplant. This engine was a significant departure from the more common four-cylinder engines found in other B3 Coupe variants. The 7A featured a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder – hence the “20V” designation – and multi-port fuel injection. This configuration allowed for excellent breathing and a broad powerband. The engine produced 167 horsepower at 6000 rpm and 216 Nm (159.31 lb-ft) of torque at 4500 rpm. The longitudinal engine layout, coupled with the quattro all-wheel-drive system, provided balanced weight distribution and enhanced traction. The five-speed manual transmission was the only gearbox option for this specific model, prioritizing driver engagement and performance.
Driving Characteristics
The 2.3 E 20V quattro offered a noticeably more engaging driving experience than its lower-powered siblings. The five-cylinder engine delivered strong acceleration, achieving 0-60 mph in approximately 8 seconds and a top speed of 136.7 mph. The quattro system provided exceptional grip, particularly in adverse weather conditions, inspiring confidence during spirited driving. The five-speed manual transmission allowed for precise control over the engine’s power. While not a dedicated sports car, the 2.3 E 20V quattro offered a refined and capable driving experience, blending performance with practicality.
Equipment & Trim Levels
The 2.3 E 20V quattro was generally well-equipped, reflecting its position as a premium variant. Standard features typically included power windows, central locking, and an upgraded audio system. Interior upholstery was usually a combination of cloth and leather. Optional extras included a sunroof, heated front seats, and upgraded alloy wheels. The dashboard layout was typical of early 1990s Audis, characterized by a functional and understated design. The instrument cluster featured a comprehensive array of gauges, including a tachometer, speedometer, fuel gauge, and coolant temperature gauge.
Chassis & Braking
The B3 Coupe chassis featured independent suspension all around, with wishbone suspension at the front and a double wishbone setup at the rear. This configuration provided a comfortable ride and good handling characteristics. The 2.3 E 20V quattro was equipped with ventilated disc brakes at the front and solid disc brakes at the rear. An anti-lock braking system (ABS) was standard, enhancing braking performance and safety. The steering was a rack-and-pinion system with hydraulic power assistance, providing precise and responsive steering feel.
Market Reception & Comparison
The 2.3 E 20V quattro was generally well-received by automotive critics, who praised its performance, handling, and all-weather capability. It was often compared to other performance coupes of the era, such as the BMW 3 Series Coupe and the Mercedes-Benz 190E Coupe. Compared to the base 1.8-liter and 2.0-liter Coupe models, the 2.3 E 20V quattro offered a significant performance upgrade, but at a higher price point. Fuel economy was reasonable for a performance car of its time, averaging around 25.6 US mpg in combined driving. The 2.3 E 20V quattro was considered a more refined and capable alternative to the more basic Coupe models.
Legacy
The Audi Coupe B3, and particularly the 2.3 E 20V quattro variant, holds a respected place among Audi enthusiasts. The 7A engine is known for its durability and tunability, and well-maintained examples are still sought after today. While not immune to age-related issues, the powertrain is generally considered reliable. The quattro all-wheel-drive system remains a key selling point, particularly in regions with inclement weather. In the used car market, the 2.3 E 20V quattro commands a premium over the lower-powered Coupe models, reflecting its performance and rarity. It represents a significant chapter in Audi’s history, showcasing the brand’s commitment to engineering excellence and driving pleasure.
