The Honda Accord Inspire CB5, specifically the AG-i 2.0 variant, represents a significant step in Honda’s expansion into the upscale Japanese domestic market (JDM) sedan segment during the late 1980s and early 1990s. Produced from October 1989 to December 1991, the CB5 Inspire was positioned as a more luxurious and spacious alternative to the contemporary Honda Accord, sharing its platform but offering a more refined experience. The AG-i 2.0, with its 160 horsepower engine, occupied a mid-range position within the Inspire lineup, offering a balance between performance and fuel efficiency. It was a key model in establishing Honda’s presence in a market traditionally dominated by Toyota and Nissan.

Powertrain & Engine Architecture
The heart of the AG-i 2.0 Inspire is the G20A engine, a 1.996-liter inline five-cylinder gasoline engine. This engine was a relatively advanced design for its time, featuring multi-port fuel injection and a single overhead camshaft (SOHC) valvetrain. The G20A produced 160 horsepower at 6700 rpm and 186 Nm (137.19 lb-ft) of torque at 4000 rpm. The engine’s longitudinal mounting allowed for a front-wheel-drive configuration, a common layout for Honda vehicles of this era. The five-speed manual transmission was standard, providing drivers with direct control over the engine’s power. The G20A engine was known for its smooth operation and relatively good fuel economy for its displacement and power output.
Driving Characteristics
The AG-i 2.0 Inspire offered a comfortable and refined driving experience. The 160 hp engine provided adequate power for everyday driving and highway cruising, although it wasn’t particularly sporty. The five-speed manual transmission allowed for precise gear changes, and the engine’s torque curve provided good responsiveness. Compared to lower-powered Inspire variants, the AG-i 2.0 offered noticeably quicker acceleration and a more confident feel when overtaking. However, it didn’t possess the outright performance of some of its competitors, such as the Toyota Chaser or Nissan Skyline. The Inspire’s suspension, tuned for comfort, absorbed bumps and imperfections in the road well, providing a smooth ride.
Equipment & Trim Levels
The AG-i 2.0 Inspire came standard with a range of features designed to enhance comfort and convenience. These included power windows, power locks, air conditioning, and a basic audio system. The interior was typically finished with cloth upholstery, although leather options were available. Higher trim levels offered additional features such as a sunroof, upgraded audio system, and woodgrain interior trim. The AG-i 2.0 was positioned as a mid-range trim, offering a good balance of features and affordability. It was aimed at buyers who wanted a comfortable and well-equipped sedan without the expense of the top-of-the-line models.
Chassis & Braking
The Inspire CB5 utilized a double wishbone suspension system at both the front and rear, providing a comfortable ride and stable handling. The front brakes were ventilated discs, offering good stopping power, while the rear brakes were solid discs. Anti-lock braking system (ABS) was standard, enhancing safety by preventing wheel lockup during hard braking. The steering was a rack-and-pinion system with hydraulic power assistance, providing precise and effortless steering control. The tires were typically 195/65 R14, offering a good balance of grip and ride comfort.
Market Reception & Comparison
The Honda Accord Inspire CB5 AG-i 2.0 was generally well-received by Japanese automotive critics. It was praised for its comfortable ride, spacious interior, and refined engine. However, some critics noted that its performance wasn’t as exciting as some of its competitors. Compared to the base Inspire models with smaller engines, the AG-i 2.0 offered a significant improvement in performance. It also offered better fuel economy than the higher-powered variants. In terms of reliability, the G20A engine proved to be a durable and dependable unit, although regular maintenance was essential to ensure its longevity.
Legacy
The Honda Accord Inspire CB5 AG-i 2.0 remains a popular choice among JDM enthusiasts today. Its combination of comfort, reliability, and relatively affordable price makes it an attractive option in the used car market. The G20A engine is known for its durability, and parts availability is generally good. While not a high-performance vehicle, the AG-i 2.0 Inspire offers a unique and enjoyable driving experience, representing a significant chapter in Honda’s history of producing quality and innovative automobiles. The CB5 Inspire helped solidify Honda’s reputation as a manufacturer of reliable and well-engineered vehicles, paving the way for future success in the Japanese and international markets.
