Honda S2000 AP1 vs AP2: A Comparison

Honda S2000 AP1 vs AP2: What Actually Changed and Why It Matters

Honda built the S2000 to mark its 50th anniversary in 1999, and the brief they handed their engineers was unambiguous: create a roadster that traces a direct line back to the S500, S600, and S800 of the 1960s, but arm it with late-1990s technology and genuine racing DNA. The result was a car that polarised opinion on the street and earned near-universal admiration on track. Over a ten-year production run, the S2000 split into two distinct variants — the AP1 (1999–2003) and the AP2 (2004–2009) — each with a different answer to the question of how a driver's car should behave. Understanding exactly what changed between them, and why Honda made those calls, tells you a great deal about both cars.

Production Timeline

AP1 (1999–2003): The Original Vision

The AP1 launched in 1999 and immediately established what the S2000 was about: a near-50/50 weight distribution, a chassis built around driver feedback, and an engine that rewarded commitment. Honda's engineering priorities were unmistakable — this was a car that demanded skill in exchange for an exceptional experience. Critical reception was strong, with reviewers noting that despite its performance credentials, the AP1 remained surprisingly manageable as daily transport.

AP2 (2004–2009): Considered Evolution

From 2004, Honda rolled out the AP2 with changes that went well beyond cosmetic freshening. Engineers revisited engine displacement, suspension geometry, wheel sizing, and interior quality in a coordinated effort to widen the car's appeal without discarding its character. The changes were applied somewhat differently across markets — Japan and North America received distinct engine specifications — but the underlying intent was consistent: make the S2000 more accessible without dulling it.

The Engine: Two Different Philosophies in a Similar Package

AP1: F20C — 2.0 Litres, 9,000 RPM

The AP1's F20C produced around 240 horsepower from 2.0 litres, achieving one of the highest specific outputs of any naturally aspirated production engine at the time — roughly 120 hp per litre. In most markets the redline sat at 9,000 RPM, and the power band was deliberately concentrated near the top of the rev range. That characteristic defined the entire driving experience: to access the F20C's full capability, the driver had to commit, shift late, and stay on top of the tachometer. Throttle response was immediate, and the final push toward redline carried an intensity few road cars could match.

AP2: F22C1 — 2.2 Litres, 8,200 RPM

For the U.S. market and several other regions, Honda replaced the F20C with the 2.2-litre F22C1. Peak horsepower held at 240, but the additional displacement reshaped the torque curve, filling in the mid-range that the AP1 had largely ignored. Redline dropped to approximately 8,200 RPM — still exceptional by any conventional benchmark, but a noticeable step down for drivers accustomed to the AP1's stratospheric ceiling. The practical benefit was real: the AP2 engine pulled cleanly from lower revs, making urban driving less of an exercise in clutch and throttle management.

Exterior: Functional Updates, Not Reinvention

AP1 Styling

The original S2000 wore a clean, low-slung body with short front overhangs and smooth surfacing that kept visual clutter to a minimum. Standard 16-inch wheels suited the car's lightweight focus and contributed to the lean, purposeful look Honda's designers intended.

AP2 Updates

Honda revised the front and rear bumpers for the AP2, along with updated headlight and taillight housings that gave the car a sharper face. The more consequential change was the move to 17-inch wheels, which not only altered the visual proportions but also created clearance for wider rear tyres — a functional requirement tied directly to the suspension and handling revisions made simultaneously. Small aerodynamic adjustments improved high-speed stability without requiring a full body redesign.

Interior: Incremental Improvements to a Driver-First Cabin

AP1 Cabin

The AP1's interior was built around the driver. The digital instrument cluster was angled for fast, at-a-glance readings during hard driving, and the seats offered lateral support that reflected the car's track intentions. Some dashboard and door panel plastics showed obvious cost discipline, consistent with Honda's priority of keeping weight down over adding luxury.

AP2 Cabin

Honda upgraded several interior surfaces for the AP2, replacing the most obviously budget plastics with better-quality finishes. Seat design and minor control placement received ergonomic attention. The cabin remained minimalist by design, but the AP2 struck a more convincing balance between performance cockpit and daily-use interior.

Transmission and Drivetrain

Both variants use a close-ratio 6-speed manual gearbox with short, precise throws widely regarded as among the best of any production car. The AP2 received revised gear ratios calibrated to the F22C1's broader torque delivery, making better use of the mid-range without compromising the tactile quality that made the shifter famous. Underpinning both versions was a Torsen limited-slip differential, central to the S2000's ability to put power down cleanly and maintain its playful rear-wheel-drive balance under hard acceleration and in corners.

Suspension and Handling

AP1: Precise and Demanding

The AP1's chassis was highly responsive and, in the hands of an inexperienced driver, occasionally unforgiving. Turn-in was sharp, body roll was minimal, and the car would rotate eagerly at the limit — a quality that was thrilling on circuit but required careful management on wet public roads. Drivers who respected its demands were rewarded with a level of engagement that rivalled purpose-built track cars.

AP2: More Planted, Still Alive

Honda's engineers revised spring rates, shock damping, and anti-roll bar tuning for the AP2, and combined those changes with the wider rear tyres enabled by the 17-inch wheels. The result was a more predictable rear end at the limit without eliminating the car's fundamental willingness to rotate. Mountain roads and track days remained firmly within its natural habitat; the car simply inspired more confidence getting there.

Safety Features

Both AP1 and early AP2 models were built on Honda's X-bone monocoque chassis, which contributed meaningfully to crash protection. Standard equipment included ABS, dual airbags, and a rigid structure. A significant addition to later AP2 models was Vehicle Stability Assist (VSA), an electronic stability system designed to catch slides before they developed into spins. Purists tended to leave it off; less experienced drivers found it a useful safety net on the road.

Special Editions: The CR and Others

Honda released various limited editions throughout the S2000's production life, covering unique paint options, interior trims, and factory performance upgrades. The most significant for enthusiasts was the Club Racer (CR), produced during the AP2 era for the U.S. market.

The CR was built specifically for track use. Honda fitted a larger rear spoiler and front splitter to improve downforce, removed the soft top in favour of a lightweight removable hard top, stripped sound insulation, and made air conditioning and the audio system optional deletions. Suspension received further calibration with stiffer dampers, springs, and anti-roll bars. The CR remains among the most sought-after S2000 variants on the used market, combining the AP2's more accessible chassis with the sharpest factory track setup Honda ever offered for the car.

Driving Character: How They Actually Feel

AP1: Committed and Unfiltered

The AP1 asks more of its driver than almost any contemporary road car. The 9,000 RPM ceiling demands precise, high-rev shifting, the chassis rewards clean inputs and punishes lazy ones, and the narrow power band means casual driving yields a fraction of the experience the car is capable of delivering. On a good road or a circuit, few naturally aspirated roadsters of its era came close to matching it. In traffic or on a wet motorway, it required more concentration than many drivers wanted to provide.

AP2: Broader Range, Same Core

The AP2 keeps everything essential about the S2000 intact while extending the window in which it performs well. The torque improvement means useful drive from lower revs, the chassis changes mean greater stability at the limit, and VSA availability gives less confident drivers a degree of electronic assistance. None of this makes the AP2 a soft car — it remains a genuine sports car requiring driver involvement — but it earns its broader appeal honestly, through engineering rather than compromise.

Which One Is Right for You?

The AP1 is the choice for drivers who want the most direct, unfiltered version of what the S2000 was designed to be. Its 9,000 RPM engine and demanding chassis represent Honda's original brief executed without concession. The AP2 is the choice for drivers who want that same fundamental character but with a wider operating range, better grip, and an interior that sits closer to the standard set by the car's contemporaries. Neither is wrong — they answer different questions about what a sports car should prioritise.

Key Takeaways

• The AP1 uses a 2.0-litre F20C with a 9,000 RPM redline and approximately 240 hp; the AP2 uses a 2.2-litre F22C1 with a redline of approximately 8,200 RPM at the same peak power figure, but with broader mid-range torque.
• AP2 exterior changes were functional as well as aesthetic: the move from 16-inch to 17-inch wheels enabled wider rear tyres, supporting revised suspension geometry rather than simply updating the look.
• The AP1 chassis is sharper and less forgiving at the limit; the AP2's recalibrated springs, dampers, and anti-roll bars deliver more predictable behaviour without eliminating the car's rear-drive playfulness.
• Vehicle Stability Assist appeared on later AP2 models only — the AP1 offered no electronic stability intervention.
• The AP2-era Club Racer (CR) remains the most track-focused factory S2000 variant, with aerodynamic additions, significant weight reduction, and stiffer suspension calibration.
