4 Major Differences Between The AP1 and AP2
Since it was introduced in 1999, it experienced multiple revisions, all of which eventually lead to the AP2 design. While there were several updates introduced every year, there are four notable changes that occurred separating the AP1 and AP2 generations. We've taken the liberty to list those changes here. For those of you interested in learning about all of the revisions for every year the S2K was produced, click here. (For comparison's sake, we will not be discussing the AP2 CR and Type S).
1. Rev Limit
The AP1 was originally produced with the heritage of Honda’s Formula 1 in mind. This lead to the design of an amazing 2.0 naturally aspirated engine, with a 9200 rev limit. However, in 2004 the release of the AP2 showed a change in powertrain and introduced to the F22C1, with a rev limit of 8200.
In truth, the drop in RPM from 9200 to 8200 with the introduction of the AP2 was more of a mutual trade-off meant to satisfy some of the echoed woes of critics from the previous generation. While the 9200 Rev limiter made it a blast to drive, there were some complaints about power coming from the low-end. Honda’s solution was to install a stroker kit on the F20C, which would increase its overall displacement and torque. While the torque increase was only about 9 ft-lbs, it was available throughout most of the powerband, which in turn satisfied some the critics’ groans.

2. Gearing
Improving the engine’s overall torque curve wasn’t the only important change, as the drivetrain also received an update. Although it was introduced in 2006, the drive-by-wire (DBW) system removed the throttle cable and instead replaced it with a completely electric system. There have been some complaints on DBW, with some people commenting that there is a minimal delay between that and a cable transmission. However, it's mostly been anecdotal, with others completely disagreeing saying the system actually responds faster.
The gearing is also completely different. AP1 models have a lot longer gears, resulting in a higher top speed and a longer pull. It was one of the downsides of increasing the displacement. Still, the main difference only really affects the top speed of the car, as both perform equally well.

3. Suspension
Ask yourself one question. Are you interested in a road warrior or a comfortable cruiser? While both of the cars have stupendous suspension systems the actual components and their capabilities can make a variable difference depending on your driving style.
The AP1 is known for its stiffer spring rates as well as being much lighter than the AP2. Weight was saved by sticking as close to race car design as possible. So things such as a plastic rear window, instead of a glass windowpane were used to save weight. While the stiffer spring rates did make the ride harsher, the inclusion of a mechanical steering linkage, induced a more natural feeling. A lot of drivers comment on feeling more connected to the road when using an AP1.
On the other hand, the AP2 utilized softer spring rates to improve the overall comfort of the drive. The chassis also included several gizmos, along with a wheel and tire package, that increased the overall curb weight. These difference make the AP2 a solid choice for everyday driving, while many prefer the AP1 for motorsport.

4. Aesthetics
The most noticeable change between the two generations is the actual stylizing of the car. AP1 cars were definitely a lot more plain-jane–not that there’s anything wrong with that. Its body was made to look a lot more unassuming, and it utilized simple, but clean body lines to do it.
On the other hand, AP2s were definitely a lot more aggressive from the factory and had a bit more personality. The rear bumpers were lowered a bit more, with reshaped oval exhaust holes sterner lines. Because everything is interchangeable, many AP1 owners modify their car’s to fit AP2 front and rear bumpers.
Stock vs stock, the AP2 certainly beats the AP1 in the looks department. Even so, there are lots of aftermarket lip kits available, that can really bring out their inner beasts.
