Honda Project 2&4 powered by RC213V brought motorcycle and automobile design ideas together at Frankfurt in September 2015.

History and purpose

Honda Project 2&4 powered by RC213V brought motorcycle and automobile design ideas together at Frankfurt in September 2015. Honda’s original announcement identifies the physical concept and the collaboration between its Asaka and Wako design studios. The result is valuable as an experimental vehicle in its own right. It should not be catalogued as a road-approved production car or assigned a one-car total merely because one display object is photographed. The archive retains the concept identity and an unknown complete fabrication tally. Its most immediately legible idea is the placement of the occupant within a machine that exposes much of its structure.

Design and engineering

Honda published a 999 cc V4, more than 215 PS, 118 Nm, a six-speed dual-clutch transmission and a 405 kg mass for the concept. These are announced specifications, not results independently measured for the displayed example. The supplied photograph shows the floating-seat idea clearly: the seat and controls sit within an open arrangement beside the main body. Exposed wheels and visible structural relationships make the concept unusually informative from a single view. Readers can see how the body surrounds the machine differently from HSC or an NSX. The image does not, by itself, establish a running condition or a legal road-use status.

Identifying the original configuration

The selected source names Project 2&4 at the 2015 Frankfurt IAA and dates the image to 22 September. Preserve the full powered-by-RC213V wording as part of its original identity, rather than shortening it into a generic race-car heading. Honda’s launch account supplies the engine proposal and design collaboration. A fuller archive could add cockpit details, construction records and any documented operating demonstrations. Each should state its date and the physical object involved. Display specifications and later testing are different evidence, just as an exposed design does not mean that every visible component remains in its original construction state.

Collector context and preservation

Project 2&4 makes a strong visual comparison with HSC and EV-STER. Their photographs describe three different ways to place a driver inside an experimental sports vehicle: enclosed coupe, small open cockpit and exposed seat. That comparison can explain the design without an invented lap time or a speculative retail plan. A collection file should preserve structural details, finishes and control interfaces with the same care given to the power-unit description. If subsequent work altered the seat, body or mechanical installation, retain it as a dated event. This lets the concept’s individual history expand while maintaining the meaning of Honda’s original 2015 proposal.

Reading the evidence for this profile

The original source links below identify the programme and the historical statements used in this article. The photograph has its own creator and licence record, separate from the manufacturer’s vehicle history. Keep both when transferring this profile into a collection catalogue. A manufacturing tally describes how many cars belong to a defined original programme; it does not measure how many survive, how many are publicly visible, or how many retain all their original components. Those individual questions require dated chassis and restoration evidence. The reference year likewise describes the programme’s introduction or named historic configuration, while the supplied caption states the photographed setting and any established individual identity. This lets future research expand the car’s history without blurring the scope of the record already assembled here.

Frequently asked questions

What is the Honda Project 2&4 powered by RC213V?

A physical Honda experimental sports concept combining motorcycle-derived power with an exposed driver arrangement, presented in Frankfurt in 2015.

What engineering defines this vehicle?

999 cc V4; Honda announced more than 215 PS and 118 Nm. Published six-speed dual-clutch transmission; exposed floating-seat concept; announced mass 405 kg. The specifications describe the original programme or published concept proposal. An individual example’s installed equipment and any later changes need their own dated evidence.

Why does this profile use 2015?

This is the documented introduction or original configuration year. Photograph dates and market model years can differ. Keeping those dates separate makes it possible to follow the car’s development without creating a second identity for the same programme.

How should an individual Project 2&4 powered by RC213V be authenticated?

Connect the chassis identifier to original delivery, edition or custodial records. Compare period exterior, cabin and mechanical photographs with the documented configuration. Record replacement parts, paint changes and restoration work as dated events. A badge or colour alone cannot establish that a car belongs to this original programme.

What rarity or archive scope is verified?

Physical Honda Project 2&4 concept presented at Frankfurt in September 2015. Complete fabrication tally unknown. Published power, mass and transmission figures are concept specifications, not independent measured results or proof of road approval.
