Mashing Guide

How mashing works

When you mash two vehicles, Whipmash sends both to our AI backbone, which analyses the visual and mechanical characteristics of each parent and generates a new vehicle that plausibly combines them.

The AI produces a name, description, and a unique image for the mashup. No two mash runs produce the same result — even mashing the same pair twice will give you a different vehicle.

Step-by-step

1. Go to Mash and select your first vehicle (Parent A). You can pre-select it from the vehicle detail page with the ↺ Mash button.
2. Select a second vehicle (Parent B) from your garage using the picker.
3. Click Generate. The system fires 4 parallel AI requests — one for each variant — so all four results arrive at roughly the same time.
4. Review the 4 variants. Click any variant to expand it. When you've found one you like, click Keep.
5. Kept mashups cost 1 token and appear in your garage immediately. Discarded variants are free.

The 4 variants

Each mash run produces 4 independent variant images of the same conceptual mashup. They share the same parents and the same AI-generated name/description, but the visual representation differs between variants.

• Variants can range from incredibly detailed and photorealistic to stylised or abstract.
• One variant may focus heavily on Parent A while another leans toward Parent B.
• Occasionally all 4 are disappointing — that is the nature of generative AI. Discard and try again.

Tokens & cost

• Generating the 4 variants is free.
• Keeping a variant costs 1 token.
• Discarding all variants costs nothing.
• You receive a free daily token allowance. Check the Profile page for your remaining balance.

Multi-generation mashing

You can mash a mashup with another mashup (or a garage vehicle). There is no limit to the number of generations.

Why multi-gen?

• Combining mashups produces the most unusual and visually striking results — features from 3 or 4 source vehicles blend together.
• Mashing mashups together produces increasingly complex vehicles with traits from multiple sources.
• The Lineage panel on each vehicle's detail page shows its full family tree up to 2 generations back.

Combination tips

Not all pairings are created equal. Here are combinations that tend to produce the most interesting results:

What tends to produce poor results

• Two very similar vehicles (e.g. two sedans of the same era) — the result is often indistinguishable from either parent.
• Very small vehicles paired with very large ones — the smaller vehicle's features often get absorbed.

Quality issues & what to expect

AI image generation is imperfect. Here's an honest overview of what you'll encounter:

• ~70% of runs produce results that are uninspiring, physically odd, or don't clearly represent both parents.
• ~20% of runs produce decent mashups worth keeping for your garage or sharing.
• ~10% of runs produce genuinely striking vehicles — these are the ones worth sharing to the feed.

Common artefacts to watch for

• Impossible geometry — the AI sometimes generates physically implausible forms with mismatched proportions.
• Blurry or smeared surfaces — especially in multi-gen mashups with complex lineages.
• Wrong background — the image may include an environment when you'd prefer a clean studio shot (or vice versa).
• Disconnected features — one parent's elements may appear floating or pasted rather than integrated.

None of these are errors in the system — they are inherent to the current state of AI image generation. When you see them, simply discard and regenerate.
