Build a Car Company Tier Lists
S–D rankings for powertrains, body shells, and research paths based on progression value.
Tier lists in Build a Car Company answer a simple question: where should your next Cash and Research Points go? This hub ranks engines, bodies, and research priorities for progression value—not just peak fantasy horsepower.
Use these lists with the Design Cars and Factory guides so rankings turn into actual company growth.
Current lists
- Engines Tier List — which powertrains to buy early, mid, and late
- Bodies Tier List — compact, sedan, sport/GT, luxury, rally, and experimental shells by tooling vs sell-through
- Research Priority Tier List — which of the 130+ technologies pay back first
| List | Best when you need… |
|---|---|
| Engines | More score, pace, or reliability from the powertrain |
| Bodies | Better sell-through, crash friendliness, or SKU roles |
| Research | Clearer unlock order across 130+ techs |
All three lists assume a standard progression account after redeeming codes. Pure race-only saves may shift a few ranks—notes call those out.
How we rank
| Tier | Meaning |
|---|---|
| S | Best progression value right now |
| A | Excellent; build around it |
| B | Solid situational picks |
| C | Usable fillers or transitional |
| D | Trap options for most players |
Criteria mix unlock cost, reliability impact, sales lift, race usefulness, and synergy with factory upgrades. Flashy endgame tech can sit in B or C until your plant can afford it.
How to use a tier list in-session
- Open the list that matches your bottleneck (power, body/shell, or research).
- Cross-check what you have already unlocked.
- Buy the highest tier option you can actually equip this session.
- Re-test crash scores after any engine or body swap.
- Revisit after updates—Admin Abuse can move ranks.
Synergy reminders
- An S-tier engine on a D-tier chassis still fails crash tests.
- An S-tier body with a mismatched micro engine still hurts brand scores.
- S-tier research that boosts line speed multiplies every seller.
- Race specials may justify a higher engine or sport body tier sooner—see Racing.
- Staff efficiency changes how fast you climb tiers (Hiring).
What this hub is not
These are not pay-to-win flex charts. Robux cosmetics rarely change tier placements. Scripts that unlock everything skip the point of ranked progression advice—read Scripts if you are curious, but play fair when you can.

Pick a list, spend with intent, and your next upgrade will feel like progress instead of a coin flip.
Updating ranks after live ops
When Sunset Entertainment ships an Admin Abuse or patch, re-test your current S and A picks for one production batch before mass tooling. A temporary event engine or shell can look S-tier for a night and fall back to B the next morning.
Keep notes on which research node unlocked your last sales spike. That anecdote often matters more than a generic chart when you only have twenty RP left. Share the same discipline on race weekends: do not swap an entire powertrain or body mid-grid unless crash scores stay green.
For quick navigation, pin Engines, Bodies, and Research Priority beside Make Money Fast while you spend.
Frequently Asked Questions
Quick answers to the most common questions.
Which tier list should I open first?
If cars feel weak, open Engines. If sell-through or crash mass is the problem, open Bodies. If unlocks feel random, open Research Priority.
Do tiers change after updates?

Is S-tier always mandatory?
No. Buy the best tier you can afford and equip now. Waiting forever for S while the line idles loses Cash.

No. They are written only for Build a Car Company by Sunset Entertainment.
