Start with a single garage and a sketch. Build the automaker that outlasts the century.

Nothing here happens on reflex. Every turn is a deliberate bet — which technology to chase, which segment to defend, what to charge, and when to stake the company on a factory you cannot yet afford. Then the market answers, your rivals answer, and you live with it. One hundred years and five eras separate the garage from the boardroom, and the decisions you make in the first decade are still compounding in the last.

Design cars from the chassis up

Every model is yours to engineer. Choose from 12 body types, size the engine, pick your components, and balance the trade-offs with fine-grained tuning sliders.

• Engineer the trade-offs — performance, comfort, reliability, fuel economy and cost all pull against each other. There is no perfect car, only the right car for the segment you're chasing.
  
• Live with your decisions — defects, aging stats and facelifts decide whether a model stays competitive or quietly stops selling.
  
• Build a lineup, not a one-hit wonder — cover the segments that matter, retire what's gone stale, and time each successor.

Research the tech that wins decades

Progress down a historical technology tree of 103 technologies spanning five eras, and unlock the engines, materials and features that define each one.

• Time your research bets so your cars lead the market instead of trailing it.
  
• New tech reshapes what's possible — and quietly makes last decade's bestseller obsolete.

Run the whole business

A great car is only half the company. Build and manage the operation behind it.

• Manufacturing — factories, production lines, shifts and retooling. Match output to demand without drowning in unsold stock.
  
• Pricing — set every model's price against what your rivals are asking. Undercut them and their buyers become yours; hold your price and let the badge carry it. Go too cheap and buyers simply read it as a cheap car.
  
• Money — fund R&D, manage cash flow, and use financing to grow faster than your balance sheet should allow.
  
• Brand — marketing builds reputation and prestige, and they shift how buyers rank you against an otherwise identical rival. Let a defect slide and it drags them back down. A trusted badge sells cars a spreadsheet says it shouldn't.

Outplay a field that grows to 30 living rivals

The competition isn't scenery. Every AI manufacturer runs the same logic you do — designing, pricing, researching and reacting, turn after turn — and the field keeps filling as the century goes on, until as many as 30 of them are fighting you for every sale.

• Scout rivals, read the standings, and exploit the gaps they leave open.
  
• Survive market shocks and events that punish the complacent.
  
• No two centuries run the same — every run is seeded, so a new game reshuffles the rivals, the market and the shocks you will face.
  
• Change your own starting hand — four difficulty levels, three company traits picked at founding, and a starting-skill build that decides what you are good at before you build anything.
  
• Climb the rankings to the top of the industry — or go bankrupt trying.

Read everything, miss nothing

The reports are there so you can act on the simulation instead of guessing at it: company value over time, market share, profit margins, sales versus the competition, financials and cash flow, and a full company history — fourteen tabs, each answering a question you will actually have.

When the run ends, a detailed scorecard and leaderboard tell you exactly how you stacked up: a hundred years of decisions, measured against every rival who tried. At the very start of that history, a sketch, a single garage, and a badge you had to think of a name for.
