My Summer Car is a brutally authentic Finnish countryside survival and car-building simulator set in 1990s rural Finland. You must assemble a Satsuma AE86 car from hundreds of individual parts, bolt by bolt, while managing hunger, thirst, fatigue, and the ever-present temptation of beer. The game's world is a fully realized Finnish summer experience — you can sauna, go fishing, drive a sewage truck for money, or get killed by a drunk driver on a country road. The physics-based car assembly requires mechanical knowledge, and one mis-tightened bolt means your engine falls apart at highway speed.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
car assembly
The Satsuma car starts as 200+ individual parts scattered around a garage. You must physically bolt each part into the correct position: engine block, pistons, crankshaft, gearbox, exhaust, electrical, cooling, fuel systems. Every bolt must be tightened with the correct wrench size. One missing or loose bolt means parts fall off while driving. The assembly process can take 10+ hours for first-time players.
survival needs
You manage hunger (eat sausages, buy groceries from the shop), thirst (drink from taps, buy juice or beer), fatigue (sleep in your bed or sauna), urine (use toilets or suffer), and stress (reduced by sauna, beer, or driving). Ignoring needs causes debuffs and eventually death. The survival mechanics add constant pressure while working on the car.
Finnish countryside
The open world simulates rural Finland with dirt roads, lakes, forests, a small town, and neighboring properties. NPCs drive on roads (and will kill you if you're in the way), the local store sells groceries and car parts, and seasonal events add variety. The world is small but densely interactive.
job system
You earn money through odd jobs: driving the septic truck to pump septic tanks, chopping firewood for neighbors, delivering groceries, and winning the rally race. Money buys car parts, groceries, fuel, and repairs at Fleetari's garage. The economy is tight — you must work to afford the car parts needed to finish the Satsuma.
part ordering
Some car parts aren't available locally and must be ordered from a catalog (delivered by mail) or purchased from Fleetari's repair shop at premium prices. Ordering takes 2-3 in-game days for delivery. Planning part orders in advance prevents frustrating waits when you're ready to assemble.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Mechanic | S | Methodically assemble the car part by part, test after each major system, tune for performance. | Part identification, bolt order knowledge, engine tuning |
| Rally Driver | A | Tune the Satsuma for rally performance, practice the course, race for prize money. | Car tuning, driving skill, course knowledge |
| Farmer | B | Chop and deliver firewood for steady income to fund car assembly. | Efficiency, route knowledge, vehicle handling |
| Delivery Driver | B | Drive the septic truck between pumping locations, manage the gross but profitable waste removal business. | Driving skill, route efficiency, septic tank location knowledge |
| Fisherman | C | Fish for food and quest items, enjoy the relaxing lake scenery between car work sessions. | Patience, fish location knowledge, boat handling |
Mechanic (S-Tier): The core gameplay — assembling the Satsuma from parts. Mechanic knowledge (bolt order, part placement, tuning) determines how quickly and correctly you build the car. The Satsuma has a realistic engine model: incorrect timing, lean/rich fuel mixture, or missing bolts cause failures.
Rally Driver (A-Tier): After building the Satsuma, you can enter it in the local rally race. Rally driving requires a well-tuned car with proper suspension, roll cage, and racing seat. Winning the rally pays significant money and is one of the game's most satisfying achievements.
Farmer (B-Tier): The firewood-chopping job provides steady income early game. Cut logs at the neighbor's property, load them on a trailer, and deliver them for payment. Farming money funds initial car part purchases. Tedious but reliable income.
Delivery Driver (B-Tier): The septic truck (sewage pumping) job pays well per delivery. Drive the truck to septic tank locations, pump them empty, and deliver the sewage to the treatment plant. The truck handles poorly and the job is gross, but the money is good.
Fisherman (C-Tier): Fishing in the local lake provides food (saving grocery money) and catches specific fish needed for NPC quests. Fishing is slow but relaxing and self-sufficient. Not a primary income source but supplements food supply.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Satsuma Car | The game's centerpiece — a Datsun 100A (rebadged as Satsuma AE86) that you assemble from scratch. | Mechanic — the entire game revolves around this car |
| Wrench Set | Multiple wrench sizes (8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm) needed for different bolts throughout the car. | Mechanic — essential tool for every assembly step |
| Beer | Finland's national beverage, available from the store and home fridge. | Stress relief, sauna companion, rally spectator fuel |
| Sauna Stove | The home sauna heats up when you add firewood and water to the stove. | Stress management and the authentic Finnish experience |
| Sewage Truck | The company vehicle for the septic pumping job. | Delivery Driver for earning money to buy car parts |
Satsuma Car: The game's centerpiece — a Datsun 100A (rebadged as Satsuma AE86) that you assemble from scratch. Every bolt, gasket, wire, and fluid must be correctly installed. The finished car can be tuned for daily driving, rally racing, or show condition. Building the Satsuma IS the game.
Wrench Set: Multiple wrench sizes (8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm) needed for different bolts throughout the car. Using the wrong size wrench won't tighten the bolt. The wrench set is your primary tool — without it, no assembly is possible.
Beer: Finland's national beverage, available from the store and home fridge. Beer reduces stress but increases drunkenness, impairing driving and walking. Drinking too much causes blackouts, waking up in random locations. A core part of the Finnish summer experience.
Sauna Stove: The home sauna heats up when you add firewood and water to the stove. Taking sauna reduces stress, cleans you, and provides a warm place to relax. The sauna is a game mechanic and a cultural experience. Overheating in the sauna can kill you.
Sewage Truck: The company vehicle for the septic pumping job. Drives like a brick on ice, especially on dirt roads. The truck itself is indestructible but you can die if you crash it into a lake. Your primary money-making vehicle until the Satsuma is finished.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Home | Hub area | Save point, car assembly location, food storage, sauna access |
| Fleetari Repair Shop | Shopping location | Advanced car parts, repair services, rally inspection, paint jobs |
| Teimo Shop | Shopping location | Food, drinks, basic car parts, motor fluids, beer |
| Highway | Travel route | Fast travel between locations (dangerous), NPC traffic encounters |
| Dirt Track | Rally event location | Rally race (prize money), driving practice, course knowledge |
Home: Your family's rural property with the garage (Satsuma assembly), sauna, bedroom (save point), kitchen (food storage), and yard (firewood chopping). Home is your base of operations for the entire game. The garage has a lift for underneath access.
Fleetari Repair Shop: The local car mechanic who sells advanced parts, performs repairs, and handles paint jobs. Fleetari's prices are high but he has parts not available elsewhere. He also inspects your car for rally eligibility. Located on the main road.
Teimo Shop: The only store in town selling groceries, motor oil, brake fluid, and basic car parts (filters, spark plugs). Teimo also sells beer, sausages, and cigarettes. Open during daytime only. Essential for daily survival supplies.
Highway: The main asphalt road connecting all locations. NPC drivers use this road and WILL kill you if you're in their way (drunk driving NPCs are common). The highway is the fastest route between locations but the most dangerous. Speed limit signs exist but nobody follows them.
Dirt Track: The rally course used for the local race event. A winding dirt road through forest with jumps, tight turns, and water crossings. Practice the track before race day. The rally is one of the game's main money-making and achievement goals.
Tips That Actually Matter
- Assemble the Satsuma engine in the correct bolt order — tightening bolts out of order can prevent parts from fitting. Follow a build guide for your first playthrough to avoid 10+ hours of trial and error.
- Save at toilets (sitting on the toilet saves the game) — death from any cause (starvation, car crash, NPC driver, wasp attack) resets to your last save. Save frequently.
- Beer reduces stress but affects driving — moderate drinking is fine, but being blackout drunk while driving the Satsuma on the highway is how most first cars are destroyed.
- Tighten every bolt until the socket wrench no longer moves — loose bolts cause parts to fall off while driving. An engine bolt coming loose at 120 km/h is catastrophic.
- Order parts from the catalog if Fleetari's shop is too expensive — catalog parts are cheaper but take 2-3 game days to arrive by mail. Plan ahead.
- The sewage truck is your best early income — pump septic tanks around the countryside and deliver to the treatment plant. Each delivery pays enough for several car parts.
- The Satsuma's electrical system is the trickiest assembly — alternator, battery, wiring harness, and fuses must all be correctly connected. A missing ground wire prevents the car from starting.
- Fuel mixture on the carburetor must be tuned — too lean (not enough fuel) causes overheating, too rich (too much fuel) wastes gas and reduces power. Adjust the screw by small increments.
- NPC cars on the highway drive erratically and will run you over. Stay on the shoulder or use the dirt roads for safer travel. The green car is particularly dangerous.
- The sauna prevents death from stress — extreme stress without relief eventually kills you. Visit the sauna every 2-3 game days to keep stress manageable.
Common Mistakes to Avoid
- Not saving frequently — the game auto-saves only when you sleep or use the toilet. Dying from any cause (car crash, hunger, wasp sting) without a recent save means losing hours of progress.
- Attempting to drive the Satsuma before fully assembling and testing it — missing parts cause immediate breakdowns. Start the engine in the garage first and listen for problems before driving.
- Drinking too much beer before driving — the drunk driving physics are realistic and punishing. Even moderate intoxication causes swerving that can send you off the road into a tree.
- Forgetting to check all bolt tightness — a single loose bolt in the engine can cause catastrophic failure at speed. Systematically check every bolt with the wrench before driving.
- Not ordering parts in advance — waiting until you need a part, then ordering it, wastes 2-3 game days. Order all needed parts at the beginning of each game week.
Frequently Asked Questions
