How to start it
Climb in (Rimac's butterfly / Koenigsegg's dihedral doors open automatically with the key in pocket). Press the brake, hit the central START button — the car is silent on Rimac, the Koenigsegg twin-turbo V8 catches immediately.

Overview
About the Koenigsegg One:1
The name is the specification. One:1 refers to a power-to-weight ratio of exactly one metric horsepower per kilogram: 1,341 hp, 1,360 kg. Koenigsegg called it the world's first megacar, and the whole car was designed around hitting that number rather than around a styling brief.
Getting there meant obsessive subtraction. The 5.0-litre twin-turbo V8 was fitted with a variable-geometry turbo setup unusual on a petrol engine, 3D-printed titanium exhaust components, and a titanium exhaust system light enough to lift with one hand. The carbon wheels, carbon monocoque, and carbon body panels were all part of the weight equation, not a luxury upsell.
The aerodynamics were equally single-minded. A large active rear wing, a fully active chassis with adjustable ride height, and an underbody that made real use of ground effect gave the One:1 roughly 610 kg of downforce at 160 mph — figures previously associated with prototype race cars rather than road-registered coupés. In 2014 it took the production-car Suzuka lap record.
Six were built plus a prototype, and all six were sold before the car was shown. The One:1's real legacy is conceptual: it introduced the megacar as a category, and it forced everyone else to start quoting power-to-weight rather than power alone.
How to use
Owner's walkthrough
Practical guide for everything a new owner asks on day one — starting the car, finding the gear selector, drive modes, infotainment, driver aids, and easy-to-miss features.
02
Where the gear selector is (and how to use it)
Milled-metal manual selector between the seats — R / N / D / S clearly engraved; engage paddles after launching D.
03
Drive modes
Drive modes are accessed via the touchscreen drive-mode panel. Available modes typically include Wet, Normal, Sport, Track, ESC-Off. Each mode reshuffles throttle mapping, steering weight, adaptive dampers (if equipped), exhaust valves, and stability-control thresholds. On performance trims, an 'Individual' or 'Custom' slot lets you save your favorite combination so you can recall it with one click instead of nesting through menus.
04
Cluster & head-up display
The driver display is a Steering-wheel mounted curved display (rotates with wheel). Use the steering-wheel left thumb-pad to cycle layouts (Classic, Sport, Navigation, Minimal). When in Sport / Track mode the cluster automatically swaps to a wide tach with gear indicator and tire-temperature readout. The head-up display brightness, height, and content are configured from Settings → Displays → HUD.
05
Infotainment & voice control
Infotainment runs on Koenigsegg SmartCenter (touchscreen, gesture-aware). Wireless Apple CarPlay and Android Auto are standard; pair from Settings → Connections the first time, then it auto-connects whenever your phone is in range. n/a wakes the in-car assistant for nav, climate, calls, and messaging without touching the screen. The main display also hosts vehicle-specific apps: tire pressures, performance data recorder (where fitted), drive-mode customizer, and the camera views.
06
Driver assistance
Standard driver aids include adaptive cruise control, lane-keeping assist, automatic emergency braking, blind-spot monitoring, and rear cross-traffic alert. Toggle each system individually from the driver-assist menu (steering-wheel left-pad → Assistance). Highway-driving assist (hands-off in marked lanes on supported roads), automatic lane-change on indicator tap, traffic-jam assist for stop-and-go, and a 360° surround camera with transparent-hood mode are all available and worth enabling for the first time before driving in heavy traffic.
07
Fueling
Premium unleaded (91 or 93 octane) is required on Koenigsegg performance models — the engine timing is set for it and lower octane causes audible knock and reduced power. Fuel-cap release is a button on the driver door panel; the cap is capless (just push the nozzle in).
08
Keys & phone-as-key
Beyond the physical key, this car supports Smart key. Set up phone-as-key from the Koenigsegg Owners portal app: it provisions a secure credential to your phone's wallet so a tap on the door handle unlocks the car and placing the phone on the wireless charging pad authorizes ignition. You can also share temporary keys to family members (with optional speed and area limits on performance trims) directly from the app.
09
First-week tips & easy-to-miss features
A few things every new owner tells us they wish they'd known on day one:
- Always use the front-axle lift before driveways and speed bumps — it stores the lift point in GPS so the car raises automatically next time.
- Warm tires and oil for at least 8–10 minutes before using Race / Track mode; cold rubber on this much power is the #1 cause of off-throttle spins.
- Download the brand app (Koenigsegg Owners portal) and pair it with your VIN before your first long trip — remote climate, charging/fuel-level checks, and remote lock-status save you walking back to the garage in winter.
