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.
The 2017 Koenigsegg Agera RS combines 5.0L Twin-Turbo V8 with RWD. Its catalog figures are 1,360 hp, 3,075 lb, and a price near $2.50M. The catalog lists 0–60 mph in 2.8 seconds and a 278 mph top speed.

Performance, build, and ownership-cost composite.
For a while, this was simply the fastest car in the world. In November 2017, on a closed stretch of Nevada's Route 160, an Agera RS averaged 277.9 mph over two runs, with a one-way peak of 284.55 mph, taking the production top-speed record from Bugatti. It also set 0–249–0 mph and 0–186–0 mph records in the same period. Twenty-five were built.
The Agera RS was the last and hardest version of a car that had been iterating since 2011. Its 5.0-litre twin-turbo V8 made around 1,160 hp as standard and up to 1,360 hp with the optional 1MW package, all in a car weighing roughly 3,075 lb dry. Koenigsegg's carbon monocoque, hollow carbon wheels — a Koenigsegg first, saving nearly 20 lb of unsprung mass per set — and active Triplex rear suspension did the rest.
What made it usable was the active aero. The dynamic rear wing trims for downforce or drag depending on mode, so the same car that generated serious grip on a circuit could flatten itself for a record run.
The Agera RS marks the moment Koenigsegg stopped being the plucky Swedish outsider and became the benchmark. Every top-speed claim since — including from Bugatti and SSC — has had to be argued against what happened on that Nevada highway.
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.

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.
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.
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.
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.
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).
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.
