Frequently asked questions about Koenigsegg One:1

Why is it called One:1?
The name references the 1:1 power-to-weight ratio. 1,360 horsepower (or 1,000 kW) with 1,360 kg curb weight provides exactly 1:1 power-to-weight ratio. Koenigsegg targets this benchmark as engineering achievement for the One:1.
How much does a One:1 cost?
Used pricing: $5-8 million+. Original MSRP was around $2.85 million. Pricing has appreciated significantly due to extreme rarity (7 cars total). The One:1 is one of the most valuable modern Koenigseggs.
How fast is One:1?
Top speed estimated 273 mph based on aerodynamic projections, but no production-trim verified record. Focused on lap times rather than top speed. The One:1 was designed for track and aggressive driving rather than top speed records.
What replaced the One:1?
The Jesko (2019+). New platform, more refined engineering. The Jesko Attack (track-focused) and Jesko Absolut (top-speed-focused) succeed the One:1 with greater production volumes and updated technology.
Is One:1 reliable?
Generally yes for hand-built hypercars. Limited production means most One:1 cars are kept in storage rather than driven extensively. Common issues are typical for low-volume hypercars. Maintenance is extremely expensive.
