Why it matters
The GT9-R was the most extreme stage of 9ff's GT9, a mid-engined car that is loosely based on the Porsche 911 but has almost everything built from scratch. 9ff offered it with three engine stages and claimed a top speed of 414 km/h for the strongest, a figure presented as a challenge to the then-record 412 km/h of the SSC Ultimate Aero TT. The claim was stated as pending outside verification.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionannounced production limit | 201 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
9ff announced the GT9-R as a development of the existing GT9, which at the time was quoted at 973 horsepower and 409 km/h. The press release says the car was limited to 20 pieces worldwide, each configured to the customer's wishes as either a top-speed or a track-performance model with different aerodynamic packages.
The engine was offered in three stages that could be upgraded at any time: a 750 HP kit (380 km/h), a 987 HP stage (409 km/h) and a 1120 HP stage (414 km/h). Three gearbox types were listed: a 6-speed manual, a 6-speed sequential and a 5-speed Tiptronic that could only be combined with the 750 HP stage.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
Each car is built to individual order, so no single specification identifies it. Features stated by 9ff are the mid-engined layout, a 4.0-litre six-cylinder boxer engine, lightweight construction and the choice of three engine stages (750, 987 or 1120 HP), with 6-speed manual, 6-speed sequential or 5-speed Tiptronic gearboxes (Tiptronic only with the 750 HP stage).
