Feature Model Details

The Ferrari 812 Superfast Onyx 8XX listed for sale on DubiCars from Dourado Luxury Cars is 1 of 5 available models. The 8XX is made by Onyx Concept and features some exclusive touches. This includes carbon-fibre body parts, performance exhaust, tuned engine and reworked interiors.

Exterior Design — Onyx Package

Ferrari gave the 812 Superfast glorious Italian design that looked like automotive art. However, Onyx Concepts took the standard supercar and gave it a ton of carbon fibre parts and an exclusive exterior paint scheme to make it look menacing.

Interior Design — Onyx Package

The changes on the 8XX’s interiors are fewer as compared to its exterior. Most of the equipment such as the climate control, digital cluster, passenger display, and JBL audio have been carried over from the standard 812 Superfast. However, the changes on the inside made by Onyx include:

  • Carbon fibre accents on the dashboard, steering wheel, and centre console
  • Leather seats with yellow accents


The 812 Superfast Onyx 8XX features a digital instrument cluster, a head-up display, and an infotainment system that seamlessly integrates navigation, audio, and climate control. While not the most advanced system compared to modern luxury cars, it provides all the necessary features while maintaining a driver-focused environment. There have been no changes in this department from Onyx.

Engine & Performance — Onyx Tuned

The 6.5-litre naturally-aspirated engine is tuned to produce 101hp more than the stock Ferrari 812 Superfast. The stock performance stood at 0 to 100km/h in 2.9 seconds and a top speed of 340km/h.

Onyx has not revealed the 8XX’s performance figures. However, the limited-edition supercar is lighter and more powerful than the stock Superfast and will result in quicker acceleration and faster top speed.  

Driving Impressions

The hunkered-down 812 Superfast was already an incredibly responsive and agile supercar. Onyx Concepts have further stiffened the electronically adjustable suspension to make the car rigid and handle better around corners and straights. Overall, the 8XX delivers edge-of-the-seat action when you trod on the loud pedal no matter which way you turn the steering wheel.
