The Onyx GT3x: Engineering Meets Artistry
The Onyx GT3x stands out in the world of luxury, where only a handful of models capture true automotive excellence. This car is more than a reimagined Bentley—it’s an experience crafted for supercar fans who crave the rare and the remarkable. In this guide, we’ll take an in-depth look at the GT3x, breaking down its engineering, unique editions, motorsport roots, and collector appeal.
Origins and the Onyx Concept
The Onyx GT3x finds its roots with Onyx Concept, a bespoke automotive modifier known for bold, performance-focused enhancements. While many stick to cosmetic changes, Onyx revolutionizes the platform using serious engineering upgrades. In the case of the GT3x, that starting platform is usually the mighty Bentley Continental GT, already a world-class grand tourer before Onyx transforms it into something exhilarating and rare.
Consequently, the GT3x serves as a halo car for the brand, showing off what’s possible when innovation and craftsmanship meet.
Model Evolution and Rare Editions
Throughout the years, Onyx Concept has steadily refined its GT-based offerings. The GT3x represents their most track-focused expression, inspired by the adrenaline-thumping Bentley GT3 race cars. However, the Onyx GT3x is strictly limited in production.
For example, only a small batch is built each year, making every car instantly collectible. Moreover, many GT3x versions come with custom features that make every single example unique in color, trim, and configuration.
- Limited to low double digits per year
- Each car hand-finished by Onyx artisans
- Special paintwork and carbon bodywork options
- Bespoke interiors for every client
Thus, if exclusivity is your priority, few cars deliver better than the GT3x. You can see trending examples or current listings here.
Powertrain and Track-Bred Performance
Under the hood, the GT3x gets a serious power boost over the standard Continental. Most frequently, Onyx reworks the 6.0-liter twin-turbocharged W12—or sometimes the punchy V8—using new ECU mapping, uprated turbochargers, upgraded intakes, and a performance exhaust system.
As a result, power outputs range from 700 to well over 800 horsepower, giving the GT3x acceleration on par with far more stripped-down supercars. 0-100 km/h sprints typically take under 3.5 seconds, and the top speed can exceed 335 km/h (208 mph) depending on spec. In addition, Onyx significantly refines the suspension and braking for sharper handling at the limit.
Technical Highlights of the GT3x
However, it’s not only about brute force. The GT3x receives motorsport-derived aerodynamics, including a carbon fiber front splitter, deep side skirts, a sculpted diffuser, and a towering adjustable rear wing.
Similarly, vented carbon hoods and wider fenders optimize cooling and airflow, turning the GT3x into a true street-legal race machine.
- ECU mapping with customizable power curves
- Motorsport-grade carbon body panels
- Active aerodynamic features
- Bilstein or Ohlins adjustable coilover suspension
- Carbon ceramic braking with six-piston calipers
Meanwhile, these upgrades blend luxury with aggression, offering real on-track performance without sacrificing comfort.
Interior Craftsmanship and Technology
In contrast to many hardcore track editions, the Onyx GT3x never forgets its luxury roots. Step inside, and you’re surrounded by rich leathers, Alcantara, exposed carbon, and contrast stitching.
Furthermore, Onyx offers limitless customization—clients can choose everything from seat quilting patterns to dash materials and even commission one-off inlays.
Most GT3x interiors feature:
- Hand-stitched sports seats with racing harnesses
- Custom steering wheels wrapped in Alcantara or carbon
- Upgraded Bentley infotainment with Onyx branding
- Lightweight trim options for true GT3 feel
Moreover, integrated track telemetry, data logging, and a premium sound system ensure the car remains as functional as it is beautiful.
Motorsport Pedigree and Performance
The GT3x draws its DNA from Bentley’s victorious return to endurance racing and the hard-fought GT3 championship series. Onyx leverages this race heritage, translating proven race engineering into a luxury road package.
As a result, the GT3x is always at home during supercar track days or at high-profile automotive events. Some owners even use their cars in exclusive time attack competitions, underlining its dual street and track persona.
Comparison With Rivals
Meanwhile, the Onyx GT3x competes at the upper echelon of custom grand tourers. Think along the lines of Mansory-tuned Bentleys, Brabus-modified AMG GTs, or Novitec’s widebody Ferraris. However, Onyx blends unique British character with greater exclusivity, making direct competition rare.
In addition, while most rivals focus on straight-line power, the GT3x brings balanced, track-bred capability and bespoke design.
Collector Appeal and Resale Value
Therefore, rarity and craftsmanship make the GT3x highly desirable for collectors. Early models already appreciate in value, thanks to limited production and strong demand in luxury markets.
Moreover, each bespoke configuration means even used examples hold appeal, as no two GT3x are exactly alike. Check trending GT3x values and available collector cars on sites like Dourado Cars.
