Same first-series Diablo basis, same doctrine: 5.7-litre naturally aspirated V12, 550 hp, gated six-speed manual, full carbon body at 1,540 kg. Nineteen will be built. 2026 · 19 cars announced · Serravalle, San Marino ## The second creation Three years after the coupé's Milan reveal and one year into its production run, Eccentrica announced its second model on 10 August 2026: a roofless Roadster on the same first-series Diablo basis, drawn again with BorromeoDeSilva and engineered under Maurizio Reggiani's advisory eye. The launch specification pairs pale glacier-blue paint with a red interior and white five-spoke wheels. Its first public showing comes this week at The Quail during Monterey Car Week — the same lawn where the drivable coupé debuted in 2024 and the Titano package in 2025. | Highlight | Detail | | --- | --- | | Roofless, not a cabrio | There is no folding top and no pretence of one — the Roadster is an open car in the speedster tradition, with twin roll hoops and intake pods where the Diablo's roof once was. | | Same analogue doctrine | Nothing about the drivetrain changed on the way to open air: the naturally aspirated V12, the gated manual and the 550 hp figure carry over from the coupé unchanged. | | 1,540 kilograms | The first exact kerb weight Eccentrica has published for any of its cars — full carbon body over the carbon-reinforced steel spaceframe, with a 41:59 weight distribution. | | Monterey debut | Announced digitally on 10 August 2026, the Roadster makes its first physical public appearance at The Quail on 14 August — nineteen cars, commercial terms still unpublished. | | Label | Value | | --- | --- | | Donor | Diablo, 1990–94 | | Series | 19 announced | | Press reveal | 10 August 2026 | | Public debut | The Quail, 14 Aug 2026 | | Body | Full carbon, roofless | | Price | Unpublished | ## Technical specifications ### Powertrain | Label | Value | Note | | --- | --- | --- | | Engine | 5,707 cc naturally aspirated 60° V12 | first-series Diablo donor unit | | Output | 550 hp at 7,000 rpm | 600 Nm at 6,500 rpm | | Gearbox | Close-ratio gated 6-speed manual | rear-wheel drive | ### Structure | Label | Value | Note | | --- | --- | --- | | Chassis | Steel spaceframe, carbon-reinforced | full carbon body, no roof | | Weight | 1,540 kg | 41:59 front-to-rear distribution | | Suspension | Double wishbones, semi-active dampers | | | Brakes | Brembo 380 mm front / 345 mm rear | 100–0 km/h in 34 m | | Tyres | Pirelli P Zero Trofeo R | 255/30 R19 front, 325/30 R19 rear | ### Performance | Label | Value | Note | | --- | --- | --- | | 0–100 km/h | 3.8 s | | | Top speed | 335 km/h | | ## Heritage > A roofless Roadster, not a cabrio — the Diablo's silhouette opened to the sky. > > > > Eccentrica, August 2026 ### Announced for Monterey 10 August 2026 The Roadster arrived as a press reveal four days before Monterey Car Week: renders of a pale blue open car above the clouds, a full specification sheet, and a 19-car allocation. The physical car shows publicly for the first time at The Quail on 14 August. The specification reads like the coupé with the roof deleted and the discipline kept: 550 hp at 7,000 rpm, 600 Nm, 3.8 seconds to 100 km/h, 335 km/h flat out — and 1,540 kg, the first kerb weight the marque has ever published. ![Eccentrica V12 Roadster in pale glacier blue with red interior, elevated front three-quarter view](https://hiconium.dev/images/cars/eccentrica-v12-roadster/press-front-three-quarter.jpg) ![Eccentrica V12 Roadster rear three-quarter view on a mountain road above the clouds](https://hiconium.dev/images/cars/eccentrica-v12-roadster/press-rear-clouds.jpg) ![Eccentrica V12 Roadster seen from behind, twin roll hoops and intake pods over the open cockpit](https://hiconium.dev/images/cars/eccentrica-v12-roadster/press-back-detail.jpg) ### Roll hoops, red leather, a gated gate The open cockpit Where the Diablo carried a roof, the Roadster carries two sculpted hoops with intake pods between them; the engine breathes through what used to be the cabin's ceiling. The launch car's red leather cockpit sits open to the air, the gated shifter exactly where the coupé keeps it. Eccentrica has published no price and no delivery schedule — nineteen cars are announced, and the commercial conversation starts on the lawn at The Quail. ![Detail of the Eccentrica V12 Roadster roll hoops and intake pods behind the open cockpit](https://hiconium.dev/images/cars/eccentrica-v12-roadster/press-roof-detail.jpg) ![Eccentrica V12 Roadster cockpit with red leather, carbon console and gated manual shifter](https://hiconium.dev/images/cars/eccentrica-v12-roadster/press-dash.jpg) ### Milestones | Date | Title | What happened | Standing | | --- | --- | --- | --- | | 10 August 2026 | Press reveal | Eccentrica announces its second creation: a roofless V12 Roadster, 19 cars, full specification published, price withheld. | | | 14 August 2026 | The Quail debut | First physical public appearance at The Quail, A Motorsports Gathering, during Monterey Car Week. | | ## Member instruments A HICON Bid is a confidential expression of buying interest on this file.
