The V12 Diablo Restomod Of Your Dreams Is Almost Ready For The Street

The Lamborghini Diablo–based Eccentrica V12 has been teasing us for years now, but the limited-production ’90s restomod is almost ready for the street. Eccentrica announced it was entering the final phase of testing for the V12 before it starts production in September, meaning the first customer cars – each with a price tag exceeding the Revuelto – could be hitting the asphalt in time for the end of summer. The company plans to bring a pre-production example to The Quail, a Motorsports Gathering during Monterey Car Week in August. And if we’re lucky, we might even get to drive the thing.

The Powertrain Is Ready For Prime Time

Eccentrica’s most recent round of testing took place between October 2024 and May 2025, with five separate testing sessions that included trips to the dyno, some proving grounds, and track-day sessions on an open course. The company said that the evaluations yielded the car’s final engine package, which includes revised camshafts, bigger airboxes, and a bespoke engine computer calibration. Eccentrica says the 5.7-liter V12 found in its restomod will make more power across a wider rev range than the engine found in the original Diablo donor vehicle – though without specifying which trim that refers to.

For comparison, the 5.7-liter Diablo SE30 Jota made 595 horsepower and 471 pound-feet, making it the most powerful of the original Lamborghini-built cars despite later models sporting a larger 6.0-liter V12 engine. Meanwhile, the first run of Diablos made 485 hp and 428 lb-ft, while the later SV bumped the horse count to 510. Given Eccentrica’s flair for the dramatic thus far, we suspect it’ll aim to beat out the Jota with at least 600 hp, but that’s pure speculation.

If you bought a Lamborghini Diablo in the 90s, you’re in luck because prices are reaching well over half a million at auction in 2024.

Applying The Finishing Touches

The Eccentrica V12 – the car, not the engine – still needs some finishing work. The company says it will devote the month of June to final tuning of the gated five-speed manual gearbox and suspension. The car’s semi-active shock absorbers come from supplier TracTive, and they include a sophisticated multi-axis G-meter and software to provide damping valve adjustment in just 10 milliseconds. The TracTive units also feature a five-setting save function, which we presume will come with pre-selected parameters by Eccentrica.

The company says its goal with the V12 restomod is to elevate the experience of the car, rather than “chase quadruple-digit horsepower or hybrid lap records.” That means the Diablo will only come with traction control – not stability control – to keep the experience raw and unfiltered. And four-piston Brembo calipers chomp down on 14.0-inch brake calipers, although there’s no word on if the ABS found on later Lamborghini Diablos will make it to the Eccentrica. In a concession to pseudo-modernity, the V12 does get hydraulic power steering that reduces kickback over the barely boosted helm of the original.

The former F1 racer’s ownership makes this a truly special Lambo.

Once the Eccentrica V12 hits customers’ hands, the company will reportedly start work on its next project. Just as the Murcielago succeeded the Diablo, the next V12-powered restomod will reportedly be based on Lamborghini’s “batmobile.” We’re as excited for that one as we are to see the Eccentrica V12 cruising around California’s central coast this summer.
