Czinger 21C review: flat out in America's £1.6m, 3D-printed hypercar Reviews 2025
A closed loop, AI-driven approach that eliminates expensive tooling costs, allows rapid iteration and creates perfectly optimised, lightweight components through 3D printing. Over the past five years I've visited several times and watched this bold project turn from sci-fi into reality.

In 2024, sister company Divergent's facility was simultaneously producing parts for Bugatti, Aston Martin, McLaren, SpaceX and the military. Next door at Czinger the 21C was entering the final phase of development, too. Divergent has invested around $1 billion in its visionary Divergent Adaptive Production System and the Czinger 21C is intended as a lap record destroyer to showcase the full extent of its powers. Today, it's time to drive. Does it look as exotic in the metal as in pictures?
On a cool, hazy morning at Sonoma Raceway, the 21C looks almost as alien as the sprawling weblike structures beneath its carbon fibre bodywork. It's wide and incredibly low but with an SR-71 Blackbird inspired '1+1' seating arrangement, the passenger cell is slim and has an organic, teardrop shape. Of course, aside from Top Gun vibes and the perfection of a central driving position, the configuration is also fantastic for aero optimisation. Is it a downforce monster?
Czinger claims 1,200kg of downforce at 100mph and 2,552kg at 200mph. Open up the rear deck lid with the gorgeous and vast swan neck rear wing (which balances out the massive front splitter and dive planes), and beyond the distractingly beautiful suspension rockers and subframe you'll find the engine. How complicated is the powertrain?
At its heart lies a 2.9-litre twin-turbocharged V8 producing 750bhp and 397lb ft. It revs to 11,000rpm and drives through a seven-speed single clutch, but twin-barrel gearbox. The internals are by XTrac and the casing is 3D printed in house. The engine is supplemented by an 800V electric drive system consisting of a crank-driven MGU that can deliver up to 200bhp into the battery and two further electric motors for the front axle, powered by a small but power dense 4kWh battery split and located in each sill.

Total output is 1,250bhp and 692lb ft. Czinger claims 0–60mph in 1.9 seconds and 0–124mph in 4.8 seconds. About a second quicker than the Ferrari F80. What's it like to sit inside?
Press a little rubber button located at the very rear of the double length door in the gaping side intake and the journey into a whole new world begins. The billionaire door rises up and the driver's seat feels a very long way away. Czinger's support team suggest sitting on the wide carbon fibre sill, then swinging legs across and down into the footwell.
It's not the most elegant process but access is considerably easier than the Aston Martin Valkyrie, for example. And the view is worth the effort. You sit so far forward that the wheelarches don't frame the view ahead. Instead they're just in your peripheral vision.
So, it's just the small lozenge shaped wheel, the simple, clear screen beyond it mounted on a 3D printed structure and the road ahead. Fittingly, you feel right at the front of a very fast projectile. The jet concept seems like something a seven year old might come up with, but aren't supercars and hypercars meant to bring out the kid in all of us? Job done.

Senators ask US to probe data security issues with DeepSeek
Aug 5 (Reuters) - A group of seven Republican U.S. senators on Tuesday asked the Commerce Department to evaluate potential data security vulnerabilities posed by Chinese open-source AI models like DeepSeek. The senators including Jon Husted, Ted Budd and John Cornyn want the Commerce Department to detail any threats from data collected by applications being fed back to Chinese servers or whether the AI models are feeding American personal or enterprise data to China's military or to companies with Chinese military ties. Commerce Secretary Howard Lutnick said in January it appeared DeepSeek had misappropriated U.S. AI technology and vowed to impose restrictions.

Lucra Taps Autosana to Turbocharge QA with AI
NEW YORK, NY, August 5, 2025 (EZ Newswire) -- Lucra, opens new tab, the leading provider of social gamification technology, today announced a strategic partnership with Autosana, opens new tab, a platform for AI-powered UI testing, as part of Lucra's broader efforts to integrate AI thoughtfully and selectively across its product development pipeline. Initial results from the pilot are already driving meaningful impact: Lucra has significantly reduced the manual workload required to validate product releases—freeing up engineering and quality assurance resources while increasing overall test coverage. 'With over 15 years in mobile development, I've seen firsthand how painful and time-consuming UI testing can be—especially for end-to-end flows,' said Michael Schmidt, CTO of Lucra. 'Autosana is a game changer. It's the first solution I've used that makes robust, automated UI testing truly accessible. We were able to automate the majority of our regression suite in a matter of hours instead of weeks or months, and the self-healing capabilities mean we spend far less time maintaining brittle tests. It's saved our team countless hours already and fundamentally changed how we approach QA.' Lucra's current regression suite includes over 250 manual test steps, requiring 1–2 hours of effort for each full run. In under 15 hours of work, the team has already automated approximately 70% of these steps using natural language instructions. Compared to the months of setup required for traditional UI test scripting—work that previously consumed nearly a full-time engineer—the return on investment has been immediate. Autosana's self-healing architecture has eliminated the brittleness of legacy UI testing frameworks. As Lucra continues to expand test coverage, the QA team is now able to focus more on feature validation and bug identification—while overnight test cycles handle regression automatically. This partnership is part of Lucra's deliberate approach to AI—investing in purpose-built tools that deliver real operational value while continuing to build proprietary systems internally. By combining thoughtful external integrations with in-house innovation, Lucra remains committed to delivering best-in-class technology to its partners and users. About Lucra Lucra is the leading provider of social competition services, offering hospitality, entertainment, and media brands the ability to natively integrate competitive gameplay into their digital platforms. Clients like Five Iron Golf, Puttshack, Backyard Sports, Dave & Buster's, TouchTunes, and more use Lucra's white-label technology to power tournaments and challenges, build loyalty, and drive new revenue.

US proposes new rules to speed drone deployments
Aug 5 (Reuters) - The U.S. Transportation Department on Tuesday is proposing new rules to speed deployment of drones beyond the visual line of sight of operators, a key change needed to advance commercial deployments like package deliveries. Under current rules, operators need to get individual waivers or exemptions to use drones without visual line of sight. The department said eliminating those requirements "will significantly expand the use-case for drone technologies in areas like: manufacturing, farming, energy production, filmmaking, and the movement of products including lifesaving medications." The proposal includes new requirements for manufacturers, operators, and drone traffic-management services to keep drones safely separated from other drones and airplanes. Association for Uncrewed Vehicle Systems International CEO Michael Robbins praised the risk-based proposal as "a critical step toward enabling drone operations that will enhance safety, transform commercial services, and strengthen public safety with drones as a force multiplier."
