Built to the Edge: Five F1 Cars That Were Too Fast for Their Own Good (Miami Grand Prix Week)
Quick Takeaways
- Some of the most significant Formula One cars in history were also the most dangerous — not because of poor engineering, but because the engineers pushed beyond what anyone fully understood.
- The 1970 Lotus 72, the 1974 McLaren M23, and the 1977 Brabham BT45B each redefined what an F1 car could do, and each paid a price for it.
- As the 2026 Miami Grand Prix weekend arrives, it's worth remembering that modern F1's remarkable safety record is built on hard lessons learned from cars exactly like these.
- Concours Photo Art's Racing Legends collection captures several of these machines in photographs taken at the events where they're treated with the reverence they've earned.
What Fast Actually Cost
This weekend, Formula One races in Miami. The circuit is temporary, the grandstands are immaculate, and the cars are the product of thousands of hours of computational fluid dynamics modeling, simulation work, and safety testing. Nobody seriously expects a driver to be injured in a way that ends a career, let alone something worse.
It wasn't always like that. The cars in Concours Photo Art's Racing Legends collection represent an era when the engineering was extraordinary and the consequences of getting it wrong were immediate and severe. These weren't reckless machines — they were the product of some of the best minds in motorsport. But the margins were different then, and the cars existed at those margins constantly.
The Lotus 72: Wedge Theory in Practice
Colin Chapman's 1970 Lotus 72 abandoned the conventional cigar-shaped F1 car entirely. It was a wedge — low at the front, rising toward the rear — with side-mounted radiators and inboard front brakes to reduce unsprung weight. It was also, by most accounts, extraordinarily difficult to drive. Jochen Rindt won the 1970 World Championship in the 72, and died at Monza during qualifying that same season when the front brakes failed under braking. He remains the only posthumous Formula One World Champion.
The 72 raced in various forms until 1975. It was refined continuously, but its fundamental character — fast, demanding, unforgiving — remained. Chapman was never much interested in building cars that were easy. He was interested in building cars that were fast enough to win.

The McLaren M23: The Car That Kept Winning
The McLaren M23 is, by any reasonable measure, one of the most successful Formula One cars ever built. Emerson Fittipaldi won the 1974 championship in it. James Hunt won the 1976 championship in it. It raced competitively for four seasons, which in Formula One terms is an eternity.
What made the M23 remarkable wasn't a single innovation but a quality of completeness. It was well-balanced, relatively reliable by 1970s standards, and responsive to development. The 1976 season — Hunt versus Niki Lauda, the fire at the Nürburgring, the rain at Fuji — remains one of the most dramatic in the sport's history. The M23 was at the center of all of it.

The Brabham BT45B: When Alfa Romeo Came Back
The 1977 Brabham BT45B represented Bernie Ecclestone's attempt to bring Alfa Romeo back to Formula One as an engine supplier after a multi-decade absence. The flat-12 Alfa engine was powerful and sonorous and also, by the accounts of everyone who worked with it, extremely heavy and prone to consuming fuel at a rate that made race strategy genuinely complicated.
The BT45B didn't win a championship. It occasionally won races, and it looked extraordinary doing it — the long, low bodywork designed around the Alfa engine giving it a profile unlike anything else on the grid. It's the kind of car that rewards being looked at carefully, which is exactly what a photograph allows you to do.

Bottom Line
The Miami Grand Prix will be decided by tenths of a second between cars that are safer, faster, and more technologically sophisticated than anything that raced in the 1970s. That's progress, and it's genuinely good. But the cars in these photographs represent something the modern sport has largely engineered away: the feeling that the machine and the driver were both operating very close to the edge of what was possible.
