The Brabham BT52 is the first turbo world champion: Gordon Murray's dart-shaped BMW rocket that took Piquet to the 1983 title — an icon of maximum-boost F1 whose ownership is really custody of a legend's engine.

## History

Ground effect's ban for 1983 blew up Brabham's planned car mid-winter; Murray's response became design legend: the BT52, a rear-biased dart with almost no sidepods, its masses concentrated over the driven wheels to exploit the BMW M12/13 turbo's savage delivery — a four-cylinder production-block engine credibly beyond 800 hp in race trim and far more in qualifying.

The 1983 season delivered history: Piquet won Brazil, Monza and Brands Hatch (BT52B spec), took the championship at Kyalami from Prost's Renault — the first drivers' title of the turbo era — while the team pioneered refuelling-and-tyres pit strategy that reshaped Grand Prix racing's tactics permanently.

Survivors split between BMW's and collectors' hands: chassis appear at Goodwood and demonstration programmes with BMW Classic's works support the type's gold-standard custody, and the ownership reality is engine-defined — M12/13 rebuilds live with a tiny specialist circle, demo boost is a fraction of period settings, and the car's value carries both Murray-design and first-turbo-title provenance.

## Palmarès

1983 Drivers' World Championship (Piquet) — the turbo era's first title — on wins in Brazil, Italy and Europe (Brands Hatch); constructors' runner-up; the pioneering of modern refuelling pit strategy — then a demonstration-circuit career under mostly works-linked custody.

## What to check before you buy

This is engine custody with a chassis attached: verify which specialist built and maintains the M12/13, its hours, boost configuration and spares position — BMW Classic association is the premium context. Chassis identities (BT52/52B) and Piquet race history are precisely documented; title-race cars sit at apex value. Realistic use is demonstration running; period qualifying boost is folklore, not an option. The market is thin, international and relationship-driven — cars change hands through BMW, auction houses and collector networks rather than open listings.

## Did you know

- The BT52 was designed in roughly three months after the flat-bottom rules leaked — Murray junked a finished car and drew a better one over Christmas.
- BMW's M12/13 block was a production 1500 casting, preferably seasoned — the first turbo title was won on an engine block related to road-going 02-series BMWs.
- Brabham's 1983 mid-race refuelling stops were a deliberate strategic weapon — the modern pit-stop war starts with this car.
