BRM

At precisely 12,000 rpm, the 1.5-litre (91 cu in) supercharged V16 engine of the BRM Type 15 did not merely rev; it violently tore the atmosphere to shreds. The shrieking mechanical howl was so viscerally terrifying that grown men would instinctively cover their ears in physical pain. This acoustic weapon was not merely a racing car. When driver Raymond Mays and engineer Peter Berthon established British Racing Motors in Bourne, Lincolnshire, in 1945, their mission was steeped in fierce post-war nationalistic pride. They sought to obliterate the grand prix dominance of Italian marques like Alfa Romeo, Maserati, and Ferrari. To achieve this, they formed a national trust backed by the United Kingdom’s foremost industrial heavyweights, from Rolls-Royce to Lucas. These titans donated bespoke components, funds, and aviation technology to construct the ultimate British racing machine. The BRM philosophy was stubbornly romantic: they would rather fail attempting an engineering impossibility than secure an uninspired victory.

That uncompromising ethos birthed the Type 15, the most complex racing car of its era. To meet the 1950 Formula 1 regulations, Berthon crafted a minuscule 1.5-litre (91 cu in) V16, forced-fed by a monstrous two-stage centrifugal compressor supplied by Rolls-Royce. It unleashed a terrifying 600 CV (591 bhp), delivering power with a sudden, vicious brutality that instantaneously converted rear tyres into plumes of pungent white smoke. Yet, bureaucratic paralysis delayed its debut for years. By the time legends like Juan Manuel Fangio and José Froilán González wrestled it onto the tarmac, its reliability was farcical. Just as they began to tame its lethal power delivery, the governing body abruptly shifted the 1952 regulations to 2.0-litre (122 cu in) naturally aspirated engines, rendering the shrieking V16 an obsolete museum piece overnight.

Crushed by its monumental inefficiency, the national trust collapsed. Salvation arrived in 1952 when industrial magnate Sir Alfred Owen purchased the Bourne operation. Owen injected ruthless financial stability and instigated a radical strategic pivot. Under brilliant engineer Tony Rudd, the team abandoned absurd complexity for the BRM P25, a nimble chassis clothed in lightweight aluminium and propelled by a remarkably simple 2.5-litre (153 cu in) four-cylinder engine. This pragmatic approach finally bore fruit in 1959, when Swedish aristocrat Jo Bonnier wrestled the P25 to BRM’s maiden Formula 1 victory at the Dutch Grand Prix.

When engine capacities were reduced to 1.5-litre (91 cu in) for 1961, BRM ascended to true greatness. They developed the sublime P56 V8 engine, famously mounted in the P57 chassis. Adorned with distinctive, organ-like “Stackpipe” vertical exhausts, it sounded like a frantic buzzsaw. Piloted by the fiercely determined Graham Hill, identifiable by his iconic midnight blue and white London Rowing Club helmet, Bourne engaged in a titanic, blood-soaked war against Jim Clark and Lotus. In 1962, this relentless pursuit culminated in ultimate glory: BRM seized the Constructors’ World Championship, and Hill was crowned Drivers’ World Champion. Throughout the early 1960s, BRM stood tall as a bona fide British superpower.

Their appetite for radical engineering extended beyond the grand prix circus. In the early 1960s, BRM forged a clandestine alliance with Rover to develop an endurance racing car powered by a gas turbine engine. The resulting Rover-BRM Gas Turbine was entered at the 24 Hours of Le Mans in 1963 and 1965. Driven by Hill and a fresh-faced Jackie Stewart, the experimental machine was eerily silent, emitting the sustained whoosh of a giant vacuum cleaner. Lacking conventional engine braking, it required a uniquely brave driving style, yet astonishingly survived the 1965 endurance classic to finish in a spectacular 10th place overall, proving Bourne’s capacity for boundless innovation.

However, when Formula 1 doubled capacities to 3.0-litre (183 cu in) in 1966, the old hubris returned with a vengeance. While Cosworth sensibly developed the simple, compact DFV V8, Bourne’s engineers seemingly lost their minds. They conceived the incredibly complex H16 engine, officially designated as the Type 75. It was essentially two flat-eight engines flattened and stacked, joined by coupled crankshafts, intended for the heavy, purpose-built P83 chassis. It was catastrophically heavy, unfathomably complicated, and disastrously unreliable. It secured only a single, freak victory, ironically powering a Lotus chassis driven by Jim Clark at Watkins Glen in 1966. The H16 project haemorrhaged cash, breaking the team’s financial spine.

Desperate to rectify this colossal blunder, Tony Rudd and Geoff Johnson designed a buttery-smooth 3.0-litre (183 cu in) V12 engine. While initially intended for late-1960s machinery, this Type 142 engine found its true calling after Rudd abruptly departed Bourne in 1969. It was brilliantly repurposed to propel the handsome P153 and P160 chassis, sculpted by newly arrived designer Tony Southgate. Thanks to the unrelenting talent of drivers like Mexican prodigy Pedro Rodríguez and Swiss master Jo Siffert, BRM enjoyed a brief, heroic twilight, securing mythical victories. The marque’s final, poetic triumph occurred at the 1972 Monaco Grand Prix, where Frenchman Jean-Pierre Beltoise drove a masterful race through torrential, biblical rain.

The subsequent demise was tragically rapid. Sir Alfred Owen fell gravely ill, and the Rubery Owen group unceremoniously severed its financial lifeline in the early 1970s. Owen’s brother-in-law, Louis Stanley, affectionately known as “Big Lou”, attempted to salvage the operation under the Stanley-BRM banner. Yet, they simply could not compete financially or technologically against the agile swarm of British kit cars utilising the cheap, bulletproof Ford Cosworth DFV engine. After enduring the humiliation of failing to qualify the dreadful P207 chassis, the Bourne factory finally closed its doors and folded in 1977.

Yet, true motorsport royalty never perishes completely. In the 2020s, the Owen family commissioned historic racing specialists Hall & Hall to construct three precise “Continuation” models of the original, savage V16, utilising thousands of original factory blueprints. Today, while the marque no longer contests the modern world championship, it survives as a living relic. At historic events like the Goodwood Revival, the earth-shattering shriek of the BRM V16 continues to paralyse crowds, ensuring the fiercely independent spirit of Bourne will never be silenced.
