He was reserved where the cars were loud — an émigré engineer who signed his work in capacity and camshafts rather than chrome. The record below is set the way he kept it: applications, engines, displacements. The five files in the register document where the record met the road. The works record ## Applications, engines, displacements | Year | Application | Engine | Capacity | Output | | --- | --- | --- | --- | --- | | 1958 | DB4 | DOHC straight-six · all-alloy | 3,670 cc | 240 bhp at 5,000 rpm | | 1963 | DB5 | DOHC straight-six · triple SU | 3,995 cc | 282 bhp at 5,500 rpm | | 1965 | DB6 | DOHC straight-six · cross-flow head | 3,995 cc | 282 bhp at 5,500 rpm | | 1969 | DBS V8 · V8 Vantage | DOHC V8 · all-alloy, quad-cam | 5,340 cc | 380 bhp at 6,000 rpm | | 2017 | DB4 GT Continuation | DOHC straight-six · twin-plug | 4.2 litres | 340 bhp | Figures per the HICONIUM vehicle files. The 1969 line records the 1977 V8 Vantage state of tune; the 2017 line is a posthumous application of the 1958 architecture.

He earned the new engine by fixing the old one. ### The all-alloy six The DB4’s 3.7-litre twin-cam was drawn in aluminium with a seven-bearing crankshaft, wet liners and hemispherical chambers — a production engine specified like a competition one. ### Capacity in reserve The six grew from 3.7 to 4.0 litres without redesign, and the Continuation took the same architecture to 4.2. He drew the headroom in before anyone asked for it. ### The twin-plug head The DB4 GT’s competition engine fired two plugs per cylinder on his basic architecture — the version the 2017 Continuation returned to. ### The quad-cam V8 His second all-new Aston engine: 5,340 cc, all-alloy, four camshafts. Introduced in the DBS V8 in 1969, the year after he retired. ### The long service life Aston Martin kept his V8 family in production from 1969 to 2000. Few engineers have had two architectures carry one company for four decades.

Beyond the register ## From Longbridge to the last V8 ### '49–'57 #### Austin C-Series The 2.6-litre six from his Longbridge years — and a cancelled Austin V8 built from paired A40 units. #### Aston Martin DB Mark III The reworked Lagonda six: his apprenticeship piece at Feltham, reliability included. ### '59–'63 #### Aston Martin DB4 GT The competition evolution of his six, twin-plug head and all. #### DB4 GT Zagato The same engine under the lightest body the six ever wore. #### Lagonda Rapide The 4.0-litre six in a four-door Lagonda — the quiet application. #### Aston Martin DP215 A four-litre twin-plug development in the 1963 Le Mans project car. ### '65–'72 #### The V8 testbed DB5 A development mule with the new V8 where the six belonged. #### Lola T70 Mk III The Aston V8 raced before it was released — a bruising public shakedown in 1967. #### Aston Martin AM V8 The DBS V8 engine family carried on under the post-David Brown badge. ### '89–'00 #### Aston Martin Virage A revised descendant of the V8 architecture, twenty years on. #### V8 Vantage Le Mans The final derivatives of his V8, built until 2000. He had been gone eighteen years. The road ## Kraków, Longbridge, Newport Pagnell Pre-war ### Fiat & General Motors, Poland Engineering posts in Poland and Turin — and a parallel life rallying: Monte Carlo in a Fiat 508, a class win at the 1939 Rally Poland. 1941–’45 ### British wartime engineering Tank engine work in Britain after the escape from occupied Poland. 1949–’53 ### Austin, Longbridge Production engine work at scale — the C-Series six and the V8 that never was. 1954–’68 ### Aston Martin Feltham, then Newport Pagnell. Two all-new engines in fourteen years; he retired to Italy in 1968, before his V8 reached the road. In his words “I think it is better to hear good brakes squeaking than no brakes not squeaking!” Tadek Marek · AM Quarterly, 1967
