The engine man
Kraków-born, Fiat- and GM-trained, a Monte Carlo rally driver before the war and a tank engineer during it, Marek reached Aston Martin in the mid-fifties and gave the company both of the engines its golden era ran on: the all-alloy twin-cam six of the DB4, DB5 and DB6, and the 5.3-litre quad-cam V8 that stayed in production until 2000.
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
| 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.
The register
1958Engine designer · Aston Martin
Development began in 1956 under John Wyer, with Harold Beach on the chassis and Touring of Milan on the body. Marek supplied the heart: a new 3,670 cc all-aluminium twin-cam six that gave the fresh platform its defining mechanical identity.
1963Engine designer · Aston Martin
No clean sheet — an enlargement. For the Frankfurt debut of September 1963 the six went out to 3,995 cc with triple SUs, and the most famous Aston Martin of all ran on capacity Marek had designed into the architecture from the start.
1965Engine designer · Aston Martin
The mature form of the six: four litres, alloy block, cross-flow head, carried in standard and higher-output Vantage states of tune. The DB6 proved the architecture flexed across specifications without complaint.
1969Engine designer · Aston Martin
William Towns’ DBS arrived with the six in 1967 and gained Marek’s 5,340 cc all-alloy quad-cam V8 in 1969 — the fastest four-seat production car of its day, and the start of an engine line that ran to the final V8 Vantage derivatives in 2000.
2017Original engine designer · Epilogue
Thirty-five years after his death, Aston Martin built twenty-five track-only DB4 GTs around a 4.2-litre, 340 bhp development of his twin-plug six. The drawings had headroom left in them half a century on.
Engineering signatures
His first Aston job was the old Lagonda 2.9 six for the DB Mark III — stiffer crankcase and crankshaft, revised liner sealing, new head and manifolds. He earned the new engine by fixing the old one.
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.
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 DB4 GT’s competition engine fired two plugs per cylinder on his basic architecture — the version the 2017 Continuation returned to.
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.
Aston Martin kept his V8 family in production from 1969 to 2000. Few engineers have had two architectures carry one company for four decades.

The same engine under the lightest body the six ever wore.
The 4.0-litre six in a four-door Lagonda — the quiet application.
A four-litre twin-plug development in the 1963 Le Mans project car.
A development mule with the new V8 where the six belonged.
The Aston V8 raced before it was released — a bruising public shakedown in 1967.
The DBS V8 engine family carried on under the post-David Brown badge.
A revised descendant of the V8 architecture, twenty years on.
The final derivatives of his V8, built until 2000. He had been gone eighteen years.
The road
Pre-war
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
Tank engine work in Britain after the escape from occupied Poland.
1949–’53
Production engine work at scale — the C-Series six and the V8 that never was.
1954–’68
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!”
