The Aston Martin DB2/4 is a grand touring automobile produced by the British manufacturer Aston Martin between 1953 and 1955. It succeeded the original DB2 model and served as a transitional vehicle leading to the later DB4. The DB2/4 combined the Lagonda straight‑six engine of the DB2 with a new chassis, bodywork, and a four‑speed manual transmission, from which its designation derives (DB2 / 4).
Development and design
- Origins: Following the introduction of the DB2 in 1950, Aston Martin sought to improve performance and comfort. The DB2/4 was conceived as an evolution, retaining the 2.6 L (2608 cc) Lagonda straight‑six engine while incorporating a redesigned chassis and a four‑speed gearbox.
- Chassis: The DB2/4 employed a new tubular steel chassis that provided increased rigidity and a lower floor pan, allowing for a sleeker silhouette and improved handling.
- Bodywork: The car was offered with both factory‑built and coachbuilt bodies. The standard factory body featured a two‑door, four‑seat coupé layout with a fastback roofline. Several coachbuilders, including Zagato and Tickford, produced alternative bodies, such as the notable DB2/4 GT Zagato, which featured a lightweight aluminium shell.
- Transmission: The four‑speed manual gearbox replaced the earlier three‑speed unit, giving the model its “/4” suffix.
Technical specifications (standard DB2/4)
- Engine: 2.6 L (2608 cc) Lagonda straight‑six, dual‑overhead‑camshaft (DOHC) configuration, producing approximately 105 bhp at 4,500 rpm.
- Transmission: 4‑speed manual, rear‑wheel drive.
- Dimensions: Wheelbase 2,565 mm (101 in); overall length 4,500 mm (177 in); width 1,600 mm (63 in).
- Performance: Top speed of about 115 mph (185 km/h); 0–60 mph (0–97 km/h) in roughly 15 seconds.
- Suspension: Independent front suspension with coil springs; live rear axle with leaf springs. Braking employed drum units on all wheels.
Variants
- DB2/4 Mk II (1954): Introduced a larger 2.9 L (2912 cc) engine, raising output to roughly 125 bhp and improving top speed to around 120 mph (193 km/h).
- DB2/4 GT: A high‑performance, lightweight version produced by Zagato, featuring a shortened wheelbase, aluminium body panels, and tuned engine, achieving top speeds near 130 mph (209 km/h).
- Tickford Coupe: A bespoke version with a more muscular roofline and modified interior trim, built by the Tickford engineering division.
Production numbers
- Approximately 530 units of the DB2/4 were manufactured, encompassing all variants. Production ceased in 1955 when the DB4 entered series production.
Motorsport
The DB2/4 participated in several endurance and sports car events during the early 1950s, most notably the 24 Hours of Le Mans and the Mille Miglia. While it never achieved overall victory, its reliability and handling earned respectable class finishes. The Zagato‑bodied DB2/4 GT achieved notable success in European hill‑climb contests.
Legacy
The DB2/4 is regarded as a pivotal model in Aston Martin’s post‑war lineage, bridging the early DB series and the more celebrated DB4 and DB5. Its engineering refinements—particularly the adoption of a four‑speed gearbox and a more rigid chassis—laid groundwork for subsequent models. Surviving examples are highly valued by collectors, with coachbuilt variants such as the Zagato GT commanding premium auction prices.
