Introduced to the public at the London
Motor Show in 1953, the DB2/4 offered very much a first in the motoring
world - since then much copied. It's Aston Martin that we have to thank
for bringing the world the 'hatchback'. This came about as the DB2/4 was a
four seater (really a 2+2) unlike the pure two seat DB2, and rear access
was required for the occupants luggage. The roofline of the DB2/4 was
raised so as to provide extra headroom for rear seat passengers. Also the
windscreen became a single piece full width curved affair.

As well as the useful hatchback, the
DB2/4 can be distinguished from the earlier car by more substantial
bumpers with over-riders. Also the headlamps were repositioned slightly
higher as demanded by new safety regulations

Initially the 2/4 had as standard the
2.6 litre engine (2580 cc, VB6E/) in Vantage tune from the DB2 which
produced 125bhp. Then from mid 1954, an enlarged 2.9 litre (2922 cc,
VB6/J) was introduced giving 140bhp. This translates into a genuine 120mph
top speed.
