The
first of the very successful DB4/5/6 line-up, featuring elegant
coachwork designed by Touring of Milan, Italy. The handmade,
aluminum bodywork panels were mounted on a steel tube frame,
using the Superleggera (meaning: super light) method of construction.
All round disc brakes fitted, made first by Dunlop and later
on by Girling.
There were five
series of the DB4, each series introduced changes and improvements
to the original series one cars. Early cars have a mesh grille
and simpler bumper design. Later cars are longer and consequently
heavier than early cars, some late series five cars had DB5
style headlamp covers.
All DB4s were powered
by a new six cylinder, all aluminum, 3670cc engine designed
by Tadek Mereck, developing around 240bhp.
The DB4 offered
excellent performance for the time, 140mph top speed and 0-60
in 8.5 seconds. Overdrive transmission on most cars, the gearbox
was produced by Astons' owner, David Brown. A Vantage engine
was also available, offering even higher power outputs.
