The Series III Espada was introduced at the 1973 Turin show. It can be recognised by a mildly restyled nose and taillights, and a chassis number beginning with the number 9. The ZF power steering system was improved and air conditioning became standard equipment. Spring and shock rates were altered and brake power was increased.
The most obvious visual difference was once again found in the dash area. This now wraped around the driver and the centre console became more upright at the front. A sunroof became optional as did a Chrysler TorqueFlite automatic tranmission. 55 Espadas were built with this automatic, 5 of which were RHDs.
In order to meet US emission standards, a smog pump was developed that would cut out at high revs leaving maximum power output unaffected. Special carburators and ignition settings rounded out the system.
Five mph impact bumpers were added to the front and rear to meet US safety requirements. These later became standard equipment on all Espadas in 1976.
