The modifiction to the radiator, which allowed the bumper to slip under it, was dictated by US regulation
that required a bumper to be fitted that would absorb an impact of 5 mph without causing permanent
damage to the vehicle.

Those cars not destined for the USA received a front air dam. This hinted at the extensive wind tunnel testing
to which the car had been subjected, where the installation of this item had convinced designers of the need to
provide better stability at high speed.

The driver found several particular changes that made it more comfortable to drive in traffic.
The recirculating ball steering of the earlier models had been replaced by a rack and pinion arrangement.
The new unit felt crisper and reacted more quickly. The latter resulted from the newly tuned front suspension which led especially to a more precise wheel attitude.

Combined with the gear selector was a switch for speed control, which enabled a chosen speed to be
maintained without operating the accelerator pedal. The dashboard had a new layout. In a similar manner
to that of the Bentley of the period, guages for oil pressure, cooling system temperature, fuel and generator
were combined in one circular instrument, rather than being scattered in the form of single units over the facia.
