The traditional Blümel twin-spoke steering wheel was replaced by a more practical three-spoked leather-wrapped wheel,[6][7] which, as a result of the traditional Bristol badge being removed from the front of the car, was the only place where this badge was retained.

This edition was the first Bristol to possess the four-headlamp layout that was oddly anticipated by some of the company's earliest models, and to power this a bigger alternator was used.

By the time the larger engine was supplied to Bristol, the figures were quoted as net power outputs.

The rear lights were also changed using vertically mounted rectangular Lucas clusters, that carried over to the early 603 models.

The only engine is the fuel injected 5.9 litre Chrysler Magnum V8 as used in the later Bristol Blenheim, allowing for up to 400 hp (298 kW) depending on the customer's desires.
