Riley Plus and Plus Ultra
The Riley Monaco was improved for 1930-1, with an
enlarged full-width rear boot, improved
roofline, larger doors hinged to the rear, and new
rotax headlamps that dipped onthe nearside. This
was followed within the year by a metal
pannelled version available rather than the fabric.
For an extra £27 these could also be supplied as a
special model with duplex shock absorbers and a spring
steering wheel plus twin zeniths with a lofty speed
advertised of 65mph.
Introduced at the 1931 Motor Show, the ‘Plus Ultra’ Series of the Riley Nine featured a number of improvements, the most significant being the new dropped chassis frame. The 4 seat Tourer version continued the theme established with the successful Mk lV and ‘Plus’ models which ran from 1929 – 31.For the next year 1931-2 The Monaco became a half pannelled Weymann construction and the diamond logo was also indicated by the four windows producing a diamond shape in their framing and also the bonnet louvres and was sold as the 'Plus Ultra'.

Motor Dicta. By Heniochus. Riley Nine Monaco Saloon.
The Plus series of Riley "Nine" (h.p.) Monaco saloons
has proved very popular this year. Among the special
qualities which have recom mended this car to a
fast-increasing number of owners are the wider
coachwork, stainless steel shell for the radiator and
other bright parts, petrol tank at the back instead of
on the dashboard, grouped oil points, Leveroll sliding
seat-fittings, and improved springs with silent bloc
rubber bushes. Another item is that one can buy the
single-carburettor-engined model for £325. The
two-carburettor model is rather faster but, as a
matter of fact, I do not think that the ordinary owner
will find it worth while to pay its additional price.
While petrol is now reduced to is. 2½d.
(1p) per gallon, the standard 9-h.p. Riley Monaco
saloon is very economical to run. Driven hard, taking
full advantage of its rapid acceleration to hustle
along at 60 miles an hour when ever possible, one can
travel 35 miles to the gallon on this Riley. At the
same time, using the four-speed gear-box, one can
start and attain 50 miles an hour in about 40 seconds.
That is all right for getting off the mark in a hurry,
and no one really wants to better that per formance in
everyday touring. My advice to Riley Nine owners is to
refrain from thrash ing such a willing engine, and to
drive it normally at 35 to 40 miles an hour on the
open road, instead of the 50 m.p.h. Another feature of
these Monaco saloons is the comfort of the Moseley
float- on-air cushions provided for the seats. Also I
like the full door-openings, so that passengers and
driver alike have easy access to their seats. At the
same time, the Riley Nine must only be looked upon as
an occasional four seater. It is really a car for
two," with extra seating capacity for friends. The
real four-seater is the Riley Six." That is a peach of
a car for four. But I have already ex pressed in this
column, some weeks ago, my pleasure in driving this
model, so need not repeat it here. from
