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  The Sketch - Wednesday 05 August 1931
