In 1935 the 'Jaguar' name sprang upon
the scene for the first time with a completely new saloon and sports car
range.
William Heynes had been working to
produce a completely new box section cruciform braced chassis for a vastly
improved new model range. Meanwhile Weslake had been turning his talents
to the Standard engine and by adopting overhead valves he succeeded in
increasing output from 75 hp of the previous 21/2 litre sidevalve engine
to no less than 105 hp.
For the new chassis and engine unit,
Lyons designed a fresh body style, less flamboyant than previous models,
yet still stylish. Indeed it was closer to contemporary Bentleys which
cost nearly four times the price! Sophistication was increasing, and now
customers were offered four doors for the first time on an SS. Indeed so
different were the new models that it was felt that a new model name was
needed. The Company's advertising agency suggested 'Jaguar' and though
Lyons took some persuading, it was finally adopted. Thus the new cars
would be known as SS Jaguars. The 'Jaguar' name was an ideal choice for
feline grace and elegance, combining docility with remarkable power and
agility. The cars have matured and developed to justify the analogy in
every way.

With typical showmanship, Lyons had
arranged a lunch at the Mayfair Hotel in London to launch the new model to
the press a few days before the 1935 Motor Show. The SS Jaguar 21/2 litre
saloon was unveiled to much favourable comment and the assembled company
were asked to guess the price. The average guess was £632. The actual
price just £395. All the earlier SS designs had been superseded with the
exception of the larger Tourer body which lived on with a revised radiator
grille and the fitment of the new 21/2 litre engine. The superb new sports
car design, which had been glimpsed just briefly as the SS 90, reappeared
in similar form as the SS Jaguar 100. With a revised treatment around the
fuel tank area at the rear, and more importantly, the adoption of the new
chassis and engine, the company now produced a sports car to be proud of.
For many, the SS 100 is a pre-war
classic amongst sports cars. The price, incidentally, was just £395.
This new model was to be used to
considerable effect in competitions, both national and international. In
1936 the motoring journalist Tom Wisdom, driving with his wife Elsie, won
the International Alpine Trials in an SS 100. This car, which came to be
known as 'Old Number 8' was run very successfully at the Brooklands
circuit by Wisdom and in the Shelsley Walsh hillclimb by Coventry garage
and theatre owner, Sammy Newsome.
A year later a team of three cars was
entered by the factory in the RAC Rally, the premier such an event in
Britain. The team, which included the Hon. Brian Lewis (later Lord
Essendon) took the Manufacturer's Team Prize but outright success eluded
them. Instead the event was won by a privately entered SS 100!
A new, enlarged 31/2 litre engine had
been developed and tested in 'Old Number 8'. In September 1937, this
engine, together with a new 11/2 litre unit, joined the 21/2 litre version
in a completely revised model range.

The new models were not very different
in appearance, distinguished from their predecessors by the lack of the
side mounted spare wheel, but the range now employed 'all steel'
construction. Additionally the old Tourer was replaced by Drophead
versions of the saloon in each engine size.
Heynes had designed a further stronger
chassis for the new body construction resulting in more interior space and
bigger doors. Prices ranged from £298 for the 11/2 litre saloon to £465
for the 31/2 litre Drophead Coupe.
The new 31/2 litre engine was fitted to
the '100' model and this gave genuine sports car performance with sixty
miles per hour reached from a standstill in 10.5 seconds and a top speed
of over 100 mph. At £445 the bigger-engined SS 100 was in a class of its
own.
