Reliant Sabre 4
Code Name (SE1)
Reliant launched the new Sabre 4 at the Earls
Court Motor Show in London in 1961. The Reliant Sabre was a two
seater open top sports car which was moulded in glass fibre. The Sabre received
a mixed reaction by the public and dealers alike due to the unusual elongated nose
with boomerang style chrome over-riders.

1961 Under the bonnet the Sabre
used the Ford Consul 375 engine, which was available with stage 1 and
stage 2 tuning modifications (at extra cost) made by reputable tuners
"Alexander Engineering". Stage 1 was mildly tuned
with a single-choke Zenith downdraft carburettor. The compression
ratio was 8.9 to 1 , as compared with 7.8 to 1 on the the standard
consul engine. At an extra cost of £52 & 10 shillings you
could have a Stage 2 engine, which included twin SU carburettors, which
would give more top end power and could make the Sabre achieve speeds
over the magic 100 m.p.h.

first the Les Ballamy independent front suspension system seemed
overcomplicated, but on the road it worked well and in conjunction with
the rear Girling combined coil springs and shock absorbers, plus the
modified live rear axle located by a Watts linkage the car was praised
for its virtually roll free cornering at high speeds.

Reliant entered the Sabre 4 in various rallies
including the 1962 Tulip Rally, 1962 RAC Rally, 1963 Ilfracombe Rally
and the 1963 Monte Carlo Rally with some success.
Towards the end of the
production Reliant introduced the fixed head version of the Sabre 4 and
a new short nose version was also available after much criticism of the long
nose cars.
At £1,128 the car was not the cheapest sports
car, fundamentally the Sabre was safe, fun to drive and economical to
run.
