Working
from experience with the Lotus 12 and also the successful Vanwall, for whose
chassis design he had been responsible, Colin Chapman introduced the complex
Lotus 16 to Grand Prix racing at Reims in 1958. Frank Costin designed the new
car’s body, and it was no surprise that the family resemblance to the Vanwall
was unmistakable.
Chapman’s
concept of the 16 was a very light car with a competitive power-to-weight
ratio. The body shape was intended to reduce drag and give a high maximum
speed, and the all-independent coil-spring suspension was intended to promote
superior road-holding in corners. To achieve a low frontal area the Coventry-Climax
engine was canted at 17 degrees to the nearside, and raked at 10½ degrees to
the car’s centreline to run the propellor shaft down its left side. This
allowed the driver to be seated low down beside the shaft. The drive-line was
complex and the Lotus-developed gearbox which had a gearchange similar to a
motor-cycle was to prove extremely troublesome – as it had in the earlier Lotus
12s.
The
Lotus 16 seldom made a great impression, and its Chapman strut rear suspension –
subsequently adopted on the road-going Elite – proved too efficient for the front
suspension. The car tended to unstick its front wheels first, and was plagued
by understeer throughout its one-and-a-half season life. Graham Hill, Innes
Ireland, Cliff Allison and Alan Stacey drove the cars – Ireland putting in the
best performance on his Grand Prix debut when he finished fourth in Holland.
The
Donington car is No. 363 - the very first Mark 16 – and after performing nobly
in historic racing events in the hands of John Le Sage it was acquired by Tom
Wheatcroft in first-class condition.
