Yes, following CLX's request that "it must be a season you have closely followed" I find it very easy to agree with Bernd about 1965 but ... whilst not really disagreeing with the assertion regarding the car with which ACBC equipped Clark that year, I've always felt that the
relatively most competitive 1.5 litre F-1 car Lotus produced was not the 1965 version of the 33, but the 25 in its 1963 guise. In 1963 BRM campaigned the P57 which was really past its use by date and were struggling to get the semi-monocoque and, initially, tortionally flaccid P61 up to snuff, whilst Forghieri's worked-over 156s were not really the answer.
By 1965, however, Clark had some significantly more vigorous machinery ranged against him. Sure, the 32 valve Climax, when it stayed together, gave Lotus the shove they needed to contend with the latest BRM engine and Ferrari's and Honda's V-12s, but in the 1965 iteration of the P261, Bourne had a beautifully slippery car, with lots of tortional rigidity and fine handling, whilst the 158 and 1512 Ferraris were powerful and thoroughly competitive cars.
I was privileged to be at both Clermont-Ferrand and Silverstone in 1965. In France, Clark raced in an elderly 25 (R6) with the 16 valve engine and annihilated everyone (except perhaps Stewart), whilst in England, Clark's Lotus 33 was really not (IMHO) faster than the BRM or Surtees' 1512 yet he was, IIRC, some 30 seconds up the road from Hill before the 32 valve Climax started to destroy itself.
Clark always drove exquisitely, but if there were degrees of exquisiteness (!), perhaps 1965 was the year when he
really showed what he was made of.
