1964-1966 Lotus Elan S2
In November of 1964 Lotus upgraded the Elan to S2 specification that included better Girling Disc brakes and numerous body changes. It was also the car that brought Lotus back into full-scale production and so they began to offer more options.
The S2 was was also the first model available with an S/E package. The S/E was a heavier car with some interior appointments such as safety belts and deluxe carpeting. It also got a “C” camshaft that raised power to 115 hp and a dual-circuit master cylinder with vacuum assist.
The S2 introduced a full-width veneer wood dash with a lockable glove compartment. The car also got clustered rear tail lights.
For the S2, Lotus cast their own block as Ford stopped production of the Ford Cortina 116E. The new 2731E block was virtually identical, but the cylinder-head featured a new stiffening rib between spark plus #2 and #3. Detail upgrades included iron tappet sleeves, stronger 125E connecting rods and a 6-bolt flywheel.
