The Series 1 was introduced in March 1961, using the triple SU carburetted 3.8 litre 6-cylinder Jaguar XK6 engine from the XK150S. The first 500 cars built had flat floors & external bonnet latches. These cars are rare & more valuable. After that, the floors were dished to provide more leg room & the twin hood latches moved to inside the car. The 3.8 litre engine was increased to 4.2 litres in late 1964. All E-Types featured independent coil spring rear suspension with torsion bar front ends, & four wheel disc brakes, in-board at the rear, power-assisted from 1964. Jaguar was one of the first auto manufacturer to equip cars with disc brakes as standard. 1:76 scale
