[6] In September 2016, the company announced that it had built its 100th vehicle, which was an E10 R.[7] The car features an aluminium 'spine' to which a composite passenger ‘tub’ and front and rear subframes are attached.

[9] The composite ‘tub’ of the E10 is formed of a ‘sandwich’ that comprises a thermoset plastic core contained between sheets of carbon fibre.

It is estimated that the resulting material delivers 70% of the mechanical performance of ‘virgin’ carbon fibre at significantly lower cost.

[11] The car features inboard front springs and dampers and replaceable GRP body panels, which are intended to reduce repair costs in the event of an accident.

[21] Standard equipment levels are higher than those of the E10 and E10 S, and include six-speed manual gearbox, ventilated disc brakes and uprated four-pot callipers, and twin-skin composite seats with four-point racing harnesses.
