The Elden PRH 16 is a jewel in the Elden crown. It is designed as a Formula 2 car with a chassis developed from the Mk 15 and was ordered by Tony Brise.

Changes from the Mk 15 include: an evolved monocoque chassis with a skin design that improved stiffness and accommodated Formula 2 regulations, twin fuel cell, all new wheels designed by Peter and fabricated by Dymag, bodywork modifications to accommodate the chassis changes and Formula 2 regulations yet still maintain the signature Falconer nose.

When Tony cancelled the order, Gordon Smiley became the customer and the car was finished as a Formula Atlantic with a Cosworth BDA 1600 engine and Hewland FT200 gearbox.
