SCG stated that a production version of the Arrow would consist of a track only version with a V12 engine, code named 'Titan,' in 2017, followed by a road going version called the Apollo S with a twin-turbocharged V8 engine, and that both models will “utilise the chassis technology developed for the SCG003C”, but as of 2018 neither model has reached production stages primarily due to the management of Apollo Automobil focusing on the development of a separate model the Intensa Emozione.

[2] The Arrow concept is powered by a 4.0 L, twin turbocharged Audi V8 that is rated at 735 kW (999 PS; 986 hp) and 999 N⋅m (737 lb⋅ft) of torque.

[3] Power is sent to the rear wheels through a 7-speed CIMA sequential manual transmission.

[1] The Arrow is built on a tubular chromoly space frame combined with a carbon fibre tub, the design of which is a modified version of the one used in the original Gumpert Apollo, and subsequently the 2016 Apollo N concept.

[4] Apollo claims the Arrow weighs under 1,315 kg (2,900 lb).
