The Ginetta F400, previously known as the Farbio GTS, and originally developed by Arash Motor Company as the Farboud GTS, is a sports car made by the British Ginetta Cars company. It was the first Farboud and Farbio planned for production until its sale to Ginetta in 2010.

The Farbio GTS was originally conceived in 2002 as the Farboud GT with an Audi-based engine. It was eventually launched in 2007 with sales from the beginning of 2008.

Three engine options were offered, with the GTS 260, 350 and 400. Both the GTS 350 and 400 feature a supercharged 3.0 litre Ford unit. The GTS 400 produces 384 bhp (286 kW; 389 PS) providing 0-60 mph of 3.9 seconds, with a top speed of over 175 mph (282 km/h). The basic GTS 260 model with 262 bhp (195 kW; 266 PS) could accelerate to 60 mph in 4.8 seconds.

The F400 sold few when production was halted in 2010 and the car underwent significant redevelopment to be relaunched at the end of 2011 as the Ginetta G60.
