X80 Proto in GTA 5

Overview

The X80 Proto is Grotti's Super class racer, styled after the Ferrari F80 concept and a GreenGT Le Mans prototype. Legendary Motorsport sells it for $2,700,000. Testing gives it 128.25 mph flat out and a 1:00.677 lap, race tier E. Tier E is a fair mid-pack result, though the top speed is one of the stronger figures in the class. It is all-wheel drive and seats 2, with a closed-cockpit, endurance-prototype shape that stands out from the road-going supercars around it. The Finance and Felony update brought the X80 Proto in June 2016, its exposed wheels and prototype styling easy to tell apart from every other Grotti Super class car once it settles into an ordinary garage for Los Santos Customs to service.
