[4] In 2013, to commemorate the 15th anniversary of the series, Polyphony Digital announced "Vision Gran Turismo", a special project featuring concept cars designed for the sim by automobile companies such as Alfa Romeo, Alpine, Aston Martin, Audi, BMW, Bertone, GM Design, Honda, Infiniti, Italdesign Giugiaro, JORDAN Brand, Mercedes-Benz, Nike, Nissan, Peugeot, SRT(Chrysler), Volkswagen and Zagato.This variant of the AMG Vision GT received a power increase to 441 kW (591 hp) and a sequential transmission, among with some aesthetic upgrades and a weight reduction of 85 kg (187 lb).This was a coupe modelled after BMW's touring cars from the 1970s, with plenty of aerodynamic elements and a 3-litre twin-turbo inline-six engine producing 404 kW (542 hp).It combines Subaru's signature flat-four engine and all-wheel drive layout with electric motors and a torque vectoring system.The fictional laser propulsion unit, claimed to be developed by Chevrolet, can be aimed at a specific point on the track surface for increased downforce.[24] It is a low-slung Le Mans Prototype powered by a Skyactiv rotary engine with unknown specifications, and draws inspiration from the company's own 787B Group C car combined with their current "Kodo" design language.The "Alpine Vision Gran Turismo Race Mode" is essentially the sportiest version, with an added rear wing for improved handling.The Tomahawks, having been designed for 2035, possess various technologies that cannot be attained at the present day, such as graphene bodies and tires that can withstand speeds of over 650 kilometres per hour (400 mph).The car served as a launch platform for Hyundai's N performance division, as well as a glimpse into the future of fuel cell technology in motorsports.For a vastly improved field of vision, the car is driven in a prone position (but from within a closed cockpit and using a steering wheel, unlike the Chaparral 2X), and it also possesses a hybrid system and lightweight structure.At its core a smaller version of the Honda NSX, it weighs just 903.6 kg (1,992 lb) and is powered by a mid-mounted 2-litre turbocharged inline-four engine producing 301 kW (404 hp).[57] Several of the Vision Gran Turismo cars have variants that have been modified and homologated to meet regulations for race classes, such as Group GT3 and WEC.On 24 November 2019 (the day of the 2019 FIA GTC World Finals), Lamborghini revealed the "Lambo V12 Vision Gran Turismo"—a single-seat performance car, loosely resembling a sports prototype, powered by the same V12 hybrid powertrain as the Sián FKP 37.Unveiled on 5 December 2021,[63] the Porsche Vision Gran Turismo is an electric two-seat sports car with mid-engined proportions and design cues from the brand's previous models, such as front quad-LED headlights, a rear light bar, and aggressively flared fenders.First appearing in the form of a highlighted silhouette in a Twitter teaser post from Kazunori Yamauchi on 21 May 2022,[67] the Suzuki Vision Gran Turismo was revealed in its entirety five days later.[68][69] This two-seat roadster, whose design was inspired by the Cappuccino and third-generation Swift Sport, possesses a hybrid system in the form of a 1,340 cc (82 cu in) Suzuki Hayabusa engine and three electric motors.It can be seen as the successor to the MR-layout Suzuki GSX-R/4 concept from 2001, which was also a lightweight roadster powered by a Hayabusa engine (although the VGT, hybrid system aside, uses an FR layout).[70][71] The internal combustion engine's power is delivered to the rear wheels via an 8-speed dual clutch transmission which Ferrari says has been adapted from their Formula One program.Similar in form factor to the Italdesign Parcour concept from 2013, the Exeneo forgoes windows in favour of solid carbon fibre and aluminum surfaces, and features an individual wheel drive (IWD) system, pairing a V10 engine with four electric motors to achieve a combined output of 910 kW (1,220 hp; 1,240 PS).[79] The X Gran Berlinetta is powered by a twin-turbocharged 3.3-liter Lambda V6 with electric supercharger technology producing 798 kW (1,070 hp; 1,085 PS), and can reach a top speed of over 400km/h.The car is described as an all-electric, all-wheel drive single-seater, inspired by the 1957 Škoda 1100 OHC roadster and designed by Oliver Stefani.Bertone also revealed plans for their unnamed Vision Gran Turismo car, hinted to have an unconventional three-wheeler-like shape and a highly futuristic design.
