# ADESS-03

The ADESS-03 is a Le Mans Prototype LMP3 built to ACO Le Mans Prototype LMP3 regulations. It was designed and built by ADESS AG. The car had its competition debut at the 2015 4 Hours of Fuji. The car also serves as a base for the GreenGT LMPH2G and H24 Hydrogen powered Le Mans Prototype.

## Development

In 2013, the ACO announced a new category of Le Mans Prototypes, known as LMP3, which would replace the previous Le Mans Prototype Challenge (LMPC) class in 2015. Initially, the car was meant to be made by LAS Motorsport, a joint venture between Sebastien Loeb Racing, ADESS AG, as well as SORA Racing. Under the initial agreement, Sebastien Loeb Racing would be in charge of development and assembly, while ADESS AG would be in charge of the design and homologation of the car, and SORA Racing handling production. However, when the car was launched on 9 June 2015, it was known instead as the ADESS-03, with no branding on the car from Sebastien Loeb Racing, SORA Racing, or LAS Motorsport. The car was had its first shakedown test performed at the Hockenheimring, on 16 September 2015 with customer AAI Motorsports. The car has been known to have reliability issues stemming from its driveshaft angles, as well as issues with its gull-wing style doors.

### GreenGT LMPH2G

The ADESS-03 Served as a base for the GreenGT LMPH2G, which was developed by GreenGT which in 2013 attempted to field a Garage 56 effort at Le Mans with a hydrogen-powered prototype, then known as the GreenGT H2, but did not ultimately participate in the race. The car is powered by a 650bhp hydrogen fuel-cell power plant, with power output capable of being increased by up to 335bhp through an energy-retrieval system.
During the weekend of the 2018 4 Hours of Spa Francorchamps, the car was demonstrated by former Le Mans winner Yannick Dalmas, while GreenGT also did demonstrations of refuelling in the pitlane. The car's hydrogen is contained in sealed tanks at 700-bar pressure. It was later announced that the car would participate in the pre-race proceedings at the 2019 24 Hours of Le Mans, with the car set to run a demonstration lap of the full Circuit de la Sarthe.

### ADESS-03 Evo

In late 2019, the ADESS-03 Evo, an updated version of the original 03, was released for use in the second generation of LMP3 competition.

### GreenGT H24

The ADESS-03 Evo also serves as the base for the GreenGT H24 car.
