In order to reduce more manufacturing and maintenance costs, we use a Venturi channel chassis to create downforce
This is why the CNR5 was able to run 6:30.265 on the Nürburgring Nordschleife

I can see elements of SF90 in the CNR5’s overall shape, and its powertrain is reminiscent of that of a Huracan STO, while the interior, with its central driving position, evokes the GMA T.50.

2018 Leisurely CNR4 Ultimate Evolution


As the last generation model to use the NC chassis, the CNR4 is the first to feature a number of new technologies, such as a carbon fibre monocoque and a carbon fibre body, which reduces the weight of the vehicle by almost 400 KG; In terms of aerodynamics, the ground effect is used for the first time, which increases the downforce of the vehicle by 40%, and the new all-wheel drive system increases the transmission efficiency by 20%.

The RV31 3.1-liter V6 twin-turbo engine continues to be used The new turbine was replaced, which reduced the weight of the engine by 10 kg For the sake of vehicle balance, we adjusted the power to 700 hp and 700 Nm, and extended the maximum power range, which allowed the car to push the tires to the limit without exceeding the limit, so that there was more time to open the throttle


Although we reduced the downforce by about 500 kg when we built the street version, the car also lived up to expectations and set a time of 6:15.013 on the Nurburgring
