The Techrules Ren (stylized Techrules REN) is a single-door, high-performance sports car manufactured by Techrules, and designed by Fabrizio Giugiaro and Giorgetto Giugiaro of Italdesign. At its launch, it will become the first sports car to contain a turbine engine. This is also the first production sports car from Techrules. Expectations for the vehicle's construction are 10 (hand-built) per year.
Choice of name
The name "ren" is the first of five values that every Chinese person is born with to contribute to the society, and means humanity and kindness.
The exterior design was inspired by aerospace engineering, with the inclusion of a rear fin, and a cockpit-like cabin. The cockpit cabin will differ, depending on the number of chosen seats, from one to three. The chassis design was designed by L.M. Gianetti. The interior slightly represents the British-built sports car, the McLaren F1, with the inclusion of three seats, but this is only if the customer has chosen the option of three front seating. The interior also contains a denim material for the seats, which is constructed by high-end Italian clothing company, PT Pantaloni Torino.
The Ren is powered by a turbine and a lithium-ion electric motor, but there are three specification options, making the setups different. The option for a turbine-electric motor combination was, according to CEO Matthew Jin, to make the conversion process of freeing the combustion engine to convert chemical energy into mechanical energy more efficient.
There are three specification options. The first one contains the turbine and two electric motors, which does 429 hp (320 kW; 435 PS) and 575 lb⋅ft (780 N⋅m), which means the power-to-weight ratio sits at 252 hp (188 kW; 255 PS) per ton. This makes the car rear-wheel drive only. The second includes a turbine and four motors that boasts 858 hp (640 kW; 870 PS) and 1,150 lb⋅ft (1,559 N⋅m), making the power-to-weight ratio at 504 hp (376 kW; 511 PS). The final setup has the turbine and six motors, this time pushing 1,287 hp (960 kW; 1,305 PS) and 1,725 lb⋅ft (2,339 N⋅m), leaving the power-to-weight ratio at 757 hp (564 kW; 767 PS) per ton. These last two setups make the car all-wheel drive. The range (both turbine and electric motor, with diesel) is at 1,243 mi (2,000 km) with 80 litres of fuel. The electric range is 124 mi (200 km). The car can achieve 31 MPG. At the most potent form, the car's wheel torque can get to as high as 5,737 lb⋅ft (7,778 N⋅m) of wheel torque. Electric motor lifespan stands at 100,000 cycles, which makes the battery longevity something to be less worried about.
|“||Because turbines have always been a very inefficient way to convert chemical energy into useful, wheel-turning mechanical energy, only a few have tried to use a turbine in the powertrain system, and none have ever succeeded commercially. But, with electric vehicles, an electric motor is used to drive the wheels, which effectively frees the combustion engine to exclusively convert chemical energy into mechanical energy and finally into electric energy. This is a major breakthrough, making it possible for us to use the highly efficient turbine engine as a superb range extender on our vehicles.||”|

- The car was questioned of its use of the turbine engine in an interview with CEO Matthew Jin and Autocar. He explained that this was to make the conversion of freeing the combustion engine to convert chemical energy into mechanical energy be more efficient.
- The car was also featured in the 2017 Concorso d'Eleganza Villa d'Este.
