This is the Hayera Turbo a cheap affordable sports-car with a 4,2l 6 sylinder twin turbocharged boxter engine wich produses 300hp wich also features a advanced all-wheel drive system with traction-control and ABS
To get 300hp, a 4,2l twin Turbo 6 cylinder is probably Overkill I would try making a smaller engine to get less weight or make more power out of the engine you have
i would recommend: better design (more fixtures, fascia) probably a more aggressive look, small spoiler instead of a lip, and probably a logo
im working on a redesign on the car and a new engine --- Post updated --- this is the new i4 Hayera turbo facelift
