[TMS] BMW Unveils Sport Design Concept Car 'Concept 1 Series tii'
Bayerische Motoren Werke AG (BMW) of Germany unveiled a design concept car "Concept 1 Series tii" at the 40th Tokyo Motor Show.
Based on the "1 Series coupe," the concept car has a reduced vehicle weight and enhanced aerodynamic performance desinged for motor sports.
To reduce the vehicle weight, the car employs carbon fiber reinforced plastic (CFRP) for the front hood, side mirror cover, part of the front intake port and the rear bumper, as well as the gurney flap of the rear lid. The CFRP parts are finished with a clear matte coating. The coated front food has the effect of reducing the reflection of sunlight into the driver's eye, BMW said.
The front spoiler, side sills, rear bumper and rear lid have been redesigned to optimize the aerodynamic performance. The spoiler has a structure totally different from that of the mass production model.
It is provided with splitters (current plates for dividing air flow) on both sides. The splitter is slightly projecting forward and generates a downward air flow. Part of the air flow thus generated is supplied to the side intakes and the rest is flown under the body.
The car is equipped with two fins on the outer side of the front hood to improve the aerodynamic performance during high speed driving, thereby enhancing the stability. The gurney flap used on the rear lid is larger than that used in the standard model of the 1 Series coupe so that a greater downforce is generated in the rear part to enhance high-speed stability.
The seats were specially developed for sports driving. They are sports bucket seats made from artificial leather called Alcantara, in addition to natural leather. They have integrated headrests and built-in side airbags.
Also, bucket seats are employed for the rear seats. To reduce the glare and reflection of sunlight shone into the car, a wide sunshade band is provided on the upper side of the windshield and the dashboard is also made of black Alcantara.
